Does Laser Hair Removal Get Rid of Hair Permanently?

If you’re tired of constantly shaving, plucking or waxing unwanted hair, you may have considered laser hair removal (LHR) as a more long-term solution. But does this popular cosmetic treatment actually eliminate hair forever? In this post, we’ll explore the science behind LHR and explore just how permanent its results can be.

How Laser Hair Removal Works

Let’s start with the basics of how LHR works to reduce hair growth. The treatment uses concentrated beams of light (lasers) that selectively target hair follicles’ pigment (melanin). The melanin absorbs the laser light, damaging the follicle and inhibiting future hair growth.

Lasers can only effectively target hair in the anagen phase. At any given time, a certain percentage of your hair is in this phase, while the rest is either in the transitional catagen phase or the resting telogen phase. Since each laser treatment can only affect a percentage of hair follicles, multiple sessions are needed to achieve optimal hair reduction.

Factors Affecting Laser Hair Removal Results

1. Hair Color and Skin Tone

Most work best on dark hair with light skin since the laser targets the pigment contrast between the hair and the skin. If there’s a significant difference, the laser can more precisely focus on the hair follicle without damaging the surrounding skin.
However, advances in laser technology have made the treatment safer and more effective for people with darker skin tones or lighter hair colors. For example, the Nd:YAG laser has a longer wavelength that can safely treat darker skin types. Choosing an experienced provider who can select the appropriate laser for your skin tone and hair type is crucial.

2. Hormones

Hormonal changes can stimulate brand-new hair growth, even after a full series of laser hair removal treatments. Conditions like PCOS that can cause excessive hair growth may require ongoing LHR maintenance or hormonal medications to manage symptoms.

3. Treatment Consistency

For optimal results, it’s essential to stick to the treatment schedule recommended by your provider. Most people need four to eight sessions, spaced four to eight weeks apart, to target hair in different growth cycles. Skipping or stretching out treatments can prolong the process and may yield less dramatic results.

4. Maintenance Sessions

It’s true that laser hair removal significantly reduces hair growth. However, some people may need periodic maintenance sessions to keep the area hair-free. The frequency of these touch-ups varies from person to person but is typically once or twice a year.

So, Is Laser Hair Removal Really Permanent?

Laser hair removal is often called a permanent hair reduction solution, but it’s not a one-and-done deal for most people. It usually doesn’t result in complete, permanent hair removal.

According to the American Academy of Dermatology, most people experience a 70-90% reduction in hair after a full series of treatments. The remaining hair is often finer, lighter and less noticeable than before. However, some people may see regrowth over time, especially if hormonal changes stimulate new hair growth. The U.S. FDA regulates laser devices used for hair removal. This means that manufacturers are not allowed to claim that their devices result in permanent hair removal, only permanent hair reduction. This distinction underscores the reality that while LHR can dramatically reduce hair growth, it doesn’t guarantee a forever hair-free outcome.

That said, most people find the long-lasting laser hair removal results well worth it. The treatment can save countless hours and dollars that would be spent on multiple temporary hair removal methods like shaving or waxing. Plus, the boosted confidence that comes with smooth, hair-free skin is priceless for many.

Comparison to Other Hair Removal Methods

When it comes to hair removal, there are several methods to choose from, each with its advantages and drawbacks. Let’s take a closer look at other popular options:


Shaving is by far the most common method of hair removal for all genders. It’s affordable, quick, easy and can be done at home. However, the results are short-lived. Shaving can also lead to ingrown hairs, razor burns and stubble regrowth that feels scratchy or itchy. In contrast, laser hair removal offers a significant reduction in hair growth after a series of treatments with long-lasting results.


This involves applying a specially formulated hot wax to the skin and then pulling it off, removing the hair at the root. This method can provide smooth results that last for several weeks. However, waxing can be painful, especially in sensitive areas, and can cause skin irritation or allergic reactions. It also requires hair to be a certain length for effective removal while laser hair removal can be performed on hair as short as a grain of rice and is generally less painful than waxing.


Threading is a precise technique using a thin thread to pull out a line of individual hairs in a sweeping motion. It’s often used to shape eyebrows or remove facial hair. While threading can provide clean, defined results, it can be time-consuming and requires regular maintenance. Laser hair removal treats larger areas more efficiently, offering lasting results.


Electrolysis is the only FDA-approved permanent hair removal method. It involves inserting a fine needle into each hair follicle that delivers an electric current to destroy the growth center. While electrolysis can be effective, it’s a tedious, time-consuming process that requires multiple sessions. It can also be painful for many. Laser hair removal, while not considered completely permanent, can achieve long-term hair reduction more efficiently and with less discomfort.
