This natural trick would boost hair growth in 2 weeks

 

Could a simple, inexpensive ingredient help boost hair growth? A 2012 study suggests a possible answer: Topical application of raw onion juice may stimulate hair regrowth in people with alopecia areata, a form of localized, non-scarring hair loss.

Convincing clinical results

According to this study led by researcher Rahul Hazare , participants who applied onion juice twice a day for 2 months experienced significant hair regrowth. By 6 weeks, 86.9% of the treated group had hair regrowth, compared to only 13% in the water-treated control group (P < 0.0001). Regrowth could even appear as early as 2 weeks in some people, and was generally visible for the majority after 4 weeks.

A natural mechanism of action

The positive effects of onion juice are thought to be linked to the presence of sulfur compounds, such as quercetin, which are known to nourish hair follicles. In addition, it has antimicrobial properties that promote scalp health, as well as antioxidant and anti-inflammatory effects that may protect follicles from external aggressions.

How to apply onion juice

To prepare this home remedy:

• Peel and blend 1 or 2 onions until you obtain a purée
• Strain the juice through cheesecloth or fine cloth
• Apply it directly to the affected areas of the scalp using a cotton pad or your fingers, massaging gently for a few minutes
• Leave on for 30 minutes to 1 hour, then rinse thoroughly with a mild shampoo.

This application should be repeated twice a day, preferably morning and evening, for 6 weeks to observe the first results.

Limits not to be neglected

Despite encouraging results, this study remains limited: the sample was small, the trial was not replicated on a large scale, and focused only on alopecia areata. The effectiveness of onion juice for other types of hair loss, including androgenetic alopecia (or hereditary baldness), remains to be confirmed.

Onion juice isn't a miracle cure, but it does appear to offer a natural and accessible option for those suffering from hair loss. Further research is needed, but this avenue deserves consideration.
