In electrolysis, which area must be targeted to effectively kill the hair follicle?

To effectively kill the hair follicle during electrolysis, the targeted area is the hair bulb. The hair bulb is located at the base of the hair follicle and contains the actively growing cells that contribute to hair production. In electrolysis, a fine probe is inserted into the hair follicle where an electric current is delivered. This current specifically targets the hair bulb, where it effectively destroys the cells responsible for hair growth.

By targeting the hair bulb, electrolysis interrupts the hair growth cycle and prevents future hair from emerging. This makes it a critical focus for achieving permanent hair removal. The other areas like the hair shaft, skin surface, and hair follicle opening do not contain the vital cells necessary for hair production, which is why they are not primary targets in the electrolysis process.
