Products and Uses Used in depilatory and hair-waving products. For hair removal and hair permanents. 

Depending on the type of waving product used, there may be several variations to the procedure outlined above. Thus, instead of wrapping with lotion, the hair is wound wet and the lotion appHed to curled hair. Some instmctions also suggest a creep stage for better tightness and durabiUty. This is simply a 30 min wait between rinsing off the lotion and appHcation of the neutralizer.

Cosmetics are natural or synthetic toiletry products that are used to maintain hygiene and include externally applied products used to enhance appearance. This class includes dental products, bath supplies (e.g., bubble baths, body washes, and bath beads), powders, lotions, lipsticks, perfumes, colognes, shampoos, depilatories, and hair coloring/waving products. Most of these products contain alcohols, aromatic hydrocarbons, perborates, and anionic and nonionic surfactants. Use of cosmetics is as old as civilization itself. Centuries ago wealthy women would apply the white lead pigment known as ceruse to their faces to appear fashionably pale - sometimes with lethal consequences. Women also used belladonna alkaloids like atropine to dilate pupils to enhance the attractiveness of the eyes in the late nineteenth century.

Microemulsions have also been investigated for the use in chemical hair treatment [14]. Permanent wave products are based on the reduction of hair keratine cystine, which weakens the protein structure and allows a manipulation of the hair shape. Savelli et al. compared the cystine reduction obtained by thioglycolic acid in water with that obtained by a microemulsion. The microemulsion is based on the anionic surfactant sodium dode-cylsulphate, the co-surfactant pentanol and dodecane as the unpolar oil component. The cysteine formation is evaluated over a time period of 5 min. The experimental data are... 

The neutralizers of hair straighteners are similar to those of permanent-waving products. The thiol-based products usually use an oxidizing system based generally on hydrogen peroxide or sodium bromate, whereas the... 

As for other reactive hair products, the primary safety concerns for permanent waves generally arise from misuse or failure to comply with the product s usage instructions. Skin irritation, hair breakage, oral toxicity, sensitization, and scarring alopecia either have been reported in the hterature or are referred to in the warning instructions for home permanent-wave products.
