The morphological changes were investigated for the purpose of suggest the basic information to lesson hair damages of children(female) and women by the treatment of perm and coloring. perm and coloring were treated one time and tree times at a week's interval at different temperature(25℃, 50℃), respectively.
The virgin hairs, which were not treated with perm and coloring were morphologically healthy. All of the hair cuticle strata were well settled.
Children's perm hairs, which were treated one tine at 25 ℃, were relatively healthy though one or two spots were unsettled. On the occasion of perm hairs treated three times at 25 ℃, most of the hair cuticle strata were unsettled, and four or five spots were cracked. On the occasion of perm hairs treated one time at 50 ℃, one or two sports of the hair were cracked, and two or three spots were tom. On the occasion of perm hairs treated three times at 50 ℃, most of the hair cuticle strata were unsettled and cracked.
The damages of women's hairs were much less than those of children's hairs. Women's perm hairs, Which were treated one time at 25 ℃, were mot damaged at all. On the occasion of perm hairs treated one time at 50 ℃, one or two spots of the hair were cracked and torn, but very clean. But, on the occasion of perm hairs treated three times at 50 ℃, many cuticle strata were cracked and were in pieces.
The damages of children's coloring hairs, which were treated one time at 25 ℃, were very little. On the occasion of coloring hairs treated three tomes at 25℃, most of the hair cuticle strata were unsettled. On the occasion of coloring hairs treated three tines at 50 ℃, all of the hair cuticle strata unsettled and five of six spots were cracked, and four or five spots melted. After coloring like perm treatment, the damages of women's hairs were also much less than those of children's hairs.
