Cool Water, UV Shields & Heat Rules for Dyed Hair
1) Cool water = less swell, less fade
Hot water swells the cuticle so dye slips out. Cleanse in lukewarm and end with a quick cool rinse to lay the cuticle flatter.

2) UV shield = sunscreen for hair
UV degrades color and dulls shine. Use a leave-in with UV/thermal support before sun, car rides, or patio lunches.

3) Heat rules that actually work
- Set tools to low–medium; fewer passes, slower strokes.
- Always mist leave-in before blow-dry; finish with a serum to smooth and reflect light.
4) Pairings that save color
- Sulfate-free cleanse + softening condition
- Daily shield (leave-in)
- Finisher (serum on ends/canopy)

- Rinse immediately; cleanse gently that night.
- Re-seal with serum.
