Does it get tiring not to be able to take proper care of your hair? It can be very saddening when anything in your hair care routine just doesn’t seem to work for you, even when it works for all of your friends or family.

Well, this can simply be because your hair is built differently from others.
If your hair does not respond to most hair treatments and products, you may have what experts call: low-porosity hair. This type of hair is unable to soak up water and hair products. Whatever hair treatments you put on low-porosity hair would merely just sit on top of the hair surface and not get absorbed deeply into the scalp.
You might be shocked to discover that onion juice could be the solution you’ve been looking for if you have low-porosity hair.
According to experts, onion juice is a well-known biological remedy that has been taken advantage of to enhance hair health. It is packed with amazing nutrients, such as important vitamins and minerals that are vital for hair growth and development.
Experts go on to explain that the best part about onion juice is that it is lightweight, making it readily absorbed by the strands, even in those 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.
Benefits of Onion Juice for Low-Porosity Hair
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.
