The sulfur from onions may also help promote collagen production. Collagen in turn helps the production of healthy skin cells and hair growth.

Does Onions Work for Hair Loss?

here are many ways onion juice can help with hair loss. For one, onions are high in dietary sulfur, a nutritional element our bodies need.

Sulfur is found within amino acids, which are components of protein—especially keratin, which is known to be sulfur-rich. When added to the hair and scalp, onion juice can provide extra sulfur to support strong and thick hair, thus prevents hair loss and promotes hair growth.

The sulfur in onions may also promote collagen production. Collagen in turn helps the production of healthy skin cells and hair growth.

It’s also said that onions may boost blood circulation. Applying onion juice to the hair and scalp could increase blood supply to hair follicles, which in turn promotes hair growth.

Side effects:

Onion is a safe, natural, and affordable home remedy that can be great for your hair.

Even though the onions are not being eaten, contact with the skin can cause symptoms in people who are allergic. So test the onion juice on a small patch of skin before applying it to the scalp, to ensure that an allergic reaction does not occur.

Onion juice can also be irritating to the skin among people who are not allergic, causing redness and itching.

To do this, a person can apply a small amount of onion juice to the inner elbow or back of the ear and wait a few minutes. If irritation develops, it is best not to apply the juice to the scalp.

It is also important to avoid getting onion juice in the eyes. Onion juice that drips into the eyes can lead to burning and redness. If onion juice does get into the eyes, it is important to rinse it away with cool water.

Although it is not a harmful side effect, onion juice can have a very strong smell. The odor may dissuade some people from continuing with onion juice treatment, as it must be applied every day to have the best chance of being effective.


Using onion juice for hair is mostly safe. Many people have reported that it improves thickness, stimulates growth, and even regenerates new growth when dealing with hair loss.

Side effects also appear to be minimal. It is also fairly easy and not too costly to make an onion juice rinse for the hair.

Even among those who are not allergic, onions can be quite caustic to the skin.

Side effects may include redness and itching, depending on how potent a concoction you make. Mixing onion juice with an emollient like aloe vera or coconut oil may prevent this.

If you have an allergy to onions, you shouldn’t use onion juice on your hair.
