What Happens Inside Your Hair During a Keratin Treatment?

Keratin treatments are more than just a salon trend—they're a scientifically formulated process designed to restore strength, shine, and smoothness to your hair from the inside out. If you've ever wondered what's actually going on during a keratin treatment, you're in the right place. Let's explore how this transformative treatment works at a microscopic level.

1. Understanding Keratin: The Building Block of Hair

Keratin is a fibrous protein that makes up approximately 88% of your hair’s structure. It forms protective layers around the cortex and cuticle, safeguarding your strands from breakage, frizz, and environmental damage. However, over time, keratin gets depleted due to heat styling, coloring, UV exposure, and pollution.

When hair loses keratin, it becomes porous, weak, and more prone to frizz and split ends. This is where a keratin treatment steps in.

2. How a Keratin Treatment Works on a Molecular Level

A professional keratin treatment infuses hydrolyzed keratin and other nourishing compounds deep into the hair shaft. This process involves several precise stages:

Step 1: Clarifying the Hair

The stylist begins by washing the hair with a clarifying shampoo to remove residues, oils, and product buildup. This opens the hair cuticles, preparing them to absorb the keratin formula more effectively.

Step 2: Application of the Keratin Formula

The keratin solution—often enriched with proteins, amino acids, and botanical ingredients—is applied section by section. The formula penetrates the hair shaft, binding with the natural keratin inside your strands. This helps rebuild damaged areas and fill in porosity gaps, making the hair stronger from within.

Step 3: Heat Activation & Sealing

Once applied, a flat iron heated to around 400°F (204°C) is used to seal the treatment into the hair. The heat realigns the hair’s structure while locking the keratin molecules into place. This process restructures the hair cuticle, creating a smooth, reflective surface and significantly reducing frizz.

3. Structural Transformation: What Actually Changes Inside the Hair?

The treatment temporarily alters the hair’s physical structure without breaking the disulfide bonds permanently (unlike relaxers or chemical straighteners). Instead, the keratin wraps around the hair shaft and forms a breathable, protective layer that enhances elasticity and shine.

Internally, the following changes occur:

• Porosity Reduction: Gaps and holes in the cuticle layer are filled with keratin, making the hair more resistant to humidity and water loss.
• Cuticle Alignment: Flattened cuticles reflect light better, giving hair a glossy appearance and smoother texture.
• Increased Elasticity: The protein reinforcement adds flexibility, reducing breakage and split ends.

4. Post-Treatment: Long-Term Hair Benefits

Keratin treatments can last between 3 to 5 months depending on your hair type, aftercare routine, and the quality of the product used. Regular use of keratin-safe shampoos and conditioners from Pure-Keratin.com helps maintain results longer.
