Thanks for all of the responses. I'd appreciate hearing from anyone else who has experience (direct or indirect) with the process. The stylist that I am going to in Northridge, CA has done several AA heads. So, during my consultation, I will be grilling him on the long term effects on his other clients, maintenance, etc.
Dolce Dawn, I am considering this rather than a conventional relaxer because I've spent about twenty years with relaxers, and no matter what the situation/stylist/ etc., my hair doesn't thrive with a conventional relaxer. Since conventional relaxers basically dissolve the outer layer of the hair shaft, my hair (the individual strands are very fine, but I've got a lot of stands) gets broken down too easily and ends up damaged, frizzy, etc. I'm considering the Japanese straightener because the chemical used is less caustic than a conventional relaxer. And, the results that I have seen have been much silkier than most relaxers.
Falon, I agree. The flat irons make me nervous also. However, I am going to have a strand test done and wait a while to see how it goes for a couple of weeks. I expect to do the same things with my new growth that I do now, a very light press and flat iron. But, I have to make sure that this will not cause damage.
