Great and thorough review RCC!! Yes you apparently love Keratin. This is funny too because last time I did my K-pak treatment was not good. It was still during our high dews but my hair was all freaked out for days. That was going 2wks between treatments. I do get protein from other sources though and I've had bad reactions to Keratin in the past. So, I won't be trying this conditioner
I don't necessarily think that you aren't Med Coarse because your hair likes Keratin. I use conditioners with mild proteins like Amino Acids and I use BRHG regularly. My hair is most definitely
without a doubt Coarse and I don't have issues.
