The One Shampoo You Should Switch To ASAP For Thinning Hair, According To A Dermatologist

TRY IT: Dove Dermacare Scalp Anti-Dandruff Shampoo ($19.99) 

How can a dandruff shampoo help improve thinning hair? New York City dermatologist Francesca Fusco says that untreated chronic dandruff is actually one of the leading causes of hair fall. 

"Many women with dandruff don’t use a dandruff shampoo regularly because they are concerned with the lack of cosmetic elegance and the concern that it won’t beautify their hair,” Fusco explains. “A dandruff shampoo and conditioner that contain ZP [zinc pyrithione] and ingredients that beautify the hair can be used every day, as they will control dandruff, reduce inflammation, and thereby diminish shedding.”

If dandruff isn't a problem for you, Sadick says it's best to opt for a shampoo that is fortified with amino acids and antioxidants to promote hair growth and circulation and leave the ones with “dyes and preservatives, like parabens and synthetic fragrances" behind. 

"Amino acids provide the building blocks to build new strands, while biotin, part of the B-vitamin complex, is required by hair to metabolize amino acids and can help strengthen hair,” Sadick says. “Antioxidants such as vitamin E and ginseng are beneficial to promote hair growth because they reduce free radicals from sun, stress, or overprocessing and have anti-inflammatory properties.”
