Embodiments described herein relate generally to apparatus, methods and systems for low energy processing of consumer personal hygiene products (PHPs) and formulations of the same. In some embodiments, a method of manufacturing a consumer PHP comprises combining a first material and second material at room temperature to form a first mixture, mixing the first mixture at room temperature, adding a third material at room temperature to form a second mixture; mixing the second mixture at room temperature, adding a fourth material at room temperature to form a third mixture; and mixing the third mixture at room temperature. In some embodiments, the third material and the fourth material can be mixed to form the second mixture and the first mixture and second mixture can be combined to form the third mixture. In some embodiments, the mixing can be accomplished using a propeller mixer. In some embodiments, the propeller mixer can be rotated at a speed of greater than about 200 rpm during at least one of the mixing steps. In some embodiments, the pH of the third mixture can be adjusted to between about 4.5 and about 6.5 using an acidifier. In some embodiments, the viscosity of the third mixture can be adjusted to between about 100 cP and about 25,000 cP using a thickener.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.
