Dandruff: Dermatologists explain which shampoos address it

Dermatologists say dandruff can come from multiple causes, including an overgrowth of Malassezia yeast, and advise choosing shampoos that target the specific type of dandruff and using them consistently.

Dandruff is a common scalp condition that can show as visible flakes and frequent itching. Dermatologists note it often results from a mix of factors rather than a single cause. An overgrowth of the yeast Malassezia is a frequent contributor, while dry skin, excess oil and product buildup can also play a role. Experts say matching a shampoo to the type of dandruff and using it consistently is important. What experts report: - Malassezia, a yeast that normally lives on the scalp, can multiply and lead to flaking, itching, and inflammation. - Dry skin, excess oil, product buildup, colder weather, stress and hormonal changes are listed as contributors to dandruff. - Several commonly available active ingredients are reported to calm dandruff and help restore scalp balance when used consistently. - The consulted dermatologists did not necessarily endorse specific brands, and not every product works for every person. Summary: Certain over-the-counter ingredients can calm dandruff when they address the underlying cause. Undetermined at this time.
