Laser Hair Removal: Understanding Science Behind the Treatment

By Your Health Magazine

Tired of constant shaving, painful waxing, or messy creams? You’re not alone. Many people are now turning to laser hair removal as a smarter, long-term solution for unwanted hair. But what’s going on beneath the surface of this treatment? How does it work? And more importantly, is it the right choice for you?

In this detailed guide, we’ll explore the science behind laser hair removal, explain how it works, what to expect, and how to get the best results, especially if you’re considering laser hair removal in Cambridge.

What is Laser Hair Removal?

Laser hair removal is a medical and cosmetic procedure in which light energy is applied to destroy hair follicles and thereby avoid or even stop hair growth altogether. It’s an outpatient procedure that can be applied to the body and is, for this reason, much in demand by women and men.

The primary objective is to slow down hair growth in the long run. Even though everybody has varying effects, there is over-shedding of hair for everybody after a cycle of treatment. The hair of some individuals never grows back.

The Science Behind the Treatment

Laser hair removal uses a concept known as selective photo thermolysis. It sounds complicated, but it’s actually quite straightforward: lasers emit a concentrated beam of light that gets soaked up by the melanin (pigment) in your hair. That light gets transformed into heat and zaps the hair follicle, the tiny sac in the skin that grows hair.

By destroying the follicle, the laser prevents hair growth. The surrounding skin is not affected as only the melanin of the hair shaft is broken by the laser.

That is why the treatment works best on people with a colour contrast between the hair and the skin, light skin and dark hair. But because of technological improvements, people with darker skin colour and lighter hair are also assisted.

How Laser Hair Removal Works?

Treatment is easy and requires a couple of simple steps:

First Consultation: Technician will study the skin and hair type, look at the medical history, and suggest the treatment procedure.
Preparing the Skin: The skin area to be treated is cleaned. You might be asked to shave the skin area 24 hours prior to visiting.
Laser Use: The tool is handheld with which to target the laser beam. You will feel some snappiness or stinging, a feeling akin to a rubber band snapping on your skin.
After-Care: A slight redness and swelling of the treated area can be expected afterward and these should dissipate within an hour or so.

Each session would be anywhere from 15 minutes to one hour or more, depending on the location. Two sessions would typically be necessary because the laser would be treating hairs that are actually growing during that moment.

What Kind of Lasers Are Utilized?

Different lasers are used by clinics depending on your skin colour and hair type. Amongst the most common ones are:

Alexandrite Laser: For light olive to skin.
Diode Laser: For most skin types.
Nd: YAG Laser: For dark skin.
Ruby Laser: For very pale skin.

When you are receiving laser hair treatment in Cambridge, make sure that the clinic uses FDA-approved lasers and customizes the treatment according to your individual needs.

How Effective is Laser Hair Removal?

Laser hair removal is very effective for most individuals. Following a complete course of 6 to 8 treatments, expect:

70% to 90% reduction in hair growth
Hair that does grow back is thinner, lighter, and slower
Smoother skin with fewer ingrown hairs

Effectiveness also varies depending on the part of the body that is being treated. For instance, underarms and bikini lines would react faster than arms or backs.

What Can Be Treated?

You can get laser hair removal in virtually any area you find you have excess hair:

Face, cheeks, upper lip, and chin
Underarm and Arms
Legs and Thighs
Back and Chest
Stomach
Brazilian and Bikini Line

All but a few Cambridge laser hair removal clinics offer personalized packages of treatment for individual areas of the body or full-body treatment.

What to Expect During the Treatment?

If you’re new to laser hair removal, it’s no wonder that you would be apprehensive about it. These are what you should expect from them:

You will be required to wear protective eyewear.
Your technician can utilize cooling gel or employ the use of a cooling tip to minimize stinging.
The laser bursts are similar to tiny electrical shocks. Other individuals explain that it is as though a rubber band has been stretched and snapped.
Your skin will be mildly red or irritated following the treatment.

The majority of individuals are able to go back to normal activities immediately after treatment. But one must not get out into the sun, take hot showers, or exercise heavily for a minimum of 24 hours.

How Can I Ensure I Achieve the Best Results?

To achieve the best from your laser hair treatment in Cambridge, do the following:

Adhere to your treatment schedule—do not miss sessions.
Avoid sun exposure before and after treatments.
Do not wax or pluck hair between sessions—shaving is fine.
Apply sunscreen in treated areas if exposed to sunlight.
Adhere to aftercare instructions from your technician.

Selecting a certified and licensed laser technician is important as well. Always look for reviews, credentials, and safety standards prior to beginning your treatments.

Can Hair Be Permanently Removed?

The “permanent hair removal” term is false. Laser hair removal creates a lasting reduction of hair, but not complete permanent hair removal. Still, a majority of people get lasting effects spanning months or years.

Some of the hair may grow back later, but it is lighter and thinner. Periodic maintenance sessions—a single or double session a year—can leave smooth skin.

Safety and Side Effects

Laser hair removal is extremely safe if done by professionals. Nevertheless, as with all beauty treatments, there are side effects that may occur, such as:

Redness or swelling (generally temporary)
Mild inflammation of the skin
Skin colouring (rare and usually temporary)
In a few instances, blisters or burns (primarily when performed by novice technicians)

To minimize the risk, be certain to visit a reputable clinic that is doing laser hair removal in Cambridge using the latest technology and skilled technicians.
