Salicylic acid shampoos can wreck curly hair if you use them too often

If your scalp is dealing with seb derm or scaling, a 3% salicylic acid shampoo every wash is probably overdoing it, especially on curly hair. Salicylic acid is great for breaking down buildup, but it also strips oil fast, and curls already struggle to hold moisture.

I usually tell people to treat medicated shampoo like a scalp treatment, not a daily cleanser. Use it once or twice a week and keep it mostly on the scalp for a few minutes before rinsing. On the other wash days, switch to something super mild and fragrance-free with softer surfactants. Vanicream shampoo and Seen fragrance-free are both solid if your skin reacts to everything.

The biggest mistake I see is people trying to “clean” the flakes harder when their scalp barrier is already irritated. That just creates more dryness, itching, and tight curls that feel like straw. A lightweight conditioner on the mids and ends before shampooing can also help protect curly hair from getting stripped.

Curly hair with seb derm is basically a balancing act between calming the scalp and not frying the hair texture. Curious what’s worked for other people because some scalps hate oils while others calm down once the hair is properly moisturized.
