Yes hibiscus oil is good for hair growth as hibiscus oil is rich in Vitamin C, which stimulates collagen production.
The hibiscus oil is also very rich in amino acids which strengthen and nourish your hair so your hair will both grow better, longer and be much healthier.
Your hair will also be shinier as a result of using hibiscus oil on your hair.
I use hibiscus oil in my hair at least once per week to keep my hair healthy and shiny and it really does work.
You just need to keep up with the procedure of putting the hibiscus oil in your hair.
As long as you continue to do the hibiscus oil hair treatment at least once per week or once per month your hair should grow more and be much more healthy as well.
