Why isn't My Laser Hair Removal Working?

You booked the course, kept every appointment, shaved like clockwork yet those stubborn hairs refuse to disappear? You’re not alone. Every week our therapist meets women who feel they’ve done “everything right” only to wonder why their laser hair removal isn’t working. Before you call it quits or write laser off as a gimmick, let’s pause.

‍

Effective laser hair removal is a partnership between your skin, your hair, and your clinic’s technology and technique. When that trio falls out of sync, results stall but the good news is they can almost always be brought back on track.

‍

This guide walks you through the eight most common reasons treatments under‑deliver and the proven fixes that get progress moving again. If you’re a woman who is fed up with persistent bikini-line growth or a trans woman dealing with facial dysphoria, or anyone who simply expected smoother skin by now, we’ve got you.

1. Hair and Skin Type Compatibility

Laser energy is attracted to pigment. Traditional lasers struggled when hair was very light or skin was very dark, but modern multi‑wavelength platforms (such as the Soprano Titanium we use at Laser Me Out) can safely treat a far wider range of complexions. Even so, hair that is grey, red, or very light blond may respond more slowly than dark brown or black hair.

2. Treatment Schedule Consistency

Hair grows in cycles. Only follicles in the active (anagen) phase can be disabled during a session. If appointments are missed or spaced too far apart, new batches of anagen hairs will be missed, delaying overall progress.

3. Pre‑Treatment Preparation

Shaving leaves the root in place for the laser to target; waxing, plucking and epilators remove that root completely. Incorrect preparation is one of the most frequent causes of patchy results and lingering regrowth.

4. Sun or Fake‑Tan Interference

Ultra‑violet exposure stimulates extra melanin in the skin. Tanned skin absorbs more laser energy, making treatments less efficient and increasing risk of irritation or pigment change. Self‑tanners cause a similar issue by depositing artificial pigment on the surface.

5. Hormonal Influences (Including PCOS)

Hormones such as testosterone, oestrogen, and insulin‑like growth factors control the thickness and distribution of body hair. Conditions like PCOS, menopause, or certain contraceptives can drive new hair growth even while a laser course is in progress.

6. Medication and Active Skincare

Photosensitising medicines (for example some antibiotics, isotretinoin, or high‑dose vitamin A derivatives) can make the skin more reactive to heat. Topical activities such as strong retinoids or acids may also increase post‑treatment sensitivity, altering the settings your practitioner can safely use.

7. Technician Skill and Equipment Quality

Older single‑wavelength machines may not penetrate as evenly or cool the skin as effectively as newer models. Equally, technicians who lack formal laser qualifications may choose conservative parameters that fail to disable the follicle fully.

8. Expectations Versus Reality

Laser hair removal offers permanent reduction, not a 100 percent guarantee of zero regrowth. Most people achieve 80‑90 percent long‑term reduction after a properly executed course, with occasional maintenance top‑ups.

Fix‑It Checklist: Eight Steps to Get Your Results Back on Track

1. Book a technology check‑up. Ensure your clinic is using a modern, multi‑wavelength diode platform (for example, Soprano Titanium) and that the settings are appropriate for your skin type.
2. Commit to the schedule. Aim for sessions every 4–6 weeks on face and every 6–8 weeks on body areas until your practitioner advises otherwise.
3. Shave but do not wax 24 hours before each session. Stop all root‑removal methods (wax, thread, epilate) for at least four weeks before restarting a laser course.
4. Stay sun‑safe. Avoid tanning beds, deliberate sunbathing, and self‑tan products for two weeks before and after each session. Apply SPF 30+ daily on exposed areas.
5. Review hormones. If you have PCOS or suspect hormonal imbalance, consult your GP or endocrinologist. Combining medical management with laser yields far better control of regrowth.
6. List every medication and active product. Tell your technician about oral antibiotics, isotretinoin, retinol, glycolic acids, and any new prescriptions before each appointment.
7. Request a patch test with updated parameters. If progress is slow, a higher fluence or different pulse width may be necessary. A controlled test patch confirms safety.
8. Adjust expectations. Remember that total clearance is rare; plan for one or two yearly maintenance sessions after your initial course, especially on hormonally sensitive areas such as the face.

Frequently Asked Questions

Can laser hair removal completely fail?
True treatment failure is rare. Most setbacks are linked to preparation, scheduling, or equipment issues and can be corrected.

Does PCOS mean laser will never work for me?
No. You may need more sessions and occasional maintenance, but consistent laser combined with medical management delivers excellent improvement.

I stopped laser a year ago. Can I restart?
Yes. Book a reassessment so we can confirm your current growth pattern and build a tailored top‑up schedule.

Are all lasers basically the same?
No. Multi‑wavelength diode systems with integrated cooling, such as Soprano Titanium, provide faster, safer, and more comfortable treatments across all skin types compared to many older machines.
