Short bobs are very versatile cuts for thin hair. No matter your texture, you can switch to shorter locks even if you have super fine hair. By cutting hair to your chin and going shorter towards the nape of the neck, you get a more full-bodied effect.
2020’s bangs aren’t baby bangs and they aren’t curtain bangs. They sit just right above the eyebrows, making them a bit shorter than previous trendy styles. A celebrity haistylist Gibson cut this fringe on Jaime King but warns short bangs are a lot of work for certain hair types. “I think hair texture plays a part in how short you can go with bangs,” he says. Keep in mind that curly textures tend to shrink as they dry, so when your stylist is cutting, be sure your hair is dry. “I cannot stress this enough. If you trim wet bangs, they’ll shrink when they dry and be too short,” Gibson previously told Allure.

Bob Cut with Blunt Ends: Short hairstyles for fine hair can make you look very polished and put together, especially with locks that are cut at one length. Because your hair is on the thinner side, blunt ends will provide just the right amount of density and structure for a fairly full, not poofy look.

Simple tricks for styling thin hair from ladies who actually have thin hair.
Unfortunately, lifeless strands that have a tendency to sit flat often come with the territory of having thin, fine hair. And although your hair might not be as luscious or as full as you would like, that doesn’t mean you can’t fake a thicker style with a few handy tips and tricks. But how can you make thin hair look thicker? What are the best haircuts for thin hair? And what are the best hairstyles for thin hair? Below we’ve collected thin hair how-to styling videos. We’ll update it this collection periodically.
How To Curl Fine Hair and Make it Stay
Tip: How-to-have-healthy-heat-styled-hair rules:
Invest in your flat or/and curling iron. Make sure to purchase one that says “ceramic plates,” which will ensure that the heat is evenly distributed.
A heat protector is a must!
Make sure the temperature is right for your hair. You’ll need an iron with variable heat settings in order to control it (so look for that feature at time of purchase). This is a big one. My hair should only be ironed at a low setting, below 200 degrees, as it is very fine. Start at a lower level and increase as needed.

How to curl fine hair with a curling iron.
If your hair is fine, fragile or color treated, use a low heat setting — below 200 degrees — to avoid burning or damaging your hair. As you curl your hair, notice how it responds to the heat and increase the temperature accordingly. Never go above 300 degrees.

Easy updo hairstyles for thin or baby fine hair
Tasha has naturally baby fine hair and shows how she styles them in three different ways.
Note: This video tutorial is in Russian but with English subtitles.
People with naturally thick hair are lucky. Their hair almost always looks good and their styling lasts much longer. Fine hair does require more work. But don’t despair!
You know of course that not every model or acctress has beautiful, full hair. This may be every woman’s dream, but in fact, for most women, especially those with fine hair, it’s an illusion that has to be created.
There are two types of fine hair:
The first is when you have plenty of hair but each strand is baby fine.

2. The second and most difficult hair to deal with is sparse and fine hair.
This kind often looks like see-through hair or hair that sticks to the head moments after the blow dry.
Princess Charlene of Monaco has sparse and fine hair but her hairstyle is always sophisticated.
Here are some easy tips to make your fine hair look its best.
The finer and more sparse your hair, the more essential it is to have the right haircut.
There are many variations of the bob, from layered to the most traditional one-length Vidal Sassoon signature cut. You must find the one that suits your face shape. I would rather see hair look a little thin than cut painfully short. Short hair don’t suit all face shapes.
Yolanda Hadid always looks sophisticated and classic. Her hair is naturally fine. She keeps it above shoulder length these days. It allows her to have different hair styles.
The big bang cut is perfect for woman with fine and sparse hair.
With this haircut, the bangs start almost at the crown of the head. This gives thinning or baby fine hair the illusion of fullness and is extremely chic.
“Bangs create a distraction by diverting the eye. It gives fullness to the front where the eye automatically goes at first glance and instinctively,” says Juan Carlos Maciques, hair wizard behind the stars like Jennifer Lopez and Michelle Williams, in InStyle magazine. From soft curtain bangs to a side-swept fringe, you can choose what your cup of tea is.
Actress Rashida Jones
The pixie is a very good haircut for thin, thinning or fine hair.
You can wear it combed or messy and it always look great. But you must have a good face shape for this cut. Warning! It will accent a sagging jaw line or a drooping chin.
Robin Wright
Carey Mulligan
Victoria Beckham
People with naturally thick hair are lucky. Their hair almost always looks good and their styling lasts much longer. Fine hair does require more work.
It requires frequent shampoos and needs to be restyled more often to look its best. But don’t despair! There are many beautiful women with less-than-perfect hair. They just know how to make it look its best. Just remember that Victoria Beckham, Charlize Theron, Cameron Diaz and Paris Hilton all have fine hair. They also have some of the best looking hair in Hollywood.

