what is a color seal for hair?

Question

Not shampoo or conditioner. This is an actual process like coloring your hair. Does anyone know what it is?

Answer 1

It's a salon treatment - some call it cellophane or glossifier. It coats the hair shaft to protect it and "seal" the color in.

Clairol makes a DYI product. (www.clairol.com)

There's some debate as to whether or not it is worth doing.
