What is the category for products designed to restructure or change the shape of hair, skin, or nails?

The category of products designed to restructure or change the shape of hair, skin, or nails falls under chemical services. This category encompasses a variety of treatments and products, such as hair relaxers, perms, hair color, facials, and nail enhancements, which utilize chemical agents to achieve desired aesthetic results.

Chemical services are integral to the beauty and personal care industry and require specialized training to ensure safe and effective application. Understanding the chemical processes involved is crucial for practitioners to avoid adverse reactions and to provide effective treatments. This distinguishes them from other categories, such as surgical or massage services, which serve different purposes entirely and involve different techniques and products.
