You have not referred to your age. You are worried about your hair thinning probably because it is premature. Also if it is in the family or hereditary it is highly likely that it is the cause for your hair thinning too. Also do you suffer from Seborrhea (dandruff), oily scalp etc. How is your diet? You do not suffer from anaemia? I am just trying to rule out the causes of hair fall before it is termed hereditary. If any of the above causes have been causing your hair fall, Homeopathic Medicine has good remedies like Kali sulf, Lycopodium, Pilocarpus, Phos, Natrum mur etc. to get rid of them and improve hair growth.
If genetics are the cause Homoeopathy can help in delaying the hair fall.
