Use Gradual Gray Shampoo like a regular shampoo until you see what you like (generally within 2-4 weeks), then use it a few times a week to keep the look you want. Leave the shampoo in your hair for 3 minutes while you shower. If for some reason, you want faster looking results, add shampoo to dry hair and leave on for 10-15 minutes.
How long does it take to see the results?
