Sessions

How many laser hair removal sessions it takes before hair growth slows

The short answer

No single number fits everyone, and Rewind publishes none for its hair removal menu: your count is confirmed at consultation. What the clinic does publish is the unit it plans in, a course of five sessions per field. Published trials used courses of three to eight sessions, spaced roughly four to six weeks apart, and even after a full course they report a reduction in hair count. None of them describes hair that stops growing altogether.

Session counts and intervals quoted here come from the protocols of the studies cited below. They describe research settings; your own plan is set by the doctor after examining the field.

The reason for a course is the hair cycle. At any moment, part of the hair in a field is growing, part is regressing and part is resting. The laser damages follicles that are actively growing, so each visit reaches one share of the field and leaves the rest for later. Spacing the visits lets a new share enter the growth phase before the next session.

Body site matters a great deal. A 2022 systematic review of long-term hair reduction found that growth cycles differ, around six months on the face, seven in the underarm and a year on the leg, and that long-term reduction was greatest on leg hair and smallest on facial hair. A beard line and a calf can need quite different plans.

Factors

What sets the count

Four things that decide how many laser hair removal sessions you need

The doctor weighs four factors when estimating a course for your field. None of them can be judged reliably from a photograph sent before the trip.

factor 01
Hair colour
Dark hair holds the pigment the laser targets. Grey, white, red or fine blond hair responds poorly however many sessions are booked.
factor 02
Body site
Facial hair has shown the smallest long-term reduction in trials and leg hair the largest, so a facial field can need more visits for a similar change.
factor 03
Hormones
Growth driven by hormones, as with some facial hair in women, tends to return sooner and changes how a course is planned.
factor 04
Skin tone
Deeper skin tones are treated at settings chosen for safety, and the plan allows for that. Trials in skin types IV to VI used courses of five sessions.

The course of five on the sheet is a planning unit and a price. Five visits may be enough for some fields and some patients, and more may be needed for others; that is confirmed at consultation and reviewed as the course goes on.

Cycle

Spacing

How laser hair removal sessions are spaced, and why the interval matters

Spacing is where many courses go wrong. Visits placed too close together meet the same growing follicles twice, and visits placed far apart simply stretch the course out.

01Weeks

Trials spaced sessions four to six weeks apart

A 2004 study of a 1064 nm laser across all skin types gave three treatments at four- to six-week intervals. A 2012 randomised trial in darker skin used five sessions at four- to six-week intervals, and a 2022 comparison of 755 nm and 1064 nm lasers used five sessions a month apart.

02Site

Faster-cycling fields may come round sooner

The face cycles faster than the leg, so the interval set for an upper lip may differ from the one set for a thigh. Your own spacing is decided at the clinic for each field.

03Result

Reduction is measured months after the last session

Trials judge results well after a course ends. In the 2004 study, hair counts six months after three treatments were 41 to 46 percent lower on the face and 48 to 53 percent lower on the body. In the 2012 trial, the Nd:YAG side showed a 79.4 percent fall in hair count six months after the final session.

04Upkeep

Some regrowth after a course is expected

Long-term reduction in the 2022 review ranged widely between devices and sites, from about 30 percent to about 84 percent. In the 2022 comparison, treated hair also became thinner. Occasional maintenance visits are how regrowth is usually handled.

Planning

How Rewind plans a laser hair removal course around trips to Korea

Most international patients cannot come to Gangnam every four to six weeks. The plan has to fit the travel as well as the hair.

01Realism

The count is estimated before a course is sold

The doctor looks at the field, the hair and the skin, and says how many visits are realistic before you buy one visit or five. If the hair is too fair to respond, that is said at the start.

02Two trips

Two trips usually mean two sessions of a longer course

Each stay in Seoul can hold one session per field, because a second session a few days later would reach the same follicles again. Across two trips that makes two sessions, so whether a course of five bought in Seoul suits you depends on how often you expect to return.

03Terms

Ask how long a course stays valid before you buy

Whether unused sessions in a course of five can be carried over to a later trip is a question to settle before paying. The answer depends on the terms that apply when you buy.

The first visit includes the consultation that sets the plan. Later visits start with a look at how the field responded last time: how much hair has returned, whether the skin reacted, and whether you have tanned or waxed since. Settings are adjusted from there, eyewear goes on for everyone in the room, and the field is treated. Sessions take place on the fourth and fifth floors of the Richro Building in Gangnam, Seoul, by appointment; the clinic is open Monday, Tuesday, Wednesday and Friday 10:00 to 19:00, and Saturday 10:00 to 16:00.

Bring notes if you have had laser hair removal with a previous provider: which area, roughly how many sessions, and when the last one took place. Earlier treatment changes where a new course starts, and the doctor can only work from what you share.

Rates

Pricing

Laser hair removal session pricing: one visit against a course of five

Because the sheet sells every field in two units, the session question and the price question are linked. The rows below show both units for three fields.

