Onion Juice for Low-Porosity Hair: 5 Benefits and Side Effects

Does being unable to properly care for your hair get tiring? Even if everything in your hair care regimen seems to work for all of your friends or family, it can be very depressing when it doesn’t seem to work for you.
Well, this might just be due to the unique structure of your hair.
You might have low-porosity hair if your hair does not respond to the majority of hair treatments and products. Water and hair products won’t hydrate this kind of hair. Any hair treatments applied to low-porosity hair would simply sit on top of the hair surface rather than being deeply absorbed into the scalp.
If you have low-porosity hair, you might be surprised to learn that onion juice might be the answer you’ve been looking for.
Experts claim that onion juice is a well-known biological remedy that has been used to improve the health of hair. It is incredibly nutrient-dense and contains essential vitamins and minerals for healthy hair growth.
The best thing about onion juice, according to experts, is that it is light and easily absorbed by the strands, even in people with low porosity hair.
NOTE: Hair porosity would hardly matter if you apply onion juice or any other remedy only to the scalp and not to the hair itself as the treatment will just be taken up by the hair roots. Moreover, remedies that have to be applied to the strands must work for low-porosity hair. Onion juice is one of them.
This article will present the advantages of onion juice for low-porosity hair and investigate the science behind its effectiveness.
Here are the hair benefits of onion juice, especially for low-porosity hair.

1. Promotes hair growth

Onion juice is packed with sulfur, (1) which is a mineral essential for hair growth.

A study showed that methylsulfonylmethane (MSM), which is an
organosulfur compound, can reinforce the disulfide bridges in keratin,
which is a protein that makes up hair.

Thus, it can be safe to say that onion juice may assist in enhancing hair growth and retaining healthy hair. (1)

2. Conditions the hair

Since onion juice is helpful in sustaining hair keratin because of
its high sulfur content, it can also help in conditioning your hair. (2)

Research suggests that keratin is efficacious in improving hair
strength. So, incorporating hair care products or remedies that enhance
keratin activity can also condition the hair and deliver healthy locks. (3)

3. Strengthens hair

Onion juice is also rich in vitamin C, (4) which is a powerful antioxidant that helps to protect the hair from damage. (5)

Research highlights the importance of antioxidants in promoting
healthy hair growth. The use of functional antioxidant agents can
improve the condition of the scalp, reduce hair shedding, and increase
hair fullness. (6)

4. Prevents dandruff

Onion has antifungal properties that make it an effective treatment for dandruff, which is a common problem that is caused by an overgrowth of fungi (yeast) on the scalp. (7)(8)

5. Reduces hair fall

Onion juice can also help to reduce hair fall. A study suggested that onion juice may be effective in fighting hair fall.

The study evaluated the effectiveness of topical crude onion juice
compared to tap water in the treatment of alopecia areata. The study
found that 87% of the patients treated with onion juice demonstrated
full hair regrowth compared to only 13% using tap water. (9)

Side Effects of Using Onion Juice on Hair

Onion juice is typically safe for topical use on the hair, and there
aren’t any notable documented adverse effects associated with it.

The most common drawback of this remedy, as noticed by researchers,
is simply the unpleasant odor of the onion juice, which can be fairly
strong and may linger on the hair even after rinsing it off. (9)

However, this odor can be decreased by putting in additional
ingredients to the onion juice, such as essential oils and lemon juice.

How to Use Onion Juice on Low-Porosity Hair?

Onion juice can be used directly on the hair and scalp, or it can be blended with other components to make a hair mask.

Here are a few methods to utilize onion juice to improve low-porosity hair:

• Combine 2-3 tbsp of onion juice with 1 tbsp of honey. You can also
  use 1 tbsp of coconut oil instead of honey. Apply the mix to the hair
  and scalp, let it sit on your hair for 30 minutes, and then wash it off
  with plain water.
• Mix 2-3 tbsp of onion juice with 1 egg. Apply the combination to the
  hair and scalp, leave it on for 20 minutes, and then wash it off.
• Store onion juice in a spray bottle, and spray your hair with onion juice whenever needed.
