5 best shampoos for hair loss that help reduce thinning and shedding from the scalp
Shedding more than usual? These expert-approved shampoos can help!
Hair loss and thinning can be frustrating, emotional, and, unfortunately, incredibly common. Whether you're spotting extra strands in the shower or noticing your ponytail feels thinner than it used to, it's no wonder shampoos for hair loss are some of the most searched-for products in beauty. But how much can a shampoo really do?
According to leading trichologists, shampoos aren't miracle workers, but they can play an important supporting role. “Shampoos can’t create hair growth,” leading trichologist and founder of Act+Acre, Helen Reavey, previously told Cosmopolitan UK. “However, they can absolutely support it.” Creating the right scalp environment is key, with Reavey adding that “a good shampoo removes build-up and balances the scalp microbiome, creating the ideal conditions for healthy follicles.”
Ingredients matter, too. Trichologist Hannah Gaboardi also previously spoke to Cosmopolitan UK, highlighting stimulants that can help encourage healthier growth. She notes that “ingredients like peppermint and caffeine help the blood flow increase to the scalp, which allows the follicles to receive healthy nutrients and oxygen.” When it comes to minimising breakage, Gaboardi says keratin “helps strengthen the hair shaft, reducing breakage and leaving a thicker feel.”
For those experiencing hair loss, formula weight is just as important as what's inside the bottle. “The right shampoo can definitely help give fine hair temporary body and bounce,” says Anabel Kingsley, consultant trichologist and Brand President at Philip Kingsley, advising shoppers to look for shampoos containing thickening proteins.
Ahead, we break down the five best shampoos for hair loss to help support stronger, fuller-looking hair, one wash at a time.
Created by leading trichologist Helen Reavey, Act+Acre takes a scalp-first approach to hair loss – and it shows. This shampoo is powered by plant-based stem cells to help protect follicles from environmental stress, while caffeine and niacinamide energise the scalp and support healthier circulation. Hyaluronic acid is also included in the formula, delivering lightweight hydration to help to prevent dryness and irritation that can contribute to breakage.
Designed to optimise scalp health rather than promise overnight growth, this shampoo creates the ideal conditions for stronger, fuller-looking hair over time.
Key ingredients that reduce hair loss: Caffeine, apple stem cells, keratin, panthenol
Glowing customer review: "I tried this Shampoo alongside the Stem Cell Conditioner as I was experiencing a lot of hair shedding. I can confidently say that after using this my hair shedding has returned to a normal level and because of that my hair is looking so much fuller and thicker. I would highly recommend if you are experiencing similar issues."
For a high-street shampoo that punches above its weight, this formula is a standout for thinning hair. L'Oréal's Growth Booster Shampoo features Aminexil, an ingredient associated with reinforcing hair at the root and reducing hair fall caused by breakage. Niacinamide is also included in its ingredients list and helps strengthen and nourish the scalp, while ginger root extract supports resilience and vitality.
Lightweight yet fortifying, this shampoo is designed to make hair feel denser and more resistant to everyday damage – ideal if shedding has become part of your hair-wash routine.
Key ingredients that reduce hair loss: Aminexil, salicylic acid, niacinamide
Glowing customer review: "After initially being sceptical about this I decided to give it a try and was pleasantly surprised. The shampoo is good quality, rich lather and in conjunction with the conditioner and serum its definitely making a difference to my hair as I am seeing more new growth!"
As a beauty journalist, I speak to hair specialists on the reg for insights into the world of luxe locks, and one brand that is recommended to me time and time again for maximising hair health is Nioxin.
Developed specifically with thinning hair in mind, Nioxin's Anti-Hair Loss Shampoo focuses on strengthening hair from the root while maintaining a healthy scalp environment. Caffeine and niacinamide work together to stimulate and nourish the scalp, helping to improve hair anchoring, while lauric acid conditions and reinforces strands.
Key ingredients that reduce hair loss: Caffeine, niacinamide, lauric acid
Glowing customer review: "Brilliant! I use along side with the nioxin 4 and have seen dramtic results from my postpartum hair. You only need such a small amount too. I have thick, wavy shoulder blade length hair and all i need is grape size, if that. Lathers up so well Pricey. But for the quality and the small amount needed, its definitely worth it. Had this for for nearly 2 months now i think and i wash my hair every other day and the bottle hasn't touch half way yet. Will be buying again."
Backed by decades of trichological expertise, Philip Kingsley is a brand built on understanding hair at its root – literally! And this Density Thickening Shampoo is one of their best-sellers, focusing on strengthening existing strands to minimise hair loss caused by breakage.
Hydrolysed pea peptides help fortify the hair shaft and create a thicker, fuller appearance, while gentle exfoliating ingredients keep the scalp clear and balanced. Overall, it's an excellent choice for fine or thinning hair that needs extra support and resilience.
Key ingredients that reduce hair loss: Salicylic acid, hydrolysed pea peptides, polymers
Glowing customer review: "Bought both this and conditioner. I have hair loss and thinning due to menopause and have used lots of different products. I can honestly say that these products work. Does not weigh down your hair just makes it look thicker. Even the next day your hair has volume."
I first discovered BondiBoost's HG Shampoo and Conditioner via a hair growth discussion thread on Reddit, where many users were promoting it as one of the best. And looking at its ingredients list explains the hype.
If boosting density is your goal, this cult-favourite duo is packed with growth-supporting actives. Redensyl and procapil are designed to support follicle health and reduce shedding, while rosemary and peppermint help stimulate the scalp and improve circulation. And on the nourishing side of things, soothing botanicals like aloe vera keep irritation in check, creating a healthier environment for hair to thrive. The result? Stronger roots, reduced hair fall and fuller-looking lengths with consistent use.
Key ingredients that reduce hair loss: Rosemary oil, peppermint
Glowing customer review: "It really helped with preventing further hair loss and helped my hair grow so healthy. I lost some hair due to COVID in the fall of 2021, and Bondi Boost really helped restore my confidence when I tried it in 2022. It’s a shampoo and conditioner I can’t live without now."
