I have hair loss issues from last 2 yrs. How do I tackle this problem with food? Please tell me what to eat and what should be avoided? I have been using onion juice pure aloevera gel together with amla, reetha and shikakai powder for ten days because I want to give it a try. I also feel itching in my scalp. I use camphor with oil for itching .i do not have any other health related problem. The other problem is I am very slim. I want to gain some wait. I am 30 years old and my wait is 50 kg. Is it ok ya I need to put on some wait because everybody used to tell me I am very slim.
