Onion juice and hair fall

This could damage hair, scalp and follicles. Continuous scratching on the scalp could cause weakened hair roots. It eventually leads to hair fall or inflamed hair roots.

Onion juice and an unpleasant odour

Another undesirable side effect of onion on hair is the unwanted odour that comes along with it. The collagen present in the onion causes this odour to stay behind even after the hair is washed thoroughly. Furthermore, if you try to wash off the smell with any chemical-based solid shampoo, it could lead to even more damage. One is advised to use freshly extracted onion juice to avoid the pungent odour of the juice.

Onion juice and a dry scalp
