It would be desirable to provide anhydrous self-warming hair care compositions. These rinse-out compositions are first applied to the hair, and then when contacted with water they generate heat and give a perception of warmth, to the user. The perception of warmth is desirable, because it serves as a signal or cue to the user, that the composition works, and provides warmth and relation.
Alternately, water could be applied to hair first and then the rinse-out compositions could be applied, or water and rinse-out compositions could be simultaneously applied to the hair. All of these methods would generate heat.
Such, rinse-out compositions can take the form of shampoos, conditioners, or 2 in 1 products that is compositions that are; both shampoos and conditioners.
Known anhydrous self-warming rinse-out hair care compositions have deficiencies in rheology and conditioning ability. It would be desirable to overcome these deficiencies in rheology and conditioning ability.
