<s>[INST] dear Doc,In the last four months i have lost a considerable amount of hair.And the loss of hair started after i got scalp psoriasis.Though the loss of hair in temple region looks like male pattern baldness,i doubt that the psoriasis is causing the hairloss because there is no hair thinning.Moreover when I was in Orissa in December there was no hairloss and psoriasis was almost completely gone.As soon as i came to Kanpur,I have started losing ahir again and the psoriasis has flared up [/INST] Hello,Welcome to healthcare magic.Psoriasis is usually not associated with hair loss.Sudden and severe hair loss all over the scalp could be due to illness, stress, crash dieting, medications which you have had had in the last 4-6 months. Localized hair loss confined to the front and sides of scalp indicate a male pattern hair loss.We have US FDA approved medications like minoxidil and finasteride for it but you need to take it for a long time as we cannot cure the genetic problem but can halt the process.You need to treat the psoriasis before starting on minoxidil as it can irritate the psoriatic skin. Use a tar shampoo 3 times a week. Use a lotion containing Calicipotriol at bedtime to keep the condition under check.These have to be prescribed by a dermatologist. Psoriasis and male pattern hair loss also requires regular follow up.Hope this helps you.Take care. </s>
