cosway gamat tonic is good

and i read that biotin is good for hair too.

also, avoid using too much chemicals in your shampoo and conditioner (try to avoid Sodium Laureth Sulfate).. so you try to look at organic type of shampoos (honestly, I feel it's very expensive and some of the midrange prices still had some chemicals that I wanted to avoid. However I might recommend Burt's Bees shampoo for their ingredients although I haven't tried it yet.. RM55/bottle)

you can use certain oils such as jojoba, coconut, or almond to promote hair growth.
heard that apple cider vinegar is good too, but for me it made my hair very kembang.
Also you should clarify your scalp (once in a while) with baking soda to get rid of all the silicone or other stuff that is stuck to your hair shaft.

l have had good results from coconut oil and gamat tonic, I did extensive research and experimenting with products and now my hair is OK, before this it was almost balding that I considered cropping my hair or getting a wig.
