An amino acid treatment for natural hair strengthens the disulfide bonds, also known as cysteine bonds, that determine the curliness of your hair.

Think of curly hair as a springy scaffold. Unlike straight and Caucasian hair that doesn’t have any twists or bends along the lengths, curly, coily, and kinky hair textures can have many curl patterns.

Cysteine functions like permanent covalent bonds to keep your curls’ integrity. Without them, your hair would snap like dry spaghetti every time you tried to twist, curl, and bend them into different hairstyles.

But here’s the thing …

Over time, your hair’s cysteine bonds start to wear out, which can be due to aging, chemical treatments, or hair damage.

That’s where amino acid treatments come in handy to replenish and fortify these bonds so that they can hold your curl’s shapes tightly together.

In simple terms, they preserve your curl pattern to boost strength and length retention.

The Importance of Amino Acid For Hair

treatment amino acid and its benefits

Amino acids are the foundation for essential proteins that your curls need.

They work together to heal damage and replenish the hair’s inner structure. Commonly referred to as the “building blocks of protein,” aminos are used in almost every system of the human body.

When I first heard about an amino acid treatment on natural hair, I have to admit; I was a little confused because I thought it was only used for body-building supplements.

But then, it made sense.

Proteins are not only for muscles. They also build the tissue cells that give the hair shape and structure. And since curly hair has more intricate shapes, it’s fair to say; we curly gals need more of these vital proteins to support our hair.

So here’s how it all works …

The hair fiber consists of three layers:

  • Cuticle
  • Cortex
  • Medulla

Each of them relies on various proteins to function. Think of proteins as the life of your hair cells.

Now, you can’t just throw any protein at your hair and expect it to work.

When the human body consumes proteins, it has to synthesize them and break them down into smaller molecules that the cells can use.

These smaller molecules derived from larger protein blocks are what’s known as amino acids.

In short: Amino acids are ready-made synthesized proteins that your body can understand and use at various levels.

There are 18 types of amino acids derived from proteins, and the most important one for the hair is called cysteine, which works like the “cuticle-glue” to form cross-links with the inner protein cells inside the hair shaft.

Therefore, when the cysteine bonds are strong, your curls can stretch, bend, twist, swell, and shrink without snapping into pieces. Cysteine gives the hair elasticity.

To summarize all the sciency bits, amino acid treatments work like protein boosters to give you healthy hair with better manageability.

So let’s take a look at how you can use them to benefit your curly textured hair and what options are available.

Final Thoughts

The amino acid treatment for natural and curly hair is often overlooked in favor of pricier products like keratin treatments or relaxers.

But the truth is: Treatment like relaxers and formaldehyde-based keratin hair straightening treatments are often more damaging in the long term as they break down the cysteine bonds to rearrange curly hair into straights.

Remember: These cysteine bonds are the reason for your curl texture and pattern. If you damage them, the only way to restore your curls will be to chop them off and start growing them again.

So next time you’re looking for straightening treatments, look for cysteine treatments that use amino acids. It will be a win-win for your curls.
