With the advancement of the society and the improvement in the quality of life, a wide array of hair products, including hair perm solutions, was developed to meet the needs of various types of consumer. A survey conducted in 2007 revealed that 79.4% (54 cases) of the surveyed perm solutions in the Taiwanese market had incomplete ingredient labels [1]. It is also known that the more the hair was permed, the greater the keratin loss in the hair [2]. In typical hair perming, thioglycolic acid (TGA) is used as the main ingredient in alkaline perm solutions to cleave the disulfide bonds in the hair, in order to alter the waving of the hair. During the perming process, the first perm solution, a reducing agent, penetrates the hair and cleaves about 45% of the disulfide bonds therein, forming single thiol groups, which are then pressed, reshaped and moved by hair curlers of various shapes, diameters and tensile strengths ; the second solution, an oxidizing agent, then brings together the thiol at the new position with another thiol, forming a new disulfide bond, thus resulting in permanent hair modification. In general, hair perm solutions are categorized into three types : acid, cysteine and alkaline. Liposome is a phosphatidyl choline (PC)-based microparticle ; it has a hollow sphere capable of encapsulating molecules, thus making liposome a possible delivery vehicle. Due to its excellent permeability to biological membranes, liposomes have been extensively studied and implemented in various applications. Having both polar and non-polar characteristics, phospholipid liposome may also act as a surfactant ; it can bind to most proteins and forms a stable lipoprotein structure, which makes liposome a strong emulsifying agent [3,4]. Previous research results indicated that phospholipid is a good stabilizer in the preparation of emulsions. Currently, liposomes are used in environmentally conscious fabric processing procedures in the textile industry to encapsulate dye molecules, in order to reduce environmental pollution ; the related processing techniques have already exhibited promising results [5]. Such liposome-encapsulated dye formulations have demonstrated outstanding coloring effects on coloring protein fibers, such as wool and silk, as liposomes enabled the formulations to dissolve fast, which increased the effectiveness of the coloring processes and also improved the antistatic and antishrinkage effects of the fabrics [6,7,8]. Cholesterol (CH) is an important component of biological membranes. Due to its planar structure, cholesterol itself cannot form a bilayer, but may combine with lipids in different concentrations, including a Assessment on the Effects of Liposome-encapsulated Thioglycolic Acid on Hair Perming
