Unwanted Hair: Permanent Hair Reduction Options Compared

Shaving, waxing, tweezing, sugaring and depilatory creams are the everyday methods.

The American Academy of Dermatology (AAD) frames the contrast with the long-term option directly in its laser hair removal guidance — regrowth after laser treatment tends to be less, finer and lighter, unlike dermaplaning and shaving, which are temporary.

Dermaplaning, the scalpel exfoliation facial on med spa menus, sits in the temporary tier too.

Cleveland Clinic describes it as shaving away the uppermost layers of skin with a blade, used for dull skin, fine lines, mild acne scars and peach fuzz, and says any hair removal from it is only a temporary fix because the hair grows back.

The same source retires a stubborn myth: peach fuzz does not grow back thicker after you remove it — regrowing hairs can seem thicker because the blunt tip pushes through the skin surface, but they feel softer as they grow.

The long-term tier has two members.

Laser devices carry the FDA-cleared claim of permanent hair reduction, which their clearances define as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9 and 12 months after the completion of a treatment course. IPL — intense pulsed light — is broadband light rather than a laser, and it shows up in hair-removal research and clearances too, though its labels can cover fewer skin types; the device-choice section below has that detail.

Electrolysis is the other long-term method — New Hampshire's electrology law, for example, defines it as hair removal by electric current through a needle.

It is widely described as the one method that removes hair permanently regardless of color, on the idea that the current treats each follicle directly rather than working through pigment.

That description is widely repeated and unverified — the electrolysis section below takes it up.

Laser hair removal works by targeting melanin, the pigment inside the hair follicle, to damage the cells that regrow hair.

That mechanism is also its limit: white, gray and blond hair respond poorly, because there is little pigment for the laser to find.

The AAD puts the best-response profile plainly: laser hair removal works best on light skin with dark hair.

It adds that treatment can today also be done on dark skin, and on light hair with light skin, but must be done very carefully in those patients.

One area carries a standing caveat of its own: the AAD says laser hair removal is not permanent on women's faces because of hormones, and regrowth there is common.

The face gets a closer look in the area-by-area section below.

The shape of a course, briefly — our laser hair removal guide owns the session-by-session detail: the AAD expects a 10% to 25% reduction in hair after the first treatment; its FAQ gives most patients 2 to 6 treatments, usually once every 4 to 6 weeks, and says a patient may need maintenance laser treatments to keep the area free of hair; its overview says removing the hair can take 6 sessions or more.

Electrolysis is the option widely named for the hair lasers respond poorly to — white, gray and blond.

The idea behind it is mechanical: an electric current treats each follicle directly, so hair color should not matter.

That description is widely repeated, and we could not verify it — the FDA consumer page it is usually traced to had been removed from fda.gov when our research checked.

Treat it as a claim to test with a licensed electrologist, not a settled fact.

The only head-to-head measurement in our research vault is small and old: a 2000 study gave 12 patients alexandrite laser treatment on one armpit and electrolysis on the other.

Six months later, the laser side had cleared 74% of hairs against 35% on the electrolysis side, and the authors found the laser more expensive per session but about 60 times faster and less painful.

One trial, one body area, 12 people — read it as a data point, not a verdict.

Licensing matters here too: New Hampshire, for example, licenses electrologists for needle electrolysis — hair removal by electric current through a needle — and that license does not cover laser or light-based hair removal.

Ask any electrologist you are considering what license they hold and what it covers in your state.

The face carries the strongest caveat.

The AAD says laser hair removal is not permanent on women's faces because of hormones, and regrowth there is common.

The trial data point the same way: a 2022 systematic review of 5 randomized trials found long-term hair reduction was greatest on the legs and lowest on the face.

One face-specific warning signal is worth knowing before you book.

A 2025 prospective study of women having alexandrite laser treatment for facial hair found paradoxical hypertrichosis — new or thicker hair growth after laser or IPL hair removal — in 16.2% of patients, with higher rates linked to PCOS, irregular periods, a family history of hirsutism, Fitzpatrick types III to IV and lack of regular sunblock.

A 2021 meta-analysis of 22 studies pooled the rate at 3%, mostly on the face or neck.

Read the 16.2% as what one single-center study found in its patients, not a general rate — and as a question to ask about your own risk factors.

For the beard area, one cleared signal: the 1064-nm wavelength of the Candela GentleMax Pro Plus is cleared for pseudofolliculitis barbae — razor bumps — alongside that device's hair-reduction clearance.

That is a clearance for one device and wavelength, not a statement that every clinic's laser treats razor bumps.

Session time also follows the area: the AAD says an upper lip takes minutes, while large areas like the back or legs can take more than an hour.

Underarms are the one area in this comparison with head-to-head numbers — the 2000 split-axilla study in the electrolysis section above ran there, one armpit treated by laser and one by electrolysis.

