We all enjoy a good DIY beauty session now and then, and during the pandemic, we were all trying out current tips, one of which was putting onion juice to your hair. There’s no disputing that many Indian-based DIY products are based on age-old Ayurvedic remedies, which include a plethora of beneficial benefits for your body. However, we conveniently forget that natural ingredients, too, can have negative consequences, especially if not used correctly. Onion juice, for that matter, is high in antioxidants, anti-inflammatories, and sulphur, all of which are beneficial to your hair. Surprisingly, this high sulphur level can also be highly unpleasant to your scalp!
Onion provides minerals that provide antioxidants and antibacterial activity on hair,” says Dr. Madhuri Agarwal, founder and MD of Yavana Aesthetics. There have been anecdotal reports of onion juice improving hair texture, hair loss, and dandruff, she explains.
According to Dr. Kavita Rohilla, a senior consultant for Trica Hair Clinic at Jean Claude Biguine India, onions’ high sulphur content makes them a hair care go-to. “Sulphur is a vital component of proteins like keratin, which are the building blocks of hair,” she explains. It is supposed to boost skin cell renewal and promote hair growth.” Both doctors, however, concur that none of the claims are scientifically supported, particularly when it comes to preventing hair loss. Dr. Rohila, on the other hand, claims that there have been a few studies that suggest improvement in cases of treating alopecia areata using onion juice.
No Cry, No Onion
Before you start chopping, slicing, and squeezing, keep in mind that this treatment comes with a warning. “When applied to the scalp, onion works as an irritant,” explains Dr. Agarwal. It can temporarily enhance hair blood circulation, but it can also produce extreme burning, itching, or rashes after application, and can sometimes contribute to hair loss. Other issues, such as hair loss, dandruff, and hair thinning, should be checked and identified by a dermatologist
Dr. Rohilla continues, “If not thoroughly rinsed, it might cause irritation and hypersensitivity.” Excess onion juice absorbs natural moisture and oils from the scalp, causing dryness. Furthermore, because it has a terrible odour, people tend to shampoo more to eliminate it, which increases dryness.
Onion juice is not recommended for persons who have allergies, psoriasis, or dermatitis, and using it frequently can sensitise the scalp and worsen hair loss. A more comprehensive approach to hair and scalp care would produce greater results, including a well-balanced diet, adequate hydration and sleep, supplements, and a structured hair care programme tailored to your hair type. That is the best technique to keep your hair and scalp healthy.
