I have just dyed my husband's hair with Just for Men. Although I used a light colour it came out very dark. How can I lighten it up? Is it true that Vosene Shampoo gets too dark colour out?

Gray or light hair is more porous which can absorb hair dyes and make the shade appear darker. Vosene can be used to fade artificial hair color. If the Vosene doesn't help, opt for a dandruff or clarifying shampoo, these are known to strip hair color.
