What does 'hair depth' refer to in electrolysis?

'Hair depth' in electrolysis specifically refers to the distance from the surface of the epidermis to the bottom of the hair bulb. This concept is crucial in the electrolysis process because understanding the depth of hair helps technicians determine how effectively to target the hair follicles for permanent hair removal.

The hair bulb is the part of the hair follicle where hair growth occurs, and knowing the depth allows the practitioner to select the appropriate method and settings for electrolysis, ensuring that the current effectively reaches the bulb to destroy the growth cells. Each individual hair may have different depths based on various factors such as the individual's hair type and skin characteristics, making this knowledge essential for effective treatment.
