In which hair growth stage would most hair be found if a client has been tweezing weekly?

The correct answer is early anagen. In the context of hair growth cycles, anagen is the active growth phase where the hair follicles are producing hair. When a client has been tweezing weekly, it is likely that the majority of the hair they possess is still in this early anagen stage.

During this stage, hair is actively growing, and because tweezing removes the hair from the root, it may leave many hair follicles still in this growth phase, preparing to push new hair out. If the client tweezes regularly, they may be removing hairs that are already within this growth cycle, thus allowing fresh hair to emerge from the follicles.

By understanding the hair growth phases, we can see that most tweezed hair would not typically be found in telogen (the resting phase), catagen (the transitional phase), or late anagen (where follicles may start preparing to enter catagen). Therefore, identifying early anagen as the phase with the most hair makes sense, as it aligns with the hair's biological growth cycle during frequent removal practices like tweezing.
