Classic Clean Anti-Dandruff Shampoo, 72-Hour Dandruff Protection, 1% Pyrithione Zinc, 28.2 fl oz

Head and Shoulders Classic Clean Anti-Dandruff Shampoo is the flagship of the H&S line and the clearest answer for everyday dandruff control. Classic Clean uses a zinc pyrithione formula engineered to cover more scalp surface than standard formulas, retained on the scalp after rinsing so the active keeps working between washes, no extended lather time needed. With regular use, it helps protect against visible flakes and leaves the scalp clean and healthy-feeling.

What is 1% pyrithione zinc and how does it help with everyday dandruff?

1% pyrithione zinc is an FDA-recognized over-the-counter anti-dandruff active that targets the Malassezia yeast responsible for dandruff at the scalp. Classic Clean is formulated for everyday recurring dandruff, gentle enough for daily use on all hair types including color-treated hair. With regular use, it provides up to 72-hour dandruff protection.

Are all zinc pyrithione anti-dandruff shampoos the same?

No. Not all zinc pyrithione formulas work the same way. Most anti-dandruff shampoos use a standard zinc pyrithione particle shape that provides uneven scalp coverage. Head and Shoulders uses a zinc pyrithione formula engineered with an optimized particle shape and size for better scalp surface coverage and retention after rinsing, so the active keeps working between washes, not just while you shower.

What is the difference between Head and Shoulders Classic Clean and Clinical Strength?

Classic Clean uses 1% pyrithione zinc for everyday recurring dandruff with daily use. Clinical Strength uses 1% selenium sulfide for stubborn dandruff when everyday care is not enough. It works faster on Malassezia when used as directed. Start with Classic Clean for routine control; step up to Clinical Strength when flares persist.
