Why Does Hair Regrow After Laser Hair Removal?
Have you ever completed a laser hair removal session only to notice hair growing back?
It can feel disheartening, but rest assured, you’re not alone and it’s not a sign that your treatment isn’t working.
In this blog, we’ll explore why this happens, explain the process behind laser hair removal, and share tips to help you maximise your results. By the end, you’ll have a clear understanding of why regrowth occurs and what steps you can take to address it.
How Hair Grows – The Three Phases
To understand why some hair grows back after laser hair removal, it’s important to first understand the hair growth cycle.
Every hair on your body undergoes three distinct phases
- Anagen Phase – This is the active growth stage where the hair is fully connected to the follicle.
- Catagen Phase – The transitional phase where the follicle begins to shrink.
- Telogen Phase – The resting stage where the hair eventually sheds.
Here’s the key – laser hair removal is most effective during the anagen phase.
At this stage, the laser’s energy is absorbed by the pigment in the hair, damaging the follicle and preventing future growth. However, not all hairs are in the anagen phase at the same time, which is why multiple sessions are necessary to achieve optimal results.
Why Does Hair Regrowth Happen?
After a treatment, what may look like regrowth is often part of the natural process. Here’s what could be happening
- Hair Shedding – You might notice hairs falling out after a session, which is a good sign that the laser has effectively targeted them.
- Dormant Hairs Activating – Hairs that were in the catagen or telogen phase during your last session may now be entering the anagen phase, making them visible. This isn’t new hair, it’s simply hair that wasn’t ready to be treated before.
- Hormonal Influences – Factors like pregnancy, menopause, or conditions such as PCOS can stimulate new hair growth, even after successful treatments.
- Realistic Expectations – While laser hair removal significantly reduces hair growth, it’s not 100% permanent. Some follicles may survive and produce finer, lighter hair over time.
Achieving the Best Results
Laser hair removal is a process, and consistency is key. Here are some tips to maximise your results
- Stick to Your Treatment Schedule – Regular sessions ensure the laser targets as many hairs in the anagen phase as possible. Missing sessions or spacing them too far apart may allow dormant hairs to grow back.
- Avoid Plucking or Waxing – These methods remove the hair follicle, which is what the laser needs to target. Instead, opt for shaving between sessions if necessary.
- Protect Your Skin – Use sunscreen to prevent sensitivity and pigmentation issues caused by sun exposure.
- Tailored Treatment Plans – Factors like skin tone, hair colour, and hormonal influences can affect results. A personalised consultation with a professional is essential to create a plan suited to your needs.
Regrowth after laser hair removal is normal, but it doesn’t mean the treatment isn’t working. Patience and consistency are crucial. With each session, you’ll see significant progress towards smoother, hair-free skin.
