Onion For Hair Loss

The versatile onion has the power to do much more than just add depth and flavor to your meal. In fact, applying onion juice, rich in sulfur, other vital minerals, and antioxidants is an effective remedy for those struggling with hair loss, especially due to alopecia areata, an autoimmune condition. To apply, massage your scalp with a mix of onion juice and honey. Wait for 30 mins, then rinse it out with a mild shampoo.

Most of us envy those with thick, luscious locks, especially when we are losing ours. If this has happened to you, you may find your savior in your kitchen itself – the humble onion. Just juice it and apply it juice to your scalp.

Before we tell you why you should use onion for hair growth, find out more about hair loss.

Hair Fall Is A Natural Phenomenon

On average, you lose 100 strands a day, but if they are not replaced quickly, you have a hair loss problem.

Hair growth happens in three phases: active, resting, and shedding. In the first phase, the hair actively takes up nutrients and the shaft grows in length. By the shedding phase, the hair has completed its life cycle and falls out.

On average, people lose about 100 hair strands a day. Since this is a continuous process, there are always other active hair strands ready to take their place.

But in the case of hair loss or “alopecia,” a majority of the hairs entering the shedding phase are not replaced as quickly or abundantly with new hair. The result – thinning hair, bald spots, and a visible scalp.

Hair Loss May Be Autoimmune Too

So far, science hasn’t found a cure for alopecia areata, the autoimmune condition where your body attacks your hair.

You may start noticing a receding hairline due to any of these: stress, hormonal imbalance, heredity, anemia, vitamin deficiency, or even autoimmune conditions.

Alopecia areata is an autoimmune condition in which your immune system treats hair as a foreign element and attacks its follicles (where hair grows). It can affect both men and women and cause hair to fall out in clumps. Medical science doesn’t yet have the exact reasons or a definitive cure.

Onion For Hair Growth

Onion is rich in anti-inflammatory compounds that help fight hair loss.

Whether hair loss is caused by infection, medication, or an immune system attack, onion may be able to help you out. With its curative and antibacterial properties, onion can cleanse and nourish the scalp and even stimulate new hair growth.1 Massaging it onto your scalp will also help blood circulation and keep the follicles healthy.

Onion Juice Promoted Hair Growth In Alopecia Areata Patients

After using onion juice twice daily for 4 to 6 weeks, about 90% of alopecia areata patients experienced new hair growth.

Inone experiment on patients with alopecia areata, onion juice was applied to the scalp and massaged into areas where hair growth was minimal. After following this method twice daily for 4 to 6 weeks, about 90% of the participants experienced new hair growth.2

The bountiful layers of the onion are rich in two beneficial chemical groups – the flavonoids and the alk(en)yl cysteine sulphoxides (ACSOs).

Onion Flavonoids Are Anti-Inflammatory

Apart from giving onions their color, these flavonoids have anti-inflammatory properties, which can help reduce hair loss.3

Sulfur Compounds In Onion Fight Infections

ACSOs also make onions rich in sulfur, which is both antibacterial and antifungal and can help combat scalp infections that cause hair loss.4

As sulfur helps develop collagen, which strengthens hair, it also helps regenerate hair follicles and stimulate hair growth.

The right amount of sulfur helps regenerate hair follicles and stimulate hair regrowth. This is because it helps develop the collagen responsible for hair strength. The magnesium, calcium, and potassium in onions also promote blood circulation and decrease inflammation.5

Quercetin In Onion Combats Hair Loss Due To Inflammation

Quercetin in onions treats alopecia areata and prevents it from recurring.

Quercetin, another compound found in onions, is a bioflavonoid with anti-inflammatory properties. It prevents hair loss due to an inflammatory response in the body, possibly caused by strong medication like antidepressants, chemotherapy, or an infection.

In animal studies, quercetin has been found to be effective not only in treating alopecia areata but also in preventing it from recurring.6

Garlic Helps Too

As part of the same plant family as onions, garlic is also effective in promoting hair growth for many of the same reasons. In one study, 95% of trial patients experienced hair growth after applying garlic gel to the scalp.7

Onion Is Safer Than Anti-Hair Loss Medicines

Onion juice is totally safe compared to steroidal medicines that can give you painful periods or even cause weight gain.

Another positive to using onion and garlic juice, as opposed to steroidal medication, is the negligible side effects. Steroids can cause adrenal resistance and dysmenorrhea or painful period in women.8

Prednisone, a commonly used steroid in the treatment of alopecia, can cause weight gain and severe mood swings, a heavy price to pay for a lustrous mane.9 Onion juice on the scalp, however, has shown no side effects.

So, why not give onion juice a try with this simple recipe.

How To Use Onion Juice For Hair Growth

  • Juice up 2 medium-sized onions.
  • Add 2 tbsps honey.
  • Mix the two, and make sure it isn’t a runny mixture.
  • Dip a cotton ball in it and apply on your scalp. Then massage gently.
  • Leave it on for half an hour.
  • Wash off with plain water or a mild shampoo.

Note: Onion juice doesn’t smell all that pleasant, so add a few drops of your favorite fragrant essential oil. You could also use peppermint oil. It has proven benefits in regenerating hair.
