Hair is an essential part of one’s appearance. Yet, having healthy, luscious locks is still a distant dream for many.
Hair loss is one of the most common hair problems in the world, and millions of people suffer from thinning hair and excessive hair fall. Inadequate nutrition, stress, and genetics may all play a role in this.
Fortunately, many natural remedies can help you regrow your hair fast and even prevent hair fall. Onions are one of the most common hair loss solutions used by many cultures for ages.
Does Ginger Promote Hair Growth?
No, ginger doesn’t promote hair growth, and there is no scientific study either supporting this claim.
In fact, studies have shown that 6-gingerol, the main active component in ginger, may stop or slow down hair growth and is consequently being tested for hair removal products. (1)(2) For this reason, dermatologists don’t advise using ginger on the scalp.
However, ginger does contain many antioxidant properties that can help increase zinc levels in the scalp to indirectly stimulate hair growth. (3) However, the negatives of this remedy outweigh its positives, so it’s best to steer clear of it.
Do Onions Help in Hair Growth?
Yes, onions are a well-known natural remedy for hair growth and thickness. Onions contain several antioxidant, anti-inflammatory, and antimicrobial properties that can greatly improve scalp health. They also contain high amounts of sulfur, which helps boost hair growth by stimulating the hair follicles.
Including onion juice in your hair care regimen can yield the following benefits:
Do Ginger and Onion Juice Have Side Effects When Applied on Hair?
Ginger may cause a few side effects, which include:
- Skin irritation and burning, especially when applied directly to the skin
- Dry, flaky skin
- Itching and redness
- Mouth irritation, stomach upset, burping, diarrhea, heart problems, etc., (5) when consumed excessively
Onion juice is generally safe for application on the scalp, but it contains heavy amounts of sulfur, which can be a little caustic when used in excessive amounts or too frequently.
Some people have reported experiencing the following side effects after using onion juice on the scalp:
- The pungent sulfur fumes can make the eyes sting or watery. (6)
- The harsh sulfur content can strip the moisture from the scalp and leave it dry, itchy, and irritated. (7)
- Constantly scratching the itchy scalp can weaken the hair roots and lead to hair fall.
- Concentrated amounts of sulfur can also trigger scalp inflammation, which damages the hair roots and hampers hair follicle activity, both of which contribute to hair fall.

Hair Products Containing Ginger
Products containing ginger extract include ginger supplements, ginger hair masks, ginger shampoo, ginger hair oil, cold-pressed ginger soap, and ginger serums, among others.
Why Are Companies Using Ginger in Their Hair Products?
Companies utilize extremely little amounts of ginger extract in their hair products, and other growth-promoting ingredients (such as biotin and zinc) are mixed in.
Thus, product labels usually do not indicate any benefit or risk of using ginger-infused hair products.
Studies have found ginger to adversely impact hair growth, which has led dermatologists to discourage the use of this ingredient on the scalp.
Onions, on the other hand, contain sulfur and antioxidants that can help increase hair thickness, strength, and length.
