As a bonus, you won’t find any synthetic colors and dyes in this formula. “It also removes environmental residues and excess sebum, which allows for thicker-looking hair to rise to the surface,” she says.
5. Olaplex No.4 Bond Maintenance Shampoo
Olaplex’s line of strengthening hair-care essentials has long been an Allure editor favorite. The brand’s No. 4 Bond Maintenance Shampoo has earned high praise from Annie Gonzalez, a board-certified dermatologist in Miami, for its protective qualities that come from ingredients like Olaplex’s signature bond-building molecule. You’ll also find a slew of moisturizing oils like avocado oil, camellia seed oil, and soybean oil to seal in hydration.
Gonzales adds that this strengthening shampoo really works to protect your locks from breakage. “The less hair breakage, the fuller and thicker your hair will be,” she says.
6. Jason Thin to Thick Extra Volume Shampoo
For a drugstore product that costs less than $10, Jason’s Thin to Thick Extra Volume Shampoo has plenty of benefits to its credit. Ingredients such as biotin and hydrolyzed wheat protein work to prevent breakage and improve elasticity, which can lead to thicker-feeling hair, while exfoliators like lactic acid and salicylic acid gently slough away dead skin on the scalp.
Soothing aloe also helps to ease any scalp irritation. As an added bonus, Gonzalez loves that this formula is free of phthalates, petrolatum, sulfates, and parabens.
7. Isdin Hair Density Shampoo
Mariwalla recommends Isdin’s Lambadapil Hair Loss Shampoo because of its nourishing formula, made of ingredients like zinc and biotin, which “really make the hair look and feel thicker and fuller.” You’ll also find ginseng, which promotes hair growth, along with hydrolyzed wheat protein for strengthening hair inside and out.
8. Davines Volu Shampoo
Davines’ Volu Shampoo amps up hair volume, thanks to turnip root extract, which contains minerals like phosphorus, iron, and calcium that fortify hair. The shampoo also includes a trio of vitamins (A, B, and C) that boost scalp health. Just one wash with this shampoo leaves hair feeling soft and nourished — and smelling super fresh and clean.
9. Oribe Shampoo for Magnificent Volume
Not only is Oribe’s Shampoo for Magnificent Volume safe for color-treated hair, but it also smells amazing and noticeably enhances hair volume. It contains a polymer blend that coats each individual hair so that it looks and feels much thicker. The brand’s signature complex also works hard to protect hair from the sun’s rays and environmental damage from pollutants.
10. R+Co Dallas Biotin Thickening Shampoo
Bring on the biotin. In R+Co’s Dallas Biotin Thickening Shampoo, the strengthening ingredient coats each strand of hair so that it looks much more full. This formula hydrates and nourishes hair, thanks to antioxidant-rich moringa seed extract, as well as advanced polymers that help add even more body and bounce to your style.
11. Vegamor GRO Revitalizing Shampoo for Thinning Hair
If you didn’t guess from the name, this product is vegan. Vegamour’s GRO Revitalizing Shampoo for Thinning Hair contains B-silk, which restores and protects the hair from heat and environmental damage. Phytoactives in the formula also go to work to boost fuller hair and reduce the signs of hair shedding.
12. Verb Ghost Shampoo
Verb’s Ghost Shampoo coats the hair with quinoa protein to make it appear more full and shiny. It also boasts sunflower seed extract, which provides UV protection, as well as moisture-enhancing moringa seed oil.

It’s all about that texture. Sadick suggests OGX’s Thick & Full Biotin & Collagen, which aims to thicken strands with a blend of vitamin B7 (biotin), collagen, and hydrolyzed wheat protein.
15. Paul Mitchell Tea Tree Scalp Care Anti-Thinning Shampoo
Sadick likes this color-safe shampoo, which boasts a mixture of Kakadu plum, pea peptides, clover flower, turmeric, and ginseng. They work together to cleanse and strengthen the scalp for thicker hair down the road.
16. Nioxin Cleanser Shampoo
Nioxin’s Cleanser Shampoo is another Sadick pick. It contains amino acids, antioxidants, and peppermint oil to help increase volume and strengthen hair follicles without stripping natural oils from your hair.
17. Living Proof Full Shampoo
This Living Proof Full Shampoo is a past Best of Beauty winner and long-time Allure editor favorite. It helps strengthen your hair and add volume with the help of the brand’s patented, proprietary Healthy Hair Molecule, which, according to the brand, removes excess residue and buildup.
18. Laritelle Diamond Strong Shampoo
This Sadick-recommended splurge, Laritelle’s Diamond Strong Shampoo, is crafted from amazing ingredients that strengthen and provide moisture: organic argan oil, jojoba oil, rosemary, lemongrass, ginger, and cedarwood essential oil.
19. Dove DermaCare Scalp Pure Daily Care Anti-Dandruff Shampoo
Dove’s DermaCare Scalp Pure Daily Care Anti-Dandruff Shampoo contains 1 percent zinc pyrithione to gently fight dandruff without irritating the scalp. Plus, it smells like fresh, clean laundry — and the scent lasts, too.
