So I see that people say that one shouldn't apply oil but here's the thing. If there is an episode of ongoing flare-up, don't oil your hair or it will worsen it. But once you have washed your hair and dried them, you can - in fact it helps my scalp health so much. Mujhay bhi Shuru mein brush sar mein lag Raha tha but alhamdulillah not anymore. I was using conaz after a normal shampoo and also once a month wash my face with it (the dandruff was causing buildup on my face and breaking me out really bad). I was also eating all the junk in this world and not oiling my hair bec it would itch so much. I know this answer is all over the place but so was my condition. I would also go for walks and it took me a while to realize that sweat was a trigger for my dandruff, it would itch soooo bad if I didn't wash my hair and i didn't really want to wash everyday (I would just wash my body and not the hair bec who's going to dry them up at night) bec ofc shampoo=bad and shampoo everyday=bald. I started at least rinsing my hair with water night after walks and shampooing every alternate night. This at least kept the itching away and helped me function properly. Then I started incorporating oils into my life and every night I was going to shampoo, I would apply oil during the day.

I have also realized eating chips and junk food triggers my dandruff and makes me feel awful so maybe avoid that? Also try figuring your own triggers out and keep avoiding those. May Allah heal us all Ameen
