In lab tests on chemically straightened hair, jojoba oil and silicone conditioning agents reduced protein loss and improved resistance to breakage.
Laboratory study on Afro-ethnic hair locks processed with a thioglycolate straightener; adding conditioning agents reduced protein loss and improved breakage resistance, with jojoba oil among the best performers. Hair-tress study, not a trial in people.
In lab tests on hair, guar hydroxypropyltrimonium chloride improved deposition of conditioning oils and dimethicone onto hair.
Laboratory comparison of cationic conditioning polymers on virgin hair, measuring oil deposition, combing energy and friction; guar hydroxypropyltrimonium chloride gave superior deposition of natural oils and dimethicone. Hair-sample study, not a trial in people.
In lab image analysis of hair tresses, amodimethicone-type silicones increased the measured shine (luster) of hair.
Laboratory study using image analysis of light reflected from hair tresses; cosmetic oils including amodimethicone raised luster indices. Hair-tress study only.
