If you have very thin and fine strands, a sparser head of hair or both, one of the best shampoos for fine hair is an important inclusion in your routine. Often designed to help amplify volume, they offer thorough cleansing without weighing finer hair down.
Several factors can contribute to fine or thinning hair, including genetics and hormones. I've experienced hair thinning firsthand, plus my strands are slightly wavy, bleached and get greasy super quickly. Essentially, I'm very familiar with the ins and outs of a good shampoo for fine hair. As any hair expert will tell you, the key to achieving healthier hair is using products that have been formulated for the unique needs of fine and thinning hair, be they the best shampoo and conditioners or styling products.
In other words, if you have fine strands or are noticing your hair getting increasingly thinner (or both), it's vital you curate a haircare regime that supports this. To that end, in this guide I've reviewed the best products to help boost finer strands, with a view to help give your scalp nourishment, support healthy growth and inject volume. (And when you're done here, there are also the best conditioners for fine hair to pair with your new shampoo.)
Best shampoos for fine hair deals
The best shampoo for fine hair and thinning hair, tested by our beauty experts
RRP: £30
With nourishing ingredients like rice amino acids, shea butter and aloe vera leaf extract, this shampoo made our hair feel super silky and instantly thicker. The formula is light as a feather and formed a lovely lather, which made our hair and scalp feel squeaky clean – and it smells truly delicious.
Although this shampoo isn't very budget-friendly, we loved the instant lifting effect it had on our hair. Even while it was wet our hair felt thicker and, after testing it both before air drying and blasting hair with the best hair dryer for fine hair, the results were incredible. We also found our scalp and hair still fresh as a daisy the morning after we used it, plus strands had a whole lot of bounce, volume, density, and thickness.
Reasons to buy: Deep cleansing, adds volume
Reasons to avoid: Not budget-friendly
RRP: £46 for 236
Those who like shopping for "clean beauty", sulphate-free shampoos and eco-friendly beauty products will love how New Wash cleans and conditions the scalp and hair without harsh detergents. At first, it felt a little unusual to us as it's got quite a thick consistency, almost like conditioner, so we had some concerns that it might weigh our hair down initially.
Washing this product out took slightly longer – Hairstory suggests using its Massaging Scalp Brush, which was also a lovely treat. The product smells lovely and clean, with a subtle, baby powder-like scent, leaving our hair with boosted volume and body both when we blow-dried it and after allowing it to air dry. There wasn't a hint of oiliness in our scalp until the evening of day two after washing – a first for our tester.
Reasons to buy: Shampoo & conditioner in one
Reasons to avoid: Expensive
RRP: £7.49 for 385ml
OGX's Biotin and Collagen Shampoo harnesses the power of both biotin for hair (AKA vitamin B7) and collagen to help swell strands from the inside. This shampoo is very much on the thicker side, – unlike the gel-like consistency of Living Proof's Full Shampoo, for example – but we found its texture to be very nourishing. We also noticed it imparted a slight extra bounce, which is always welcome.
That said, having hair that gets greasy quickly, this shampoo wasn't the best on our list for thorough scalp cleansing; by the end of the day, our hair already had a bit of oiliness to it. However, if you're on a budget and looking for the best drugstore shampoo for fine hair that will also help your hair retain bounce, this is a solid option and very reasonably priced.
Reasons to buy: Affordable; sulphate-free
Reasons to avoid: Thicker texture won't appeal to everyone
RRP: £29 for 236ml
Living Proof's volume-boosting formulas often feature guides to the best hair styling products and haircare buys – with good reason. Not only do they smell great, they pack a punch, too; the Full Shampoo is a great example of why they're worth the investment. Yes, it is more expensive, but a little goes a long way so it lasts well.
This particular formula has an almost gel-like consistency, which was very gentle and light on our tester's fine hair. It also smells lovely and fresh, leaving our hair feeling smooth and not at all weighed down – though it's recommended for use alongside the matching conditioner for best results.
Reasons to buy: Smells great, refillable bottle
Reasons to avoid: More affordable options available
RRP: £27 for 250ml
Creators of some of the industry's best scalp treatments – and the iconic Elasticizer mask – the trichologists at Philip Kingsley are extremely well acquainted with the most pressing needs of both our scalp and our hair.
