Past the one year mark now, but I'm still noticing thickening. So I can confirm that crowns do take longer, especially to mature. I am thrilled with the result. It looks totally natural and blends in brilliantly with my native hair, it is undetectable.
I took these pics outside in natural light, most in direct sunlight. There is no gel or wax in my hair.
