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?


  • Hydrogenated Castor Oil/Sebacic Acid Copolymer supposedly sticks to lifted cuticles and cements them down. Theoretically this can help with split ends. 

    Dimethiconol is a more water soluble version of dimethicone which means it gives less buildup but it's not as effective. 

    Damp or or dry is a matter of personal preference.
