How Does Keratin Help Repair Damaged Hair?

4 Ways a Keratin Treatment Can Repair Damaged Hair

Even a refined hair care routine can benefit from a science-backed keratin hair treatment. As technology advances, upgrading your product lineup can provide significant improvements for hair health, especially when dealing with keratin damage.

Nexxus scientists use proteomics to identify the specific proteins hair loses from damage. Common sources include heat styling, chemical treatments, UV rays, and pollution. This is significant, as hair is composed of 90% protein. Integrating a weekly at-home keratin conditioning treatment can help repair this damage and restore hair's integrity, even if you love your current products.

Key Takeaways

• Visibly Heals Split Ends: Keratin treatments can temporarily seal the hair's cuticle, which helps mend the appearance of split ends and prevents further damage between cuts.
• Breaks the Color-Fade Cycle: A weekly protein mask reinforces the hair's protective barrier, locking in color pigment and moisture to prevent premature fading.
• Counteracts Dullness in Curls: Keratin smooths the cuticle of curly hair, allowing it to reflect light uniformly and restoring natural shine.
• Hydrates Damaged Hair: Repairing masks with protein replenish moisture and strength depleted by heat, sun, and chemical treatments, combating dryness.

1. A keratin treatment can visibly heal split ends

While cutting is the only permanent solution for split ends, a keratin protein treatment can offer a temporary fix between salon visits. It works by sealing damage in the hair's outer cuticle, which helps prevent splits from worsening. The Keraphix Damage Healing Treatment Masque uses keratin protein and black rice to coat the hair strand. This process restores the cuticle, leading to stronger, more flexible, and shinier hair in just 3-5 minutes.

2. A protein mask can break the color-fade cycle

Damaged hair has a compromised inner cortex, making it susceptible to protein and moisture loss that causes hair color to fade. Re-coloring faded hair can perpetuate a cycle of damage. A weekly protein treatment, such as the Keraphix Damage Healing Treatment Masque, reinforces the hair's protective layer. This helps lock in proteins, moisture, and color pigment, preventing future fading and breaking the damage cycle.

3. Keratin can counteract dullness in curls

The irregular structure of curly hair causes its protective cuticle to be raised, which diffuses light and can lead to a lack of shine. Damage from heat or chemical treatments exacerbates this issue. A keratin treatment helps by enveloping each strand with proteins that align and smooth the cuticle cells. This allows the hair surface to reflect light more uniformly, creating shine. For example, the Curl Define Strengthen and Moisturize Leave-In Conditioner uses a PROTEINFUSION blend with marula oil and silk protein, providing amino acids specific to the needs of curly hair for smoothing and hydration.

4. Keratin can hydrate damaged hair 

Frequent exposure to heat styling, sun, and chemical coloring can deplete the hair fiber of essential proteins and moisture, despite its natural protective layer. This leads to dry, damaged hair. A weekly hydrating and repairing mask can replenish lost moisture. For instance, the Humectress Ultimate Moisture Intensely Hydrating Masque, is infused with elastin protein and green caviar. It deeply penetrates hair strands to restore hydration, add strength, and improve gloss.

Restore Your Hair's Strength with Keratin

Whether you're dealing with split ends, color fade, or dullness, incorporating a keratin treatment into your hair care can make a noticeable difference. These protein-rich formulas work by repairing the hair structure, sealing the cuticle, and replenishing lost moisture. By regularly using a keratin-based mask or conditioner, you can restore your hair's natural strength, shine, and resilience, effectively combating the signs of damage.
