What to Do if Laser Hair Removal Doesn’t Work

Laser hair removal is often marketed as a long-term solution for unwanted hair, but what happens when the results don’t meet expectations? 

Many Australians invest in multiple laser sessions to find their hair growing back just as before. If you’re wondering Why laser hair removal isn’t effective? What do you do if laser hair removal isn’t working? You’re not alone.

There are many reasons why laser treatments may fail, from hair and skin type mismatches to improper aftercare. The good news is that there are ways to fix bad laser hair removal results and improve your chances of success.

Let’s Get Straight to the Point

If your laser hair removal results aren’t as expected, here’s a quick summary of what you can do:

✔ Assess the root cause: Check if your skin and hair type are suitable for laser treatment.

✔ Review your treatment plan: Ensure you get the correct number of sessions at the correct intervals.

✔ Check laser technology: Not all lasers work for all skin and hair types.

✔ Follow proper aftercare: Sun exposure, shaving, and skincare impact results.

✔ Consider alternative methods: Electrolysis or IPL may work better for stubborn hair.

Now, let’s go deeper into troubleshooting laser hair removal results and how you can improve laser hair removal results for long-lasting, smooth skin.

Reasons Why Laser Hair Removal Fails

1. Your Hair Type Isn’t Suitable

Laser hair removal works best on dark, coarse hair. The laser targets melanin (the pigment in hair), absorbing the light energy and destroying the follicle. If your hair is too light—blonde, red, grey, or white—the laser struggles to detect enough melanin to work effectively.

Hair thickness also plays a role. Thick, coarse hair absorbs more laser energy, leading to better results. Finer, lighter hair may not respond well, requiring more sessions or a different approach.

What to do?

  • If your hair is too light, the laser may not work. Consider electrolysis, which permanently removes all hair colours.
  • Some clinics offer specialised lasers, such as Alexandrite or Nd:YAG, which may be more effective on certain hair types.
  • Ask your technician about your hair’s suitability before committing to multiple sessions.

2. The Wrong Laser Was Used

Not all lasers are created equal. Different machines work better for different skin and hair types. Using the wrong one can result in poor effectiveness or even skin irritation.

Types of Lasers for Hair Removal:

  • Alexandrite Laser (755nm): This laser is ideal for light to olive skin with dark hair. It works quickly but isn’t suitable for darker skin tones.
  • Diode Laser (810nm) – Effective for various skin tones, including medium to darker complexions.
  • Nd:YAG Laser (1064nm) – The safest option for darker skin tones, as it bypasses surface melanin to target hair follicles.
  • IPL (Intense Pulsed Light) – Often confused with laser but less effective, as it uses a broad spectrum of light instead of a focused beam.

What to do?

  • Ask your clinic what type of laser they use and whether it suits your skin type.
  • If you suspect the wrong laser was used, consult a specialist to reassess your options.
  • Switch to a clinic that offers multiple laser options tailored to different skin tones.

3. Hormonal Imbalances Affect Hair Growth

Excessive hair growth isn’t always due to genetics—hormonal issues can make laser hair removal less effective. Conditions such as:

  • Polycystic Ovary Syndrome (PCOS)
  • Thyroid disorders
  • Pregnancy or menopause-related hormonal changes can cause hair to regrow even after laser treatments.

What to do?

  • If you have excessive hair growth, see a doctor to check for hormonal imbalances.
  • You may need more frequent laser sessions or alternative treatments.
  • Consider medications that regulate hormones if prescribed by a doctor.

How to Improve Laser Hair Removal Results

1. Follow the Right Treatment Schedule

Laser hair removal requires multiple sessions because hair grows in cycles. You may miss the best treatment window if you don’t follow the correct schedule.

Hair Growth Cycle & Laser Timing:

  • Anagen (Active Growth Phase) – The best phase for laser treatment, as the hair is still connected to the follicle.
  • Catagen (Transitional Phase) – Hair detaches from the follicle, making laser less effective.
  • Telogen (Resting Phase) – The hair has fully detached and will fall out naturally, meaning the laser won’t affect it.

What to do?

  • Stick to your clinic’s recommended schedule (usually every 4-6 weeks for body hair and every 6-8 weeks for facial hair).
  • You may need a few extra treatments to catch up if you’ve missed sessions.
  • Don’t stop treatment early—most people need 6-10 sessions for best results.

2. Avoid Sun Exposure

Sun exposure before or after laser treatment can make the skin more sensitive and increase the risk of burns or pigmentation.

Best practices:

  • Avoid sun exposure for two weeks before and after each session.
  • Use SPF 50+ sunscreen daily to protect your skin.
  • Wear protective clothing if you’re spending long hours outdoors.

