Pregnancy and Permanent Hair Straightening
I have actually had chemists and scientists with Masters and PhD's ask me this question after they are sitting in my chair for their straightening. No hairstylist can legally answer that question as it is considered by the State of Texas as, "practicing medicine without a license." You should always ask your doctor. They know the answer off the top of their head. They have responded to that concern for innumerable excited parent's-to-be. I am glad that you asked before you made your appointment. The following information will save time and ensure your doctor knows what service and chemicals you are referring to. Active Ingredient: Ammonium Thioglycolate.(Chemically breaks the disulfide bonds in order to be re-arranged later with the flat iron.) It is not applied within 1/2" of the skin but does makes brief contact with the scalp during the 7-minute thorough rinse. An odor of ammonia is experienced and inhaled during the application and processing of the first solution, but not enough to have ever involved OSHA regulations. No odor beyond that except usual scents from conditioners applied.
The neutralizer: A low-levelhydrogen peroxide solution -about 1.5% (which re-bonds the sulfides making the altered texture permanent) That info will help your doctor advise you. Let me know if you'd like me to send a .pdf file of the Material Safety Data Sheets, or MSDS info of the exact products I use for your doctor to review.
