Hello, welcome to HCM Continues hairfall in a boy of your age most probably points towards androgenetic alopecia... It is a genetically determined multifactorial disorder characterized by the gradual conversion of thick terminal hairs to thin hairs and finally baldness... As male hormones play a major role in its onset,,i personally feel that you should tackle it both by lifestyle modification and medications... As per your query, I would like to talk about the natural health practices: Take a nutritious diet rich in proteins, vitamin and minerals... Give your hairs a good hair massage with tips of fingers with lukewarm coconut and olive oil,,this will increase the circulation to scalp and hence growth.. Include yoga/aerobics/meditation in your routine... Stay away from bad practices like smoking and alcohol...
