learn Ketoconazole

antifungal with some anti-androgenic benefits, often used as a shampoo

learn Procyanidin

Are Procyanidin based hair tonics or shampoos effective against androgenic alopecia? Procyanidin-based hair tonics may promote hair growth but lack definitive evidence for AGA.

learn Omega 3

Can a shampoo with omega-3s help thicken those early thinning spots? Shampoos with omega-3s may improve scalp health but won't thicken hair directly.

learn Trichogen

learn Redensyl

Are there shampoos with Redensyl that work the same as lotions? Shampoos with Redensyl are less effective than lotions for hair loss treatment.

learn Hair Fibers

Do hair fibers wash out easily, or do you need a special shampoo to remove them? There is no published trial comparing shampoos for removing hair fibers. Because the fibers cling by static rather than bonding chemically, and because users consistently report they rinse out with ordinary shampoo, the specialist fiber-removal shampoos do not appear to be necessary; a clarifying shampoo may help when fibers are layered under hairspray or gel.

learn Selenium

Is Selenium more effective when taken orally or applied topically in shampoos or serums? The two are not interchangeable and the evidence points the other way from the common assumption: topical selenium disulfide shampoo has clinical trial support for dandruff and seborrheic dermatitis, while oral selenium supplements have no reliable evidence for hair growth in people who are not deficient, and excess intake is a recognised cause of hair loss.
