ABSTRACT:
The penetration or absorption of water, oils, collagen, and other materials into the hair is greatly increased by adding a small quantity of inorganic charged colloidal silica to provide an aqueous suspension of the charged colloidal silica particles along with the material to be absorbed into the hair. In coloring hair, dye components can be absorbed into the hair without the use of alkaline solutions which damage the hair, and in perming hair, the disulfide bonds in the hair can be broken by tension caused by swelling due to water absorption in the hair, again without the use of damaging alkaline solutions. It is believed that the porosity and stable hydration of the hair can be varied through altering the electrostatic charge on the hair. The aqueous suspension of charged silica particles applied to the hair appears to alter this charge.
