* Hair type: Fine or porous hair holds color less well, leading to faster fading. Coarse hair retains the dye better.
* Color intensity: Lighter shades fade faster than darker ones.
* Frequency of washing: Washing hair frequently strips color away more quickly.
* Water temperature: Hot water opens hair cuticles, allowing color to escape.
* Sun exposure: Sunlight can fade color over time.
* Hair care products: Harsh shampoos and conditioners can strip color.
Tips for extending the life of semi-permanent dye:
* Use cool water for washing.
* Choose color-safe shampoos and conditioners.
* Avoid heat styling, which can dry out hair and cause fading.
* Consider using a color-enhancing treatment or mask.
Remember, semi-permanent dye will gradually fade, so you'll need to reapply it to maintain the color.
