Onion juice can indeed be helpful for hair care, primarily due to its high sulfur content, which helps in promoting hair growth and strengthening hair. In the Siddha-Ayurvedic tradition, remedies that boost hair health are often geared towards balancing the Pitta dosha, which, when aggravated, can lead to hair fall. Onion juice could improve blood circulation to the scalp and, in turn, nourish hair follicles. The enhanced blood circulation is vital for proper nourishment and growth of hair.
To use onion juice, you can simply blend medium-sized onions and then strain the pulp to extract the juice. Apply this juice directly on your scalp using cotton or while gently massaging to increase absorption. Leave it on for about 30-45 minutes before washing it off with a mild shampoo. Doing this two to three times a week can be helpful. Start with a small patch test to ensure you’re not allergic to onion juice, as it could irritate sensitive skin.
Incorporating Ayurvedic principles—diet, lifestyle changes—alongside topical treatments can be more effective. Eating foods that pacify the Pitta dosha like cucumber, broccoli, and fresh fruits and maintaining healthy routines like good sleep and stress management can benefit hair health. Remember to seek professional medical advice if hair fall persists, as underlying health conditions may be contributing factors.
Long-term excessive use of onion juice might cause scalp irritation, so moderation is key. And yes, the onion smell can linger, but washing well with an aromatic, natural shampoo can help.
