When considering which onion oil is best for your hair, especially given an oily scalp, it’s important to focus on a few key factors like the extraction method, the formulation with other herbs, and your dosha constitution. In Siddha-Ayurvedic tradition, the way an oil is prepared can indeed influence its efficacy. A cold-pressed extraction method tends to retain more of the nutrients and volatile compounds that could nourish hair fibers and the scalp. This may help in promoting hair growth, not just by nourishing the hair, but also by keeping the scalp healthier.
For dealing with an oily scalp, blend of onion oil with calming and absorbing herbs like Brahmi or Bhringraj might be useful. These can balance excessive Kapha (oily quality) on the scalp. Look for formulations that combine onion oil with ingredients known to regulate oil production, like lemon peel or neem.
Your best choice also depends on ensuring the oil doesn’t contain synthetic fragrances or undesired additives, which could trigger excess oil production. Given the intense odor you’ve already experienced, consider oils enriched with sandalwood or lavender, which have pleasant scents and cooling properties that can soothe an irritated scalp.
In terms of brands, while I can’t recommend specifics, I suggest checking for transparency about ingredients and methods used. Go for reputable brands known for natural formulations, avoiding components that simply cover up odors.
If your scalp is naturally oily yet prone to hair thinning, apply onion oil sparingly—no more than once or twice a week—and cleanse it thoroughly with a gentle Ayurvedic shampoo for best results. This approach lets the oils’ benfits be absorbed without aggravating oiliness.
Should your hair concern persist or worsen, it’s advisable to consult a professional trained in Siddha or Ayurvedic medicine who can evaluate your dosha balance and provide personalized recommendations.
