Phenyl Trimethyl Polysiloxane
Among all the silicones used in trichological formulas, it has the highest light refractive index. Thanks to its special polymer structure, it doesn’t penetrate the hair, but coats its outermost layer. This coating reflects the light that reaches it, finding a smooth and even surface. Consequently it increases the hair’s splendor and glossiness, giving it a pleasant “satin” effect.
