I'm 18 years old and I have been dealing with hair loss for last six months. It all started around January when my scalp became super itchy all the time. I noticed a huge amount of hair shedding. My hair has slowly gotten thinner and thinner all over. I went to the dermatologist at the end of April and he told me I had seborrheic dermatitis and prescribed me ketoconazole 2% shampoo, I used it twice a week for a month and it didn't seem to help and my hair continued to fall out. I went back to the dermatologist 2 weeks ago and he now says I am devolving scalp Psoriasis (which my mother has) and gave me T sal shampoo and talconex topical suspension and it doesn't seem to help at all. My hair is always shedding, every-time I run my hand through my hair i see at least 5 hairs come out. My hair has gotten so thin over the last month even the sides and back look thinner. It looks like diffuse thinning to me. Does anyone have any experience with this causing hair loss ? Do you think I am just diffuse thinning?
