Is One Session of Laser Hair Removal Worth It?

Your first laser hair removal session is a major step toward smooth, hair-free skin — but it’s just the beginning. Only getting one session of laser hair removal and stopping doesn’t make much sense. You might see some (possibly even significant) hair reduction but it’s not going to stick, and a lot of hair will likely grow back eventually. In this post, we'll explain why, and what really happens after that first appointment.

What Happens After One Session

During your session, the laser delivers heat to hair follicles in the anagen phase — the active growth stage. This causes controlled damage that inhibits future growth. However, follicles in other stages (like resting or shedding) won’t respond as well, which is why consistent sessions spaced a few weeks apart are essential for long-term reduction. Within a week or two of your first session, you might notice hair falling out in the treated area. This is called “shedding,” and it’s a sign that the laser did its job. The laser targets the root of each hair during its active growth phase, damaging the follicle and causing the hair shaft to fall out. Many clients see a visible reduction in hair growth after just one session, with some hair growing back finer and patchier coverage in the treated area. But keep in mind — not all hairs are in the same growth phase at once, so eventually, a lot of hair will grow back from hair follicles that were previously at rest. That’s why multiple sessions are key for optimal results. Even after completing a full series of laser hair removal sessions, some degree of hair regrowth over time is completely normal. Factors like hormonal changes, genetics, and the treatment area itself can all contribute to new or recurring hair growth in the years following your treatments. While the majority of follicles treated during the active growth phase are permanently damaged, others may reactivate or new follicles can develop. Laser hair removal works best on those with fair skin and dark, coarse hair — that contrast helps the laser pinpoint the pigment in the follicle more easily. Finer hair, especially on the face, might need more treatments to achieve noticeable results. And areas like the legs often respond more quickly than others due to the natural hair growth cycle. That first session is just the start of your laser hair removal journey. You’ll likely see some shedding and early signs of reduced growth, but achieving lasting results takes time and a full series of treatments. Stick with it, and you'll be amazed by the transformation.
