Abstract

Traditionally, hair care has always focused on the visible part of hair: the hair shaft. Nowadays, we know that stress, pollution, nutrition, UV radiation, etc., they all affect the whole hair structure, including the scalp and the follicle. All these factors generate oxidative stress on both scalp and hair, finally causing scalp redness and flaking as well as hair breakage and fragility.
The new active Encapsulated Olea Europaea Callus Culture Lysate (EOECCL) nourishes and reinforces all the elements of the hair structure, improving its volume, hydration, and shine from within. Made from Olea europaea (olive) stem cells, the active ingredient’s mechanism of action consists in delivering a nourishing proteo-lipidic matrix to both the scalp and the hair cortex to strengthen, volumize, hydrate and revitalize the damaged hair and scalp. Several in vitro, ex vivo and in vivo trials demonstrate the ingredient’s activity and the new concept of restoring the Hair Tensegrity. A new way to deal with hair care, considering a ‘skinification’ approach.

INTRODUCTION
The Hair tensegrity: applying an architecture-inspired concept to hair care
The hair structure is a unit where scalp, follicle and shaft must be considered as a whole (1, 2). Scalp is the hidden essential in hair biology and is responsible for the nourishing, biology, and mechanical behaviours of the pilosebaceous unit. Therefore, all the parts of hair are interconnected and the whole hair system can be revitalized based on the new concept of hair tensegrity.

The term “tensegrity” comes from architecture and is coined from the contraction of the terms “tensional” and “integrity” (components of any structure which are under compression while they are inside a network in continuous tension) (3). Tensegrity explains how changes applied to an area of a given structure will also exert effects at a distance because everything is interconnected.

For instance, a skyscraper must have a good tensegrity (being strong enough, but also flexible enough to resist the wind at high altitude). Following this analogy, a healthy hair must have a good tensegrity (being strong enough ...
