In one particular embodiment, the cleansing composition may comprise a hand soap composition. In accordance with the present disclosure, the cleansing composition contains a color changing indicator that changes color based upon changes in temperature. Specifically, during use of the cleansing composition, the composition increases in temperature due to various factors. For instance, when the cleansing composition is intended to clean part of a person's body, such as a hand soap, the temperature of the composition may increase due to contact with the user, due to friction that is caused during washing and/or due to the presence of warm water.

When the cleansing product is used to clean adjacent surfaces, on the other hand, the temperature of the composition may increase due to friction that is generated during scrubbing, due to contact with a person's hand and/or due to the presence of warm water. In accordance with the present disclosure, once the cleansing composition reaches a selected temperature, the composition can be configured to discontinue changing color indicating to the user that the user has spent sufficient time washing, wiping or scrubbing.

Psoriasis is one of the most common skin ailments among all chronic skin diseases. This disease is found in 1.4 to 2.9% of the population. The scalp is one of the favored sites for psoriasis; the latter causes essentially erythemas, desquamations, hyperkeratoses or pruritides and can also be responsible for a reduction in hair density. The treatments used to date involve salicylic acid, local steroids, anthralin, or coal or wood tar. These treatments are unpleasant, in particular when tar is applied, and require lengthy applications, in particular when hair ointments are used.
