I got the copola treatment done about 2 months ago but i have questions that are kinda random. When your hair stylist is applying the treatment to your hair what tool does she/he use and do they apply it at a fast or slow pace? Also is the treatment a brown, watery liquid?

My stylist uses the brush tool that stylist usually use to apply color to the hair. She brushes it on at such a fast pace that I feel like she isn't putting enough on the hair because she spills it on the floor! The treatment is a brown, watery liquid ( I think this is because she uses the one that smells like chocoate?).
