Most hair conditioner products do a good job of what they are designed for:
* Rinse detangling type products, add some shine and reduce static electricity. They work on the surface of the hair
* “thickening” products may contain protein, which can act as a filler in damaged areas. While all of these products help, for the most part, they are harmful to straightened or treated hair because they contain so much fragrance and chemicals. SaoLindas mask differs in that it is more concentrated, incorporates into hair with heat and has been relied upon by beauty salons for decades, without affecting hair straightening effectiveness.
