Claims62
A method of straightening hair, the method comprising;
- applying a composition to hair, the composition including an alkaline earth metal hydroxide and guanidine carbonate included in an aqueous solution wherein the alkaline earth metal hydroxide is selected from the group consisting of calcium hydroxide, sodium hydroxide, barium hydroxide, lithium hydroxide, and potassium hydroxide, the guanidine carbonate having a concentration of about 5.68% to about 17.06% by weight, based on the total weight of the aqueous solution;
- heating the composition and hair;
- and
- removing the composition from the hair.
1 more element
A composition for use in straightening hair consisting of:
- a first ingredient which includes calcium hydroxide having a concentration of about 1.21% by weight to about 3.45% by weight, based on the total weight of the first ingredient;
- a second ingredient which includes guanidine carbonate having a concentration of about 5.68% by weight to about 17.06% by weight, based on the total weight of the second ingredient;
- and
- wherein the first ingredient and the second ingredient are combined to produce a hair straightening composition.
