Color-Treated Hair: 6 Rules for Long-Lasting Color and Smoothness


Coloring your hair is one of the most powerful ways to refresh your look—but maintaining that fresh-from-the-salon glow? That’s where the real work begins. Whether you’re going platinum blonde, auburn red, or deep brunette, color-treated hair demands special care to stay vibrant, smooth, and healthy.

Here are 6 golden rules—backed by science and decades of salon experience—to help your color last longer and your hair feel soft, silky, and damage-free.


1. Wash Less, But Smarter

Why it matters:

Frequent washing strips away not only dirt and oil—but also pigment. The more often you shampoo, the faster your color fades.

What to do:

  • Limit washing to 2–3 times per week.
  • Use lukewarm to cool water, not hot.
  • Choose color-safe, sulfate-free shampoos to avoid harsh detergents.

Product Tips:

  • Pureology Hydrate Shampoo – sulfate-free, color-safe, and rich in antioxidants
  • Olaplex No.4 Bond Maintenance Shampoo – gentle on color, repairs damage

2. Deep Condition Weekly (At Least!)

Why it matters:

Coloring lifts the hair cuticle, making strands more porous, dry, and prone to frizz. Deep conditioning smooths the cuticle and locks in moisture and pigment.

What to do:

  • Use a hydrating mask 1–2 times per week.
  • Look for keratin, amino acids, shea butter, or coconut oil.
  • Apply from mid-length to ends, avoiding the scalp if prone to oil.

Expert Picks:

  • Moroccanoil Intense Hydrating Mask – argan oil for silky softness
  • Briogeo Don’t Despair, Repair! Mask – great for dry, color-treated hair

3. Protect from Heat Like You Protect from the Sun

Why it matters:

Heat styling (blow drying, curling, straightening) accelerates moisture loss and dulls your color faster than almost anything else.

What to do:

  • Always use a thermal heat protectant spray before styling.
  • Limit use of high heat (keep below 375°F / 190°C).
  • Air-dry when possible, or use a microfiber towel to speed up drying.

Best Heat Protectants:

  • Color Wow Dream Coat – protects and smooths for up to 3 shampoos
  • CHI 44 Iron Guard Thermal Protection Spray – lightweight, affordable

4. Be Sun & Pool Smart

Why it matters:

UV rays fade dye molecules, especially reds and pastels. Chlorine and salt water strip color and weaken hair bonds.

What to do:

  • Wear a hat or scarf during extended sun exposure.
  • Use UV-protectant sprays or leave-in conditioners with SPF.
  • Before swimming, wet hair with clean water and apply conditioner to create a barrier.

Pro Picks:

  • Aveda Sun Care Protective Hair Veil – shields from UV rays
  • Kérastase Soleil Crème UV – lightweight leave-in with sun protection

5. Avoid Harsh Ingredients That Strip Color

Why it matters:

Some common haircare ingredients are too aggressive for dyed strands and will cause premature fading and dryness.

Avoid:

  • Sulfates – harsh detergents that fade color
  • Alcohol denat or isopropyl alcohol – drying agents
  • Clarifying shampoos (unless needed before coloring again)

Instead, look for:

  • Sulfate-free formulas
  • Low pH products (they help close the cuticle and lock in color)

6. Refresh Your Color Between Appointments

Why it matters:

Even with the best care, color will fade over time. Refreshing tone and shine keeps hair looking vibrant without re-dyeing too soon.

What to do:

  • Use color-depositing conditioners or masks to enhance tone.
  • Try gloss treatments (at-home or in-salon) to restore shine and vibrancy.
  • Schedule root touch-ups only when needed—over-processing leads to breakage.

Top Products:

  • oVertone Coloring Conditioner – deposits pigment gently
  • dpHUE Gloss+ Color-Boosting Gloss – hydrates and revives color
  • Redken Shades EQ Gloss – pro-level toning treatment (salon-use)

Final Words of Expert Advice

Color-treated hair can look effortlessly glossy, healthy, and fresh—but it requires thoughtful care. The key is preservation, not overprocessing. With these 6 rules, you’re not just keeping your color longer—you’re keeping your hair stronger.

Remember: When in doubt, ask your colorist for personalized advice, and always do strand tests before using new products at home.
