  Keratin straightening

  Posted by Benyamin on May 21, 2023 at 8:30 am

  Hello, I have made two hair straightening formulas, in the first formula I have used methylene glycol for smoothness, surfactants and silicones… and in the second formula, I have used glyoxylic acid and glycolic acid for smoothness and amino acids, glutamic acid.. …I have used it, I want to use a thermally activated substance such as urea or amines for more penetration.??
