How Many Laser Hair Removal Sessions Do You Need?

Most people need 6 to 8 sessions, spaced 4 to 6 weeks apart, to get their best laser hair removal results. After that, a touch-up about once a year keeps the skin smooth.

Here is why it takes a series, and what you can expect along the way.

Hair Grows in Cycles

Each hair follicle goes through three phases:

1. Growth. The hair is attached to the root and actively growing.
2. Transition. The hair stops growing and starts to detach.
3. Rest. The old hair falls out, and the follicle waits before it grows a new one.

The laser works best on hair in the growth phase, when the hair is attached to the root. At any one time, only part of the hair in an area is in that phase. Each session treats a new group of follicles as they enter it. That is why spacing matters: the gap between sessions gives the next group time to start growing.

What Changes the Number of Sessions

• The area. Hair on the face often responds differently than hair on the legs or underarms.
• Your hair. Thick, dark hair usually responds quickly. Fine or light hair can take more sessions.
• Hormones. Hair driven by hormones, such as some facial hair, can need more sessions and more touch-ups.

At your first visit, we look at your skin and hair and tell you what to expect for your area.

What to Expect at Each Stage

After sessions 1 and 2: treated hairs fall out over one to two weeks. Regrowth is often patchy.

After sessions 3 and 4: most people see a clear drop in hair. What grows back is often finer.

After sessions 6 to 8: most treated hair is gone. Many people stop shaving the area.

Each year after: a short touch-up treats any new or returning hair.

How to Get the Best Results

• Keep your appointments on schedule. Long gaps let hair cycles drift.
• Shave before each visit, so the laser goes to the root instead of the surface hair.
• Do not wax, pluck, or thread between sessions. Those remove the root the laser needs.

Our laser hair removal packages include 6 sessions. See our laser hair removal page for details, or book online.
