This is a very light serum, which conditions your hair with special spice and herb extracts including saffron, Sea Buckthorn, jojoba and vitamin E oils. It really helps with frizz reduction and shine, and left my hair super-silky, yet light. I’m a hair product junkie – no doubt about it, so this is a welcome guest to my bathroom cabinet and it smells incredible – no wonder all the celebrity hair stylists are going nuts over it for their Summer blowouts this year.
