Applying homemade red onion juice daily on the scalp can help in the regrowth of hair follicles.
Ayurveda also uses onions. In Ayurveda, it has been said that applying onion juice or paste directly on the scalp promotes hair growth and prevents dryness because of its Snigdha (oily) and Ropan (healing) properties.
In Ayurveda, onion is considered more of a medicine than a vegetable, as it says that onion works as a natural blood purifier.
