I had it done at a salon and actually I was asked by my stylist to do it at no cost as part of their marketing around the new sevice...basically I was a hair model for them. And they used Koppala.

Not sure about the flat iorn heat setting but I think it was fairly hot.

As for the thinning it is from the root. I so think the thinning may be from other factors but my texture is the thing that I have noticed changing so much since the treatment. My hair is just so dry and brittle now. It was never like this before.

Thanks for listening!
