Cosmetology is a discipline that covers hairstyling, skin and nail care and chemical services. While much of what a cosmetologist offers is a hands-on, individual service, as with almost all facets of life, technology plays a role.

A computer program in a salon can aid clients when they are selecting a new hair style. The client brings in a photo of herself which is scanned into a computer. On the monitor, the cosmetologist can then show the client how she will look with an array of hairstyles and colors from which she can make her selection.

For more than a century, the “permanent wave” hair style has been popular. Over the years, a number of technological applications have been used, some seriously damaging the hair. Today, cosmetologists employ the “digital perm,” which uses chemicals without using heat styling. Such things as built-in conditioners aid stylists to give their clients hair with smooth waves or flattering curls.

Cosmetologists responsible for finger and toenail care have specialized technology to assist them. While it is still a finger-by-finger or toe-by-toe procedure, cosmetologists work in a far- more sterilized area than previously and are trained to identify nail diseases and infections. They have technically-advanced acrylic wraps and more specialized tools, too.

Skin care cosmetologists use a variety of technologies to perform such techniques as steam extraction, chemical peels and micro-dermabrasion. They also perform hair removal with warm wax.
