Laser Hair Removal: How It Works, How Many Sessions, and What to Expect

Who Is a Good Candidate (Including Different Skin Tones)

Laser hair removal works best when there is clear contrast between the pigment in the hair and the pigment in the surrounding skin. Historically, that meant lighter skin and darker hair produced the most predictable results. Modern laser technology has significantly expanded who can be treated effectively — but the device used and the settings selected still matter considerably by skin type.

Patients with darker complexions (Fitzpatrick skin types IV through VI) can absolutely be treated with laser hair removal, with one important caveat: the laser must be appropriate for their skin tone. Longer-wavelength devices — particularly Nd:YAG — are better suited for deeper skin tones because the longer wavelength bypasses melanin in the skin surface and targets the follicle more selectively. The InMode Triton at both RELUXE locations includes Nd:YAG as one of its three wavelengths, allowing providers to switch seamlessly to the safest setting for each patient. Our team is experienced in treating a full range of skin tones and will confirm the right approach, including performing a test spot when appropriate, before treating a full area.

Patients who tend to see the most benefit from laser hair removal are those dealing with coarse, dark hair — underarms, bikini, legs, back, and facial areas like the chin and upper lip. Very light, fine, or gray hair contains less melanin and does not respond as well to laser treatment, which is worth discussing during your consultation. Active tans and recent sun exposure in the treatment area do require you to wait before starting, as elevated surface pigment increases the risk of irritation.

How Many Sessions You Need and How They Are Spaced

Most patients require six to ten sessions to achieve significant, lasting hair reduction in a given area. The range is wide for a reason — it reflects genuine variation in how individual follicles respond, how dense the hair is, how consistently sessions are scheduled, and whether hormones influence hair growth in that area. The face and bikini line, for example, are hormonally influenced zones where follicles can be more stubborn and may require more sessions than the legs or underarms.

Session spacing follows the hair growth cycle. For most body areas, sessions are scheduled four to eight weeks apart. Going too soon means the next crop of follicles has not entered the active phase yet. Going too long means you lose momentum and allow previously dormant follicles to become active without treatment. Your provider will recommend the right interval for each area based on how your hair is cycling.

At RELUXE, we offer flexible treatment structures to fit different goals and budgets. Area packages (buy five sessions, get three free) are a popular choice for patients targeting one or two specific areas. Our Truly Unlimited package — $5,000 for 18 months of unlimited sessions across unlimited areas — is designed for patients who want comprehensive coverage without tracking individual area pricing. VIP members receive an additional discount on top of published pricing. Your provider will recommend what makes sense based on your goals during your initial consultation.

What to Expect During a Treatment Session

Each session begins with confirming the treatment area is properly prepared — skin should be shaved 12 to 24 hours before your appointment, clean, and free of lotion, deodorant, and self-tanner. Waxing, threading, or plucking must be avoided for at least four weeks before any session because those methods remove the follicle the laser needs to target.

The treatment itself involves passing the laser device over the treatment area in overlapping rows. Most patients describe the sensation as brief snaps of warmth — similar to the flick of a rubber band — with a cooling sensation from the device's built-in chilled tip between pulses. The warmth is real but short-lived. Most patients tolerate treatment well without any numbing cream, though sensitive areas like the bikini line or upper lip may call for topical numbing for patients who prefer it.

Session length varies by area. Upper lip and chin take around five minutes. Underarms are 10 to 15 minutes. Full legs can take 30 to 45 minutes. After treatment, mild redness and small follicular bumps — similar to a light sunburn — are normal and typically resolve within a few hours to one day. There is no meaningful downtime. Most patients go directly back to work or their regular schedule.

Results Timeline: What Changes and When

The shedding phase is the first visible sign that the treatment worked. Starting around seven to fourteen days after a session, treated hairs push out of the follicle and fall away. This looks like small dark pepper dots on the skin and can sometimes be mistaken for regrowth — it is the opposite. You can gently exfoliate and shave as normal during this phase.

After each session, you should see progressively less regrowth in the treated area. Many patients notice a meaningful reduction after three or four sessions — thinner hair, slower growth, and noticeably cleaner results between sessions. The full benefit of a complete series typically develops by the end of all your scheduled sessions, with some ongoing improvement as the last-treated follicles finish their cycle.

Most patients see somewhere between 70 and 90 percent reduction after completing a full series. Some follicles may eventually reactivate — particularly in hormonally sensitive areas — which is why occasional maintenance sessions once or twice a year are useful for keeping results where you want them. Results are long-lasting, and most patients find they spend a fraction of the time and money they previously spent on shaving and waxing.

Laser Hair Removal vs. Waxing and Shaving

Waxing and shaving work on the surface. They remove hair temporarily without affecting the follicle, which means full regrowth is always guaranteed. Shaving typically means daily or every-other-day maintenance for most body areas. Waxing buys two to four weeks before regrowth returns, and for many patients it comes back just as coarse and dense as before. Neither method reduces hair over time.

Laser hair removal targets the follicle itself. After a complete series, most patients see lasting reduction that requires only occasional maintenance rather than continuous effort. The time and cost math tends to favor laser for patients who have been consistently waxing or shaving high-maintenance areas for years — most find that the upfront investment in a package pays for itself within a year or two when compared to ongoing waxing costs and the time spent shaving.

Ingrown hairs are another meaningful difference. Waxing and shaving are common culprits for ingrown hairs — particularly in the bikini, underarm, and leg areas. Laser hair removal significantly reduces ingrown hair occurrence because it reduces the number of hairs that can become trapped beneath the skin surface. For patients who deal with chronic ingrowns or razor bumps, laser is often the most practical long-term solution.

The honest trade-off is the upfront investment and commitment to a full series. Laser hair removal requires multiple sessions over several months, and you will be shaving (not waxing) between appointments. For patients who are consistent and patient with the process, the cumulative results make it worthwhile. Your provider at RELUXE will give you a realistic picture of what to expect for your specific areas before you start.
