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 C.sub.10-30 and C.sub.10-30 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 C.sub.1-30 alkyl, C.sub.2-30 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.

Hair styling composition and method

Transglutaminase crosslinks proteins by catalyzing the formation of isopeptide bonds between lysine and glutamine residues. Transglutaminase may be used to crosslink beneficial actives containing an amine moiety to glutamine residues in skin, hair or nails. A variety of beneficial actives, e.g., sunscreens, antimicrobial compounds, skin conditioning agents, hair conditioning agents, anti-inflammatory compounds, antioxidants, coloring agents, perfumes, insect repellants, can thus be delivered to human skin, hair, or nails.
