The heat perm is the preferred hair technique to get positive affects such as increase of work efficiency and sale in hair industry. The subjects of this study is 262 hair shop workers and it was investigated heat perm device using reason, using satisfaction and repurchase. As a result, the perm accounted for 32.1 and the use of digital perm devices was more than that of setting perm devices. The reasons for the use were that the longer the setting device was engaged, the flexible it was the hair wave. The higher the rank, the better the hair wave retention and the long hair treatment, and it also helped sales. (p<0.05) Digital perm device can be hair-wavy in the desired style while in use, and the longer the working period, the more advantageous. The repurchase intention was that the longer the period of service and the higher the rank, the more advantageous it was. (p<0.05) The reasons for the usage of setting perm and digital perm were correlated with the satisfaction of use and the repurchase intention. The reasons for the use were helpful for sales and elastic hair wave and long hair waving was possible, which affected the repurchase. In conclusion, heat perm had been found not only helped sales, made a good hair wave, and the long hair waving, but also to be preferred to the long working period of the hair shop and the rank above the designer.

Human hair could be damaged by various physicochemical conditions and treatment. Permanent and decoloring treatment were the most serious factor on hair damage. The new permanent wave lotion containing Permeation enhancers such as Cremophor EL, Transcutol and propylene glycol based on cysteine permanent wave lotion were prepared. Efficiency of permanent wave and hair damage following pH of permanent wave lotion and addition of permeation enhancer were investigated. PH of solution, wave efficiency, loss of protein from hair, morphology of hair by SEM and solubility of alkaline solution were evaluated. The addition of Cremophor EL and Transcutol with ethanol increased permanent wave efficacy and decreased hair damage effectively. They diminished permanent wave lotion's pH and augmented permanent wave lotion's penetration compare to cysteine permanent wave lotion. new permanent wave lotion containing permeation enhancers such as Cremophor EL could be a good candidate for a new permanent wave lotion.

Appearance management through hair beauty forms the basis of the beauty industry, while permanent waves using heat are often used in hair salons, but hair damage due to thermal permanent wave treatment is an inevitable reality. Therefore, this study was conducted for the purpose of presenting an efficient method for thermal permanent wave that can further increase hair wave formation ability and minimize customer's hair damage. After collecting virgin hair from the occipital region, thermal rod pretreatment and thermal permanent wave treatment were performed, and hair roughness analysis and 3D-image were studied using an Atomic Force Microscope. As a result of the study, both the average roughness (Ra) and the ten point average roughness (Rz) were calculated as 223 nm and 853 nm for 4 sections, respectively, showing the highest values. Although the number of samples of the experimental data is limited, the wave forming power can be further increased through this study, and it is expected that it will be practically possible to propose an objective method for thermal permanent wave that can minimize hair damage as well as protect the cuticle of the customer's hair.Judge.
