Laser hair removal works by targeting the melanin (pigment) in hair follicles, which absorbs the light energy from the laser and converts it into heat. This heat then damages the hair follicles, inhibiting or delaying future hair growth. However, the process isn't 100% effective on all hairs during one session due to the hair growth cycle.

Here are several reasons why it's important to top up your laser hair removal sessions:

1. Hair Growth Cycles: Hair grows in different cycles: anagen (active growth phase), catagen (transition phase), and telogen (resting phase). Laser hair removal is most effective during the anagen phase when the hair is actively growing, but not all hairs are in this phase at the same time. Multiple sessions are needed to catch each hair in its growth phase.

2. Variation in Hair Thickness and Color: Different hairs have different thicknesses and colors, even in the same area. Lighter or finer hair is harder for the laser to target, and may require more treatments to achieve the desired results.

3. Hormonal Changes: Hormonal changes, such as those occurring during pregnancy, menopause, or due to certain health conditions or medications, can stimulate new hair growth. Regular top-ups can help manage this new growth.

4. Maintenance: Over time, some hair follicles that were dormant or not effectively treated may start producing hair again. Regular top-up sessions can help maintain the smooth, hair-free results.

5. Individual Differences: Everyone's body responds a bit differently to laser hair removal. Some people may require more sessions than others to achieve the desired results.
