<s>[INST] i am 21 years old, and for the past few months i've been loosing alot of hair and my skin is very dry on my face and scalp, i think its seborrhoeic dermatitis. i'm more concerned about the hair loss though, could it be a lack of iron, or over active tyroid? [/INST] Hello, yes, for a diffuse hair loss without a significant preceding history, u need a complete blood count and a thyroid profile done, if any abnormality appears on these, correction of those will rectify ur problem.For the dry skin, use a good soap like dermadew soap for bathing and apply a good moisturiser like efatop-PE lotion post bathing.Seborrheic dermatitis presents with itching and extensive flaking on the scalp, ears, nasolabial folds etc., if you have these problems, then consult a dermatologist for confirmation of diagnosis and appropriate management.ThanksTake care. </s>
