Alopecia X
melatonin can help but i would be under the advice of a dermatologist. The skin so soft is good or coconut oil to keep skin moist and clothes are good too so skin does not get sunburned. My derm calls it tshirt therapy. My dd wears tshirts all the time to keep pollens off the skin and keep her from itching her self and damaging the skin
join this pom forum as they are probably very familiar with it and can make some suggestions
