a) stop running your comb over and over again in your hair, as its going to make it look more flat and thin
b) stop using waxes and gels( incase if you are)
c) more soya in the house!( i dont know the science behind it, google it yourself)
d) keep it away from being exposed to the sun. its something like sunburn can cause hair follicles to switch to a shedding phase instead of growing phase!
