In which phase of hair growth is electrolysis most successful?

Electrolysis is most successful during the anagen phase of hair growth because, in this phase, the hair is actively growing and is firmly rooted in the follicle. This is when the hair is most susceptible to the effects of electrolysis, which involves the delivery of an electrical current to destroy the hair follicle's ability to produce hair. Since the hair is still connected to its blood supply and other growth factors, the electrolysis treatment can effectively target and eliminate the hair follicle at its most vigorous stage.

In contrast, during the catagen phase, the hair growth slows, and the follicle begins to shrink, making it less effective for electrolysis as the hair is not actively growing. The telogen phase is considered the resting phase where hair is not growing, and it can be shed or fall out; targeting hair in this phase is less effective for electrolysis since the hair has detached from the follicle. "Yin phase" is not a recognized stage of hair growth in connection with electrolysis or any standard biological hair growth cycles. Therefore, the anagen phase remains the most effective time for electrolysis treatments.
