Scientific Facts & Research THE VITAL ROLE OF RHODANIDE The rhodanide molecule consists of nitrogen, carbon and sulphur (sulphur is nick-named the ‘beauty mineral’ because it keeps hair shiny and healthy). Hair loses on average 36% of its natural rhodanide level with each washing. The scalp needs several days to replenish the lost rhodanide, which will automatically lead to rhodanide deficiency if hair is washed daily. A twice weekly application of rhodanide is sufficient for the hair to establish a rhodanide depot. Rhodanide, when applied topically to the scalp penetrates along the hair shaft to the roots of the hair and remains there without further invading host. On the one hand rhodanide activates the hair’s growing cells, increases cell division by supporting the proliferation of fibroblasts of the hair follicle, as well as promoting connecting tissue formation such as with hair keratin. On the other hand rhodanide is a very active anion with a high ability bonding strength in different valences, enabling participation in many biochemical communication / reactions.
Rhodanide has a high ability to bond proteins. It strengthens and stabilizes the sulphur-hydrogen bonds of the keratin enabling formation of highly-netted keratin connections between cuticle layers and cortex, thus increasing the resistance of keratin structures i.e. strengthening hair from within, resulting in, stable, stronger, more elastic hair, with increased volume, improved manageability and resistance to damage. Stronger bonding between hair cuticle and cortex also allows improved cuticle scale alignment protecting cortex from damaging external factors. Proper alignment of hair cuticle scales leaves hair shinier due to improved light reflection. The natural shine of hair does not result from any topically applied substance but derives from the light reflection of well aligned cuticle scales on the outer layer of the hair. If cuticle scales are damaged, or not in place the hair lacks protection from all external influences e.g. like a house without a roof. As a natural moisturizing factor rhodanide improves the water binding capability of hair; increasing moisture content by 50%, resulting in an improvement in the hair’s physio-chemical qualities such as volume, elasticity, strength and manageability. Hair remains strong and resistant to mechanical stress and tensile strength is significantly higher compared with untreated hair. This is a lasting effect, since hair treated with rhodanide and dried over a period of 24 hours has a higher mass than untreated hair. Copyright © Hair Care Foundation Pty Ltd 2006
