Keokarpin hair oil is best it contains vitamin e oil which promotes hair growth, it has a very pleasant smell.i use onion juice for hair growth monthly thrice so all we know that onion has a very pungent smell after washing the hair with shampoo also its smell remains constant on scalp whenever hair get wet it smells a bit weird keokarpin oil kills this pungent smell and give good pleasant smell with smooth and shiny hair
I really recommend this product because it is very useful for me
Thank you
