WHAT IF, IN A FEW DAYS, YOU REGAINED THE NATURAL COLOR OF YOUR HAIR? Anti-grey hair spray. The Claude Bell Institute's radical solution against grey hair. Treatment satisfaction close to 100%! GREY AWAY is a revolutionary treatment designed to restore grey hair to its original colour. The treatment is simple, fast and without embarrassment. Daily use, between 14 and 28 days, in the morning on dry hair will re-pigment the hair in a natural and gradual way. Thereafter, i.e. after 28 days, a simple use once a week is necessary to prevent the growth of new grey hair at the root. Why does hair turn gray? In reality, hair does not turn gray, but white! It is an optical illusion related to the mixture of colored hair and white hair. Thus, the hair appears more and more gray as the percentage of gray hair increases. The phenomenon of hair bleaching is called canitia. Hair grows white when it is no longer pigmented, when melanocytes are no longer able to transmit melanin to keratinocytes, cells that make up most of the epidermis. Melanin is a natural molecule produced by special cells called melanocytes mainly located in the epidermis and whose essential role is to protect the skin from UV rays from solar radiation. As this melanin is a coloured substance (also known as a "pigment"), it gives the tissues that contain it (skin, but also hair) a more or less intense colour depending on the quantity present. Grey Away and the memory of hair: Wasabia japonica. A few years ago, the laboratory developed a formula that gradually re-pigments the hair: GREY AWAY. The main active ingredient in this treatment is extracts of the roots of Wasabia japonica, a perennial plant of the Brassicaceae family that grows naturally along mountain rivers and streams in Japan. The other components are there to stabilize the active ingredients, ensure the effectiveness of GREY AWAY and give it its cosmetic qualities. The active ingredient comes in soluble form in the product and penetrates when applied to the dry hair shaft. In the minutes that follow, a deposit and an oxidation-reduction reaction occur, with the active ingredient reacting with the hair's keratin. It becomes insoluble and gives a dark coloration. Once precipitated in this form, it is stable and remains fixed. The colouring is adjustable according to the number of applications, and therefore the amount of active ingredient that is fixed. To our knowledge, there is no known explanation for the natural regeneration of the hue, but this phenomenon is classically observed with this type of active ingredient. We can thus speak of "hair memory". Clinical Tests: Clinical test results demonstrate in vivo: - A 46% disappearance of grey hair after 14 days of treatment,- A disappearance of 83% of grey hair after 28 days of treatment,- A treatment satisfaction rate close to 100%. Directions for use: As an attack treatment, you will apply the spray every morning to your dry hair, without any particular precautions. This morning application is preferable because of the positive action of daylight on the effectiveness of the active ingredient. This daily treatment will last between 14 and 28 days, until your hair has returned to its natural shade. As a maintenance treatment, you will use GREY AWAY only once a week to maintain the regained colour. GREY AWAY does not contain lead acetate or parabens. 1 spray of 200 ml
