@evolutionsalonrb: Replying to @yuleee222 #japanesestraightening also known as #thermalreconditioning #permanentstraightening is a completely different process from a #brazilianblowout or #keratintreatment (those are Demi -permanent smoothing treatments that do not break the bonds of the hair, they do not straighten. Their primary goal is to smooth and remove frizz while reducing curl minimally) This straightening treatment completely straightens the hair. It lasts until it grows out and gets cut off. the solution is rinsed-so during the blowdry/flat iron process there are no fumes nor gases emitted. Let me know if you have any other questions!
