Abstract (en)
[origin: WO2023121639A1] A method of protecting hair from damage by applying a long-chain unhydrolyzed alkyltrialkoxysilane to hair shafts and then hydrolyzing and polymerizing the alkyltrialkoxysilane to form a non-penetrating outer layer on the hair shaft by utilizing pH adjusted water followed by the application of heat. Alternatively, the alkyltrialkoxysilane may be applied to the hair in combination with an alkyl or alkenyl succinic anhydride prior to the application of heat.
