I've been having regular highlights for a few years and my hair is breaking so I have been doing lots of deep conditioning and using less heat on my hair, I think I may be going through perimenopause and my b12 is low. I have some greys coming through so I'm looking advice if I should continue with highlights as I do want to eventually grow out my greys although this could still take a number of years or should I do an all over colour but I don't want to go to dark has anyone been in this situation thank you
