I received the sample set as a gift. I was so impressed with the it, repurchased the full size products. Expensive, yeah, but I have spent tons on hair products that are just horrible. I have gray/blonde, high lighted, longer hair. I'm also over 60. in thirty days I noticed less frizz, more shine and my style lasts several days without much retouching. The hair oil for my hair ends is amazing with smoothing.

I have fine, somewhat wavy hair, medium density and high porosity. My hair would feel greasy by start of day 2. Does not lather well, would need to do 2-4 washes to get a suddsy result. Would not recommend.
