Go pharmacy buy a Shampoo with ketoconazole 1% Apply twice weekly for up to 8 weeks with at least 3 days between each shampoo. Rarely Severe allergic reactions may occurred on first day use notice that if there is irritation wash immediately then stop using, but in my experience i hvn't see such thing. Otherthing Use may remove curl from wavy hair, cause hair discoloration, and changes in hair texture this things will go back normal when u stop using the shampoo.Avoid contact with eyes. The price is around 200 birr something,...if no improvement visit ur Dermatologist...
