formulations and methods for keratin treatment formulations, kits and methods for reconstructing disulfide bonds in keratin found in hair, skin or nails. Hair that is damaged during a hair coloring treatment and / or other reducing treatment, such as during a permanent wave, can be treated with formulations containing one or more active agents. the formulations can be applied subsequently to a hair coloring treatment or simultaneously with a hair coloring treatment. the use of active agent formulations during a permanent wave treatment prevents the hair from reverting to its previous state for at least one week, preferably at least three months, more preferably at least one year, more preferably more than one year , after one or more of an application of the formulation. applying the active agent formulation to the skin or nails can help repair damaged disulfide bonds due to natural wear and natural aging. |
