Collagen Hair Treatment: The Magic Potion

Collagen, the natural protein found in our body, is like the superhero of skin elasticity and strength [1]. It’s the main fibrous protein in our connective tissues, made up of three polypeptide chains forming a helical structure.

Now, let’s get a bit technical here. The star protein, collagen, consists of arginine, proline, glycine, and hydroxyproline amino acids.

These are essential for strengthening bones, joints, and of course, keeping our skin and hair hydrated and supple.

Collagen domino words

When it comes to hair, collagen is often referred to as the ‘botox of hair’ – and I can vouch for that! It did wonders to my hair, making it smoother, softer, and adding a healthy bounce to it.

The Science Behind Collagen Treatment

Collagen Hair Treatment is like a specialized spa therapy for your hair, revitalizing weak and damaged hair by deeply penetrating the hair shaft, healing, and sealing the cuticle layer.

The best part? You don’t need to spend a fortune on salon visits; you can do it at home! All you need is an extra pair of hands and a good collagen hair mask.

Apply it like an ordinary hair mask, let it sit for a while, then wash it off. Easy peasy!

When applied to the scalp, collagen stimulates new cell production, leading to thicker, stronger hair [2].

This superhero protein works by promoting cell turnover, resulting in healthier, shinier hair. It’s like turning back the clock on your hair damage.

As a DIY enthusiast, I often whip up my collagen treatments at home. I’ve linked a helpful video here to guide you through the process. It’s fun, economical, and, most importantly, effective!

What Is Keratin Hair Treatment?

Keratin – a word that’s music to the ears of anyone who dreams of lustrous, healthy hair. As a fibrous structural protein found in hair, nails, and skin [3], Keratin is like that super-nutrient your hair craves to show off its best self.

Speaking from my personal experience, Keratin treatment was a game-changer in my hair care routine. And if you’re yearning for smoother, shinier, and straighter hair, this treatment is going to be your hair’s new best friend.

There are various types of keratin treatments, and each one involves the magic of applying keratin on hair follicles to boost hair health. It’s like a rejuvenating spa day for your hair!

Now, don’t be surprised when I tell you that these treatments involve a chemical smoothing process.

It usually contains formaldehyde, which, though it sounds a bit scary, is what helps combat frizz making hair straighter and more manageable [4].

It’s like having your personal hairstylist at work, 24/7, keeping your hair frizz-free and fabulous.

One of the best parts? The effects can last up to six months, provided you adhere to the proper post-care treatment. I remember how my hair felt amazing even months after the treatment – it was totally worth it!
