Plus, collagen is a frequent ingredient in hair growth products. This is because it can improve hair in several ways. But what exactly does collagen do for the hair?

Let’s find out!

What Is Collagen?

Collagen is a type (see also: What Are The 5 Types Of Collagen? )of protein that is naturally created by the human body. It is the most prevalent protein in the bodies of mammals.

It’s found in multiple bodily structures, including:

  • Bones
  • Tendons
  • Skins
  • Blood vessels

What Does Collagen Do For Hair?

If you are using a hair growth serum, it’s important to consider the impact that it will have.

Here’s what it does for hair:

  1. It May Reduce Gray Hairs

Have you got some pesky gray hairs? As you age, it’s natural for hair to turn gray. This is because the pigment cells in the hair follicles start to die.

When it no longer contains melanin, hair will become clear. This results in it appearing gray or white.

However, collagen may be able to reverse the effects of gray hairs. This is because aging isn’t the only factor that can contribute to the death of melanin. Free radicals also cause graying.

Free radicals are a type of unstable atom that cause cell damage. These free radicals are caused by several factors, such as stress, pollution, and chemicals.

Because it contains antioxidants, collage might have the ability to accelerate graying hair. Antioxidants are compounds that can combat free radicals.

These antioxidants are often found in food, often in the form of vitamins C and E.

So if you want to slow down the graying process, it might be worth using collagen.

  1. It Could Stop Hair From Thinning 

As you get older, your hair will start to become thinner. Like the graying process, this is merely a normal part of aging.

The reason why collagen may prevent this hair-thinning process is that it is present in the dermis. The dermis is a layer of skin that is used to grow hair since the follicles are present here.

When you age, the body is less able to produce collagen to support the dermis. Eventually, many hair follicles will stop producing hair. This contributes to the hair losing its thickness.

By ensuring that your dermis receives sufficient collagen, you could prevent your hair from becoming thin. These building proteins could result in thick and healthy hair. 

  1. It Might Prevent Hair Breakage

Another reason why collagen is so prevalently found in hair treatments is that it could limit breakage. When we have less collagen in our body, hair is more likely to break.

This results not only in breakage but also split ends.

Collagen could enhance the strength of hair, thus reducing breakage. Moreover, collagen can add moisture to the hair. As a result, it’s a great cure for brittle and dry hair.

Should You Take Collagen?

Now that you know all about the potential benefits that collagen can offer for hair, you might be wondering whether you should utilize this protein.

Should You Take Collagen?

The truth is that research on the effects of collagen is quite limited.

Though this research has found that collagen can help both the skin and the hair, it’s still worth bearing in mind that these benefits are not guaranteed.

It’s also worth considering the fact that much of this research has been conducted by companies that manufacture collagen. You should question how reliable these findings truly are.

It likely won’t hurt you to take collagen capsules or supplements. Therefore, if you want to experience these potential benefits of collagen, it’s worth a shot.

Just don’t get your hopes up too high!

Different Types Of Collagen

If you want to use collagen to improve the quality of your hair, collagen can be taken in numerous forms. Namely, collagen hair treatments are typically sold in the form of powder,(see also: How To Take Collagen Powder) pills, gummies, and serums. 

To help you decide which form of collagen is best for you, we’ve explained each form:


This is a loose form of collagen. Collagen powder should be added to a drink to make it easy to consume. Alternatively, you can add collagen powder to your food.

It’s typically flavorless, so you won’t have to worry about it affecting the taste of your food or drink. Collagen powder is usually used for skin instead of hair.


Collagen pills, also known as tablets, can be swallowed like any other pills. They’re best taken with a drink of water.

This might not be the most pleasant way of taking collagen, but it’s fast and convenient.


Collagen gummies are commonly used for both healthy skin and hair. These gummies (see also: How Many Goli Ashwagandha Gummies Should I Take?)can be chewed and swallowed like candy.

They come in a variety of different flavors and can be quite tasty.


You should bear in mind that collagen serums are more commonly aimed at improving skin rather than enhancing your hair. This serum can be applied directly to clean skin.
