Keratin For Hair: Benefits, Uses, and Treatment Types

Keratin protein is the fundamental building block of your hair, making up approximately 90% of the hair shaft. It is a protective structural protein that acts as both an internal structural spirit and an external protective shield.

When the outer layers of keratin become damaged due to heat styling, chemical dyes, or environmental pollutants, the hair becomes porous. This leads to frizz, breakage, and a dull appearance. A keratin treatment works by artificially "filling" these microscopic gaps in the hair cuticle, restoring strength and creating a smooth surface that reflects light.

Why is everyone talking about it? Here is why is keratin good for hair:

• Frizz Elimination:

It seals the hair cuticle, preventing moisture from the air from entering the shaft and causing "poofing."

• Enhanced Shine:

By smoothing the overlapping scales of the hair strand, light reflects more evenly, giving hair a glossy finish.

• Reduced Styling Time:

Keratin-treated hair dries significantly faster and requires minimal heat to look polished.

• Strength and Elasticity:

It reinforces the hair's natural structure, making it less prone to snapping during brushing.

A common question amongst those thinning is: is keratin treatment good for hair loss?

The short answer is: not directly. Keratin is a smoothing and strengthening treatment for the hair fiber, not a scalp treatment for regrowth. However, because it reduces breakage, your hair may appear thicker and fuller over time as you retain more length. It is important to note that some intensive salon treatments use high heat and chemicals that can stress the roots if not applied by a professional.

If you are looking for long-lasting results (up to 3–5 months), these are the common professional routes:

• Brazilian Blowout: A popular method that uses a liquid keratin layer to create a protective barrier around each strand.

• Cezanne: A formaldehyde-free alternative that delivers smoothing results without the harsh chemical smells.

• Keratin Express: A faster, lighter version of the treatment that lasts about 4–6 weeks—ideal for those testing the waters.

• Japzilian: A heavy-duty combination of Japanese straightening (permanent) and a Brazilian blowout.

You don't always need a salon appointment to reap the rewards of this protein. High-quality topical products can provide daily maintenance and repair.

• Keratin Hair Mask:

These intensive conditioners, such as the TRESemmé Keratin Smooth Deep Smoothing Mask, penetrate deep into the hair to provide a concentrated dose of protein and moisture.

• Keratin Oil for Hair:

Perfect for finishing a look, these oils seal the ends and provide an instant boost of silkiness.

• Daily Keratin Shampoos:

Using a system like TRESemmé Keratin Smooth Shampoo helps gently cleanse while replenishing protein levels.

Wondering what happens during those three hours in the chair? Here is the standard process:

1. Clarifying Wash: Hair is washed twice with a deep-cleansing shampoo to remove all residue and open the cuticles.

2. Application: The keratin solution is applied to damp hair in small sections, ensuring every strand is coated.

3. The Wait: The formula is left to saturate the hair for 20 to 30 minutes.

4. Blow-Dry: The stylist dries the hair thoroughly with the product still in it.

5. The Seal: A flat iron at a specific temperature is used to "cook" or seal the keratin into the hair shaft.

The "balanced truth" is that keratin is a tool—and like any tool, it depends on how it is used.

• The Good: It provides unparalleled manageability and can actually protect hair from mechanical damage (brushing and styling).

• The Caution: Over-treating hair with protein can make it brittle. Additionally, traditional treatments often contain formaldehyde or its derivatives, which require proper ventilation. Always consult a reputable stylist to ensure the formula matches your hair's integrity.

The first 72 hours after a salon treatment are critical. To protect your investment:

• Sulphate-Free is Key: Use a gentle cleanser like TRESemmé Keratin Smooth Shampoo, which is designed to be low-sulphate to avoid stripping the treatment.

• Condition Religiously: Follow up with TRESemmé Keratin Smooth Conditioner to keep the hair hydrated and the cuticle sealed.

• Avoid Moisture: For the first three days, keep hair bone-dry—no gym, no steam, no rain.

• Silk Pillowcases: Switch to silk or satin to reduce friction while you sleep.

If you aren't ready for a chemical treatment, consider these:

• Hair Botox: A deep-conditioning treatment that uses vitamins and antioxidants rather than strong proteins.

• Lamination: A surface-level treatment that provides temporary shine without changing the hair structure.

In short, keratin for hair is the ultimate solution for strength and shine. Whether through a professional keratin treatment or at-home care with the TRESemmé Keratin Smooth range, replenishing this keratin protein ensures frizz-free, manageable locks. Prioritise proper aftercare to enjoy long-lasting, salon-quality results every day.

A: It is usually recommended to wait at least two weeks after the treatment, as the chemicals may interfere with the colour's vibrancy.
