I like that my hair is very shiny and specially for dark hair it's perfect color,what I didn't like ,that the color not last longer

Very good

nice color

Great hair dye and hold color much better then box dyes. I have used GK Hair for years and will keep using it.

soo good news the color is actually blue, not dark blue or black. The final shade depends on how you mix the dye with the oxygen cream (developer). When you mix the dye with a 20 volume (6%) or 30 volume (9%) developer, using MORE developer than dye will make the color turn out lighter and brighter, BUT ☝️ if you use more dye and LESS developer the result will be darker and deeper. So basically, you control how light or dark the blue looks by adjusting the ratio: -More developer = lighter blue -More dye = darker blue I’ve personally made this mistake so many times and especially after bleaching my hair twice just for it to turn black. I was so furious. اهم حاجة تتحكموا بكمية كريم الاوكسجين (يبقي اكتر) و كريم الصبغة
