True or False: Cosmetologists may practice with razor-type callus shavers.

Cosmetologists are not allowed to practice with razor-type callus shavers because these tools are considered to fall under the category of medical devices. Their use is generally restricted to licensed professionals in medical fields, such as podiatrists, who are trained to perform invasive procedures on the skin. This regulation is in place to ensure the safety and health of clients, as improper use of such tools could lead to injury or infection.

While there may be various tools available for callus removal that are designed for use by cosmetologists, a razor-type callus shaver is explicitly prohibited under Texas cosmetology laws. This ensures that all practices remain within safe and appropriate boundaries for cosmetologists and that clients receive proper care without the risks associated with more invasive techniques.
