I am not a person that likes to spend a ton of money on products unless I KNOW they are worth it. These products ARE worth it. I have a lot of hair and it is down to the middle of my back, but I do not need a lot of this product to clean and condition my hair. In fact, the sample bottles (which are "hotel size") lasted me for FOUR, yes, four wash and conditions. That in it self is amazing. I washed my hair with another brand this weekend and my hair was mad at me. It was not nearly as soft and there was no shine. Needless to say I am here to buy another set to have at my boyfriends house. The Protect and Detangle is also amazing, again, you do not need a lot to feel the difference. And the smell? Terrific! I am a migraine sufferer and smells really make me sick when the are too strong, these products do not. I am a lifer.
