When does an individual cosmetology license typically expire?

An individual cosmetology license typically expires on the last day of the licensee's birth month. This system allows for a clear and consistent renewal timeline based on the individual's personal milestone, making it easier for licensees to remember when to renew their licenses. Consequently, this aligns with many professional licensing structures, which aim to tie renewal dates to significant personal dates, allowing for individualized tracking.

The other options suggest different timing mechanisms that are less personalized and could lead to confusion regarding the expiration of licenses. For instance, tying expiration to the last day of the year issued or to a specific date in a fixed month like January does not align with the common practice of aligning renewals with personal milestones such as birthdays.