3. Stop Waxing or Plucking Before Sessions

Many people unknowingly sabotage their laser results by removing hair incorrectly. The laser targets the hair root, but waxing or plucking removes it completely.

What to do?

  • Stop waxing, plucking, or threading at least four weeks before starting laser treatment.
  • Shaving is fine as it preserves the hair follicle while keeping the skin smooth.
  • Use a gentle exfoliator to prevent ingrown hairs, which can affect laser results.

Are Laser Hair Removal Results Guaranteed?

Unfortunately, no clinic can guarantee permanent hair removal because individual results vary based on several factors. While laser hair removal significantly reduces hair growth for most people, some may experience regrowth over time.

1. Factors That Affect Long-Term Success:

✔ Hair Type & Colour – The best results are seen in those with dark, coarse hair because the laser targets melanin (pigment). People with light, fine, blonde, grey, or red hair may not respond as well, as the laser has less pigment to detect.

✔ Skin Tone – Some lasers work better on lighter skin tones, while others are designed for darker skin. Using the wrong laser type can lead to ineffective results or skin damage.

✔ Hormonal Balance – Conditions like PCOS (Polycystic Ovary Syndrome), pregnancy, or menopause can trigger new hair growth, even after successful laser treatments. Hormonal fluctuations may require additional maintenance sessions.

✔ Laser Settings & Technician Expertise – If the laser settings are too low, the treatment might not effectively destroy the hair follicles, leading to regrowth. An experienced technician will assess your hair type and adjust the laser intensity accordingly.

2. What to Do to Improve Your Results?

✔ Choose a reputable clinic with experienced technicians – Ensure the clinic uses TGA-approved lasers suitable for your skin and hair type. Ask about their success rates and the laser types available.

✔ Follow proper pre- and post-care instructions – Avoid sun exposure, shave before sessions, and stick to the recommended treatment schedule to maximise effectiveness.

✔ Manage your expectations – Laser hair removal reduces hair growth rather than eliminating it. Some people may need maintenance sessions every 6-12 months to keep results long-term.

If your laser hair removal results aren’t as expected, you may want to consult your technician about adjusting your treatment plan or exploring alternative hair removal methods.

Laser Hair Removal Not Effective: What Now?

If your laser hair removal results are disappointing, here are your next steps:

1. Book a Consultation with Your Clinic

Discuss your concerns with your laser technician. They can:

  • Assess if you need a different laser type.
  • Adjust the laser settings for better results.
  • Recommend additional sessions if necessary.

2. Try a Different Clinic

Not all clinics use the same technology or have skilled practitioners. If your current provider isn’t delivering results, consider switching.

What to look for in a new clinic:

✔ Uses TGA-approved lasers.

✔ Has trained and experienced technicians.

✔ Offers a free consultation to assess your suitability.

3. Consider Electrolysis for Stubborn Hair

If the laser isn’t working for you, electrolysis is a permanent alternative that removes individual hairs regardless of colour or skin type.

Conclusion

Laser hair removal can be effective, but it doesn’t always work for everyone. Understanding why it didn’t work for you and exploring your options can help you find the best way forward. Whether adjusting your treatment plan, switching clinics, or opting for a different method altogether, smooth skin is still achievable.

If you’re unsure about your next step, book a consultation with a trusted laser clinic in Australia to discuss your options.

Frequently Asked Questions

How Long Should I Wait Before Deciding Laser Hair Removal Isn’t Effective?

After 3 to 4 sessions, you should see noticeable hair reduction. If there is no improvement after 6 to 8 sessions, your treatment plan, laser type, or technician’s approach may need to be adjusted.

If you’ve completed the full recommended sessions and still see regrowth, consult your clinic to determine whether the right laser settings are used. You may need a different laser type or consider electrolysis for stubborn hair.

Can I Fix Bad Laser Hair Removal Results If My Hair Is Growing Back?

You may need extra sessions, an increase in laser intensity, or switching to a more effective laser for your hair type. If hair regrowth is due to hormones, treating the underlying issue can improve results.

Are Laser Hair Removal Results Guaranteed For Everyone?

No. Results vary based on hair type, skin tone, hormones, and the laser technology. The laser works best on dark, coarse hair and may not be effective on blonde, grey, or red hair.

What Are My Next Steps If Laser Hair Removal Doesn’t Work For Me?

If laser hair removal isn’t effective, consider electrolysis, which removes all hair types permanently. You can also try IPL treatments or consult a doctor if hormonal issues are affecting your results.