Underarm, women · one visitSingle session
₩50,000
Underarm, women · course of fiveFive sessions bought together
₩200,000
Calf, women · one visitSingle session
₩100,000
Calf, women · course of fiveFive sessions bought together
₩400,000
Upper lip, men · one visitSingle session
₩70,000
Upper lip, men · course of fiveFive sessions bought together
₩300,000

All rates are before VAT. For the underarm and calf in the women's column, the course of five costs the same as four single visits; for the men's upper lip, the course is set slightly above four visits. A course only saves money if all five sessions are used.

Fit

Shorter or longer

Who can expect a shorter laser hair removal course, and who a longer one

Often fewer sessions

  • Dark hair in lighter skin, the strongest contrast for the laser
  • Leg fields, where trials found the largest long-term reductions
  • No recent waxing or plucking, so every root is in place
  • Visits kept at the interval the doctor sets

Often more sessions, or not worth starting

  • Facial hair, especially where hormones drive growth
  • Fine, fair or grey hair, which may not respond at all
  • Long gaps between visits because of travel
  • A tan at the time of a planned session, which can mean postponing
  • Pregnancy, broken skin or infection in the field, which defer treatment
After

Aftercare

Between laser hair removal sessions: aftercare that protects the next visit

After each session, Rewind's laser instructions apply: some redness right afterwards is possible, sauna, jjimjilbang and sweaty exercise are put off, massage and strong friction are kept away from the field, and sunscreen is worn outside. Between sessions, a few further habits keep the course on track.

After each session
Let redness settle
Pink, warm skin is a common reaction and fades by itself. Keep heat, sweat and rubbing away from the field that day.
The weeks after
Shedding can look like regrowth
Treated hairs can take a while to fall out, which may look as though the laser has not worked. Wait for the doctor's assessment at the next visit.
Throughout
Razor, never wax
Shaving keeps the root in place for the next session; waxing, threading and plucking remove it. A 2023 study asked participants to stop those epilation methods four weeks before treatment.
Before returning
Stay out of the sun
A tan between sessions can mean lower settings or a postponed visit. Sunscreen on exposed fields protects the plan as much as the skin.

Each session carries the same risks as the first: redness and swelling, occasional folliculitis, blistering or superficial burns (more likely on tanned skin), and temporary darkening or lightening of the skin. The 2004 study reported mild to moderate pain, short-term redness and rare temporary pigment change without scarring. Paradoxical growth of finer hair near a treated area is uncommon. Report blistering or increasing pain promptly.

Questions

Laser hair removal sessions: questions about count and timing

How many sessions until hair stops growing?
Hair rarely stops altogether; trials measure reduction. Rewind's sheet plans in courses of five, and your own number is confirmed at consultation. Across the studies cited here, protocols ran from three to eight visits, and a 2022 review found long-term reduction ranging from about 30 to 84 percent depending on laser and body site.
How many weeks apart should sessions be?
In the studies cited on this page, sessions were spaced four to six weeks apart or monthly, and one protocol used six weeks. Your own interval is set by the doctor for each field, since facial hair cycles faster than leg hair.
Can a course be completed across two trips to Korea?
Two trips allow two sessions per field, because a second session within the same stay would come too soon. A course of five therefore needs more visits than two trips provide. Discuss your travel pattern at consultation before choosing between single visits and a course.
Why is facial hair slower to respond?
A 2022 review found the smallest long-term reductions on facial hair, which has a shorter growth cycle of around six months, and the largest on leg hair, with a cycle of about a year. Hormonal influence on facial hair can also bring regrowth sooner.
Does a darker skin tone mean more sessions?
It can mean more cautious settings. Trials in skin types IV to VI used five sessions and reported significant reductions with both 755 nm and 1064 nm lasers. The Clarity platform carries both wavelengths, and the doctor chooses between them for your skin.
I have had laser hair removal before. Do I start again?
Not necessarily. Tell the doctor roughly when your earlier sessions took place, whether with a previous provider or at Rewind, and how the hair responded. The new course is then planned from the current state of the field.
What if I miss a planned session?
Sessions already done still count, but a long gap means the next visit meets a new mix of growing and resting follicles. Book the next session when you can and mention the gap. Whether unused sessions in a course carry over is worth asking before you buy.
Is one session worth it on a short trip?
One session reaches only the follicles that are growing that day, so expect partial, temporary thinning. It can make sense as a start if you will return, or to see how your skin responds to the laser. The single-visit rate for each field is in the pricing section.

Scientific evidence

Laser hair removal session counts in the published trials

The session numbers and intervals on this page are taken from these five papers: four clinical studies whose protocols ran from three to eight sessions, and one systematic review of long-term reduction by body site. They were chosen because they report how courses were structured, and each was run by an independent research group. None involved Rewind Plastic Surgery, and none predicts the number of sessions a particular patient will need.
