From Kitchen to Scalp: The Hair-Growing Power of Onion Juice!

[BEAUTY] Onion juice might seem like a strange and pungent hair treatment, but it has been used for centuries as a natural remedy (popular in Aureyveda) to promote hair growth and improve scalp health! Onions are rich in sulfur, antioxidants, quercetin, and antimicrobial compounds that can help strengthen hair follicles, reduce dandruff, inflammation, and breakage, and stimulate dormant roots. Studies show that consistent use can result in visibly thicker, shinier hair within a few months.

Clinical trials have tested onion juice as a hair loss treatment. A 2002 double-masked trial published in the Journal of Dermatology, where the participants had alopecia areata and applied onion juice to the scalp twice per day for 8 weeks, observed visible scalp hair regrowth in about 87% of participants (significantly more than a control group that used only tap water). The authors of that study concluded that the hair regrowth effect was due to the high sulfur content of onion juice (high sulfur content can stimulate collagen and keratin production), as well as antimicrobial and antioxidant activity. Later clinical trials have tested a topical formulation of onion extract, along with other botanical ingredients (such as rosemary and caffeine), in the treatment of pattern hair loss. Results have been promising.

Yes, it can be smelly, but many find the benefits to be worth the temporary odor. A little onion juice today, fuller, healthier hair tomorrow!

To use 
Simply blend a fresh onion (any color) and extract the juice, then apply it directly to the scalp for 15–30 minutes (feel free to leave it on longer) before rinsing thoroughly with shampoo (2x). Repeat this process 2–3 times a week.
