A single formula, mild permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl and leaves the hair soft while minimizing further damage to already damaged hair. The composition contains a cysteamine reducing agent compound selected from the group consisting of cysteamine, a cysteamine salt, and mixtures thereof. The cysteamine compound should be present in an amount of at least about 7.8% by weight and preferably in the range of about 7.8% to about 12.5% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to at least about 7.8 preferably about 7.8 to about 8.8. Optionally, a hair softening and/or moisturizing agent, such as glycerine is included in the composition in an amount of about 0.1% to about 15% by weight of the composition. The composition can be lotion or water wrapped and can be used with or without heat. Unexpectedly, the composition is applied to any type of hair, regardless of structural damage to the hair, resulting in the same degree of curl tightness and softness and can be applied much more frequently than prior art permanent wave compositions without significant damage to the hair.

Cysteamine permanent wave composition and method

A single formula, mild permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl and leaves the hair soft while minimizing further damage to already damaged hair. The composition contains a cysteamine reducing agent compound selected from the group consisting of cysteamine, a cysteamine salt, and mixtures thereof; preferably alone (without a monothioglycolate; a monothioglycolic acid ester, e.g., thioglycerol; a thiolactic acid; a sulfite; a hyposulfite, or a bisulfite second reducing agent). The cysteamine compound should be present in an amount of about 7.8% to about 9.0% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to about 7.8 to about 8.5. Optionally, a hair softening and/or moisturizing agent, such as glycerine is included in the composition in an amount of about 0.1% to about 15% by weight of the composition.

The composition contains a cysteamine reducing agent compound selected from the group consisting of cysteamine, a cysteamine salt, and mixtures thereof; and a second reducing agent selected from the group consisting of a monothioglycolate; an alkanolamine salt of thioglycolic acid; a thiolactic acid; a thioglycolic acid; thioglycerin; salts of thiolactic acid; cysteine; a salt of cysteine; a sulfite; a hyposulfite; and a bisulfite. The cysteamine compound should be present in an amount of about 7.8% to about 9% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to about 7.8 to about 8.8. Unexpectedly, the composition is applied to any type of hair, regardless of structural damage to the hair, resulting in the same degree of curl tightness and softness and can be applied much more frequently than prior art permanent wave compositions without significant damage to the hair.

Cysteamine permament wave composition and method

A mild, alkaline permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl like an alkaline permanent wave composition but leaves the hair soft like an acid permanent wave composition and leaves essentially no post-perm odor. The composition contains about 2.0% to about 6.5% by weight of a cysteine reducing agent compound selected from the group consisting of cysteine, a cysteine salt, and mixtures thereof; about 4.5% to about 8.0% of a thioglycolate; and sufficient additional alkali, if necessary, to bring the pH of the composition within the rang of about 7.5 to about 9.5.
