Some individuals experience an unusual side effect known as paradoxical hypertrichosis, where there is increased unwanted hair growth instead of reduction. While rare, this phenomenon raises concerns among patients who undergo laser treatments expecting a permanent reduction.
This condition involves the unexpected increase of hair growth in or around treated areas – the exact opposite of what the treatment aims to achieve. At Isya Aesthetics, we believe in preventing these possible problems while providing complete education about all aspects of treatments, including expectation management and what one can expect. That is why our satisfaction rate is over 99%!
What is Paradoxical Hypertrichosis?
Paradoxical hypertrichosis refers to the increased growth of hair in areas treated with laser hair reduction or similar light-based hair reduction methods. This happens when the laser treatment, instead of destroying hair follicles, actually stimulates them to produce more hair. The new hair growth is often coarser and darker than before treatment.
How Common is This Condition?
According to research published in medical literature, paradoxical hypertrichosis occurs in approximately 0.6% to 10% of patients undergoing laser hair reduction treatments. The wide range reflects differences in:
- Treatment settings
- Types of lasers used
- Patient skin and hair types
- Body areas being treated
- Any underlying hormonal conditions such as PCOS
- Any supplements or medicines that increase male hormones or its action in the body
- Excessive stress
- And more
Causes of Paradoxical Hypertrichosis
Although the exact cause of hair growth after laser hair reduction is not fully understood, research suggests several possible explanations:
1. Gentle Laser Settings or Not Delivering Enough Energy
Different lasers work at different wavelengths to target hair follicles effectively. If different laser settings are used, particularly lower energy levels, the laser may not fully destroy the hair follicle. Instead, it may rarely stimulate new unwanted hair growth. This can happen especially when someone has a hormonal imbalance, on androgenic medications or supplements or has high stress and they require higher energies than otherwise hormonally balanced patients. However, to balance higher energies with the risk of pain or side effects is a tough rope to walk, and only experts know how to balance it well.
2. Hormonal Imbalances
Individuals with hormonal disorders such as Polycystic Ovarian Syndrome (PCOS) or thyroid imbalances may be more prone to unwanted body hair growth post-laser treatment. These conditions can cause excess androgen (male hormone) production or other hormone production, which leads to increased hair growth.
3. Genetic Predisposition
Some people have a natural tendency toward excessive unwanted hair growth due to genetics. If family members have a history of dense body hair, laser hair removal may trigger more growth instead of reducing it.
4. Underlying Medical Conditions
Certain medical conditions, such as insulin resistance or adrenal gland disorders, may contribute to paradoxical hypertrichosis. The body’s response to laser treatment may vary based on existing health conditions.
Who is at Risk for Paradoxical Hypertrichosis?
Certain factors increase the likelihood of experiencing hair growth after laser hair reduction:
- Women with PCOS or hormonal disorders
- Individuals with Mediterranean, Middle Eastern, or South Asian heritage (genetic predisposition)
- Those with light or fine hair.
- Patients receiving treatment on the face, neck, or rarely upper body
- People using medications that cause hair growth or make hair difficult to treat, such as minoxidil, or anabolic steroids and more.
Paradoxical Hypertrichosis Treatment at Isya Aesthetics
At Isya Aesthetics, our approach to laser hair reduction is designed to give you the fastest and most effective laser hair removal, while minimizing the risk of paradoxical hypertrichosis . We are also specialized in darker skin tones and know how to use all the lasers correctly in all the skin types and can get results on the most difficult to treat cases.
PREVENTION:
1. Expert Assessment
Before beginning any laser hair reduction treatment, our specialists conduct a thorough assessment of your:
- Skin type
- Hair texture and color
- Medical history
- Previous hair removal experiences
- Hormonal history
This helps us create a personalized treatment plan with the right laser type and settings for your unique needs.
Then we track the results of each session, and our doctors increase energies customized to your response to the lasers. If we want more results, we assess if there are any changes or any changes planned in your medications or lifestyle as well, and do blood tests to make sure no hormonal issues have occurred. Then we titrate the lasers accordingly, and deliver!
2. Using the Right Laser for Your Skin Type
Not all lasers are suitable for all skin and hair types. The most effective lasers for permanent unwanted body hair growth reduction include:
- Diode Laser
- Nd:YAG Laser
- Alexandrite Laser
- Combination Diode, Nd:Yag and Alexandrite
Using the right technology significantly reduces the risk of unwanted body hair growth after treatments. At Isya we have Nd:Yag with LightPod NEO, Alexandrite with SoftTouch LHR and the combination of three wavelengths with Soprano Titanium. We continually invest in the latest technology for laser hair removal and are the Key Opinion Leaders and guides on the latest techniques of using these devices. We know how to get results on all skin tones and in all concerns.
3. Ensure Correct Energy Settings
Lower energy levels may trigger hair growth after laser hair reduction instead of eliminating it. An expert must assess the required energy levels for optimal results.
Isya carefully adjusts:
- Energy levels appropriate for each area and skin type and hormonal condition
- Pulse duration based on hair follicle size
- Amount of fluence to ensure proper energy delivery, without discomfort
- Treatment intervals timed with hair growth cycles
