My stylist, who I've faithfully followed for more than a decade, owns the salon and switched to the INOA system last year. I was unaware she had switched systems -- but I sure knew it after my color treatment. I have thin, fine, naturally curly hair. At first, almost immediately, it felt overly fine, thin and baby soft -- which is maybe nice if you have thick long hair. But for me, my style would no longer hold a shape. Even if I back-combed and sprayed, it would go instandly flat within an hour.  It was like "baby hair" and then I noticed that the color was fading and not covering my gray as well as the older product.  Within a month, my hair was dry and brittle. I complained a great deal. It was a struggle.. When my hair was ready for a new color, my stylist once again used the same product, despite my objection. The same thing happened again. Limp limp limp. soft at first ... then dry looking. I am "beside myself" with what to do.  I do not like INOA ... whatever it is.
