I currently dye my greying brown hair myself (Majirel) but I've been wondering for a while whether I should go lighter in an effort to look younger/make the grey roots less noticeable. If I take the plunge, I'll want a really good colourist who knows what they're doing. My hair is quite dry and porous so a bad colourist could make it a lot worse.
Please let me know your recommendations for really skilled colour technicians in central, north, or east London. Thanks!
