Applying onion juice is a time-tested remedy in certain traditional practices, including Siddha-Ayurveda, known to potentially bolster hair growth by stimulating blood circulation to the follicles. Using onions, rich in sulfur, may strengthen hair, reduce breakage, and even improve thickness. To optimize the benefits of onion juice while minimizing discomfort and odor, here’s a more structured approach:
1. Preparation of Onion Juice: Blend two to three medium-sized onions and strain the liquid to obtain pure juice. To help with the smell and potential scalp irritation, mix in a small amount of aloe vera gel, rich in enzymes and nutrients beneficial for hair, with the juice. Just a tablespoon should be enough.
2. Application Method: Gently apply the juice mixture onto your scalp using a cotton ball or your fingertips, focusing on the areas where hair thinning is noticeable. Massage lightly for about 5 to 10 minutes to increase blood circulation, which can aid nutrient absorption.
3. Duration and Frequency: Let the mixture sit on your scalp for about 30 to 45 minutes. Longer application may cause irritation. Rinse it out using a mild, chemical-free shampoo to avoid negating its effects. Doing this remedy 2 times a week should suffice initially, adjusting based on how your scalp responds.
4. Post-Application Care: Consider washing out the onion juice with a diluted apple cider vinegar rinse (mix 1 part vinegar with 3 parts water) once a week. This can help with dandruff and reduce residual odor from onions.
For underlying causes, consider your dosha balance. Thinning hair might indicate a vata imbalance, often associated with dryness. Focus on a vata-pacifying diet, incorporating warming spices like ginger and sesame oil in your meals and scalp massage routines.
If irritation persists or hair thinning continues, it might be worth consulting a health professional to address nutrient deficiencies or other underlying conditions. While onion juice is a home remedy, ignoring persistent scalp issues for prolonged periods could delay necessary medical treatment.
