What ingredients should I look for in a shampoo to keep my hair healthy?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Dandruff can contribute to hair loss by irritating the scalp and weakening hair follicles. To support healthier hair and reduce shedding, choose shampoos formulated with proven anti-dandruff ingredients like zinc pyrithione, ketoconazole, selenium sulfide, or salicylic acid. These actives target the yeast and inflammation behind flaking, calm the scalp, and create a healthier environment for hair to grow.

Still, dandruff-related hair loss can also signal other underlying issues—like seborrheic dermatitis, hormonal shifts, or nutrient deficiencies—that shampoo alone won't fix. Before guessing, take a free, instant, online symptom check to better understand what may be causing your symptoms and confidently plan your next steps.
