PURPOSE:To obtain an article having good handleability, being directly or indirectly brought into contact with the air, promoting growth of the hair, further blackening effects on white hair from the borders of the hair, by processing alumina-containing ceramic as a basic raw material into a product. CONSTITUTION:Alumina-containing ceramic as a basic raw material is processed into a product. Powder, particles, whiskers of the ceramic or ceramic fibers are used alone or a combination thereof is used as the basic raw material, made into a structure or a shape for convenient use or mixed with other materials and directly or indirectly brought into contact with the hair. For example, a sheet comprising the ceramic fibers as a base material is bonded to a readily handleable vinyl sheet for preventing damage to give a lamellar material, which is put on a pillow in sleeping and brought into contact with the ear in use. |
