Why do laser treatments target hair during the Anagen phase?

Laser treatments target hair during the Anagen phase because this is when the hair is actively growing and contains the most pigment. The presence of melanin in the hair follicle absorbs the laser's energy, which is converted to heat. This heat effectively damages the hair follicle, inhibiting future hair growth. Since the Anagen phase is characterized by the strongest connection between the hair and the follicle, it makes it the most effective time for laser treatment.

The other options do not accurately capture the primary reason laser treatments are effective during this phase. While the visibility of hair and its softness might play a role in the treatment experience, it is the pigmentation and active growth that are crucial for achieving optimal results. This phase represents a unique opportunity where the laser can effectively target and destroy the hair follicle while minimizing damage to the surrounding skin.
