For many people, unwanted body hair can be a source of frustration. Shaving, waxing, and other hair removal methods can be time-consuming, inconvenient, and sometimes even painful.
Laser hair removal offers a more permanent solution, but one common question many people have is: how long does it take for hair to grow back after treatment?
Keep reading to learn more about laser hair removal, including when you can expect to see hair reappear after treatment!
What Is Laser Hair Removal?
Laser hair removal uses concentrated light energy to target and damage the pigment (melanin) in hair follicles. This damage disrupts the follicle’s ability to produce new hair growth.
While laser hair removal can significantly reduce unwanted hair growth, it’s important to understand that it’s not a one-time fix. Your doctor at Center for Dermatology and Laser Surgery can help you achieve long-lasting results, but multiple sessions are typically required.
Shelby Saltsman, PA-C at Moy-Fincher-Chipps, a Golden State Dermatology Affiliate, says: “Laser hair removal offers a long-term solution for unwanted hair, but understanding the regrowth process is key to managing expectations. While patients may see a significant reduction in hair growth after their initial treatments, some maintenance sessions might be needed over time to maintain optimal results.”
The laser specifically targets hair in its active growth phase (anagen phase), which is why multiple sessions are necessary. Hair follicles cycle through different phases, and only those in the anagen phase are susceptible to laser treatment.
Subsequent sessions target hairs entering the anagen phase after previous treatments.
Who Is a Candidate for Laser Hair Removal?
Laser hair removal is most effective on individuals with dark, coarse hair and lighter skin tones. The laser targets melanin, so a higher contrast between hair and skin allows for better absorption of the laser energy.
However, advancements in laser technology have improved effectiveness for individuals with lighter hair and darker skin tones.
Your doctor at Center for Dermatology and Laser Surgery can assess your skin and hair type to determine if laser hair removal is the right option for you.
Kaitie McKeever, registered nurse at Moy-Fincher Chipps, a Golden State Dermatology Affiliate, explains, “We provide patients with an in-depth skin and hair assessment to determine if they are a candidate. If they are not, we use the findings from these assessments to decide on other solutions. This personalized approach helps ensure that each patient receives the most effective treatment for their specific skin and hair type.”
Factors Affecting Hair Regrowth After Laser Hair Removal
Several factors influence how long it takes for hair to grow back after laser hair removal:
Area Treated: Hair growth rates vary across different body areas. Areas with faster hair growth, like the face and underarms, may see regrowth sooner (weeks) compared to areas with slower growth, like legs and back (months).
Skin Tone and Hair Color: As mentioned earlier, higher contrast between hair and skin allows for better laser absorption and results. Individuals with darker hair and lighter skin tones typically experience longer-lasting hair reduction.
Hormonal Fluctuations: Hormones play a significant role in hair growth. Hormonal changes due to puberty, pregnancy, menopause, or certain medications can influence hair regrowth patterns and may lead to some hair returning after laser treatment.
Number of Treatment Sessions: Completing the recommended number of laser hair removal sessions is crucial for achieving optimal results. Each session targets hair in the anagen phase, and multiple sessions are needed to address follicles throughout their growth cycle.
Individual Variations: Everyone’s body is unique, and hair growth patterns can vary significantly. Some people may experience permanent hair reduction after a series of treatments, while others may require maintenance sessions periodically.
What to Expect After Laser Hair Removal
Following laser hair removal treatment, you may experience some redness, swelling, or mild discomfort in the treated area. These side effects are usually temporary and resolve within a few days.
It’s important to follow post-treatment instructions provided by your doctor, which may include avoiding sun exposure, applying sunscreen, and using gentle skincare products.
In the weeks following treatment, you may notice treated hairs shedding. This is a positive sign that the laser treatment has been effective.
However, it’s important to avoid plucking or waxing treated hairs, as this can disrupt the hair growth cycle and potentially affect future results.
How Do I Maintain the Results of Laser Hair Removal?
While laser hair removal can significantly reduce unwanted hair growth, some regrowth may occur over time. This is because hair follicles can become dormant but not completely destroyed.
Hormonal fluctuations can also stimulate new hair growth. Touch-up treatments may be recommended every 1-2 years to maintain optimal results, depending on individual factors.
How Many Treatments Are Needed for Laser Hair Removal?
The number of laser hair removal treatments required to achieve optimal results can vary depending on several factors. Typically, a series of 6-8 treatments, spaced 4-6 weeks apart, is recommended for most individuals.
However, some people may require more or fewer sessions to achieve their desired results. It’s important to note that laser hair removal is not a permanent solution.
Some hair follicles may remain dormant and eventually produce new hair. Therefore, maintenance treatments may be needed every few months or years to keep unwanted hair growth at bay.
Your doctor at Center for Dermatology and Laser Surgery can provide a personalized treatment plan based on your specific needs and expectations.
What Are the Common Side Effects of Laser Hair Removal?
While laser hair removal is generally safe and well-tolerated, some common side effects may occur:
Redness: This is a common side effect that typically resolves within a few hours.
Swelling: Mild swelling may occur in the treated area.
Blistering: In rare cases, blistering may develop, especially in individuals with darker skin tones.
Hypopigmentation or Hyperpigmentation: Temporary changes in skin color may occur, but they usually fade over time.
It’s important to choose a qualified and experienced provider like those at Center for Dermatology and Laser Surgery to minimize the risk of side effects and optimize results.
Laser hair removal offers a long-lasting solution for unwanted body hair. While hair may regrow after treatment, the regrowth is typically finer and sparser than before.
The number of sessions needed and the length of time it takes for hair to grow back after treatment vary depending on individual factors. Your doctor at Center for Dermatology and Laser Surgery can create a personalized treatment plan to help you achieve your desired results.
