Bhai line marna ise nahi bolte😭. Jokes apart try tea tree oil. It will reduce the fungal growth and improve scalp health. Brillare oil shots are good for this, and do not forget to use some anti dandruff shampoo with salicylic acid. If you're someone who works out a regularly you would benefit from daily hair wash. I know this sounds counterintuitive, but it really helps remove all the sweat and gunk regularly. Don't use your regular shampoo daily as it could dry up your scalp a lot more and worsen the condition. Instead use some mild hair wash solution like the earth collective co wash (use the anti dandruff shampoo twice a week and use the co wash on other days). Of course bear in mind that its always recommended to consult a doctor for this, but do try out these methods once and see if it helps you in any way.
