How do Lasers Remove Unwanted Hair?

Around the world, laser hair removal has emerged as one of the most well-liked and highly sought-after cosmetic procedures. Thanks to advanced technology, individuals no longer have to deal with tedious and troublesome hair removal methods such as waxing, tweezing, and shaving that require constant maintenance.

In this blog, Dr. Rajdeep Mysore, a renowned skin specialist, has shed some light on laser hair removal, its mechanisms, and how it works. The leading doctor practises at Charma Clinic, which is widely known for offering the best Laser Hair Removal in Bangalore. Keep reading for more insights.

How Does Laser Hair Removal Work?

During a laser hair removal procedure, an intense beam of light is targeted. This light goes down to the hair follicles and gets absorbed by the melanin in the hair. This results in eliminating hair roots and allowing blood flow to the base of the hair to grow actively. Laser hair removal only works for hair in the anagen phase. After the first session, the targeted hair falls on its own. Most individuals are satisfied with 6–8 laser sessions that are spaced over a period of 4-6 weeks.

Laser hair removal is done for both men and women and works best for all skin types. The laser light gets absorbed by dark hair more effectively than lighter skin.  This happens because of the requirement for hair and skin color. Thus, it is vital to have hair with a significant amount of melanin. The ones with blonde or gray hair will not get effective results.

How Laser Heat Targets Hair Follicle?

Ever noticed how dark clothes absorb sunlight and feel warm when touched? If yes, then one will better understand how the melanin (pigment) beneath the hair follicles absorbs the heat from the lasers. Laser hair removal works through a process called selective photothermolysis. This is when the laser beam is set at a desired wavelength. The melanin found in the hair attracts the laser beam, leaving the surrounding tissue unaffected. The laser beam's energy is converted into heat when it passes through the hair shaft and into the actual hair bulb. The dermal papilla, which feeds the hair bulb and regenerates the hair, is killed and destroyed by the heat in this area. After just two sessions, the hair will grow back slowly and be finer. 

Below are the three phases of hair growth:

  1. Anagen

Anagen is called the growing stage. This is the phase when the roots of the hair have the largest and excess of melanin and are attached to the roots. During this phase, the hair keeps growing and becomes apparent above the skin. The length of this phase will depend on how long the hair grows. This is also the phase where the hair is at its darkest pigment, and this allows for the best transfer of heat energy from the lasers to the hair follicles.

  1. Catagen

The catagen phase is also called the transition stage. During this time of transition, the hair follicles get smaller and stop developing. The hair follicles break away from the dermal papilla that provides them with nutrients. This stage lasts for a few days.

  1. Telogen

The telogen phase is also called the resting stage. Laser hair removal is absolutely ineffective at this stage since the hair is fully detached from the root and cannot be noticed. This stage might last for as little as a week or as long as a year before returning to the anagen phase, therefore, there is no set time for it to last.

The Different Technologies Used at Charma Clinic to Deliver the Best Outcomes

  1. Intense Pulsed Light technology (IPL)

 This is the most effective technology that makes use of pulses of light that are targeted at the hair roots. This makes the hair switch to its resting phase. And, when they fall out, the body grows less hair in that area.

  1. Diode Laser

Diode lasers are known for offering effective results in less time, and this technology is safe for individuals with darker skin tones. The lasers use an 810 nm wavelength (longer wavelength if compared to alexandrite lasers), which is very effective in treating thicker hair.

  1. Alexandrite Laser

Alexandrite lasers use alexandrite crystals as the laser medium. The lasers produce a specific wavelength of light (755 nm) and are effective for individuals with light skin and darker hair.
