Abstract: Conditioning composition comprising a quaternary conditioning surfactant, an acid neutralized amidoamine surfactant of general formula: R1-C(O)-NH-R2-N(R3)(R4) wherein R1 is a fatty acid chain with from 12 to 22 carbon atoms, R2 is an alkylene group containing from one to 4 carbon atoms and R3 and R4 are, independently, an alkyl group having from one to four carbon atoms and from 0.45 to 4% wt. of the composition lactic acid.

Abstract: Device for measuring hair damage comprising a handle (2) and a shaft (3) and a mandrel, a clip (4) and a feedback indicator, wherein the mandrel and clip are attachable to the shaft and the mandrel is drivable along the length of the shaft to measure the friction of a lock of hair which is wound around the mandrel and back onto itself and held in place by the clip such that fibres in the lock of hair are rubbed against themselves along the general direction of the hair fibres and use of such a device.

Abstract: Hair and/or scalp treatment compositions comprise an antidandruff agent, an effective amount of a cannabinoid receptor (CBR) activating agent and a cosmetically acceptable diluent or carrier. Alternatively, the compositions may be shampoo compositions comprising from 3 to 50 wt % surfactant, a CB receptor activating agent and a cosmetically acceptable diluent or carrier, provided that the CB receptor activating agent is not palmitoylethanolamide. The compositions are useful in the treatment and/or prevention of the symptoms of dandruff and can reduce scalp itch, a symptom which is typically associated with dandruff.

Abstract: A composition for topical application to the scalp comprises (i) an anti-dandruff agent; (ii) conjugated linoleic acid; and (iii) a cosmetically acceptable diluent or carrier.

Abstract: Metal pyrithiones, such as zinc pyrithione, can be used to increase the level of lipids in the stratum corneum of the skin.

Abstract: Dandruff and symptoms of dandruff can be treated using lipophilic agents or lipid precursor and/or promoters to strengthen the scalp. The lipophilic agents or lipid precursor and/or promoters are preferably used in conjunction with an antifungal agent which has activity against Malassezia spp, particularly Malassezia furfur. Suitable antifungal agents include those conventionally used for the treatment of dandruff including, for example, zinc pyrithrone (ZnPTO), octopirox and azole antifungal agents such as climbazole and ketocanazole. The antifungal agents may be used singularly or as a mixture of one or more antifungal agents.

Abstract: 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.
