Is laser hair removal actually permanent?

If you've been tempted by the promise of smooth, hair-free skin forever, you're not alone!

Laser hair removal has been marketed as a “permanent solution” to shaving, waxing, and all the fuss. But is that actually true?

Let’s break down what laser hair removal really does—and doesn’t do—so you can make the best choice for your skin and goals.

What laser hair removal actually does

Laser hair removal is one of the most popular cosmetic treatments in the world. And it’s easy to see why. By targeting the hair follicle with concentrated light (which turns into heat), the laser disables future growth. And over time, that can lead to seriously smooth skin.

But here’s the honest truth: “permanent” doesn’t mean what you think it means.

While laser hair removal offers sincerely long-lasting results, it’s not a one-and-done deal…and it’s rarely 100% permanent for life.

So... is it permanent?

The answer is: it’s semi-permanent. Anyone telling you otherwise is not giving you the full picture.

You see, most of our clients see a major reduction in hair after a full treatment series (usually 6–8 sessions), with some areas stopping hair growth entirely. Others might need occasional maintenance sessions every year or so to keep regrowth minimal.

That’s because hair grows in cycles, sort of like how those of us in New England or seasonal regions experience the change in leaves (still with us?? Ha!)

Lasers can only treat follicles that are actively growing. Multiple sessions ensure we catch more of those active hairs over time. Any regrowth is often finer, lighter, and more sparse than before.

How long do results last?

After completing your sessions (remember a full series often ranges between 6 to 8 individual treatments), most clients stay hair-free in treated areas for months to years. The longevity depends on a few key factors:

  • Your skin and hair type
  • The area treated
  • Hormones (hi, aging and pregnancy!)
  • Your commitment to the treatment plan

After that, we typically recommend maintenance treatments 1–2 times per year to help you stay smooth in the long term. Think of it as the occasional refresh, kind of like getting your brows touched up or your roots done.

Is laser hair removal worth it?

If you’re spending time and money on razors, waxing, sugaring, or endless plucking... laser is 100% worth it. We mean that. Between waking up early to walk the dog, racing to drop the kids off at school, or one Zoom meeting after another, it can be hard to reserve the time for all the above.

Which is why laser hair removal is so beloved by clients. 

  • You save time (no more shaving every week)
  • You avoid ingrowns and irritation
  • You feel more confident in your skin
  • You actually enjoy your self-care routine

Remember, laser hair removal is safe, fast, and non-invasive—with minimal downtime and long-term payoff.

What systems med spas use for hair removal

At Siana, we use the Clarity II Laser System. It’s a state-of-the-art device that combines Alexandrite and Nd:YAG wavelengths. Say, what?? We know, there’s a lot of lingo when it comes to medical devices. 

Here’s what it means for you:

  • We can treat all skin tones safely (our medical director is a pro!)
  • We get better results for coarse and fine hair
  • Sessions are quicker and more comfortable
  • There’s built-in cooling (yes, please)

At each of your treatment sesions, we’ll tailor your service to your skin tone, hair type, and goals (even as they change over time). Best news of all, you’ll always be treated by experienced professionals under the supervision of our medical director, Dr. Howard Kesselman.

So... is laster hair removal right for you?

For most folks it’s an easy “yes!” For others, laser hair removal works especially well if:

  • You have dark, coarse hair (light hair doesn’t absorb laser energy as well)
  • You’re tired of ingrowns, bumps, or stubble
  • You’re ready for smoother skin without the hassle
  • You’re okay committing to a treatment plan for long-term gain

It may not be a great fit if you have certain medical conditions. That’s why we always start with a consult to ensure each service is aligned not only with your goals but also with your physical chemistry.
