All I can advise is a healthy diet. Foods such as eggs, fish, milk, nuts and pulses are meant to help hair growth. Is your hair thinning? Maybe you have an iron deficiency?
If you have a scalp condition try massaging coconut or castor oil on your scalp. This is also meant to stimulate hair growth.
What are the properties of your hair? Maybe it needs something that it's not getting.
This is my prayer. That I'll die living just as free as my hair.
