I have my hair high and lowlighted every 6 or 7 weeks. But I think I must have very porous hair - my lowlights turn a light honey colour within 3 weeks (rather than the chocolate they are sposed to be!) She does try and do dark over dark and light over light each time (obv. not 100% - but near enough)
I get the majirel colours put in - are there any others out there that have more grab on your hair?
