I'm 39 and have had grey hairs for the last 15 years. I used box dyes for ages, then got allergic to PPD (in dark hair colour) so I've been using henna/indigo/cassia mixes the last six years to cover the white hairs. I'm now about 50% grey I think around the front of my head, less so around the back.
I'm finding it harder and harder to get a good colour from the henna mixes as I get more white hairs. I suit cool colours better and henna gives warm colours.
I'm thinking of just growing the colour out and stopping colouring, but not sure I'm ready to be too grey yet! I don't want to spend money on highlights etc and I hate going to the hairdresser.
I was wondering if it would work to use something like Castings in an ash blonde. As it doesn't have bleach it shouldn't affect my remaining brown hairs. Will it be able to give the white hairs a little bit of an ash blonde tone so they just look like ash blonde highlights? Has anyone tried this way to gradually ease into going grey?
Thank you!
