How Effective Are the Laser Hair Removal Treatment

How Effective Are the Laser Hair Removal Treatment

If you have got fed up of those hair removal methods which is time-taking and painful, then laser hair removal may be the best solution for you.

However, many who haven’t given this method a shot so far may wonder if the treatment is going to last forever or if it is less painful than other procedures.

This article will solve all of your quarries related to laser hair removal while developing a comprehensive understanding of the science behind the procedure.

Before moving on, it is necessary to understand why permanence of the treatment varies from person to person. The success of a laser treatment depends on various factors.

  • Skin color
  • Hair color
  • Type of hair
  • Hair growth cycle

The body part which is to be treated is amongst prominent aspects which determine the permanence of the process.
All these factors vary person to person. Hence each individual needs a different therapeutic approach for complete hair elimination.

Besides, hair growth cycle gets affected by various factors, which again influences the result of the laser hair treatment. Let’s see how these factors influence the end result.

Hair Growth Cycle

It varies person to person. Also, it completes in three stages and each individual hair is at a different phase of the cycle.

This is why you need multiple laser hair removal treatments to completely become hairless.

The very first stage of this growth cycle is called Anagen.

In this phase, hair is growing and is visible to us. This is the only time when laser works its magic via destroying the hair and its follicle so that it never grows back.

The second stage is known as Catagen where hair growth slows down and its follicle starts to get detached from the papilla.

Hair follicle too, starts shrinking at this phase.

In the Telogen or resting phase, the older follicle dies, hair shades down and new hair enters into the growth phase in the papilla.

In a human body, hairs could be at various stages of the growth cycles at a given time.

The time interval between laser sessions is needed to allow more hairs to reach the Anagen phase so that laser can target them the next time.

It is interesting to note that hair growth cycle differs from follicle to follicle. Also, on different body parts, a different pattern of the growth cycle is observed.

This is why a course of three to six sessions is required to remove hairs from a targeted area. What else can new follicles form in the treated area in the long run? Though, these are very sparse and light in color hence, you won’t require another treatment for erasing them.

Targeted Body Part & Type of the Hair

In a human body, there are two types of hair that are observed. Terminal hairs are thick and densely populated in areas like,

  • Head,
  • Underarms,
  • Pubic areas, and

Lower legs show faster growth compared to those tiny Vellus hairs generally found on various body parts in women.

Vellus hair holds less melanin – a pigment that is responsible for hair color. In contrast, terminal hairs which are coarse and tough contain greater amount of this pigment.

Now, the laser targets this melanin to destroy the hair and its follicle.

Clearly, Vellus hairs are hard to destroy via using laser as they have lesser pigment for laser to work upon.

This is the basic reason why sometimes laser doesn’t work effectively and you need another course of treatment to lessen the hair growth or completely remove them.

The above discussion also clears why a different treatment approach is needed for each of your body part.
In other words, laser is more effective in areas having Terminal hairs compared to those with Vellus hairs.

Skin & Hair Color

So far, you have understood that dark colored hairs (which hold larger amount of melanin) can easily be targeted by laser and thus destroyed fully.

But this is never a guarantee that you will get most out of your laser treatment. The reason is if there is less contrast between your hair and body color, the results may not be what is expected from the laser treatment. That said the melanin is also present in the skin to give it its color. The darker the skin is, the more will be the melanin.

Now, if you are a person who has darker complexion, no matter how dark and thick your hair is complete hair removal through laser is hard to achieve. This is because; laser cannot differentiate between melanin present in skin and hair.

Hence, it burns the upper layer of skin rather than completely eliminating the hair from that area.

How Long Does Laser Take To See the Results?

If you are thinking of immediate results from your laser hair removal treatment, it won’t be possible. This is because, after few initial sessions, all the hairs on a targeted area cannot be eliminated.

Most of them are actually in different growth phase; hence, they keep growing until the next session. Once you have done with another sitting at doctor’s clinic, rest of the hairs on treated skin area enter the Anagen phase and become visible.

Though, after a recurring course, almost all the hairs from the area under treatment are eliminated. This means that to see the treatment result you will have to wait for the entire course to complete.

Also, here is an important piece of information for those having darker skin tone; laser can be effective for them too.

Actually, specially designed laser treatments are effective on darker skin type and almost satisfactory results can be achieved through the treatment in lesser amount of time.

If you are still having some doubts, it’s high time that you consult your dermatologist in this regard.
