How Does Laser Hair Removal Work

When you’re looking for a permanent answer to unwanted hair or someone to help you with it, the futuristic service of laser hair removal may help you. This popular operation can attack the hair follicles through concentrated light, meaning hair growth will be minimized but not the skin around them. It was the shins, thighs, and forearms – lasers even hit the armpits too!

By the time it shaved, people only had to let their hair grow back shortly afterwards because everyone was waxing. You’ll also learn how to remove laser hair from the technology behind this procedure and the procedures performed. With this understanding, a person can better learn it for laser hair removal and aim to have smoother, hairless skin.

The Science Behind Laser Hair Removal

Beyond hair removal, laser is a cosmetic procedure and a technology-driven solution based on light and biology. What is known as the process is to focus with the use of certain lasers on disrupting the growth cycle of hair follicles, thereby reducing overall hair growth.

Understanding the scientific foundation of this method can hint at how effective it is likely to be and for which types of hair and skin it works best.

Selective Photothermolysis

The basic principle of laser hair removal is called selective photothermolysis. The idea is to use within a narrow margin of error a certain wavelength of light with pulse duration and whatnot to specifically target a chromophore (melanin, in this case, to hair) without harming the surrounding tissue.

When the melanin in the hair follicle absorbs the laser light, it transmutes into heat and damages the follicle so that no more hair will ever grow in the future.

Melanin Absorption

Melanin, responsible for hair and skin colour, is crucial in removing body hair. A laser has to be relied on for removing body hair; the laser depends upon melanin in the hair to take the light. This is why the procedure is most effective on people with a high contrast between hair and skin colour.

However, technological improvements in lasers have made it increasingly possible to treat a wider range of skin and types of hair.

Hair Growth Cycle

Hair grows in cycles; we can identify the anagen (growth), catagen (transitional), and telogen (resting) phases. Laser hair removal is most effective during the “anagen” phase when hair is actively growing and melanin concentration is highest.

It is why multiple treatment sessions are needed, spaced out over several weeks, to zap all the hairs in their growth phase at the time of treatment.

Types of Lasers

Different types of lasers are being used to rinse flesh of unwanted or unsightly hairs, each well aligned at a specific wavelength to best target melanin in different skin and hair types. Some common ones are:

  • Alexandrite
  • Diode
  • Nd:YAG
  • Ruby

What makes laser hair removal work? It is a combination of physics and biology, ensuring that the treatment is effective and safe for all kinds of skin and hair. Using the body’s natural responses to light and heat, laser hair removal is a scientifically proven hair reduction method.

The Procedure of Laser Hair Removal

The Procedure of Laser Hair Removal

A journey into the world of light-form hair removal can be exciting. The laser hair removal process is all-encompassing and consists of several key stages, from the initial consultation to the final treatment. If you understand each step, you won’t be startled by what happens in the future.

Initial Consultation

To get started, schedule a meeting with an approved professional for the first laser hair removal. At this initial meeting, the practitioner will determine your skin type, hair colour, and body part of focus. It is a critical time for clarifying goals and expectations.

It’s also prudent to share any past treatments with your doctor. The specialist will also detail the procedure, such as how many sessions are usually needed and what patients should do, if anything, before treatment.


Preparation is an essential part of laser hair removal. It is often recommended that candidates avoid sun exposure, waxing, and plucking in the weeks leading up to treatment.

These things can make the process ineffective. To ensure the laser hits the hair follicles directly, shaving the area a day or two before treatment is generally recommended.

The Treatment Sessions

During the process of laser hair removal, the handheld device emits light. The hair pigment absorbs this light. The light energy is converted into heat, damaging the hair follicle and inhibiting growth. People often claim the feeling resembles having a rubber band snap against the skin.

Cooling mechanisms or the application of gels are used to minimize discomfort. Each session’s length changes depending on the treatment area. A few minutes for small places like the upper lip, or an hour for lots such as backs or legs.

Post-Treatment Care

Each session may cause some redness and swelling, comparable to a mild sunburn. Use cooling gels or ice packs to relieve this discomfort. It is important to follow your practitioner’s post-treatment care advice, often including avoiding sunlight and sunscreens for the treated area.

Follow-up Sessions

Getting rid of hair by laser is a process that usually results in several sessions. Several weeks are likely to pass between these sessions because hair grows naturally. The number of treatments depends on the individual. Most people see at least 3-7 treatment sessions, although there are those whose hair is essentially gone after the third session.

Long Term Effect

Although laser hair removal can reduce hair growth significantly, it’s important to remember that results can differ. Some require periodic touch-up sessions to maintain results, particularly in regions influenced by hormonal influences.

Comparing Laser Hair Removal with IPL Products

Comparing Laser Hair Removal with IPL Products

Regarding effective methods for removing unwanted hair, laser hair removal and Intense Pulsed Light (IPL) stand out as two of the most popular choices.

While they might seem similar at first glance, delving into their differences reveals distinct advantages and considerations for each. Understanding these distinctions can help them make informed decisions about which method might be best suited to their needs.

Technology and Precision

Laser hair removal employs a single, concentrated wavelength of light to target hair follicles, offering high precision. This focused approach allows for the energy to be absorbed specifically by the melanin in the hair, minimizing the risk to the surrounding skin.

The broad-spectrum light with multiple wavelengths in IPL, on the other hand, makes it less targeted. This can affect the treatment’s efficiency or effectiveness for various hair and skin colours.

Effectiveness on Different Skin Tones

Laser hair removal technology has the significant advantage of being adaptable to various skin tones and with the appearance of newer lasers like the Nd:YAG, which is safe for darker skin.

Its wider spectrum makes it less suitable for people with darker skin tones or lighter hair shades-the light may not be absorbed by the hair follicle fast enough to be fully effective.

Treatment Sessions and Duration

Laser hair removal generally needs fewer sessions than IPL to yield similar results. The laser can pinpoint with far greater precision because it can damage the hair’s root more effectively, thus inhibiting regrowth.

Although they will gradually have an effect, IPL treatments often require more sessions, especially with less ideal hair or skin colour combinations.

Cost Considerations

The cost of laser hair removal is more expensive than with IPL-first and if it is done in a professional establishment. However, if there may be fewer sessions and the effects last longer, it is better value in the long run.

IPL devices, particularly at-home ones, are a cheaper way into the market but may cost you more in the long run when you have to have them daily.

Convenience and Accessibility

For convenience, IPL is available in at-home devices such as Braun hair removal, allowing for treatment when you want. Laser hair removal is carried out in a professional setting and requires appointments and travel, but it also has the advantage of being overseen by competent staff.


The laser hair removal technology embodies a modern method for removing unwanted hair that wisely combines precision targeting hair follicles and needing no line lines leading into the skin. This process provides a more permanent option for removing hair than traditional methods with several body parts that can last.

This kind of knowledge, which causes an absence of scars or pain to be felt during the procedure – is not only now coveted, sensationalist, but scary! When people comprehend how this thing operates, there is no way they will come off as total babies about it. The sun is outrageous, but laser hair removal doesn’t hurt you.