Let’s be clear on one thing: Being born with super-thick, flowing, supermodel-esque hair may afford you more options, but there’s no reason fine-haired ladies need to throw in the towel. Much of beauty is about optical illusions. Just like the right lipstick can make your lips look fuller and the right eyeliner can make your peepers pop, the right haircut can transform thin or fine hair into a (seemingly) thick, voluminous mane.
Using the advice of a few trusted stylists, we put together this roundup of the three best haircuts for thin hair—with lots of photos to prove it. These simple, yet strategic haircuts and hairstyles will trick onlookers into believing you have more hair than you know what to do with.
1. Blunt Cut Bob
Long locks can weigh down any look, so keep fine hair shoulder length or above. The trick for pulling off a shoulder-length style is making it a blunt cut. Blunt lines make your hair appear thicker.
Tip: To maintain and amplify fullness, avoid overtexturizing hair with lots of layers.
Cate Blanchett‘s blunt bob looks the epitome of chic, especially with her low side-parting and impossibly shiny blonde. Cate always keeps her naturally fine hair shoulder length or above.
Sleek and razor sharp, there’s a simple elegance to Rosamund Pike‘s immaculate bob.
Take inspiration from another of Charlize Theron‘s short hairstyles. This bob, cut level with her chin and styled with a side parting, perfectly frames her face.
Another actress to embrace the blunt cut bob is Saoirse Ronan, whose laser-cut style was a lesson in precise hairstyling. Wear your hair super sleek with a centre-parting to follow her example.
Here’s a style thick-haired women have a harder time pulling off: short hair tucked behind the ears. Thicker hair tends to stick out more and doesn’t stay behind the ears as well, but thinner hair sits smoother.
Loosely slicking your hair back is a perfect hair style for fine hair. Yolanda Hadid is a big fan of slicking her fine hair back for special occasions.
The wavy bob has become the hottest hairstyle obsession for women of all hair types, but it’s especially popular for those with thinner hair because it’s short enough to never fall flat, and the wavy texture gives the illusion of thickness. For added dimension, add highlights.
2. Choppy Pixie
Shorter hair is stronger than longer strands, so even very fine hair can benefit from a super-short cropped cut. Pixie cuts can actually make your thin hair appear thicker than it really is.
To feminize a boyish pixie cut, like Robin Wright‘s, blow-dry bangs to the side using a small round brush.
Want to look like Charlize Theron? (Don’t we all?) The trick to keeping hair like hers modern and youthful is using products that add toughness and texture. That means picking lightweight waxes or pomades and tossing anything you associate with sleekness, like gel or frizz fighters.
Michelle Williams has rocked a pixie cut since 2007, and has been sporting the short look ever since. It almost seems unnatural to imagine Williams without her Mia Farrow-esque pixie, but it looks like she’s in the stages of growing it out now. Michelle Williams has a bob now, proving that the in between growout period doesn’t have to be completely painful.
3. Shoulder Length Hair
Another trick to try if your hair is on the longer side is the deep side part. With a deep side part, you’re essentially lumping all your hair together on one side, creating the illusion of volume. You also create lift at the roots.
Amber Valletta has beautiful hair. It is naturally fine and wavy. The deep side part works perfectly for her.
Paris Hilton has fine and straight hair. The side part hair style works perfectly for her. She usually wears hair extensions but you can spot her sometimes without them.
What You Need to Look for On Your Hair Product Labels
Takeaways:
The ingredients in any hair care products are listed in order of concentration: from highest concentration to lowest concentration
Use water soluble silicones, especially if you have thin or fine hair
“Sulfate Free” does not always mean that the product is free of sulfates. Read your labels carefully
Avoid parabéns
Silicones
Why do cosmetics manufacturers use silicones?
Silicones have been incorporated in personal care products since the 1950s. Initially used in skin care products, and more recently in hair care applications, silicones are recognised for their lubricating properties and for the characteristic soft smooth feel they create (comb-ability, reduced friction and breakage). While silicones that made it to your product shelf are considered safe to use, not all silicones have been created equal. Long-term effects of usage, including build up and hair brittleness have been gaining more and more prominence recently.
In response, beauty industry has introduced what’s known as “water soluble silicones” to address negative effects of non-soluble silicones while also keeping its benefits, especially to those of us with thin or fine hair. In hair care, cosmetic manufacturers add silicones to shampoos, conditioners, and styling products to help create the slip needed to detangle and give hair a silky shine and manageability. Let’s look at how silicones types differ.
Water soluble silicones
The name is the give-away – a water-soluble silicone is the one that it is able to dissolve in water. It is a silicone that is easy to wash out of the hair using mild-shampoos or conditioner-only techniques and which does not leave a heavy buildup.
Hydrolyzed Wheat Protein Hydroxypropyl Polysiloxane
What does the “PEG” and the number mean? It’s important! Let’s say you have PEG-12 Dimethicone. That means that 12 molecules of polyethylene glycol were reacted with 1 molecule of dimethicone. The higher the number, the more soluble the oil (and silicone is essentially an oil). That’s because there are more of the water-soluble ingredients -the “PEG,” relative to the water insoluble dimethicone. For example, PEG-8 Dimethicone is slightly less water-soluble than PEG-12 dimethicone, which is slightly less water-soluble than PEG/PPG 15/20 dimethicone.
Non-soluble silicones
These are silicones that cannot be removed or penetrated with water, which can inadvertently damage the hair. This happens by silicones “sticking” to the hair surface creating a plastic-like film, preventing strands to absorb water, air and nutrients. They are removable with Sulfates, but in turn, the frequent use of Sulfates dehydrates the hair. It becomes a vicious cycle.
Silicones to Avoid:
All ingredients that contain the following words.
botanisil
cone (for example, avoid “Cetearyl methicone“)
dimethcione
dimethicon (for example, avoid “dimethiconol”)
microsil
silane
silicon
siloxane
siloxysilicate
silsesquioxane
silylate
Sulfates (and other cleansers)
“Sulfate free” doesn’t always mean sulfate free. When advertisers label “Sulfate Free” at the very front, they are referring to one of the harshest Sulfates: Sodium Lauryl Sulfate. However, this does not mean that the product is entirely free of Sulfates. On several occasions, we have found other drying Sulfates in the list, despite the “Sulfate Free” label.

