Laser is cleared for permanent hair reduction, not permanent removal — and the difference is the single most misunderstood thing in this industry.
Laser destroys treated follicles permanently, but no single course removes every follicle forever. Expect a large permanent reduction after a full course, plus occasional maintenance.

The wording matters because it is regulated. Laser devices are cleared for permanent hair reduction: a lasting decrease in the number of hairs regrowing after a treatment course. Electrolysis, which destroys follicles one at a time with an electric current, is the only method described as permanent hair removal.
In practice, a completed laser course leaves most people with a dramatic and lasting reduction — sparse, finer, lighter hair rather than a completely bare area forever. Any clinic promising you will never see another hair is overselling.
Laser only affects follicles that are in their active growth phase at the moment of treatment, which is why sessions are spaced weeks apart. Follicles dormant during your whole course are never treated, and they can activate later.
Hormones are the other driver. Polycystic ovary syndrome, thyroid dysfunction and other endocrine conditions continuously stimulate new terminal hair, particularly on the chin, jawline, chest and abdomen. Treating the hair without investigating the hormone picture means chasing regrowth indefinitely.
Because we run a primary care practice on the same block, that workup happens in-house with lab work and hormone testing rather than a referral elsewhere.
After a full course, most patients go long stretches with nothing to treat, then come in for a single maintenance session when a few hairs reappear. Coarse dark hair on lighter skin tends to hold clearance longest. Fine, light and hormonally driven hair needs more upkeep.
Areas differ too: underarms and bikini lines usually hold very well, while faces — especially hormonally influenced chin and jawline hair — are the most maintenance-heavy area on the body.

Grey, white, red and very fine blond hair lacks the pigment the laser targets, so results are unreliable regardless of device or session count. Electrolysis is the honest recommendation there.
Active infection or inflammation in the treatment area, recent sun exposure or tanning, isotretinoin use, and certain photosensitising medications including doxycycline all require a delay. Pregnancy is a reason to wait.
Medium and darker skin types are treatable with the right wavelength and settings, but the wrong device risks burns and permanent pigment change. Ask specifically what will be used on your skin.
Follicles the laser destroys are gone permanently, but a course does not treat every follicle, so laser is cleared for permanent hair reduction rather than permanent removal. Most patients keep a large lasting reduction with occasional maintenance.
After a completed course, many people go months to years with little regrowth. Hormonally driven facial hair generally needs more frequent maintenance than body areas.
Electrolysis is the method described as permanent hair removal, because it destroys individual follicles regardless of pigment. It is slower and better suited to small areas and to light or grey hair.