The bikini area has its own page — what a Brazilian covers, sessions and cost are on our brazilian laser hair removal guide.

Skin tone in dermatology runs on the Fitzpatrick scale, developed by Thomas Fitzpatrick in 1975, which classifies skin by its reaction to sun: type I always burns and never tans; type II usually burns, with minimal tanning; type III occasionally burns and usually tans; type IV rarely burns and always tans well; type V very rarely burns and tans very easily; type VI never burns.

Two cautions travel with the scale: it was built to dose UVA phototherapy for people with white skin, and dermatologists have criticized its "never burns" descriptions for types V and VI as inaccurate — it describes sun reaction, not race.

Device clearances name their skin-type coverage explicitly.

The Candela GentleMax Pro Plus, a 755-nm alexandrite and 1064-nm Nd:YAG system, is cleared for hair reduction on all skin types, Fitzpatrick I to VI, including tanned skin.

Cleared is the operative word: hair-removal lasers are 510(k)-cleared devices, not FDA-approved ones, and their cleared claim is the reduction wording above.

A label that covers all six skin types is not a promise of the same result in each of them — the AAD's "very carefully" caveat for dark skin and light hair stands.

IPL is the comparison point, and it is not a laser: IPL devices use broadband light, and their hair-removal clearances can run narrower than lasers'.

The Stellar M22 IPL, for example, claims permanent hair reduction in Fitzpatrick types I to V — not VI — unlike several lasers whose clearances list types I to VI.

The risk profile is worth reading before you choose a device or a clinic.

The AAD says common laser hair removal side effects — discomfort, swelling and redness — are minor and last 1 to 3 days, while rarer ones include blistering, cold sore outbreaks, infection, scarring, and lightening or darkening of the skin that can occasionally be permanent.

Treated skin must be kept out of the sun and tanning beds.

What does laser hair removal cost, and how is it priced?

Two chains publish numbers.

LaserAway's pricing page, read in October 2026, listed laser hair removal at $99 to $649 per treatment depending on area — "We price by treatment area, available as single sessions or packages of 3, 8, or 10" — with prices that may vary by location.

Sev Skin says its laser hair removal memberships start at $15 per month and single sessions start at $29, with prices varying by treatment, area and location.

Both sets are chain-published prices, and both chains say their prices vary by location — neither is a national average or a quote for your local practice.

Insurance does not cover laser hair removal, in the AAD's flat statement.

The tax side lines up behind it: IRS Publication 502 (2025) says you generally cannot include cosmetic procedures in medical expenses — it names hair removal and electrolysis among its examples — unless they are needed to fix a deformity from a congenital abnormality, an accident or trauma, or a disfiguring disease, which is why cosmetic hair removal is generally not HSA or FSA eligible either.

Does the course cost less than years of waxing?

We found no rigorous study comparing the lifetime cost of laser treatment with ongoing waxing, so a claim that laser "pays for itself" against a waxing habit is marketing we cannot verify from research, not a research finding.

We also could not confirm a national per-area price for laser hair removal — we found no tier-1 or tier-2 source that publishes one.

The workable method is arithmetic on your own numbers: a written quote stating the areas, the number of sessions assumed and the cost of maintenance sessions, set against what you spend on hair removal now.

The fuller cost breakdown is in our laser hair removal guide.

MedSpaStandard's med spa directory and its treatment-by-city listings are being built and are not live yet, so this page cannot point you to a specific practice.

What travels with you is the vetting — the same vetting our skin and body concerns hub builds into every page in this series.

The American Academy of Dermatology suggests asking, before any cosmetic procedure:

• Are you board-certified?
• How many times have you done this exact procedure?
• How often do you treat patients with my skin tone and type?
• What results can I realistically expect — with before-and-after photos of people with a similar skin tone?
• What are the risks, recovery time, number of treatments and cost?

There is no federal law that defines a med spa: whether one is regulated as a medical practice, and who may own it, is determined by each state's medical-practice, nursing and corporate-practice rules, as AmSpa, a med spa trade association, explains.

License scopes add a second layer, and three states show how much they differ.

California's esthetician license does not include hair removal by lasers or light waves.

Kansas requires the delegating physician to be physically present — or immediately available, within five minutes, with a signed written protocol — when class III/IV lasers or IPL devices substantially equivalent to laser surgical devices are used.

And New Hampshire licenses electrologists only for needle electrolysis — hair removal by electric current through a needle — a license that does not cover laser or light-based hair removal.

Ask a practice you are considering who will perform your treatment, what license that person holds, and how your state's rules apply to their setup.

Our med spa laws by state guide and 10-point checklist for choosing a med spa go deeper.

One red flag is specific to this topic.

A clinic that promises permanent removal is promising more than the cleared wording supports: the FDA-cleared claim is permanent hair reduction, counted at 6, 9 and 12 months.

A practice that quotes the claim accurately has already told you something about how it runs.
