Prepare The Hair And Skin

Using onion water for the scalp can be an effective way to improve hair growth. Onion is rich in sulfur, which is necessary for producing collagen. Collagen is responsible for the elasticity of the skin, and it also plays a role in hair growth. In addition, onion juice can help to improve blood circulation to the scalp, which can also promote hair growth. 

Before applying onion juice to the scalp, preparing both the hair and the skin is essential. Onions contain a high amount of acidity, which can irritate the skin. To avoid this, it is vital to mix the onion juice with water or another liquid before applying it to the scalp. 

It is also important to shampoo and conditions the hair before applying onion juice, as this will help to protect the hair from damage. 

Prepare The Onion Juice For Hair Growth

There are several recipes for onion juice; however, although their recipes differ, the benefits of onions are mostly the same. Here are a few solutions for your hair that you can prepare in your home:

  • Cut a red onion in half. Rub the onion on the areas of hair loss for a minute, and then massage these spots for a minute. The best option for hair is to leave it like this overnight and wash off the onion juice with water.
  • Another option would be to take a couple of onions and put them in a blender. After using the blender, you should have onion puree. Then you should strain the onion juice through the cheesecloth. Then you need to apply onion juice on your head and let it soak in. Leave the onion juice on your head for at least 30 minutes. After that, you can wash your curls with shampoo.
  • If you want a solution for your hair and do not have a bad smell after use, you can combine onion juice with other oils. So, coconut oil, olive oil, and castor oil can be great options. However, in any case, after using a mix of onion juice and oils, you will still need to wash your hair with shampoo.

Apply The Onion To The Hair

The general recommendations for applying onion juice to hair are quite simple. You must have clean hair before the procedure, apply onion juice to the skin only if you do not have allergies and irritations, and keep onion juice on your head for at least 30 minutes. After the procedure, wash off the product with water or wash your hair with shampoo.

After The Procedure

After an onion hair treatment, you should pay attention to the condition of the hair and skin in the places where you applied the product. Pay attention to whether you have rashes, itching, or redness in places where onion juice is. You should stop using onion juice for hair if a negative effect appears.

If everything is right, you can continue applying the product to your hair and wait for a positive result. However, remember that using only onions is not a panacea; you should also take care of your hair and scalp regularly, apply oils and conditioners, and wash and dry your hair correctly.
