What Is Paradoxical Hypertrichosis?
Paradoxical hypertrichosis refers to the unexpected stimulation of hair growth in or around the area treated with light-based hair removal systems like laser or IPL. Instead of reducing the hair, these treatments sometimes cause fine, vellus hairs to become thicker, longer, and darker — a completely unintended and frustrating side effect.
Why Does It Happen?
The exact cause is still being researched, but several contributing factors have been identified:
- Subtherapeutic energy levels – If the energy used is too low, it can warm the hair follicle just enough to stimulate rather than destroy it.
- Hormonal conditions – Clients with hormonal imbalances (such as PCOS) are more prone to reactive hair growth.
- Genetics and ethnicity – Individuals with Mediterranean, Middle Eastern, South Asian or Latin heritage (often Fitzpatrick Skin Types III to V) tend to be more predisposed to paradoxical hair growth.
This issue is particularly common in areas of the body where hair is already fine and light—like the face, neck, or upper arms—and it can be especially distressing when these areas begin to grow more coarse and visible hairs after treatment.
Why Electrolysis Is the Best Solution
Once paradoxical hypertrichosis occurs, continuing with laser or IPL may only worsen the condition. This is where electrolysis becomes a game-changer.
Electrolysis is the only TGA and FDA-recognised permanent hair removal method, and unlike laser or IPL, it treats each individual follicle with precision. It doesn’t rely on pigment, making it ideal for treating fine, light, or hormonally stimulated hair—including regrowth caused by paradoxical hypertrichosis.
At Skin Correctives, we use the Apilus xCell Pro, one of the most advanced electrolysis systems available. What makes it different?
The Power of 27.12 MHz High Frequency
The Apilus xCell Pro operates at a unique 27.12 megahertz frequency, which allows for faster, more precise, and more comfortable treatments. This higher frequency targets the hair follicle with exceptional accuracy while minimising the spread of heat to surrounding tissue. That means:
- Less discomfort during treatment
- Lower risk of skin trauma or pigmentation changes
- Faster healing and minimal inflammation
This is especially important when working on skin that is already prone to irritation, inflammation, or post-inflammatory pigmentation—such as Fitzpatrick Types III–VI.
Why Gentler Electrolysis Matters
Skin types affected by paradoxical hypertrichosis often have melanin-rich skin, which requires a more delicate approach to avoid triggering hyperpigmentation or scarring. Using older electrolysis technology or overly aggressive settings can create unnecessary trauma.
With the Apilus xCell Pro, we can choose more refined, tailored programs that allow us to treat these areas safely and effectively. It also enables the use of pulsed current and special modalities such as Synchro or PicoFlash, which deliver energy in ultrafast bursts to destroy the follicle while protecting the surrounding skin.
In Summary
Paradoxical hypertrichosis can be emotionally challenging and physically persistent, but it is treatable. The key is switching to the right method—a permanent one—and choosing a skilled electrologist who understands the unique needs of your skin and hair type.
At Skin Correctives, we bring over three decades of experience and internationally recognised qualifications in electrolysis. Our advanced Apilus xCell Pro technology allows us to treat even the most complex cases safely, comfortably, and effectively.
If you’re concerned about increased hair growth after laser, or if you’ve been told there’s nothing more that can be done—please know there is a solution. We’re here to help you feel confident in your skin again.
