Hi there...it is very difficult to treat if you just tell hair loss. There are many causes of hair loss like androgenetic alopecia, telogen effluvium, anagen effluvium, alopecia areata, psuedopelade of brocq, trichitillomania. You will have to be investigated for any associated comorbidities like thyroid disorders, anaemia, iron deficiency, other autoimmune diseases, drug intake. And based on the cause and type of alopecia you will be treated with minoxidil or tacrolimus or steroid or finestride. So kindly consult a dermatologist for further evaluation and treatment.
