The only thing that has helped me is washing my scalp frequently with products that ACTUALLY clean. The yeast feeds off of the oils on your scalp. I didn’t see a big difference until I switched shampoos.
Products with zinc pyrithione like Head and Shoulders didn’t seem to help me. I would use them daily and even leave them on for extended times like a scalp mask. I didn’t see any improvement until I started my wash and go journey. Finally, using a stronger clarifying shampoo began to help. That suave daily clarifier, Mielle Mongongo Oil Exfoliating Shampoo, V05 Kiwi and Dr Bronner’s did absolutely nothing for my scalp. I started to notice a difference when I began using Kinky Curly Come Clean and Biolage Normalizing Cleanreset.
I even had to change my moisturizing shampoos too. They weren’t strong enough to remove my sebum with regular use. I was using Mielle Pomegranate and Honey Shampoo and Design Essentials Almond & Avacado Shampoo. They did nothing for my scalp. Once I made the switch to moisturizing shampoos like Innersense Hydrating Cream Hairbath and Bread Hair Wash, I notice that my scalp was clean while being gentle on my hair.
I noticed the better my scalp was cleaned, the longer I could go between shampooing my scalp. However, once your flair up dies down, prevention is key. Don’t stop doing whatever you find helps.
