I'm not sure what type of infection on my scap is. I've consulted 2 doctors online on practo. First doc said that its scalp ringworm.i've used medicines  for a month.At first i felt that its gone.But no later it showed up and hair loss has also been increasedSecond one said that its sebborhei.c dermatitis. And i'm using medicines for it. But i can see no improvement. What should i do? And nothing is visible on the scalp but i can feel little bumps which seem be in lines or can be a ring. And i can feel the irritation and buring only if i rub them or if i sweat in sunlight
