What does a 100-hour course in nail technology include training on?

A 100-hour course in nail technology primarily focuses on developing skills specific to the care and manipulation of nails, encompassing both natural and artificial nail techniques. This type of training includes filing and shaping of fingernails, which is essential for creating aesthetically pleasing nail designs and maintaining client satisfaction.

The course also introduces students to the proper use of tools and techniques needed for manicure and pedicure services. In contrast, the other options listed do not align with the primary objectives of a nail technology course. Shampooing and haircutting relate more to cosmetology and haircutting specialties, while masque and skin treatments are generally part of skincare courses. Hair dyeing and perming techniques fall under hairdressing education. Therefore, option C is accurate because it directly addresses the specific skills taught in a nail technology course.