Soap
Why You Should Avoid Soap On Your Hair?
Soap is much worse for your hair than sulfates. It can be much more harsh than sulfates in all scientific tests of harshness that we have seen. It is also alkaline. The pH of hair is 5.5 and most good quality cleansers are around that as well. But soap is usually 8 or more. This can damage hair badly, leaving it dull and dry. For skin soap can be fine, as skin can recover from the damage. But hair is not “alive” and cannot.
We detect soap by looking for the following, but this may not catch all soap. We recommend contacting the manufacturer to ask if something contains soap:
potassium hydroxide
saponification
saponified
saponifying
soap
sodium carboxylate
sodium palm
Parabens
Parabens are a common category of preservatives used in cosmetics and hair care products. Compared to other, safer alternatives, they are cheaper, and mimic anti-microbial agents in plants. However, they also have the ability to mimic estrogen and cause breast cancer. Research has found that parabens and mineral oil may cause considerable damage to the hair and scalp. Today, there are many other safer alternatives to such ingredients.
Risks associated with Parabens
Parabens are supposed to inhibit microbial growth in common cosmetic products like lotions, creams, scalp cleansers and so on. However, they may also disrupt the normal hormonal cycle of the body. As mentioned above, parabens can mimic estrogen and reduce the production of this important hormone in women. This increases the risk of breast cancer. Parabens are being suspected to be the cause of early puberty in girls as well.
Parabens are easily absorbed through the skin. It is due to this reason that they can harm the scalp, which is an extension of the skin. In a recent study, parabens were found in the urine and blood of healthy males after using paraben-based products. Using products containing parabens may also cause low sperm count and testicular cancer.
Parabens are hard to spot
A lot of the risk associated with parabens is that they are found under a range of compound names. Some commonly found parabens are
Butylparabens
Propylparabens
Methylparabens
Alkyl parahydroxy benzoates
Witch Hazel
Most types of witch hazel contain alcohol. Contact the manufacturer to see if the witch hazel in this product contains alcohol. Even if it does not contain alcohol, many people find witch hazel drying. Use with caution if you have hair prone to dryness.

