I have somehow managed to get to my late thirties without ever dyeing my dark brown hair. Now I have enough grey hairs coming through to make pulling them out seem like a losing battle. I've been using Aveda colour deposit conditioner which helps but doesn't solve the problem (it's also a pain as it only lasts a couple of washes) and I think it's time to step it up a bit.
I'd go to a salon but I can't afford to keep up regular treatments so I'm thinking it might be better to start as I mean to go on, and do it at home. I understand that permanent colour is better for grey coverage but I don't want that as a) it's the first time I'm dying my hair and I'm afraid I'll mess it up and b) I'd prefer to avoid big root lines so something that washes out gradually is more appealing.
Any suggestions for semi-permanent colour that's effective at grey coverage on darkish brown hair? Or, even better, any natural alternatives (not henna) like vegetable dyes that actually work? Also, as a first time dyer are there any important tips that I should know? Thanks in advance...
