Onion juice for baldness: does it work?

A 2014 study experimented with the effects of crude onion juice on several types of alopecia. This method got the best results on alopecia areata. However, this study did not provide enough proof to ensure onion juice was the cure for this type of baldness.

The most reasonable reason why onion juice works on alopecia areata is its high sulfur content. Sulfur nourishes the scalp and helps to grow luxuriant and healthy hair. Onion juice contains many nutrients the follicles needs. Those nutrients are excellent for growing thick and healthy hair, preventing breaking.

Onion juice: make it yourself!

The best way to get a nutrient-packed onion juice is to prepare it right before applying it to the scalp. Making onion juice a home remedy for hair is very easy. After peeling three or four good-sized onions, chop them into small pieces. There are two methods to extract the juice: squeezing them or blending them into a paste, then using a cheesecloth to extract the juice. Both ways are equally efficient to get the best quality onion juice for hair.

Use a cotton pad to apply the juice to the scalp. One of the downsides of onion juice is the smell; it is possible to add some drops of essential oil (rosemary, lavender, peppermint, almond, or coconut) to make the remedy smell better. Lemon juice is also an excellent option to eliminate the nasty onion smell.

Side effects

People allergic to onions should not use onion juice. Some non-allergic people experience itching, redness, and irritation after using onion juice for baldness on their scalp. The best way to ensure the absence of sensitivity to onion juice is to apply a small amount of juice inside the arm and wait a few minutes to see if a reaction occurs. If not, use the remedy as mentioned before.

While using the remedy, avoid any contact with the eyes. In case of accidental contact with the eyes, rinse with cold water.

There are no other significant side effects of onion juice.


The available documentation on onion juice’s effectiveness is inconsistent and is not formal scientific proof that onion juice cures baldness. However, some onion juice components can reinforce hair and prevent some problems.

Like other treatments, the results are not instant, and it needs a consistent use of onion juice on the scalp to see the benefits.
