Hello Doctor, I'm 25 Years Old And Plan To Be

Hello Doctor, I'm 25 years old and plan to be pregnant. I'm currently in hair-treatment therapy. The specialist said that they use CNC to open hair follicles and deliver active ingredients such as Aminexil, Amino acid & biological peptide, extra herbs (saw palmetto, ginseng) that support and stimulate hair growth. Can you advise me that these substances are safe for my pregnancy?
