It may seem unusual to use onion water for hair growth, but it actually works. The process of growing hair requires patience and commitment. If your hair takes too long to grow, and you have to cut it to prevent damage, it can be challenging to resist the urge to give up.

Although it requires a lot of patience, growing hair does not need to be painfully slow. Using onion in your hair care routine may promote faster growth and volume. In fact, this readily available component is a genuinely effective treatment for hair thinning and loss, and it can be found in practically every kitchen.


Benefits of Onion Water for Hair

Nutrients that are excellent for you abound in onion water. However, it is crucial to remember that the benefits of applying onion water to hair are not fully grounded in research.

1) Dandruff Control

Many organic acids, including glutamic, oxalic, pyruvic, malic, tartaric, citric, and fumaric acids, are found in onions, and onion water's antibacterial and antifungal qualities can help eliminate dandruff.

Onions' anti-inflammatory properties help to soothe itchy scalps. Moreover, it enhances blood flow to the epidermis, which adds to the hydration of the scalp.

3) Nurture Dry Hair

Many micronutrients in onion juice fortify weak and brittle hair. It also has antioxidant and anti-inflammatory properties that aid in boosting blood flow to the hair roots.

4) Loaded With Sulfur Compounds

How to Make Onion Water for Hair?

The procedure is straightforward for people who want to experiment with using onion juice to enhance their hair health or encourage regrowth. The steps to making onion juice are as follows:

  • Take about four onions, peel them, and cut them into small pieces.
  • Squeeze the onion or use a juicer to get the juice out of it.
  • Another option is to mix the onion chunks into a paste in a blender. Put the paste in the cheesecloth and press the juice out completely.
  • Apply the juice to the hair roots or scalp.

A few drops of essential oil may also aid in reducing the juice's overpowering odor. Essential oils like rosemary, lavender, and peppermint can help mask the smell.
