The scalp is exposed to daily aggressions, particularly from the exposome. This can influence hair health. In fact, in China, over 90 % of hair product users believe that scalp care can improve the health of their hair*.
Seppic therefore decided to re-explore the potential of Alariane CV (Inci: Aqua/Water - Butylene Glycol - Alaria Esculenta extract) to offer a dual effect on the scalp: protection of hair follicle cells and scalp lipids against the exposome.
Alariane CV is an extract of Alaria esculentaa food traditionally consumed along the coasts of the far north Atlantic Ocean, for its excellent health properties and its binding/detoxifying effect against heavy metals, also known as "Irish wakame".
Tests were carried out during exposure to cadmium, a heavy metal present in global pollution from cigarette smoke or phosphate fertilizers, for example.
In contact with cadmium, the scalp is weakened and subjected to inflammation, so hair follicles are no longer able to produce healthy hair.
Seppic points out that the use of Alariane CV has demonstrated, through protocols in vitroA significant 2 7% reduction in hair follicle inflammation compared to an untreated follicle, after Cadmium stress.
Microscopic observations of cells in the presence of Alariane CV showed an increase in their number and an improvement in their morphology, similar to cells not exposed to Cadmium.
Seppic claims that Alariane CV has a protective action on the hair follicle against Cadmium-induced inflammation, and helps preserve scalp function and maintain healthy hair. According to the company in vitro have also shown protection against lipid peroxidation after UVB stress.
