The segregated hairs were soaked in hot water and washed
several times with detergent. Then, they were rinsed with hot
water and dried in natural sunlight for 48 h. The morphology and
cross sections of a sample of each of the three different hair types
(A, B and C) were examined using a JEOL scanning electron
microscope model JSM 5410LV (JEOL (SEM), Japan).
