Can this product work on Boxers gray hair on their face ?

Answer by Chewy • Jul 03, 2022
This can be used on a dog's face. Please make sure to cover eyes when spraying face.

Does this cover gray hairs on a dog with a black coat?

Answer by Chewy • Apr 19, 2021
Magic Black has been specially formulated to blacken and intensify black and to cover stains, discolorations and blemishes.

Will this affect their skin if used often and left on the coat for a while

Answer by Chewy • Jun 07, 2022
This is a mild and effective shampoo. Use as you would use any shampoo and as often as you would like. It will not affect the animal’s skin.

Is this permanent or does it come off after a few washes?

Answer by Chewy • Oct 06, 2025
This spray is a temporary one-day spray that can be washed out.

Absolutely Terrible

After seeing the review with the white standard poodle painted to look like a skeleton, I thought this would be perfect for covering my boy’s gray hair. After bathing

After seeing the review with the white standard poodle painted to look like a skeleton, I thought this would be perfect for covering my boy’s gray hair. After bathing and clipping him (A several hour task when you’re dealing with a standard), I shook the can, lightly misted it over the gray hairs, waited a few seconds, and brushed it out per the instructions. When I touched him, my hand came away black, so I brushed and combed him out several more times to no avail. It also left his normally silky coat with this horrible dry and clumpy consistency. What was supposed to be the finishing touch forced me to re-shampoo, dry, and repeat my whole grooming process. 0/5 I would never recommend this product to anyone.
