Does onion oil work for hair growth?

There is some evidence, though less than for rosemary. Onion is high in sulphur, which is a building block of keratin, the protein hair is made from. A small 2002 study on patchy hair loss found onion juice produced regrowth in most participants. That is one small study, so treat it as promising rather than proven. What onion oil reliably does is nourish the scalp, strengthen the root and reduce shedding.

Does onion hair oil smell of onions?

No. This is made with onion seed extract rather than raw onion juice, and blended with black seed oil and an essential oil blend. It washes out clean with a gentle shampoo.

How do I apply Onion Hair Oil for best results?

Massage a small amount into your scalp and hair from roots to tips. Leave on for at least 30 minutes or overnight, then wash with a gentle shampoo. Use 2–3 times a week.

Is Onion Hair Oil suitable for all hair types?

Yes. This lightweight formula works well for dry, damaged, curly, and normal hair types. If your scalp is oily, use a smaller amount to avoid excess residue.

Will Onion Hair Oil make my hair greasy?

No. When used in the right amount, this oil absorbs into the scalp and strands without leaving hair feeling heavy or greasy.

How soon will I see results with Onion Hair Oil?

Many users notice softer, smoother hair after a few uses. Visible reduction in hair fall and stronger hair tends to appear with consistent use over several weeks.

Customers praised this natural oil for reducing hair fall, promoting growth, and soothing scalps. Many noted "no strong onion smell" and lightweight texture. Shoppers reported visible results including thicker edges, reduced dandruff, and stronger hair. Some saw limited results for growth, though most recommend it as effective and worth the investment.

Good product👍👍

It’s early days i will let you know by the end of the month
Thank you

soothes my scalp. Love it, will buy again

Finally found something that does what it says. This onion oil actually helped with my itchy scalp, i'm off to buy the moisturising spray. great work guys

My dry scalp is gone, i no longer have flakes too. It really works.

Smells great, not what i expected, i have been using for a few weeks and i can see a great difference already. Worth it.

Love the scent, its lightweight and works so good. My hair has grown so much.

It’s an Amazing product

Excellent products, excellent customer service

I was having dandruff issue for a long time. Your onion oil helped in reducing the dandruff within the first week itself. Thanks. Overall great products

I can’t say I have noticed any hair growth or reduction in hair loss. The oil does have a lovely smell and makes my hair softer but I’ve had the same result with other hair oils. I was hoping this would work like it did for others but it simply didn’t work for me - maybe others will benefit from this product.

Finally found a product that actually works and is natural. Love it.

Really surprised by the results. This oil really works, my hair has been growing really well and my edges is thicker too. Thanks

This oil actually works! I've been using it about once a week for almost a year and my hair is so strong now (just on my second bottle now)
I have a heap of baby hairs growing in. My hair is thin and blonde so it damages easily and I can never seem to grow it long....until now! It's longer &stronger than ever! 💪

Was worried about the onion smell but it smells really good and its very light. It doesn't weigh my hair down at all. Hair definitely feels stronger and scalp is less flaky too

Was a bit apprehensive about the onion smell but to my surprise, it smells great. blends in well into my scalp, my hair shedding has reduced a lot, will be using this for a long time.

I have not used this item as yet

Smells nice, hair feels soft, easy to wash out. Don't know yet if it thickens hair but it's not hurting it.

This works!

Nice

I have been using this oil twice a week have noticed less hair fall so hopefully fingers crossed it is doing the job 🤞

It doesn't have a strong onion smell like most do. Washes out well. No idea if it works yet as I haven't used it long

Don't like the smell did nothing for my hair whatsoever

I ordered the onion hair oil for the first time and after using it for 2 months I can say that it really helped in reducing hair fall and strengthening my hairs.

Been using it for a month now and I liked the smell and it is not thick like other hair oils.

Replenhair's onion hair oil has worked some wonders on my scalp. I feel a difference in my hair texture. Can see more volume as well. Totally recommend if you’re concerned about the health of your hair.

I have been using the onion hair oil for 3 weeks prior to this I was using super seed hair regrowth both amazing oils, I have seen hair regrowth and less hair fall my over hair health has improved i oil my hair 3x a week and scalp massage 💆🏻‍♀️ also taking vitamins . Would recommend both hair oils my fave is super seed hair regrowth!!

This oil is amazing. I have been using it for a month and I can see the difference. I have lot more hair growing. Love it. I will definitely recommend this oil. 😀

I am beginning to see difference, but still early days. Impressed...

I love it. It's making my hair grow a lot

Got my edges back in less than a week. This is a miracle oil, I will surely buy again

I'm glad I ordered this. My hair fall has stopped now and I see new follicles coming out. Definitely worth spending your money on.

I'm liking the results so far. I can see new hair follicles coming out. This onion hair oil is definitely worth the money. Recommended!
