Tried a 15 minute processing time for a demi-permanent color and it came out way too dark
Honestly, I had a client with about 30% gray who wanted a subtle blend. The tube said 20 minutes, but I thought I could shave off 5 minutes since her hair was so fine. Ngl, it turned out almost two shades darker than the swatch, especially at the roots. I had to do a quick color remover to fix it, which added an extra hour to my day. Learned that fine hair can actually grab color faster, not slower. Has anyone else had a color process way quicker than expected on fine hair?
