Query: Note: positive reviews are NOT for Shine Happy

I don't know why reviews for all Natural Instincts products are grouped together, but I wish I'd looked closely enough to see that the reviews for Shine Happy are overwhelmingly negative--separately, Shine Happy would probably get an average 1-1/2 star at best, and for good reason. Who wouldn't like their hair a little shinier, right? So wishful thinking and misplaced trust persuaded me to try this, even as I was thinking, "It contains peroxide. What does peroxide do? Lighten and damage hair." Well...yup. My hair was virgin and seldom even blow-dried so in great condition, medium/light brown with natural dark blond highlights. This lightened my hair half a shade (not what I was looking for, but at least it's not orange) but took all the shine away. In fact, because it's significantly duller now, any color lift is offset so my hair doesn't look blonder, just much unhealthier. Great. Fingers crossed that I won't have a root line. What a terrible product.
