What causes a spot of missing hair on scalp?
Patient: My son has a small spot of missing hair on his scalp. It itches but nothing else seams to be of an issue. The spot has increased over the past 2 days. I thought it might be ring worm but its just a an area of missing hair no red spot no discoloration. What could this be? Doctor: HIWell come to HCMFungal infection is very likely and this can be best treated with "selenium shampoo" apply the shampoo on affected part leave it like that only for 30 minuets then wash out it, just do it once in day, new hair would be started growing, if this does not give any response then you need to see the Dermatologist, hope this information helps, take care.
