I had dyed my hair for 30 years and finally had enough of the grey stripe roots after a week or so. I let my hair go grey and I kept it short and I used whitening shampoo to help get rid of the left-over color (bought at Petco...the shampoo is cheaper there). So now I am completely natural and I even stopped shampooing my hair altogether. I use this stuff from a company called AsIAm and I use coconut co-wash...kinda a cleanser/conditioner all-in-one. I get a ton of compliments on my hair color and it's the best thing I've done in a long time. I couldn't be happier with this decision.
