Hello,
Gaps commonly occur between hairs due to hair-fall. Hairfall may be related to genetic factors, mineral & vitamin deficiencies, dandruff, etc. You are suggested to keep your scalp clean, use Selsun shampoo regularly. After shampoo keep your hair and scalp oiled with almond or coconut oil (massage it with your finger tips gently).
Take
vitamin A, D & iron rich food or supplements to reduce
hair fall. Take biotin (vitamin B7), it is good for hair and skin. If the hair follicle is intact, new hairs will grow. You can use
Minoxidil (Rogaine), rub or spray it in your scalp twice daily.
Finasteride (Propecia) is a pill that you take once a day. You can also visit a
dermatologist or a surgeon to get hair transplants done.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
