There are a number of reasons why laser hair removal results aren’t always permanent. The most prominent factors include but aren’t limited to:
- Hair Type and Color: Laser hair removal works best for coarse, dark hair, but obviously not everyone has that hair color. Clients who have finer hair may require more sessions and touch ups to maintain desired results.
- Skin Tone: A lighter skin tone with darker hair color yields the best contrast for the laser, maximizing effectiveness. However, laser hair removal can be performed safely and effectively on all skin colors.
- Hormonal Fluctuations: Changes in hormone levels throughout a person's life can stimulate hair growth. Pregnancy, puberty, and certain medications are some of the most common reasons for increased hair growth, which may necessitate additional touch-up sessions after laser treatment.
