STILL MY PERIODS ARE NOT REGULAR.my age is 29,   Wt.80 kgs. [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. If you have lost all your hair then it is important to rule out if you have something called Alopecia Totalis where one loses all the hair on the scalp. If not and you still have some good amount of hair you could consider PRP (platelet rejuvenation plasma) treatment where the plasma from your own blood is injected into your scalp with the help of tiny needles. This plasma is rich in growth factors and platelets which further help to strengthen the hair follicles and promote new growth. I also suggest a daily consumption of multivitamin which have biotin in them. Hope I have answered your query. Let me know if I can assist you further. </s>
