I underwent hair transplant in june 2019 and since then I have boils (funsi without pus) in my donor area. My transplant surgeon tried a few medicines on me like betadine, fucidin,clindamycin but none of them worked. Finally he suggested me to ignore it as it gets covered with a bit long hair (my normal hairstyle) and he said it will vanish with time. But 2 years have passed and still they haven't vanished. They feel very hard and turn red whenever I apply hair oil. Also they look bad when I keep my hair short. Please tell me the cause and cure for this. Thanks!
