A hair styling and conditioning process comprising the steps of: contacting the hair with a compound having an electrophilic group and at least one hydrophobic group whereby the electrophilic group reacts with nucleophilic sites in and on the hair to give the hair a plurality of hydrophobic groups at the surface, in which the hydrophobic group is selected from the group consisting of C10-30 and C10-30 alkenyl groups. Preferably the electrophilic group is azlactone. Also a reversible hair styling process in which the hydrophobic group is selected from the group consisting of C1-30 alkyl, C2-30 alkenyl, phenyl, diphenyl, other aromatics, and fluoroalkanes, and the electrophilic group is selected from the group consisting of azlactone, sulphide from disulphide, sulphide from thiosulphonate, vinyl zulphone, vinyl sulphoximines, banzoxazinones and isocyanates. Novel azlactones, including pentadecyl and hexyl azlactone. |
