I am a firm believer in using quality products on your hair to maintain health and integrity.
I use Joico Vero K-Pak and Vero Chrome to reconstruct while it colors your hair. It looks shinier and healthier after you color than before.
For at home care, I recommend Enjoy Hair Care. It's PH of 4.5-5.5 insures your color stays in your hair and that it won't fade. It also has Cleanse Sensor Technology that insures your hair won't build up with product.
