The Science of Hair Color: Why Hot Water is Your Color’s #1 Enemy

Why Hot Water Damages Color

When hair is exposed to hot water, the cuticle (the outer layer of the strand) opens up. While this can feel soft in the moment, it also releases color pigments more easily. Over time, this leads to faster fading, dullness, and dryness.

The Science of Pigment Loss

Professional color is deposited into the cortex of the hair, beneath the cuticle. When the cuticle is repeatedly opened with high heat or hot water, those pigments are washed out prematurely. This is why blondes turn brassy, brunettes lose richness, and reds fade the fastest.

Why Lukewarm Water Is Better

Lukewarm or cool water helps keep the cuticle sealed, locking in pigment while maintaining natural shine. This small change makes a noticeable difference in color longevity.

Additional Tips for Protecting Your Color

• Use Sulfate-Free Products: Gentle formulas preserve color.

• Wash Less Frequently: 2–3 times per week is ideal.

• Always Use Heat Protection: Blow dryers and irons also open the cuticle.

• Schedule Gloss or Toner Appointments: Keep tones fresh and vibrant between full services.
