Does Keratin Fade Hair Color? Here’s the Science (And the Solution)

Keratin treatments are praised for their smoothing, frizz-fighting, and shine-boosting effects. But if you've ever noticed your freshly dyed hair losing vibrancy after a keratin session — you're not imagining things.

Let’s dive into how keratin affects hair color, what causes fading, and how to choose a keratin formula that protects — not strips — your pigment.

Why Does Keratin Sometimes Fade Hair Color?

The goal of a keratin treatment is to deeply penetrate the hair shaft, fill in damaged areas, and lock the cuticle into a smoother, flatter position using heat.

But that process, especially when using harsh, high-pH, or formaldehyde-based formulas, can unintentionally:

• Open the cuticle too aggressively

• Push pigment molecules out of the hair

• Lighten or “mute” cooler tones like ash, silver, or pastel

• Cause warm undertones to become more visible

This is especially true for blondes, coppers, reds, and fashion shades, which are more fragile and fade-prone by nature.

🔬 What Makes Some Keratin Formulas Safer for Colored Hair?

Not all keratin treatments are created equal. If you want long-lasting color and smoothness, the formula matters.

Here’s what to look for:

• Formaldehyde-free or low-formaldehyde compositions

• Acidic pH levels (4.5–5.5) to avoid cuticle overexposure

• Amino acid-based smoothing rather than chemical restructuring

• Color-safe certifications or clear labeling for dyed hair

• Hydrating and nourishing ingredients like taninoplasty, argan oil, and vitamins

Nutree Amazonliss Tanino: Color Protection Meets Brazilian Smooth

If you’re searching for a keratin treatment that doesn’t fade color, Nutree Amazonliss Tanino is your go-to.

Why it stands out:

• Formaldehyde-free, taninoplasty-based formula
  Taninoplasty works by forming a protective biofilm around each strand — smoothing the hair without stripping pigment.

• pH-balanced for color-treated hair
  Its gentle acidity seals the cuticle and helps retain pigment molecules inside the cortex.

• Deep hydration + UV protection
  Prevents dryness and environmental damage that often leads to color fading.

• Salon-quality results at home
  Professional-level shine and softness, now available for personal use without compromising color integrity.

Real users report up to 3 months of smoothness and zero color loss — even on platinum blondes and vibrant reds.

Expert Tips to Maintain Color After Keratin

To maximize your results:

• Wait 3–5 days after coloring before applying any keratin treatment

• Use sulfate-free, color-safe shampoo and conditioner

• Avoid heat styling for 48 hours post-treatment

• Schedule your keratin every 10–12 weeks to avoid build-up
