Patanjali amla hair oil is useless because it does not provides the benefits as it is made for. I am using it from 2 months but, I havent seen any type of improvements in my hair. It is said that the oil improves the the roots of the hair and strengthen the roots, prevent hair fall but, it is not just that effective.
Its fragrance is also not that nice to smell, it is a very sticky hair oil and you can to wash off your hair after 30 minutes.
I would not suggest this oil for the improvement of your hair, I think it will be better to consult to a doctor for your any kind of hair problems.
Thank You
