Lubrizol Life Science Beauty has released tests for Fensebiome peptide (INCI: Water (Aqua) (and) Acetyl Heptapeptide-4 (and) Caprylyl Glycol) when applied to the scalp.
The data showed an increase in beneficial scalp microbiota that tends to decrease with age and a modulation of age-induced microbiota changes, associated with a rejuvenated and healthier scalp.
The ingredient was also tested on two panels of volunteers: a group of women with sensitive scalps and a group of men with bald sensitive scalps. Both groups found that the ingredient soothed the scalp, leaving it feeling hydrated and with less itchiness and desquamation, per the company.

In vitro tests also showed a reduction of Kallicrein-5 and PAR-2 activation, which helps relieve inflammatory and itching skin and scalp conditions.
Previously, the ingredient was shown to have effects on the skin by reinforcing the double cutaneous barrier, promoting microbiota balance and enhancing the physical barrier, helping to achieve a healthier and younger appearance, per the company.
The heptapeptide can now be incorporated into scalp formulations designed to reduce sensitivity, prevent dehydration and rejuvenate the scalp as well as form part of skin care products aiming to strengthen the double cutaneous barrier, per the company.
