Do the types of products/systems used for Hair Straightening make a difference or are they all the same?
Technically, the main chemical ingredients in most of the Japanese Hair Straightening systems are Thioglycolic Acid and Ammonia. There are several milder, less effective ingredients offered in other straightening processes. Japanese Hair Straightening or Thermal Hair Straightening is a procedure combining both chemical and Thermal heat processes. The well-known over the counter relaxers contain Lye which is the main chemical ingredient. Typically Lye content relaxers are not used with the Thermal Hair Straightening process.
