Hair grows in cycles. At any given moment only 20-30% of hairs are in the active phase (anagen), when the light can "see" them. The rest are dormant and become vulnerable later. That is why sessions are repeated at intervals of 4-6 weeks, "switching off" new batches of follicles.
- Usually 6-8 sessions are needed for a lasting result.
- The interval is 4-6 weeks depending on the area.
- After just 2-3 sessions there is noticeably less hair and it is finer.
- After that, maintenance treatments 1-2 times a year.
