Onion Water & Hair Growth

Probably you didn't expect me to say that onion can be used for hair growth.

All of us know that onion is a great ingredient for many recipes – especially for salads.

Every salad fan knows what I'm talking about.

But how can you use onion, more specifically onion water, for hair?

It is hard to believe that onions can do any good to your hair, right?

Yet, the truth is that onions are full of benefits for your hair:

  • make your hair shiner

  • strengthen the hair
  • improve hair elasticity
  • boost overall hair and scalp health

The good news continues.

In fact, onion water can be used by everyone, no matter the hair and scalp type.

The only thing you need to be careful with is allergic reactions.

Like any other natural remedy, onion water can cause allergic reactions.

For this reason – avoid using onion water in the following cases:

  • you know you're allergic to onions
  • you experience symptoms such as redness, irritation, itching

However, do not worry! Not many people are allergic to onions.

So the risk to experience such side effects is pretty low!

Let me tell you a fun fact! For us, using onions for hair care might be a little bit strange.

However, this is not a new practice.

There are some cultures you have been using onion water for hair growth for decades.

So what do you think? Is onion water suitable for you?



Onion Water’s Top Hair Nutrients

As you guessed, onion water is so beneficial for your hair thanks to its nutrients.

Each of them helps your hair in its own way.

I'm sure you are eager to discover which are those nutrients, so let's get started:

  • sulfurous compounds
  • vitamins like A and C
  • flavonoids like quercetin [1]

Let me give you some more details about those.

As you can note, onion water contains sulfurous compounds.

In other words, it is rich in sulfur. How does this help you grow your hair?

Well, in fact, sulfur is an essential mineral for hair growth and for boosting the production of keratin.

Who did not hear of keratin and its effects on hair?

Moreover, sulfur is one of the nutrients that help you strengthen your hair.

However, vitamins A and C also bring their contributions to your hair health:

  • vitamin A helps you keep your scalp healthy
  • a healthy  scalp leads to a healthy and long hair
  • vitamin C is a powerful antioxidant [2]
  • so it protects your hair from everyday damage

Last, but not least, let's talk a little bit about quercitin.

As I mentioned already, quercitin is a flavonoid that has many benefits:

  • is a natural antioxidant [3]
  • has anti-inflammatory properties
  • is anti-bacterial
  • can inhibit PGD2 which impacts negatively your hair cycle

In other words, quercetin is a super nutrient for your hair.

Fortunately, onions and onion water are packed with flavonoids like quercetin.

So do you have enough reasons to use onion water for hair growth?

If your answer is yes – then let me tell you how to actually do that.



How To Use Onion Water For Hair

As you probably guessed already, onion water is used externally. 

That is in case you want to grow your hair.

For other purposes, like improving your immunity, you can also drink it.

Yet, in today's article, we will focus only on how to use onion water for hair growth.

Moreover, there are more recipes that you can try – including a hair mask that contains onion water. 

However, until then, let me give you some general instructions:

  1. Apply onion water to your scalp.
  2. Do that no more than once a week.
  3. Then wash your hair twice to get rid of the smell.
  4. And you are ready to go!

Talking about the smell, this can be an issue.

That especially because it can be challenging to get rid of it even after you wash your hair.

So what can you do then?

Well, some people say that the smell can be offset with lemon juice.

Thus, if your hair still has a bad smell after you wash, it you can try this lemon trick.

But here are some extra tricks that you can try:

  • use apple cider vinegar to rinse your hair
  • use a citrus-based shampoo
  • add a few drops of essential oil to your shampoo

So if you want to try onion water, do not worry about the smell.

Or if you still don't want to try onion water, you can buy a hair product that is based on onions.

If you still want to try onion water, then let me teach you how to make it!
