Of all the ways people remove unwanted hair from their bodies, laser hair removal is by far the best. This treatment is quick, and extremely effective, contributing to its popularity. But even then, a lot of people are a bit apprehensive about getting laser hair removal done because of a lack of adequate knowledge about what happens after the treatment, especially after the first session.

To reap the full rewards of laser hair treatment, you have to know what to expect after your first laser hair removal treatment. Immediately after the first session, you will experience a bit of sensitivity and irritation on the skin. After that, you will notice hair shedding, as well as a change in skin pigmentation. Finally, you can see small hair growth on the skin. 

Let’s take a detailed look at what you should expect after the first laser hair treatment session. 

What Happens After The First Laser Hair Removal?

Laser hair removal works by targeting a specific pigment on the skin, and then zapping it with a laser of a particular frequency. The laser is absorbed by the pigment of the hair and is transformed into heat.

The heat is then transferred to the hair follicle, which is destroyed by the heat, preventing further hair growth. 

Now, the procedure can be a bit uncomfortable, which sometimes keeps people from getting it. What also prevents them from going through laser hair removal is a lack of knowledge about what happens after the first session.

Once you get to know what to expect after the first laser hair removal, you can prepare both physically and mentally for the procedure.

Now, let’s take a look at what to expect when getting laser hair removal, especially after the first session.  

1. Skin Sensitivity and Irritation

Skin Sensitivity and Irritation

Since the skin absorbs the laser to convert it into heat, the skin of the targeted area can be a bit more sensitive than usual, especially around 24 to 48 hours after the first session.

During this time, you might also feel mild irritation on the skin of the treated area. To make sure things don’t take a turn for the worst, you must avoid working out and wearing sunscreen and deodorant for around 48 hours after the first laser hair removal session.

Also, avoid saunas, and hot showers so that the skin doesn’t get irritated. Aloe vera gel is very useful in this situation, as it soothes the skin. 

2. Change in Skin Pigments

Another thing you can expect after getting laser hair removal after the first session is a change in your skin pigments. You can experience both Hyperpigmentation where the skin darkens, or Hypopigmentation, where the skin color lightens after getting laser hair removal for the first time.

This happens because sometimes a laser can trigger the skin to produce more melanin or stop producing it. 

3. Hair Shedding

 Hair Shedding

A week after attending the first laser hair treatment session, you can see that the hair has started to shed from the treated area. Some people mistake it as a sign of hair growing back, but this isn’t the case.

During this time, you must not go through any other hair removal procedure, such as shaving, waxing, or tweezing, and let the hair shed as it had been. 

4. Hair Growth

Hair Growth

About 4-6 weeks after getting laser hair removal for the first time, you will see little fine hairs growing on the treated area’s skin. Again, most people mistake hair growth as a failure of the laser treatment, but it is a common misconception. This growing hair will be treated again in the next session, which will make them fall away just like the previous ones. 

Also, this is the time when you should book your next session. 

How Long Does Laser Hair Removal Last After One Session?

The reason you need multiple sessions of laser hair removal is that the results after one laser hair removal treatment don’t last forever.

Usually, the results of the first laser hair removal session last around 4-6 weeks, after which you have to book a second session. 

Final Words

The key to ensuring your laser hair removal treatment is fruitful and without any major side effects is to know what to expect after the first laser hair removal treatment. Once you know what will happen after the first session, you can prepare accordingly.

1. Does laser hair removal work after one session?

A lot of people don’t attend any following sessions after getting laser hair removal once, thinking it will be enough. But in truth, you need between 2 to 6 sessions on average for the laser hair removal to work properly. 

2. How long does a laser hair removal session last?

The length of a laser hair removal session depends on how much hair has to be removed, and the area that is being targeted. If the area targeted is small, then the session will last around 10-15 minutes. On the other hand, for a large area, such as the back, the session can last around an hour. 

3. Can I shave 2 days after laser hair removal?

We suggest against shaving soon after getting laser hair treatment. Doing so will irritate your skin even more, and cause infections. It is best to wait for at least 3-4 days before shaving the treated area.
