FOR PRO'S ONLY
I am not a professional but I colored my hair for over 45 years so I have some experience.  I let my hair grow out to a beautiful silver and should have left it alone!  The product turned my silver hair to a tannish grey.  Had to strip it and it is still a grey instead of silver.  If you aren't a pro don't touch this product unless you already hate your hair because you will hate it after you use this product.
