If You Rub Your Head With Onions, Will Hair Grow? The Truth

If You Rub Your Head With Onions, Will Hair Grow? The Truth

There is a hair loss issue that has been making the rounds on social media lately.

The claim is that if you rub onion on your scalp, hair will grow.

Just hearing it sounds so far-fetched that you may wonder whether this could really be possible.

Since there are also actual research results, let’s fact-check it.

According to reports, a small 2002 study from a university in Iraq applied onion juice to alopecia areata and compared hair regrowth with a control group that applied tap water.

The onion juice group was very small, with 16 men and 7 women, and the average age was said to be 22.7.

In the onion juice group, hair regrowth reportedly began after 2 weeks, and by week 6, hair regrowth was observed in 20 patients.

This change was said to have appeared more in men than in women.

Looking only at these results, onion may seem helpful for patchy alopecia.

However, it is hard to conclude that it definitely works.

First, the study results are extremely small in scale, and related testimonials are only being produced in places such as India and Iraq, where natural remedies are emphasized.

The reason onion appears as though it might help hair growth is sulfur. Onions are rich in sulfur compounds.

Sulfur exists in amino acids, which are components of proteins, and sulfur-rich keratin is a substance needed for hair growth.

It is also reported that onions have an effect of promoting blood circulation, which may help blood supply to hair.

Sulfur may be helpful, but whether applying it can definitely be expected to produce hair-growth effects has not been accurately verified, so this can be viewed as a cautious research result.

If anyone reads this and thinks, ‘I should try this for my hair too!’ I recommend doing it just for fun, and for hair loss, it is better to get help from a hospital.
