Is Keratin Safe for Colored Hair? Here’s What You Should Know
Expert Advice from Venelle Salon & Spa in Park Slope, Brooklyn
If you’ve colored or highlighted your hair and dream of smooth, shiny, frizz-free locks, you’ve probably wondered:
“Can I do a keratin treatment if my hair is colored?”
The short answer is yes — keratin is safe for color-treated hair, especially when performed by professional stylists using high-quality, formaldehyde-free products like GK Hair and ProAddiction, both offered at Venelle Salon & Spa in Park Slope, Brooklyn.
In fact, a keratin treatment can make colored hair look even healthier and shinier — as long as it’s done correctly and properly maintained.
Let’s break down everything you need to know.
💎 What Is a Keratin Treatment?
A keratin treatment is a professional smoothing service that infuses your hair with keratin, the same natural protein your strands are made of.
Over time, chemical coloring, bleaching, heat styling, and environmental factors strip your hair of keratin, leaving it frizzy, dry, and dull. A keratin treatment restores that lost protein, seals the cuticle, and transforms your hair into a smoother, shinier, and more manageable version of itself.
At Venelle Salon & Spa, we offer two advanced options:
-
GK Hair (Global Keratin) — a gentle, protein-based smoothing system that enhances shine and softness.
-
ProAddiction Smoothing Treatment — a formaldehyde-free, amino acid–based system that repairs and restructures damaged hair from within.
Both treatments are safe and effective for color-treated, highlighted, or bleached hair.
🎨 How Keratin Treatments Work on Colored Hair
Coloring opens the hair cuticle to deposit pigment, which can sometimes leave strands porous and fragile. Keratin treatments work by sealing the cuticle, locking in moisture and color, and leaving your hair glossy and smooth.
Here’s what happens when you get a keratin treatment after coloring:
-
Your color lasts longer — keratin locks pigment in, preventing fading.
-
Your hair becomes stronger — the protein rebuilds damaged areas from chemical processing.
-
You get incredible shine — the smooth cuticle reflects light beautifully.
-
Frizz and dryness disappear — your hair feels softer and looks healthier than before.
It’s like a top coat for your color — protecting it while giving you that fresh-from-the-salon glow.
⚡ ProAddiction vs. GK Keratin for Colored Hair
Both ProAddiction and GK Hair deliver outstanding results for color-treated hair, but they work a bit differently.
| GK Hair Keratin | ProAddiction | |
|---|---|---|
| Main Benefit | Smooths frizz, enhances shine | Repairs and rebuilds damaged hair |
| Formula Type | Keratin protein (Juvexin) | Amino acid and bond-building system |
| Formaldehyde-Free | Low-to-none | 100% formaldehyde-free |
| Best For | Slightly frizzy, wavy, or dry hair | Chemically treated, bleached, or very damaged hair |
| Longevity | 3–5 months | 4–6 months |
| Color Safe | Yes, protects and seals color | Yes, strengthens color-treated strands |
💡 Pro Tip: If your hair is heavily bleached or fragile, ProAddiction may be your best choice since it’s ultra-gentle, fully formaldehyde-free, and focuses on internal repair.
If your hair is color-treated but not overly damaged, GK Hair will give you a smooth, glossy finish that lasts for months.
💆♀️ When to Schedule Your Color and Keratin
Timing matters when you combine color and keratin treatments:
✅ Best Option: Color First, Keratin After
For the longest-lasting results, get your color done first, and then apply your keratin treatment a few days later. The keratin seals the color in, adds shine, and makes the pigment last longer.
If you do keratin first and color afterward, the color may not penetrate evenly — so it’s best to color before.
💡 At Venelle Salon & Spa, our stylists can create a custom schedule for you — often performing both services in the same visit safely when using the right products.

🧴 How to Maintain Your Color and Keratin
After your keratin treatment, the right products and habits help you keep your color fresh and your hair smooth for months.
✅ Use a sulfate-free, sodium chloride–free shampoo and conditioner (such as GK Hair Moisturizing Duo or ProAddiction Home Care).
✅ Avoid washing your hair for 48 hours after your keratin treatment.
✅ Limit heat styling and use a heat protectant spray.
✅ Deep condition once a week to keep your hair hydrated.
