How does laser hair removal work?

laser hair removal

Individuals having unwanted body hair can be a significant problem and need smooth, clear skin. Laser hair removal become the most preferable choice for the person dealing with unwanted hair problems. The therapy has long-lasting results compared to other hair removal treatments, which are temporary solutions like shaving, waxing, and plucking. The procedure uses a wavelength of energy light and targets the area of hair to remove it, resulting in hair reduction.

Let’s explore the science behind laser hair removal to understand how this transformative process works.

The Basics of Laser Hair Removal

A concentrated beam of light is used to permanently remove unwanted hair by targeting hair follicles with laser technology. The hair pigment absorbs light energy and converts it to heat, damaging the follicle and inhibiting growth. This procedure effectively decreases hair growth in the targeted region through several treatments.

The Science Behind the Process

The usefulness of laser removal is based on particular photothermolysis, where the laser radiates a wavelength absorbed by the hair follicle and undervalues impairment to the surrounding skin. The wavelength used for hair removal relies on skin tone and hair colour.

Melanin, the pigment liable for colouring hair and skin colour, is pivotal in the procedure. More unlit hair holds higher levels of melanin, making it a target for laser energy absorption. 

Conversely, the surrounding skin should ideally have lower melanin levels to avoid unintended damage. This is why individuals with lighter skin and darker hair tend to achieve the best results with laser hair removal.

The Procedure and Treatment Plan

During a typical laser hair removal session, the following steps are usually taken:

1. Preparation: Preparation needs to be done before the treatment starts. The area where treatment is accomplished has to be shaved to provide the laser energy focused on the hair follicles rather than the visible hair above the skin.

2. Application of Gel: The gel is used on the skin area to help protect it from the heat generated by the laser and enhance light penetration.

3. Laser Pulses: The laser is then directed at the treatment area, emitting light pulses. These vibrations are gripped by the melanin in the hair follicles, causing heat and impairing their ability to regrow.

4. Discomfort Management: It is often stated as a crackling whiz of despair, perhaps adept throughout the process. Many modern laser systems include cooling mechanisms to minimise discomfort.

5. Aftercare: After the session, the treated area might appear slightly red or irritated, but this typically subsides within a few hours. Sun protection is crucial in the days following treatment to prevent any potential complications.

6. Achieving Optimal Results: It’s important to note that achieving optimal results with laser hair removal requires multiple sessions. Hair growth occurs in cycles; the laser is most effective during the active growth phase. Consequently, several weeks apart, a series of sessions is recommended to target hairs in various growth stages.

Benefits and Considerations

There are several advantages to opting for hair removal, and if you want to know why use laser hair removal, see the benefits and considerations, including:

1. Precision: The laser targets specific hair follicles while leaving surrounding skin unharmed.

2. Speed: Each laser pulse covers a relatively large area, making the procedure suitable for small and large treatment areas.

3. Long-lasting Results: Many people go through a noticeable decrease in hair growth that can last for months or even years, but it’s not entirely permanent.

Mentioning Some of the Concerns to Keep in Mind

1. Type of Skin and Hair: The success of laser hair removal depends on the contrast between skin colour and hair. Individuals with lighter skin and darker hair often exhibit specific characteristics that respond best.

2. Multiple Sessions: Multiple sessions are necessary for the best results, which may require time and financial commitment.

3. Potential Risks: While rare, risks include skin irritation, changes in skin pigmentation, and blistering. Choosing an experienced practitioner and following proper aftercare instructions can minimise these risks.


Laser hair removal has revolutionised the way individuals approach unwanted hair. By harnessing the power of light and leveraging the science of selective photothermolysis, this procedure offers a semi-permanent solution for those seeking smooth, hair-free skin. While considerations exist, technological advancements and expert guidance have made laser hair removal increasingly popular and practical for achieving long-lasting results.
