The role of oxidative damage in poor scalp health: ramifications to causality and associated hair growth

The oxidative stress element of unhealthy scalp leads to compromised pre-emergent hair formation and poorly formed hair as it grows. Only cosmetic solutions can minimize the impact of unhealthy hair and to achieve healthy looking and feeling hair, the scalp health must be normalized first. The objectives of this research were to both investigate whether oxidative stress was a relevant aetiological element in scalp dandruff and seborrhoeic dermatitis and whether scalp condition affects the quality of hair that grows from it. Further, this research was designed to determine whether an effective anti-dandruff shampoo would repair and protect the scalp and pre-emergent hair from oxidative stress. This study demonstrated that oxidative stress is an aetiological element relevant to the dandruff condition and that a potentiated ZPT shampoo effectively improves scalp condition, including a reduction in oxidative stress. The compromised hair condition associated with dandruff is concomitantly improved when the scalp condition is improved. It appears that there is a direct link between hair quality and scalp health. Resume La composante de stress oxydatif du cuir chevelu en mauvaise sante compromet la qualite du cheveu en formation et celle du cheveu en croissance. Seules des solutions cosmetiques peuvent le minimiser et pour obtenir un cheveu a l'apparence et au toucher sains, le cuir chevelu doit etre d'abord normalise. L'objectif de cette recherche etait a la fois de determiner si le stress oxydatif est un element etiologique pertinent dans le cuir chevelu a pellicules et la dermatite seborrheique et si l’etat du cuir chevelu affecte la qualite des cheveux qui y poussent. De plus, cette recherche a ete concue pour determiner si un shampoing anti-pelliculaire efficace serait capable de reparer et de proteger le cuir chevelu et les cheveux avant leur croissance du stress oxydatif. Cette etude a demontre que le stress oxydatif est un element etiologique pertinent a l’etat pelliculaire et un shampooing au pyrithione de zinc ameliore efficacement l’etat du cuir chevelu, et permet une reduction du stress oxydatif. L’etat de la chevelure abimee par les pellicules est ameliore de facon concomitante a l'amelioration de l’etat du cuir chevelu. Il s'avere qu'il y a un lien direct entre la qualite des cheveux et la sante du cuir chevelu.
