how to apply onion juice on hair - #41663
I am really struggling with my hair lately and need some advice! I kept hearing about the benefits of onion juice for hair growth, and honestly, I’m kinda curious. I have this problem where my hair feels really thin and it’s falling out more than usual. Like, I used to have a nice volume, but now, it’s just flat and lifeless. A friend mentioned that onion juice works wonders, but I’m totally clueless on how to apply onion juice on hair properly. I read some random stuff online, but there are like a million theories. Do I really need to mix it with something, or just put the juice straight on? Also, how long do I leave it in? I’m worried about the smell, too, ugh! If I do this, am I gonna have to walk around smelling like I just chopped a bunch of onions? And how often should I do it? I really don’t want to mess it up because at this point, I'd practically try anything to see some improvement! If anyone has tips on how to apply onion juice on hair without making it feel all gross or sticky, that would be super helpful! Seriously, just a simple step-by-step would mean a lot! Thanks!

Applying onion juice for hair care can indeed be beneficial for promoting hair growth and improving the health of your strands, but I get that the process can seem a bit daunting due to the strong smell and different methods folks suggest. Let’s simplify this:
Start by preparing fresh onion juice. Take 1-2 medium-sized onions, peel, and chop them into small pieces. Use a blender or food processor to blend the onions into a paste. Place the paste in a cheesecloth or fine sieve, squeezing it to extract the juice. You should end up with about a half cup of juice, depending on the size of the onions.
Before applying, you could dilute the juice with a little water if you’re concerned about sensitivity, or mix in a tablespoon of honey or yogurt for additional nourishment. Some folks prefer adding a few drops of essential oils like lavender or rosemary to help mitigate the strong onion smell.
Apply the juice directly onto your scalp with a cotton swab or your fingers, gently massaging to encourage absorption. Take your time to cover the areas where hair is thinning. To avoid the smell lingering, it’s a good idea to cover your hair with a shower cap or a towel. This also prevents the juice from dripping and aids in better penetration.
Leave the onion juice on your scalp for about 30 to 45 minutes. Doing this once or twice a week is generally safe and effective. Always shampoo and condition thoroughly afterward to ensure you wash out any residue, inspecting to remove the smell completely. A mild shampoo with a pleasant fragrance can also further minimize any lingering onion scent.
Maintain consistent application over several weeks. Hair treatments, especially those from natural sources, patience and regular use before noticing significant changes, so give it some time. However, if you experience irritation or an allergic reaction, discontinue use and consult with a healthcare practitioner, preferably one familiar with dermatological concerns or Ayurveda.
Be mindful of your overall hair health, including eating a well-balanced diet and avoiding harsh chemical treatments or excessive heat styling, to maximize the benefits of any topical remedy like onion juice.
