Using onion oil for hair can be quite beneficial, especially when dealing with issues like thinning, breakage, and wanting to boost hair’s thickness and shine. Onion oil is known for being rich in sulfur, which nourishes hair follicles, promotes growth, and minimizes breakage. When it comes to using it, there are a few pointers you might want to consider:
Applying onion oil: You can definitely apply it directly to your scalp. It’s effective when massaged gently because it stimulates blood circulation, which can promote hair growth. Do it for about 5-10 minutes; massaging can also help relieve any tension or stress in the area. Always focus on the scalp first as this is where hair growth needs more support. Applying once or twice a week is generally sufficient.
Mixing with other oils: Definitely. Mixing onion oil with other oils like coconut or olive oil can be helpful. It can balance the strong smell of onion oil and adds additional nutrients. It’s recommended to mix one part onion oil with two parts carrier oil (like coconut for its nourishing properties or olive for its hydrating benefits).
Regarding the smell: Yes, onion oil can have a strong scent. However, leaving it on for at least 30 minutes to 1 hour can maximize benefit before washing it out. Some people do leave it overnight for deeper nourishment but ensure it’s comfortable for your scalp.
For sensitive skin: Before full application, it’s wise to do a patch test, especially if your scalp is sensitive. Apply a small amount on a patch of your scalp to see if there is any irritation or redness after a few hours. If your skin reacts negatively, discontinuing its use would be best.
DIY vs pre-made: A DIY recipe can be quite effective, especially if you want to ensure it’s fresh and free of preservatives. Simply extract juice from onions, mix it with carrier oils, and apply. However, pre-made versions often have essential oils or fragrances included to minimize the oniony smell, which might be more convenient.
Addressing root causes through a Siddha-Ayurvedic lens can help too. Analyze if any diet or lifestyle aspects might be aggravating pitta or vata doshas, as imbalances could manifest through thinning hair or scalp conditions. Incorporating food rich in vitamins A and E, omega fatty acids, and maintaining a calm mind can aid alongside topical treatments.
