Benefits of onion juice in your hair:
Onion is high in dietary sulfur, and when it is applied to the scalp, the sulfur helps hair to grow thicker and stronger.
It will also stimulate collagen production that helps hair and skin to grow.
Another benefit is that it will increase blood flow to the scalp and hair. The increased bloodflow will help carry nutrients to your hair and help it to grow better.
It is easy to make and apply. You could also mix coconut oil into the mix before applying it. Do it once or twice a week, and you will see results. Remember it will smell strong, but is very beneficial for hair growth! Enjoy!
