Formulations, kits and methods for rebuilding disulfide bonds in keratin present in hair, skin or nails. Hair damaged, such as during permanent waves, as a result of coloring treatments and/or other reducing treatments, may be treated with formulations containing one or more active agents. The formulation can be applied after or concurrently with the hair coloring treatment. Use of the active agent formulation during permanent wave treatment to prevent hair from returning to its previous state, for at least one week, preferably at least three months, more preferably at least one year, most preferably after one or more applications of the formulation more than a year. Application of the active agent formulation to the skin or nails can help repair disulfide bonds damaged by natural wear and tear or natural aging. |
