Onions are of three types white, yellow and red. All of them are high in vitamins, minerals, and antioxidants.

Onions are rich in vitamin C, Vitamin B6, and manganese. Also, they have a small proportion of calcium, iron, sulfur, magnesium, phosphorus, potassium, and folate.

Vitamin C helps maintain collagen, the building block of the skin and hair. On the other hand, sulfur helps in sebum production and blood circulation and fights against dandruff and dryness.

Folate helps in hair growth and prevents premature greying of hair.

Onion juice benefits for beard growth:

Applying onion juice might not fill the beard patch, but it can help you in several ways. Let us discuss the benefits of onion juice, which promotes beard growth:

onion juice benefits for beard

Prevent beard dandruff:

Beard dandruff is when you feel dryness and redness in your beard coming out with white flakes. 

It happens due to yeast growth on your beard. Yeast growth or Malassezia develops due to a humid environment in the skin or a lack of hygiene which makes your skin red and flaky.

Onion juice contains sulfur, which makes a hostile environment for bacteria and prevents dandruff.

Reverse beard greying:

Onion juice is a complete pack of vitamins, minerals, and antioxidants required for healthy, shiny beards. 

Onion juice contains folate or folic acid that helps reduce premature greying of hair and maintains its natural color.

Fight against dryness:

The prolonged use of chemical-based products, polluted environment, heating tools, and improper diet are some reasons behind dry beards. 

You even suffer breakage, split ends, and whatnot.

Again, onion juice has sulfur which maintains sebum production. Sebum is a natural oil that moisturizes the beard and skin underneath.

Also, it prevents dryness, split ends, and breakage.

Improve blood circulation:

Any body part, including hair growth, needs proper blood circulation.

Massaging onion oil on the beard and the skin helps to improve blood circulation in that area and promotes better beard growth.

Add shine to the beard:

Excessive use of the chemical-based product, sun exposure, and improper diet ruin the shine and texture of the beard. 

Onion juice or onion oil for beard growth can help to maintain the skin’s PH level. The proper PH level helps rejuvenate new hair follicles and promote beard growth in better quality.

Also, better beard texture means better shine to the beard.

Prevent beard loss:

Using onion oil for beard growth is a wise decision. It might not help you fill the patches, but it prevents further beard loss.

Beard loss can occur genetically, internally, or due to external factors.

If your ancestors do not have thick beard growth, there is a probability you will replicate the same.

Internally, you might be deficient in some vitamins and minerals or have low testosterone levels, which impact your beard health.

Externally, sun exposure, wrong beard care product usage, habits, and diet impact your beard health.

If your problems are external or internal, onion oil for beard growth can help you. Sulfur and vitamin C improves collagen production, which is associated with healthy beard growth.

Improve skin underneath:

Onion juice or onion beard growth oil helps to nourish skin deeply and works like a conditioner. It smoothens the hair and moisturizes the skin underneath.

It helps to maintain the skin’s PH and make it fertile to grow a thick beard. It prevents dryness and itching and makes it suitable for hair follicles.

Does onion juice help in beard growth?

It is difficult to say whether onion juice helps in beard growth because no study has proven the fact yet.

There are studies present that support using onion juice for hair regrowth. But the hair on the head and the face is different. You cannot use the same concentration of products on both. 

Facial skin is more sensitive than the scalp. It might affect you negatively. So what is the solution?

If you are not allergic to onions and bear the smell of them, you can try them. Make sure to use onion juice in diluted form even if you are not allergic. Do not rub the onion slice directly on the face.

Wait for two months after applying it alternatively. If you observe any beard regrowth, then continue the usage. If not, drop the idea.

Two to three months are enough to judge any product. 

It may not help you with extreme regrowth, but it will help you in many ways. It is rich in beard vitamins, minerals, and antioxidants. 

So even if you do not get to fill your beard, it will help you maintain your skin’s PH levels, eliminating dandruff and dryness, adding shine to the beard, and reducing premature greying.

According to medical news today, onion consumption can increase testosterone levels. 

Testosterone is a hormone responsible for beard growth. When testosterone levels are low, people suffer from thin and patchy beards, while when testosterone levels are high, the opposite is true.

Studies have shown how your beard growth depends on dihydrotestosterone (DHT) production.

So if you cannot bear the smell of onions on your face, consume them in your diet or try other natural remedies for beards. They will help you with beard growth.
