What The Head dermatitis!!!!!

What The Head dermatitis!!!!!  Actually  I am the kind of people who is not much hair ( I think is Hereditary.  Because Our family is not the hairy type)  And I always colouring  my hair, so last year my hair started lose one's hair day by day.... The first I just thought this is a normal thing, because I know people normally lose 50-100 hairs a day.  But when I after came back HK I got a lot of wound on my head, and my head skin always get red.  In fact I don't know it, is my aunt told me.....then my mum bought some medicine shampoo and cream to me.  But it doesn't work....=0=||||  OMG   I don't wanna be a Bald head  ㅠ______ㅠ.   So Yesterday I visited the doctor, and he said I got the head dermatitis.     Then give me a lot of medicine and cream and shampoo.....I really hope they are work, I still wanna colouring my hair, and make a lot of style on it~~>< and my mum always intimidate me said "zulu will be a bald head in someday~~HAHAHAAA"
