Silicone and Oil Hair Serum
One hair serum that I have contains the following ingredients: Cyclopentasiloxane, Dimethicone, C12 15 Alkyl Benzoate, Argania Spinosa Kernel Oil, Mauritia Flexuosa Fruit Oil, Hydrogenated Castor Oil, Hydrogenated Castor Oil/Sebacic Acid Copolymer, Benzyl Salicylate, Citronellol, Geraniol, Hexyl Cinnamal, Limonene, Linalool, Fragrance. What exactly does hydrogenated castor oil/sebacic acid copolymer do? Also, what is the difference between dimethicone and dimethiconol? Is it better to use a serum on damp or dry hair?
