Ace the Florida Restricted Barber Exam 2026 – Snip, Style, and Shine!

Hair growth occurs primarily from the hair follicle, where the cells actively divide and generate new hair. The hair follicle is a specialized structure located beneath the skin's surface, playing a critical role in hair production. The base of the hair follicle contains a region called the hair bulb, where living cells proliferate to form the hair strand. As these cells multiply, they go through a process of keratinization, ultimately resulting in the formation of the hair shaft that extends above the skin.

Understanding this process is essential for hair care and for those pursuing a career in barbering, as it informs various treatments and techniques. The other options presented do not accurately represent how hair grows or misinterpret aspects of hair anatomy. For example, hair does not grow from the hair shaft itself, as this part is composed of dead cells. Additionally, hair does not originate from the outer skin layer or dead skin cells, making the hair follicle the primary source of growth.