Your hair’s pH balance plays a vital role in overall natural hair health
Despite what the hair product packaging might declare about “fruit extracts” or being “sulfate-free,” the single biggest factor determining whether a shampoo will make your hair shiny, manageably and healthy is its pH level.
For those who didn’t ace science in school, pH is a numeric scale ranking how acidic a substance is. Anything with a level under 7 is acidic, and solutions with a pH more than 7 are labelled basic or alkiline.
The scalp pH is 5.5, and the hair shaft pH is 3.67.
Shampoos at a lower pH (4.5 – 6.5) preserve your hair and scalp’s natural oils, which exist to protect against frizz-causing damage.
Note: It’s likely safe to keep products in this range if you have delicate, thin or fine, breakage-prone or damaged hair.
At the optimal pH, shampoo doesn’t completely remove all the natural oils, so you avoid over-drying the scalp, something Dr. Barbara Olisio, a cosmetic scientist who formulates hair and skin products, says causes “a vicious cycle that actually triggers more sebum production.”
The scalp and hair have an efficient mechanism to protect itself that is based on lipids, functioning at its best at low pH. At low pH, the hair cuticles are well-sealed so that the hair is stronger and shinier.
Determining a shampoo’s pH level ( or acidity) is hard, unless it’s clearly labelled on the bottle. There is no legal obligation for the industries to mention pH level on the label.
Some are, by the way, while others claim to be “pH-balancing” but remain shady about the product’s exact level. Here are some helpful resources:
MSDS/SDS Safety Data Sheets: These will have the pH or pH range of the product listed. Cosmetic companies should have these available for consumers to access. Not all can be found online, but with a little digging you can find them for the majority of products.
Note: pH is given in a range because it may vary from batch to batch or product to product, though the pH needs to be in a specific range in most cases in order for preservatives to be effective and the product to be stable on the shelf.
Test pH at home:
Get yourself some pH strips in the aquatic pets section of a pet store or the swimming pool section of a department store, or from your local drugstore. Make sure they measure below pH 7 as well as above.
Please note that conditioner often gives a less-than-accurate reading because it’s not all liquid (there are fats in there). But you can get a rough idea.

