These days, hair-free doesn’t have to mean painful waxes or time-consuming shaving rituals. Laser hair removal is the modern-day gold standard for smooth skin and reduced hair growth, thanks to its ability to target hair follicles. 


Our treatment uses concentrated light to deactivate hair follicles and prevent regrowth. The process is non-invasive, safe, and ideal for individuals seeking smooth skin without the hassle of outdated hair-removal methods. The results are generally permanent, although some patients may require maintenance sessions. 


Laser hair removal does require commitment. Patients require multiple sessions for it to give the results you want. How many laser hair removal sessions, you ask? Let’s find out below.


What Is the Hair Growth Cycle?


To understand why you need more than one session, it’s important to know the fundamentals of the hair growth cycle. Hair grows in three phases:

  • The anagen, or growth phase, is when hair actively grows and is the most responsive to laser treatment.
  • There’s a short period when the hair stops growing and detaches from the blood supply, known as the catagen, or transitional, phase.
  • Eventually, the hair falls out. This stage, called the telogen or resting phase, is when hair does not respond to lasers. 


Laser hair removal can only treat hair in the anagen phase. The average number of laser hair removal treatments patients require ranges from 6 to 8, every 4 to 8 weeks, to align with the follicles in various phases. 


How Many Laser Sessions Should I Get?


A common misconception is that you only need one laser hair removal session to be hair-free. Unfortunately, that is not the case. Only a portion of your hair is in its growth phase at any given time; the rest is either undeveloped or preparing to fall out, making it unattainable by lasers. 


On average, around 20% of your hair is in the anagen phase during a hair removal appointment. This means you’d need at least 6 sessions to catch all the hair in its most vulnerable phase. Some areas may require additional sessions, depending on hair coarseness and the area to treat.


Number of Sessions According to Body Area 

While some areas respond relatively quickly to laser hair removal, others may require a few more sessions to achieve your desired results. 

  • Facial hair on the lip and chin is relatively fine compared to other body areas, and can be influenced by hormones. This area usually requires 6 to 12 sessions for effective results.
  • Thick underarm hair responds well to laser treatment, needing 6 to 8 sessions for ideal results.
  • The bikini line is also quick to treat, but could still require 6 to 10 appointments. 
  • Arms and legs cover a considerable amount of space, needing 6 to 10 sessions.
  • In men, the back and chest have dense hair growth and require around 8 to 12 sessions.


What Factors Influence Laser Hair Removal?


Your hair color and skin tone play major roles in the number of sessions you require and the overall effectiveness of your treatment. 


Dark hair and light skin are the perfect combination. The laser targets the hair pigment, so this contrast helps the device easily identify and break down the follicle without damaging the surrounding tissue.


Light-colored hair contains less melanin, making it difficult for the device to detect. This could mean more sessions to realize your goals.


Because dark-toned skin has a high melanin content, it can absorb the laser’s heat, leading to irritation in the area. Darker-skinned individuals may require more sessions or special laser devices to ensure safe and effective treatment. 


How Much Does Laser Hair Removal Cost?


Laser hair removal cost per session can vary depending on several factors, including the size of the treatment area, the number of sittings needed, and your individual hair type and density. Laser hair removal prices by area mean that smaller areas generally cost less than larger treatment areas. Many clients choose package options because they are more cost-effective than booking individual sessions. 


At The Studio Med Spa, we discuss pricing during your consultation so we can recommend a treatment plan tailored to your goals and hair growth patterns. Our laser hair removal packages of three sessions currently start at $149 for small areas, $279 for medium areas, and $419 for large areas. Members may also qualify for additional savings on treatments and packages.
