Because of my very long, thin and naturally graying locks, leave-in conditioners are a staple in my hair care routine. Gray hair tends to be drier and coarser than hair that has retained its natural pigment, so conditioning is key. I like that EVOLVh Leave-In Conditioner is also an "uber" detangler, because I lose a lot of strands combing through my wet hair - even more if my rinse-out conditioners don't contain de-tangling agents (and not all do). EVOLVh really does provide extra protection, and the protection lasts: my hair feels soft throughout the day and the day following - until my next hair wash.
It also smells amazing - a warm, sweet floral fragrance due to the potent blend of essential oils. I've purchased a couple of travel sized bottles, and they last a few months - so a full-size will last even longer. I strongly recommend using EVOLVh shampoo and conditioner, too!
