Laser Hair Removal Demystified: What You Need to Know Before Your First Session | Extrapolate (2024)

The hair has the potential to grow back, especially in cases where the follicle is only damaged rather than removed during the process of laser hair removal.

Consequently, numerous medical professionals currently prefer to label laser hair removal as an approach for long-term hair reduction, rather than claiming it as a completely permanent solution

Discover the intricacies of this process, including its mechanism, duration of effectiveness, and the financial aspects involved in laser hair removal treatments.

Let’s understand everything about them.

According to Extrapolate, the global laser hair removal market is expected to register a valuation of $2784.5 million by 2030. This explains the immense potential of the industry. People are increasingly favoring this method as it is a quick and permanent solution for hair removal.

That brings us to the different types of hair removal techniques: laser and electrolysis.

Electrolysis is another type of hair removal, but it is considered more permanent. A probe is inserted into each hair follicle, delivering an electric current and inhibiting hair growth. Unlike laser hair removal, it works on all hair but takes longer and can be more expensive than conventional methods. Hair removal can be an important part of transitioning for members of the trans and gender-expansive communities and can help with feelings of dysphoria or unease.

Advantages of Laser Hair Removal

Laser technology offers a valuable solution for eliminating undesired hair in various body areas such as the face, legs, chin, back, arms, underarms, and bikini lines. It's important to note that there are certain limitations when it comes to laser treatment, as it cannot be performed on the eyelids or surrounding areas, as well as on tattooed skin.

Benefits of laser hair removal include:

  • Improved Focus: Lasers possess the ability to precisely focus on dark, thick strands of hair while ensuring that the surrounding skin remains unharmed.
  • Speed: Every pulse of the laser works in a fraction of a second and can treat many hairs at the same time.
  • Precise Removal: The laser treats an area that is approximately the size of a quarter in a second. Small areas like the upper lip get treated in under a minute while larger areas, such as legs or the back, may take up to an hour.

In terms of hair loss, it is common for patients to experience permanent hair loss following an average of three to seven treatment sessions.

Is Laser Hair Removal Permanent?

Hair removal from a damaged hair follicle results in permanent hair loss. Nevertheless, individuals undergoing hair removal treatments should anticipate the regrowth of some hair in the treated area.

With repeated treatments, it is feasible to retreat the area to minimize the regrowth of hair. In certain instances, it might even be feasible to remove all hair.

The regrowth of hair is influenced by various factors, such as the characteristics of the newly grown hair and the proficiency of the individual involved in the hair removal process.

When hair regrows, many individuals discover that it appears lighter and less conspicuous compared to its previous state. This occurrence can be attributed to the laser's ability to potentially inflict damage on the hair follicle, even if it does not eliminate it.

When a hair follicle is damaged but not destroyed, it has the potential to regenerate the hair over time. It is challenging to eliminate every single hair follicle, which means that most individuals will experience some degree of hair regrowth.

When hair grows back, multiple treatments may be necessary to remove all of the hair, highlighting the possibility of re-treatment for individuals seeking complete hair removal.

In certain instances, there might arise situations where one's hair is either excessively light, remarkably short, or partially immune to typical treatment approaches. When faced with such circ*mstances, individuals may opt for alternative techniques of hair removal, one of which is the manual removal of stray hairs through the process of plucking.

Hair removal is most effective on individuals who have fair skin and dark hair. This is due to the contrast in pigmentation, which facilitates the laser's ability to precisely target the hair, penetrate the follicle, and ultimately eliminate it.

Individuals with a darker complexion or lighter hair color may require a greater number of laser hair removal treatment sessions when compared to others. They may also experience a higher rate of hair regrowth.

To achieve permanent hair removal, the technician needs to have a deep understanding of hair-targeting techniques and the appropriate selection of laser types. A study conducted in 2016 and published as a trusted source revealed that lasers emitting longer wavelengths yield optimal results when treating individuals with dark skin tones.

Some potential adverse effects and hazards may arise as a result of certain practices

While undergoing treatment, certain individuals may encounter sensations such as burning, stinging, or general discomfort. To alleviate these effects, many professionals in the field choose to administer a numbing cream to the specific area being treated. Nonetheless, it is important to acknowledge that there is a possibility of allergic reactions or skin irritations arising as a result of the numbing cream application.

The occurrence of minor side effects is prevalent and typically includes:

The modifications in the skin's pigmentation, specifically in individuals with darker complexions, often exhibit temporary occurrences.

Skin blistering or the formation of crust on the skin is a common condition that can

Irritation resulting from hair removal has the potential to result in scarring. Additionally, damaged skin is susceptible to becoming infected. While skin infections are uncommon, there is a risk of them spreading and becoming life-threatening.

Sun exposure has the potential to cause skin irritation, thereby elevating the chances of developing blisters and scars.

If an individual encounters severe pain, a high body temperature, the formation of crusts, blisters, or any other indications of skin damage or infection, it is imperative for them to promptly seek medical assistance.


Laser hair removal offers long-lasting effects and eliminates the need for frequent shaving, waxing, or plucking thanks to its capacity to target and kill hair follicles. The advantages of smoother, hair-free skin make it a popular option for people wishing to streamline their beauty routine, even though it may take several sessions to obtain the desired results. This ground-breaking industry has revolutionized the field of hair removal and is said to be safe and suited for a variety of skin types, enabling people to confidently embrace a hair-free lifestyle.