Scientific Research about pH and Hair
Scientists from the Department of Dermatology, Instituto de Dermatologia Professor Rubem David Azulay, reviewed the current literature about the mode of action of a low-pH shampoo regarding the hair shaft’s health and analyzed the pH of 123 shampoos of international brands. [PubMed]
Alkaline pH (>7 pH) may increase the negative electrical charge of the hair fiber surface and, therefore, increase friction between the fibers. This may lead to cuticle damage and fiber breakage. It is a reality and not a myth that lower pH of shampoos may cause less frizzing for generating less negative static electricity on the fiber surface.
All tested shampoo pH values ranged from 3.5 to 9.0.
Only 38% of the popular brand shampoos presented a pH ≤ 5.0.
Pediatric shampoos had the pH of 7.0 because of the “no-tear” concept. 100% of the children’s shampoos presented a pH > 5.5.
Detailed explanation on topics that get asked about a lot. This one is about shampooing/cleansing.
CLEANSING
Cleansing is what you do to remove styling products, sweat, dirt, etc. There are a number of products you can use to do this, which we will explain below.
Sulfate or “clarifying” shampoos Surfactants are ingredients that make your shampoo lather up and get sudsy. There are loads of different types of surfactants, and not all surfactants are bad.
SLS (sodium lauryl or laureth sulfate) is one of the most commonly used surfactants, but it is generally super drying and can strip all the oils and good stuff out of your hair, so you don’t want to use anything containing it frequently.
Basically, anything ending in “sulfate” is a “bad” surfactant, with some exceptions. If you’re unsure about a product ending in “sulfate,” search for info on it here or on other haircare forums, or try to figure out what type of surfactant it is (anionic, amphoteric, cationic, or nonionic).
Nonionic surfactants are generally the most gentle, and most “bad” surfactants are anionic.
For the purposes of this guide, we are going to refer to these types of shampoos as “clarifying” shampoos, since that is how you should use them, even if the product isn’t labelled as a clarifying shampoo.
Sulfates are super effective at removing product buildup, especially from silicone ingredients, from your hair. So if you use styling products that contain silicones or other buildup-causing ingredients, then you are going to need to use a clarifying shampoo every now and then to remove buildup.
You also usually need to use a clarifying shampoo when you switch to a silicone-free routine, even if you weren’t using sulfates before, just to remove any leftover silicone buildup.
Any regular shampoo that does not have the words “sulfate-free” on it, will work.
Non-sulfate surfactant (“sulfate-free”) shampoos
These use ingredients that are surfactants, but not “sulfates,” to get sudsy. Anything under the “surfactant” sections on this list is a surfactant. Coco betaine is probably the most common non-sulfate surfactant.
These shampoos can still be drying but are usually gentler, and are what you should use if you feel that you need to shampoo every day. They can also be somewhat effective at removing product buildup, except that they won’t completely remove silicone buildup.
There is some variety within this category, but this basically refers to cleansers that are sold as a cleanser but don’t lather up. this includes “no-poo” products, which are non-lathering cleansers that still strip your hair enough that you need to follow with a conditioner, as well as “cleansing conditioners,” which are usually a one-step thing that leaves your hair feeling clean but not stripped enough that you need to follow with a separate conditioner.
co-washing this just involves using straight up conditioner to cleanse your hair. this is probably the most gentle option, and is great for people with dry, frizzy/curly, or coarse hair that needs a lot of moisture. You can use any conditioner for this, as long as it doesn’t contain any silicone ingredients (see note on silicones at the bottom of this post).
literally any conditioner that doesn’t have silicones in it
CONDITIONING conditioning is what you may or may not need to do after cleansing to add some moisture back into your hair and smooth/”seal” the cuticle. you should definitely condition after any lathering (surfactant-containing) cleanser. you only need to condition after using a non-lathering cleanser if you feel like you need to, and you obviously don’t need to condition after co-washing.
whether or not something is labelled as a “deep” conditioner or “hair mask” is pretty much irrelevant. you can use a “deep conditioner” every day if you want. you can “deep condition” with your regular daily conditioner by leaving it on for a longer time than usual or putting a shower cap and/or hot towel over it. you can DIY a deep conditioning treatment or hair mask with food in your kitchen. you can do one of these kinds of treatments whenever you want to feel fancy, and they can help keep your hair nice and soft and happy, but always remember that no product or magical DIY recipe you found on pinterest is going to actually undo damage.
NB on silicone ingredients see the silicone section of this list. any silicone ingredient listed is “not soluble in water” can only effectively be removed buy sulfates and is one you definitely want to avoid. the silicones listed as “water soluble” are debatable. because they are water soluble, you don’t necessarily need to use sulfates to remove them, so you are less likely to get buildup. it’s not as important to avoid water-soluble silicones in conditioners or styling products, but you should be on the lookout for them if you start experiencing buildup.
