The six benefits of onion for hair that we did not know

Onion juice has been known as an effective remedy for numerous kinds of sickness, particularly for alopecia areata, which as an autoimmune kind of condition. If your hair loss happened because of a bacterial or fungal infection, as well as free radical damage, then the sulfur compounds and quercetin, which is an antioxidant that can be found in onion can actually help you. The sulfur has the ability to make your hair stronger. Onion can also spur the activity of your natural antioxidant against hydrogen peroxide that results to the graying of hair. Just simply apply the juice on your scalp directly.

If you are one of those people who are worrying about hair loss, we will be showing you two interesting titbits to lessen and finally get rid of your anxiety. Losing around a hundred strands of hair on a regular basis is natural, and rubbing an onion on your scalp has been considered as an amazing remedy for baldness in both England and Ireland.

The growth of human hair happens in 3 phases: active, resting and shredding. The hair shaft actively grows only in the first phase, and then it rests for a little while. Then, by the help of shredding, the hair falls out, which eventually completes its own life cycle. This is a continuous process, and other active hair strands take their place.

Onion has been known to be loaded with anti-inflammatory compounds that can actually help in fighting against loss of hair. However, in the cases of hair loss or alopecia, most of the hair that enters the shedding phase is not being replaced with new hair as it should be. As a result, people are suffering from thinning of hair, bald spots and even visible scalps. As a matter of fact, this situation usually occurs due to different kinds of factors such as heredity, stress, hormonal imbalance, anemia, vitamin deficiency, or even autoimmune condition just like alopecia areata, in which your immune system attacks the hair follicles or where your hair grows.

Unfortunately, medical science doesn’t have yet the exact reasons or a definitive cure to this kind of condition. Nonetheless, the humble and silently effective onion does. Furthermore, with the help of its curative and antibacterial properties, onion has the ability to cleanse and nourish the scalp and even encourage the new growth of hair. Massaging it onto your scalp will also help the circulation of the blood and even maintain the health of its follicles.

1. It promotes the growth of hair in Alopecia Areata Patients

After using onion juice for at least twice a day for about 4 to 6 weeks, almost 86.9% of alopecia areata patients in this study have experience new growth of hair.

In an experiment that has been conducted with alopecia areata patient, onion juice has been applied on their scalp and has been massaged on the areas where their hair grows minimally. After following this kind of method for around twice a day for about 4 to 6 weeks, the above-mentioned result happened. In fact, male patients have benefitted more than the women.

The plentiful layers of the onion are packed with two beneficial chemical groups which have been known as the flavonoids and the sulfur compounds such as alk(en)yl cysteine sulphoxides or ACSOs.

2. It can fight against Hair Loss because of inflammation 

Aside from giving onions their unique color, these flavonoids also contain anti-inflammatory properties. Inflammation in the body happens as a result of cell damage by reactive molecules that are known as free radicals. The flavonoids can also help in lessening the loss of hair by fighting against free radical damage.

Quercetin that can be found in onions can cure alopecia areata and even prevent it from happening all over again. It is higher in red onion, and it is loaded with bioflavonoid with anti-inflammatory properties. It has the ability to prevent hair loss due to an inflammatory response in the body, which are probably caused by strong medication such as antidepressant, chemotherapy or an infection.

In studies that was conducted in animals, quercetin has been found to be effective not only in treating alopecia areata but also in preventing it from happening once more.

3. It can help battle against Hair loss due to Infection

 Hair loss can also be a direct result of both bacterial and fungal infections in the scalp. ACSOs can also make onions rich in sulfur, which is known as both antibacterial and antifungal that can also help in fighting against the loss of hair. In addition, dandruff which can be caused by the said infection has been known as another reason for the loss of hair. Onion juice is a home remedy that can be used for dandruff, as well.

4. It make the hair stronger by enhancing hair protein

Onions contain sulfur that has the ability to help in developing keratin, which is the building block of the hair that eventually makes it stronger.

The right amount of sulfur can actually help in regenerating hair follicles and even stimulate the regrowth of hair. Keratin, which is the hair protein, is also made out of sulfur packed amino acid that is known as cysteine. The cysteine molecules connect with each other through strong disulfide bridges. This is what provides hair its additional strength. The sulfur compounds that can be found in onion can also provide this essential element of hair. The magnesium, calcium, and potassium in onions also improve the circulation of the blood and even lessen inflammation.

Moreover, onions are loaded with biotin or also called as Vitamin B7, which has been considered as the hair growth vitamin. On the other hand, the deficiency of this vitamin has been thought to be the reason behind having brittle hair, there is a very weak evidence that biotin itself assists in enhancing the growth of hair.

5. It helps lessen graying hair

Have you been informed about what most salons use in order to bleach your hair? It is hydrogen peroxide. Your body has the ability to produce hydrogen peroxide in a natural way, but when its levels go up, it builds up near the roots of your hair. As a result, this not only bleaches your hair, as we have thought of before, but it also harms your hair shaft through oxidative or free radical damage.

Catalase, glutathione peroxidase and even superoxide dismutase are enzymes that your body produces in order to break down the extra hydrogen peroxide. Onion has the ability to elevate the activity of all three in order to battle against hydrogen peroxide damage. As a result, it can be said to provide protection against the graying of the hair due to free radical damage.

6. It is a lot safer than anti-hair loss medicines

Onion juice is completely safe and effective when it is compared to some steroidal medicines that can actually give you painful periods or even cause weight gain.

Another positive effect of using onion and garlic juice, as opposed to steroidal medication, is the negligible side effects. Steroids have the ability to cause hormonal imbalance, as well as painful periods in most of women.

Prednisone, which has been known as a commonly used steroid in the treatment of alopecia, can actually result to weight gain and severe mood swings, a heavy price to pay for a lustrous mane. Onion juice on the scalp has not shown any kind of side effects, unless you are allergic to it. In order to make sure, do a skin patch first.
