Highlighting/covering grey hair

Another option is L'Oreal ColorSpa. It's a semi-permanent that covers grey and looks very natural -- tone-on-tone. It fades gradually -- no obvious roots. It's also very gentle on your hair. You should be able to go about 28 shampoos before you need to re-apply.

If you decide to try it, make sure you do a test strand first. By choosing the right colour and getting the timing right, you should be able to match your natural colour.

Hello!

I would go visit a stylist for this one. Though your predicament is not all that difficult to fix, different types of grey hair (texture, shade, etc) accept color differently. A coloris will be able to find a color best suited to your hair type. Also, a stylist will know best how to blend the color for the best match.

If you can't afford an expensive place, try Costcutters (or any other chain salon) or a well- reputed beauty school in your area. If you ask for the salon manager, you'll get advice from a well-experienced colorist/stylist.

Best of Luck!
