How many times should I do laser until all the hair is gone?

How many times should I do laser until all the hair is gone?

Short answer – nobody knows, and nobody can give you a definite answer. Should anyone tell you 6, 8, 20, or any actual number, it would be misleading you. 


1. We know that for most customers, every single laser hair removal treatment reduces hair coverage by 15% on average from what is left. 

2. To get rid of the majority of the hair, you need to do 5-8 treatments on some parts of your body and 8-10 times on other parts.

Below, you can find actual data for customers who came to us for laser hair removal and stopped scheduling new appointments. We did not count those customers who are still doing laser hair removal as their process still needs to be finished. 

The following are remarks about laser hair removal treatments, the number of sessions, and why you can see such a significant deviation in the number of treatments.

  1. Customers who did 1-3 laser hair removal treatments either needed to do touchups, were temporary in this area, or were, for whatever reasons, decided not to do laser hair removals anymore. You can disregard those who did 1-3 treatments only, as more than three treatments are needed to get rid of the majority of your hair. # Treatments can reduce your hair coverage but will not eliminate hair. 
  2. Customers who did 12-20+ laser hair removal treatments. There is a large group of the population that has PCOS or similar conditions. According to CDC  PCOS is one of the most common causes of female infertility, affecting 6% to 12% (as many as 5 million) of US women of reproductive age. However, it is a lot more than that. This lifelong health condition continues far beyond the child-bearing years. Women with PCOS are often insulin resistant; their bodies can make insulin but cannot use it effectively, increasing their risk for type 2 diabetes. They also have higher levels of androgens (male hormones that females also have), which can stop eggs from being released (ovulation) and cause irregular periods, acne, thinning scalp hair, and excess hair growth on the face and body
  3. We removed two extremes from our data, and what is left is the average number of treatments our customer did for their laser hair removal. As we can see, the average numbers are different, from part of the body to different locations (ethnic makeup of customer base). Looking at the average can make some understanding, such as how many times someone did laser hair removal for a given body part. 
  4. Also, please pay attention to the following conditions affecting the number of laser hair removal treatments one might require.
    1. Age. Generally, the younger one is, the more treatments one would need. During laser hair removal sessions, some hair follicles will be permanently destroyed. They will not resurrect, while some follicles will be thermally damaged, and a younger/healthier body will be able to repair more of the damaged follicles compared to older ones.
    2. Ethnicity. Those who have more hair to start with would need more treatments compared to those who started with less hair coverage.
    3. Health conditions. Please see the example with PCOS. Someone with PCOS, instead yes than not, would need more treatments down the road compared to a similar person without the said condition. If, for whatever reason, one has increased hair growth, one would likely need more treatments compared to someone without the said condition. 
    4. Hair color/thickness. There should be enough contrast between skin and hair color. Hair must be darker than the skin! There is no way around it. Once hair becomes gray/white, laser hair removal would do nothing to help.
    5. Not everyone wants to get rid of every last hair. For the majority of customers, shaving once a month instead of shaving underarms or legs or bikini every day is a significant achievement, and they are acceptable to shave four leftover hair once a month compared to the 100,0000,000 hair they began with (numbers are just examples). However, some do want to get rid of every last piece of hair on their body. Naturally, they would need to have more laser hair removal treatments.

Now, we can examine our charts and approach to interpretation with basic knowledge about “how laser hair removal works.”

What would we suggest, and how can you save big now when you know how does it works? As you can see, average clients had at least 5-6 laser hair removal sessions. You can purchase a gift card for five times your laser hair removal session price and save 10-20%, as you know you would need to do at least five sessions of laser hair removal. Link for the gift cards is here:
