Well, to be honest I’m also one of them. And to my surprise there’s actually one home-remedy which caught my attention and that is Onion Juice for hair. Sounds interesting right? So let’s dive deep into this topic and see if this remedy really works out !

Why Onion Juice for Hair Growth?
For decades to my knowledge, this onion juice treatment is a known remedy for hair health, specifically for hair-loss. It may help in restoring luster, shine and prevent hair thinning and dandruff.
As we all know, hair fall is a common problem that affects people of all ages. Onion juice is a natural remedy used for centuries to promote hair growth and reduce hair fall. There are some claimed benefits of onion juice for hair which includes alopecia, hair thinning, dandruff, scalp infection, etc.
The Science Behind Onion Juice and Hair Regrowth
According to science there are many ways that onion juice can help with hair loss. For one instance onions are high in sulfur which is a nutritional element which our body needs. Sulfur is found within amino acids and is responsible for production of keratin (protein) which is essential for hair growth. This sulfur is essential in promoting collagen (another protein) which helps the production of healthy skin cells for hair growth.
Another point is onions boost blood circulation, so when the juice is applied to the scalp it increases the blood supply to hair follicles which in turn improve hair growth.
Benefits of Onion Juice for Hair Health :
- Dietary sulfur : sulfur is one of the most common minerals found in the body. It is needed for the production of proteins, mainly keratin, which is essential for hair. When the onion juice is applied to the scalp it provides more sulfur to the hair that is more protein (keratin) which promotes strong and thick hair. The addition of sulfur to hair promotes the collagen production and blood circulation which leads to strong and healthy hair.
- Anti-microbial properties : onions have antibacterial properties which helps to fight scalp infections. One of the reasons for hair loss is scalp infection. So the more healthy the scalp is the stronger the hair follicles.
- Anti-oxidants : onions full of antioxidants such as flavonoids are believed to protect the body against free-radicals. These free radicals actually contribute to the aging process like hair thinning and hair loss. Canceling out these free radicals will reduce damage to the hair follicles.
- DHT reduction : Dihydrotestosterone (DHT) is a hormone mainly responsible for hair loss. Onion juice actually helps reduce DHT production in our body which in turn reduces its negative impact on hair follicles.
There’s also a small 2007 study published in the International Journal of Trichology that showed promise. For instance, researchers discovered that applying onion juice to the scalp helped people with alopecia areata, a condition that causes patchy hair loss, to regrow hair.
Furthermore in a recent article published by Healthline, the research highlights the potential benefits of using onion juice for hair growth, providing evidence that supports its efficacy based on the presence of sulfur compounds that may stimulate hair follicles.
My personal experience with onion juice (interesting)
To be honest, I’m willing to try anything with even a 1% chance of improving my hair. I love my hair the most, as I believe everyone does. When I first got to know about the idea of using onion juice for hair care, I was literally surprised by the positive testimonials online and it excited me a lot.
Now Let’s talk about some hard truths: from childhood, we’ve been taught by our elders to prioritize cost-effective solutions, at least in my family, especially when it comes to hair care. As a teenager struggling with studies and limited finances together, the idea of a natural, cost-free remedy like onion juice was incredibly appealing. With a constant fear of hair loss, I decided to give it a try.
Initially, I was surprised by the onion juice results which provided some relief for my itchy scalp (it cured my scalp infection). However, the issue resurfaced after a few days, teaching me the importance of consistency of using the onion juice alongside seeing the results. While I can’t provide any concrete evidence of hair regrowth, I hold onto the belief that it’s possible. I have faith that with continued use, new follicles will emerge. The power of positive thinking is undeniable, and in my experience, I’m pretty sure that consistent use of onion juice has helped reduce hair loss.
Based on my ‘onion juice for hair growth journey’, I encourage anyone who values their hair to give this hair mask a try. Meanwhile, one thing I can confidently affirm is that it hasn’t caused any harm to my hair.
DIY Onion Juice Hair Treatment: Step-by-Step Guide :
- Extraction : First blend or juice a raw onion, then strain the liquid to remove pulp.
- Scent : Next add 2-3 drops of Rosemary essential oil to the onion juice to avoid the pungent smell. Rosemary essential oil helps to promote hair growth. (some people might add lemon here as it even more solves dandruff issues, it’s totally up to you and find out what works for you in best case)
- Scalp Massage : Then apply the juice directly to your scalp and massage gently.
- Hair Treatment : You can leave the onion juice hair mask for 30-45 minutes.
- Washing : Wash your hair thoroughly with a clarifying sulfate free shampoo to remove the odor.
- Frequency : Use onion juice weekly once for optimal results.
Remember, consistency is key !
Potential Side Effects and Reality of raw onions :
The most common side effect will be skin irritation. People with sensitive skin must be very careful while using this home remedy because it may cause redness and itching. To do this people with sensitive skin should do a patch test before trying it on your scalp, apply a small amount of onion juice to the inner elbow or back of the ear and wait a few minutes. If irritation develops, it is best not to apply the juice to the scalp. And if you’re very much keen on trying it out, pls dilute the juice with coconut or castor oil and apply.
And one more thing is the strong smell of onions as it can stay with you for a while. So to overcome this, invest in odor-masking solutions like essential oils (like Rosemary essential oil which promotes hair growth and i personally use it) or strong-smelling sulfate-free shampoos.
What to Expect: Realistic Results with Onion Juice :
Onion juice offers a natural and affordable approach to hair growth. Many people have reported that it improves thickness, stimulates growth, and even regenerates new growth when dealing with hair loss.
One small study published in the Journal of Dermatology indicated that applying onion juice to the scalp might help hair regrow in some people.
Ultimately, the decision to use onion juice for hair growth is a personal one. However, for onion juice effectiveness – consistent use for weeks or months might be necessary. Just remember to dilute it, patch test, and be patient.