Although this shampoo contains sulphates, which can leave hair feeling overly cleansed and brittle, this particular product doesn't and is still among the best shampoos for thin hair. This is thanks to ingredients like keratin and natural cellulose; the latter helps to plump the surface of each strand to give it a more luscious, bouncy and shiny appearance. This formula is super light and has a subtle floral scent, something we also enjoyed, plus it was also really gentle on our scalp while cleansing.
Reasons to buy: Volumising; smells great
Reasons to avoid: Contains sulphates
RRP: £39 for 250ml
Shout out to our fellow greasy-haired beauty fans who load up on the best dry shampoos for oily hair. While our beauty editor's K18 review examines the brand's hero hair mask, the deep-cleansing Peptide Prep Detox shampoo is a lesser-known buy from the brand – but it's a real godsend.
When we tested this shampoo it whisked away all excess oil, product residue and sebum and we were amazed that it clarified so intensely without stripping our scalp and hair of moisture – remarkably, it didn't affect its colour, either. Being a clarifying formula, the brand recommends using it once a week to help prevent your hair from becoming too dry – but if you experience a lot of build-up more regularly you may want to try using it more frequently. Either way, this is the best deep cleansing product we've ever used.
Reasons to buy: Good for coloured hair
Reasons to avoid: Not for everyday use; expensive
RRP: £10.99
Shea butter can easily weigh finer hair down, but having used this product many times over the years we can testify that we didn't experience this at all. There's a lovely clean smell from this product, which we enjoy.
The shampoo itself is medium density and a little goes a long way, yielding a lovely lather that gently cleaned our scalp. Our hair was left feeling particularly soft and lifted from the inside out. The conditioning properties also help avoid stripping curly hair types – so if you've got a bit of a wave or tight curls, this formula won't be too stripping.
Reasons to buy: Affordable, great for coloured hair
Reasons to avoid: Packaging isn't very luxe
RRP: £28.25 for 250ml
Kérastase's Densifique Bain Densité is an ultra-nourishing shampoo that we found really locked moisture into our hair, thanks to the lightweight-yet-nourishing power of hyaluronic acid. It cleansed brilliantly and left out hair with a great amount of lift.
It's also one of the few shampoos for fine hair we tested that left us feeling like we could skip conditioner – which may be a plus to those with particularly oily hair like our tester. The only issue we could potentially see with this product is its perfumed scent, which some may find overpowering or not to their tastes.
Reasons to buy: Instantly adds volume
Reasons to avoid: Scent may be too overpowering
RRP: £44 for 250ml
This paste contains fine sugar crystals that gently exfoliate, while rassoul clay and rose extracts work to detoxify and nourish both the scalp and hair. It has a fairly unusual texture and appearance (it looks like actual mud), but when we emulsified it in our hands with a little water it foamed up nicely. All that clay absorbed excess oil well and gave our hair a lovely boost, too.
This product also smells absolutely heavenly and thoroughly cleansed our scalp, leaving our hair feeling as clean and healthy as can be. However, we definitely needed to use conditioner after using this particular shampoo, particularly as our hair has dry ends; the cleaning is thorough. We stayed loyal to the brand and used the Christophe Robin Delicate Volumising conditioner, which left our hair silky smooth but not weighed down.
Reasons to buy: Exfoliating, foams well
Reasons to avoid: Not great for dry hair
How we tested the best shampoo for fine hair and thinning hair
A selection of the shampoos tested for this guide
Well versed though I am in choosing and using the best hair products for very fine hair, I took on the task of testing several shampoos for consideration for this guide to ensure it was as well-researched as possible. To write a detailed and refined guide to the very best options, I tried dozens of products at various price points.
I tested each formula for several days, using each one both with and without conditioner, to get a clear understanding of how they made my hair look, feel and behave post-wash. I also looked closely at each product's packaging, how much of the formula I needed to cleanse my entire scalp and head of hair and how well the results lasted until my next wash.
Many shampoos for fine and thinning hair are a little more expensive than other formulas, so you might be wondering if expensive shampoo is better. In my honest opinion, if you have thin hair and can spend a little extra on your haircare products, it's an investment you won't regret. Pricier shampoos sometimes stretch further and therefore last longer, but these brands may also be more transparent about the ingredients used, while many formulas are gentler on your strands.
