I am a 23 years old girl who is having dry scalp. Its due to the dryness of scalp that I find it extremely tougher to even comb my hair. Sometime it satrts bleeding when I comb my hair and keeps itching throughout the day. I wish to know if environment affects scalp to go dry? What is the most favorable condition to keep scalp healthy? I also want to know about different Dry Scalp Treatment that is possible at home?
