There is often an awkward phase when growing out a hair colour. It takes four to five months to get a few inches of hair growth at the roots, but celebrity stylist Michael Douglas says: “It is the best way to grow the colour out, while regularly getting the ends of the coloured hair trimmed”. If you hate the roots, try a root powder instead of a spray; they last longer and aren’t as drying.
If – like Sarah Jessica Parker – you’d rather go down the colour route, Douglas suggests grey-blending: “Having thin, subtle highlights or balayage is a great way of blending your greys with your base colour, and some face-framing highlighted strands will brighten the face. After your hair has been bleached, you may find that your grey highlights start to look a little brassy, due to the toner being washed out, but using a purple toning shampoo can help.”
