I have just bought a Vidal Sassoon hair dye, got it home to apply it and the instructions are only for hair that needs to touch up roots and ends, so hair that is previously coloured. You need to put the dye on the roots for 30 mins then on the ends for 10 Mine isn't coloured and I want to do my full head, there is a little note on the instructions to look on their website if you haven't previously dyed your hair, but there is nothing on there. Nothing that I can see anyway.
How long would you leave it on for ? 10 mins as suggested for the lengths ? I don't want to leave it on for too long and for it to go wrong. I really can't afford to get it done professionally at the moment hence the home hair dye kit.
Is it the salonist stuff? The only thing I can see on the website is If you’ve never coloured your hair before, or if it’s been longer than 6 months, you will treat your roots and lengths the same way which suggests you just put it all over at the same time
Yes, that's the stuff. I thought that too, just wasn't too sure about how long to leave it on for. I might just wack it on and check to see if it has worked, then take it off. Thanks again for your help.
If you were doing it on previously coloured hair then the roots would have the colour on for 40 minutes anyway so I would leave it for that amount of time for a full head first colour. The dye will darken over time while its in your hair so don't be alarmed by it looking much darker than you expect.
Also, I have a designated 'hair dyeing top' that I use to save faffing about with a towel over my shoulders - means I don't mind if I get dye on it. Baby wipes are good for wiping away any dye around your hairline, on your ears, up your arms, etc!!
