No. KSD is not a relaxer and it is not a reverse perm. It is a new and different technology. KSD gently modifies and restructures the disulfide bonds in the hair to soften the overall shape of the curl.  Lye relaxers use sodium hydroxide with a pH of 12-14.  There are “no-lye”relaxers which use guanidine carbonate, with a pH of 9-11.  Japanese straighteners use ammonium thioglycolate with a pH of 9 to 9.6. These products are strongly alkaline, and a neutralizer must be used.  If the process is not timed correctly, these alkaline products can quickly destroy the hair. KSD is not alkaline at all. It does not contain sodium hydroxide, guanidine carbonate or ammonium thioglycolate.
