Are Aminexil, Amino Acids, Peptides, And Herbal Ingredients In Hair Treatments Safe When Planning Pregnancy?

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?
