How long does the color last?
The demi-permanent formula provides long-lasting color that gradually fades over time, typically lasting up to 6-8 weeks with regular washing.

Nathan Ferguson –
I’ve used this color on my medium brown hair and it gave a warm, natural look with great shine. My hair felt softer after each application and didn’t feel dry or brittle. The golden undertones added a nice depth without being too bold.
William Wright –
The color lasted about 7 weeks before fading noticeably. I liked the shine boost and how it didn’t make my hair feel stiff. It’s a good option for those who want a subtle, long-lasting change without harsh chemicals.
Andrea Glover –
I have previously used ammonia-based dyes and found this to be much gentler. My hair stayed hydrated and felt smoother after coloring. The 7B shade is perfect for warm brown tones and looks natural on my medium hair.
Virginia Gill –
The color is nice, but it faded faster than I expected. I think it might work better on hair that’s already in good condition. Still, the shine improvement is noticeable and the formula feels less harsh than other options.
