Alternative shiny hairs!

My boyfriend has been washing with longhairs [side note: he used another brand shampoo the other day and he said it burned!] The other day I noticed how the hair on his arms was reflecting different colors. I knew he had a few red whiskers, but now I can see those red hairs on his arms in the sunlight too! I liked watching the sparkles of different colors come off his forearms in the sun. The hair on my arms looks gold against my tanned skin. I don't have to buy body glitter - I have my own :-) (M USA)
