I use a permanet Hair straightener by Salerm Cosmetics. It is the only product that does not bother my scalp.
The ingredients are these:
Aqua, cetearyl Alcohol, Amonium Thoglycolate, Glycerin, Polysorbate 60, Cetyl Alcohol, Parafinum Liquidum, Hydrolized Keratin, Bisabolol, Potassium Stearate, Sodium Lauryl Sulfate, Glycol Stearate, Tetrasodium EDTA, Triethanolamine, Amonium Hydroxyde, Diammonium Dithiodyglycolate, Parfum.
What is the actual straightening chemical in this product?
