Hi ladies! I'm a new member to the site, but have been a lurker for a looooong time. : )
I started with Coppolla Keratin last March, and have had it done 4 times since. The last time was this past week. I do it myself, although I initially had it done as part of a training video for the line to use in training stylists in Peru. Random.
Anyway, I am so careful with my care in terms of cleansing and conditioning - and at this point, I can tell you the longest 4 inches of my hair are still stick straight and do not frizz. I wash my hair about 3 times a week and only use two shampoos - L'Oreal EverPure Smoothing and "Shampoo One" (knock of of Wen) from Sally's for Color treated hair.
I do view this as a permanent state of my hair because I haven't used anything that would break it down. And that's where I'm at with it! I do makeup for a living, primarily for print and video - and find it impossible to look good on set when my Keratin wears off. I don't have the energy to make myself look pretty too, so think Keratin is my holy grail for looking put together... lol
