What is paradoxical regrowth? 

The phenomenon of paradoxical regrowth is observed in patients who use hair removal treatments such as waxing, IPL, and laser. Near the treated area, there is an increased growth of fine, long hairs. 

More precisely, instead of reducing or eliminating hair, the treatment causes an increased regrowth of hair in areas close to the one treated. In women, these manifestations occur on the neck and cheeks following hair removal on the upper lip or chin. Bikini treatments can trigger paradoxical regrowth on the thighs or the navel line. 

Men, on the other hand, notice increased hair growth on their neck and nape after hair removal on the cheeks or neck. Light pulses on their back can abnormally stimulate the follicles on their shoulders. Most of the time, these consequences are due to neglecting the recommended safety measures for IPL technology.  

What factors lead to paradoxical regrowth? 

Unanticipated hair growth after a hair removal treatment can be explained by one or more of the following issues: 

  • Hormonal imbalance: makes hair follicles more sensitive to stimulation, leading to paradoxical regrowth.
  • Genetically fine or intermediate hairs: they absorb very little energy, so they are stimulated instead of being destroyed, and regrow thicker and darker.
  • Insufficient energy: Using an IPL or laser at low power can stimulate regrowth instead of eliminating it.
  • Poor cooling system: An ineffective cooling system can heat unevenly, encouraging neighboring hair growth. 
  • Compensation of nearby vellus hair: A compensatory response in which nearby follicles produce more hairs. 

All these factors can create a compensatory effect, where nearby follicles produce more hairs to make up for those removed. This reaction might affect one IPL user and not another. Whatever your situation, certain prudent steps can spare you such a consequence.

What precautions should you take to prevent paradoxical regrowth?

To avoid hair stimulation after a hair removal treatment, follow these guidelines: 

  • Consult a qualified professional: They will assess your skin and determine the most suitable technique.
  • Use high-quality equipment: This will allow you to set the appropriate light intensity to burn the bulbs without stimulating regrowth or burning your skin. 
  • Check the machine’s cooling system: to protect the skin from thermal damage.
  • Closely monitor the skin and hairs after each session to detect any abnormal regrowth early on.
  • Hydrate and soothe the skin after each treatment to aid in recovery.
  • If you suspect a hormonal imbalance, consult a doctor before starting hair removal treatments.
  • Protect your skin from UV rays before and after treatment. 

If you already have paradoxical regrowth, remember that it’s not a permanent situation. You can effectively and permanently eliminate these hairs without any undesirable consequences. 

How can you treat this unusual regrowth? 

To address paradoxical regrowth, start by revisiting the initial treatment with a skincare expert. Depending on the appearance of the new hairs, they will suggest laser hair removal or electrolysis. 

A combined use of both devices can optimize treatment results. 

The pulse duration should be short to quickly deliver enough energy to destroy the hair. It’s advisable to use high energy levels and intense cooling for a complete elimination of hair structures.

Testimonials about paradoxical regrowth

Here are a few accounts from patients and professionals on paradoxical regrowth

  • <<I had paradoxical regrowth on my chin, and I used laser, which effectively removed those thick hairs. However, it was quite tedious because I needed more than eight sessions to get my chin smooth again>>
  • <<I’m currently undergoing laser hair removal sessions and have had no issues. My friend, who has hormonal imbalances, saw several dermatologists who advised against any form of hair removal>>
  • <<With sufficiently high fluences and a good cooling system, you won’t have problems with unexpected regrowth.>>
  • <<Due to a hormonal imbalance, I experienced an abnormal hair surge on my neck. I consulted a specialist who recommended combining laser and electrolysis. I’m on my fourth session, and I think it’s working well for me>>

By following the safety guidelines for laser or IPL, you won’t face unpleasant regrowth. If it occurs despite your precautions, consult an expert for advice tailored to your situation.  

FAQ: 

What other factors can promote paradoxical regrowth?

A very short interval between sessions, tanned skin, or the use of photosensitizing products can increase the risk. Follow the professional’s recommendations to prepare your skin.

Why should you space out your hair removal sessions?

Spacing out sessions targets hairs in the correct phase of their growth cycle. This maximizes effectiveness and reduces the risk of stimulating nearby follicles.

Does paradoxical regrowth affect all users?

No, it’s more common in individuals with hormonal imbalances, dense vellus hair, or genetically fine hairs. Consult an expert to evaluate your risks.
