How Long Does Laser Hair Removal Last: Preparation & Process

Unwanted hair can be a persistent issue for many, and traditional hair removal methods like shaving, waxing, and epilation often provide only temporary relief.

One popular alternative is laser hair removal, which offers longer-lasting results by targeting hair follicles.

But how long does laser hair removal last?

In this article, we’ll explore the factors influencing the longevity of laser hair removal results, compare them to other hair removal methods, and provide tips on maximising the benefits of the treatment.


What Is Laser Hair Removal?

How Long Does Laser Hair Removal Last

Laser hair removal uses a focused light beam to target and destroy hair follicles, effectively inhibiting future hair growth. This non-invasive procedure is popular for those looking to remove unwanted hair from the underarms, face, bikini line, legs, upper lip, and other body parts.

Several laser technologies are available, each with advantages and suitability depending on factors such as skin tone and hair colour.


Factors Affecting The Longevity Of Laser Hair Removal Results

The duration of results from laser hair removal can vary greatly depending on several factors:


Hair Colour And Texture

Those with darker, coarser hair will find laser hair removal the most effective, as the laser targets the pigment in the hair. Lighter hair colours, such as blonde or grey, may require more sessions or may not respond as well to the treatment.


Skin Tone

The contrast between hair colour and skin tone can impact the treatment’s success. A higher contrast, such as dark hair on light skin, typically yields better results. In contrast, individuals with darker skin tones may require specialised laser treatment to avoid potential skin damage.


Hormonal Factors

Hormonal imbalances (like polycystic ovary syndrome (PCOS) for women) can cause increased hair growth and may impact the effectiveness of laser hair removal. In such cases, additional sessions or maintenance treatments might be necessary.


Maintenance And Follow-Up Treatments

Laser hair removal targets the hair’s active growth phase. As not all hair is in this stage simultaneously, multiple sessions are required for optimal results. Additionally, maintenance laser treatments may be needed to manage any future hair growth.


Expected Results And Timeline


Hair Shedding

After a laser hair removal session, treated hair will typically begin to shed within two to three weeks. During this time, it might appear as though the hair is still growing, but it’s being pushed out of the follicle.


Skin Reactions

Mild redness, swelling, or irritation may occur after the treatment, but these side effects usually disappear within several hours to a few days.


Long-Term Results

  1. 1. Number of Sessions Required: Most individuals require four to six laser treatments spaced four to six weeks apart to achieve the desired reduction in hair growth. However, this number can vary depending on individual factors such as hair type, skin tone, and hormonal balance.
  2. 2. Duration of Hair-Free Periods: While laser hair removal can significantly minimise and slow down hair growth, it is not a guarantee of permanent hair removal. Most people experience an 80-90% reduction in hair growth, and the remaining hair is usually finer and lighter. Maintenance treatments may be necessary to prolong hair-free periods, usually once or twice a year.


Comparison With Other Hair Removal Methods

Laser treatment isn’t the only option when it comes to hair removal. Other treatments include shaving, waxing, electrolysis, and epilation.


LED Hair Removal Treatment

Unlike traditional laser hair removal methods that utilise single-wavelength laser technology, LED Hair Removal Treatment uses a range of wavelengths. It employs multiple light frequencies to target and destroy hair follicles, reducing the number of unwanted hairs in a given area.

The procedure begins by applying a cooling gel to the area undergoing treatment. Then, the practitioner guides the LED device across the skin, emitting pulses of light that penetrate the skin to reach hair follicles. These follicles absorb the light, and the heat generated destroys them, inhibiting future hair growth.


Shaving is a quick and inexpensive method to remove unwanted hair. However, it only cuts the hair at the skin’s surface, which can lead to rapid regrowth and the appearance of “stubble.” Additionally, shaving can cause skin irritation and may contribute to ingrown hairs.



Epilation involves using a device that mechanically grasps and removes multiple hairs simultaneously from the root. While it offers longer-lasting results than shaving, it can be painful and cause skin irritation or ingrown hair.



Electrolysis is a more time-consuming and costly medical procedure wherein fine needles are inserted into hair follicles, and administer electric current to destroy the follicles. Although it can offer permanent hair removal, the process can be tedious and may require many treatments to cover the affected area.

Having explored the various hair removal methods, it is clear that laser hair removal presents a more long-lasting and effective solution for many individuals.


Tips For Maximising Laser Hair Removal Results

Here are some tips to maximise your laser hair removal treatment and prolong its effects.


Choose The Right Aesthetics Clinic And Practitioner

Select a reputable clinic with experienced practitioners who are knowledgeable about different laser technologies and can tailor the treatment to your specific skin tone, hair colour, and treatment area.


Prepare For Laser Hair Removal

Properly prepare for laser hair removal by avoiding sun exposure, tanning beds, and skin-lightening treatments before your sessions. Additionally, avoid waxing, plucking, or epilating the hair in the affected area for several weeks before treatment, as the laser targets the hair within the hair follicle.


Post-Treatment Care And Maintenance

Follow your practitioner’s recommendations for post-treatment care, such as avoiding sun exposure and using a gentle, fragrance-free moisturiser to soothe the treated area. You may also need maintenance laser treatments to manage any future hair growth.


Adjusting Expectations And Embracing Touch-Ups

Understand that laser hair removal is not a guarantee of permanent hair removal, and hair may regrow in the future. Be prepared for the possibility of touch-up treatments to maintain your desired results.


Possible Risks And Side Effects Of Laser Hair Removal


Common Side Effects

Mild redness, swelling, or irritation may occur after the treatment, but these are minimal and will usually subside within a few hours to a few days.


Rare Complications

In rare cases, individuals may experience burns, blisters, or changes in skin pigmentation. To minimise these risks, choosing a qualified practitioner and following their pre- and post-treatment instructions is essential.


How to Minimise Risks

Choose a reputable clinic, follow your practitioner’s guidelines, and communicate any concerns or issues you may have during the hair growth cycle. Additionally, be honest about your medical history, as certain medications or conditions can affect the treatment’s safety and efficacy.
