So after the last hair cut it seems that I have 2 more inches of dyed hair left - so approx. 4 more months. Looking forward to that. Looking into conditioners for silver hair to bring out the shine and keep away any yellowing. I am using the following shampoo twice a month which is working really well - Klorane. And I am still doing the coconut oil treatment a few times a month as well. Can't believe that it has been a year since my last hair dye - it does go quickly looking back.
