I get my dark hair coloured to match my natural colour to cover the greys that are starting to come in. Normally the stylist puts the colour on the roots then combs it through to the ends for the last 10 mins or so.
It seems to need done more and more frequently - more often than it needs cut - and I'm wondering if it would muck things up if I used one of the root touch up products that are available?
Anyone got any advice or recommendations?