How to choose the best shampoo for fine hair and thinning hair
When shopping for a shampoo that'll suit fine and thinning hair particularly well, as well as my own first person insights, the following factors are all important when deciding if a formula will be a good fit.
- Cleansing: It's important for your chosen product to cleanse well enough to help remove any build-up on the scalp. As an excess of grease can show more easily on fine hair, so deeply clarifying and removing build-up is an important part of your haircare routine.
- Consistency: Anything with oils, butter or simply a heavier consistency in general is a huge no-no for very thin and/or fine hair. These can weigh down strands and also cause more scalp build-up, which can even impact healthy hair growth.
- Formula and ingredients: It can be as important to consider what's in the shampoo as it is to consider what's not in it. Ingredients like protein, vitamin B5, lactic acid and hyaluronic acid can all benefit fine hair. However, silicones are film-forming and can be heavier on the hair when they build up over time (a good clarifying shampoo helps here). Sulphates can give a very thorough cleanse but can also strip more moisture from weaker strands; shopping for the best sulphate-free shampoo for fine hair is worth bearing in mind should you experience this.
What ingredients can boost fine hair and thinning hair?
A good first step in improving a routine for fine hair is looking at the ingredients of the products in your haircare regime. "Specific ingredients, like caffeine, are linked to hair growth and can provide invigorating effects," says Tyler Moore, expert stylist at Live True London. "Lighter moisturising ingredients like aloe vera and hyaluronic acid can [also] provide hydration without weighing your hair down."
Leading trichologist Ricardo Vila Nova tells us that there are many volumising products on the market that contain polymers, which build density and texture. But when it comes to rebuilding and strengthening the internal bonds of the hair, he says: "I always suggest products with protein or lactic acid if we’re dealing with fine, dry hair."
A shampoo containing all the right ingredients for thin hair is helpful, healthy growth also comes from within, says Lauren Marr, artistic colourist at Gielly Green. She suggests a healthy diet that is "high in proteins, leafy greens and vitamins to naturally increase hair volume."

What ingredients should you avoid with fine hair and thinning hair?
It may be beneficial to avoid certain ingredients when looking for shampoos that work best on fine and thinning hair. "Avoid deep-cleansing shampoos containing salicylic acid as [this] may tangle the hair," Vila Nova advises. Moore also recommends avoiding ingredients such as oils and butter if your hair is on the fine side. "These can work well in hair masks and oil treatments, but in daily use shampoos and conditioners, these will weigh your hair down and cause it to become oilier faster," he explains. "These include coconut oil and argan oil."
Some people find that sulphates aren't the best match for their delicate hair. "They strip the hair of its natural oils, which can make your hair dry and [result in] flyaways," Marr says. "This can also cause scalp irritation."
What's the best way to shampoo and condition fine hair and thinning hair?
As Vila Nova explains, when washing fine hair you should distribute the shampoo evenly on the scalp and massage "thoroughly yet gently so as not to tangle [the] middle lengths and ends."
Incorporating a bit of scalp massage into your routine is not only nice self care element, it can also increase blood flow to the scalp. This, in turn, can benefit your hair's health and support its growth. The best way to massage your scalp is to use the fingertips of both your hands and apply gentle pressure on your scalp, moving them in small circles.
Moore adds that temperature is also important and that it's best to wash with lukewarm water to avoid damage and breakage. "Make sure to wet your hair thoroughly before applying shampoo to ensure the hair shaft [or] follicles will be open enough to absorb the product and also to create a good lather," he says. "After one-to-two minutes, rinse your hair thoroughly with lukewarm water."
How often should you wash fine hair and thinning hair?
The answer to the age-old "how often should you wash your hair" question varies depending on your hair and scalp type – whether you're more oil-prone or have a dry scalp – as well as your lifestyle and haircare routine. "There is no set rule on how often one should wash the hair, but fine hair usually requires more frequent washing to help build structure and volume," says Vila Nova.
"Those with finer hair might find their hair getting oiler quicker due to product build-up," Moore adds. "Products can weigh down fine hair, causing it to look greasy faster, even if you are prone to a drier scalp. Oil build-up will also look heavier on finer hair, meaning you might need to wash every one to three days depending on your personal preference."
