Curry leaves are a rich source of beta-carotene and proteins,which can reduce hair loss and increase hair growth. They also contain amino acids and antioxidants which strengthen the hair follicles and moisturise the scalp. Curry leaves also help remove the dead hair follicles, which can be the reason behind dandruff.
To use, make a paste of curry leaves powder using a little water and strain out the juice. Add two tablespoon of yoghurt to make a hair mask and apply to the hair roots. Leave it on for 20 minutes and then wash with a mild shampoo. You could also make curry leaves oil (mix the powder with oil) and use it to massage your scalp.
