Onion Juice for Hair Growth?? (Guest Post)

So just like any naturalista, I found myself deep in the YouTube world, binge watching videos on natural hair growth. I stumbled upon a video about onion juice as a hair growth aid. The idea of putting onion juice and walking around sounded absurd to me especially thinking of how the smell of onion usually lingers on your fingers after chopping them. However, I was intrigued so continued to do further research. As if it were a sign, one of my favorite youtubers (GreenBeauty) uploaded a video on an update of an onion juice challenge she had started. Unlike the rest of the videos I had come across, her recipe incorporated garlic, cayenne pepper and an essential oil. Sieving through the comment sections, I learnt that the concoction didn’t actually smell as bad as one would imagine, given the method used.

So I decided to give it a go. I used the onion juice recipe on my hair once a week for a month. I added lemongrass as my essential oil of choice because I love how it smells. Others add lavender, citronella and so forth. The lemongrass was great for me because of its strong citrussy smell so it over powered any onion scent. However, it important to do a little research if you choose to add different essential oils together as they made react differently with the other ingredients.

Between the 2 methods to prepare the concoction (BLEND or BOIL), I picked the boil method. This was because I felt the pungent onion smell wouldn’t be as concentrated and also because boiling doesn’t destroy the nutrients and benefits in the onions – they are instead transferred into the water. I used a spray bottle applying the mixture from my roots to my ends. It is very important to make sure you wrap a towel around yourself as the application process can be messy because of how watery the mixture is and because of the Cayenne pepper. TRUST ME ON THIS!

Benefits of the onion juice mixture:

1. Helps with thinning edges

2. Helps with shedding

3. Effective growth aid


1. White onions are richer in flavonoids and sulfur than red onions.

2. Garlic has antibacterial and antifungal properties, lots of sulfur, zinc, copper and stimulates blood flow to the scalp thus promoting hair growth.

3.  Cayenne pepper also stimulates blood flow to the scalp therefore bringing nutirents that aid in growth


1 white onion

2 garlic cloves

1 tsp of cayenne pepper

1 and a half cup of water

3-5 drops of an essential oil

Instructions for the Boil method:

  1. Cut up onion and garlic and leave them for 5 mins so that antioxidants can be released naturally
  2.  Add 1 and half cups of water and heat
  3. Remove from heat once it starts to boil
  4. Sift the onion and garlic out or remove with a spoon.
  5. Leave to cool
  6. Add a teaspoon of cayenne pepper and 3 drops of an essential oil to combat the smell.
  7. Put the mixture in a spray bottle OR an application bottle
  8. Apply mixture on scalp and strands
  9. Massage scalp for 5 mins
  10. Put on a shower cap or plastic bag for 1/2 hours.
  11. Rinse thoroughly, shampoo and deep condition


I left the mixture on for an hour and washed it off with shampoo, then proceeded to do my weekly deep condition. Before washing off the onion juice, I did notice from the first application how soft my hair felt. My hair texture has changed over the years from 4Z (lol) to 4C. The onion juice made it feel even softer to the point where my fingers were gliding through effortlessly. Upon my second application, I observed that in terms of combating shedding, there wasn’t much of a difference. On the third week my hair was significantly softened, and I noticed my scalp was flaking a lot less than it had been the last couple of weeks. By the 4th week’s application, my hair wasn’t itching and there was barely any flaking or dandruff on my scalp apart from product build up. Additionally, my hair looks a lot shinier and healthier and my edges appear fuller since incorporating this into my hair regimen.

On the other hand, my hair shedding didn’t change as much as I hoped for and in terms of hair growth, I did not see a difference. I feel as though to observe that difference, I would need to stay consistent for about 3 months and keep applying this mixture to enjoy the true benefits. Though it’s nice to see results immediately, we should be patient and CONSISTENT when we use natural ingredients in our hair. You can’t apply something once and expect to see its effect right then and there. It’s just like any skin care product.

I intend on continuing with the onion juice to see if it will grow my bald patch and the back of my hair where I recently got an undercut. I hope for positive results! I do implore people to be more experimental and open to trying new things!
