PDF] Study on the Morphological Change of Straight Permanent Waved Hair by Tensile Strength Test

By A Mystery Man Writer

Description
ABSTRACT In this study, we investigated tensile properties and ultrastructural changes of straight permed hair using the rheometerand the scanning electron microscopy. First, we compared the morphological characteristic between the virgin hair and thestraight permed hair after testing tensile strength. Cuticle cells were heavily lifted off in straight permed hair than in thevirgin hair. Cuticle cells were separated by the destruction of intercellular membrane complex and no destruction or dam-age were found in cytoplasm. In the comparative test for tensile characteristic between the virgin hair and the straight perm-ed hair, tensile distance of the straight permed hair was decreased by 24.5% or 3.05mm than the virgin hair. The tensilestrength was decreased by 34.63% or 5.62g/cm 2 and the maximum stress by 34.59% or 56.12g. As a result, the tensileproperty dropped to the lowest level with the straight permed hair than with the bleached hair or the permanent dyed hairof previous studies.Keywords : Straight permed hair, Tensile strength, Rheometer, Scanning electron microscopy
