I have water with a lot of iron that over time turns my blonde highlights to a shade of rust. I have tried other leave-in treatments that are supposed to neutralize the minerals, but they never got my blonde highlights back to the blonde they were supposed to be. I used the Hard Water Wellness Kit and it gave me my blonde back! I followed the directions on the Hard Water Wellness Remedy packet and left the product lathered in my hair under a shower cap and then wrapped with a towel for about 15 minutes then followed with the Hard Water Wellness Shampoo and Conditioner. My hair was softer and visibly lighter, back to the way it was when I was highlighted. I am a believer in this product to ditch the discoloration and get my blonde back. Thank you for offering a product for those of us with hard water! I am going to try the Color Prepare Wellness Remedy before my next highlight to cleanse my hair of the hard water minerals.
