The Dos and Don'ts of Laser Hair Removal
What to Expect and How to Get the Best Results
Laser hair removal has become one of the most popular methods for long-term hair reduction, offering a smooth and hassle-free alternative to shaving and waxing. However, to get the best results, there are key dos and don’ts to follow. In this guide, we’ll cover what to expect from laser hair removal, how different hair growth cycles affect treatment, how long the process takes, and some essential aftercare tips.
The Dos of Laser Hair Removal
✅ Do Choose a Qualified Practitioner
At Glass Face, laser hair removal is performed by a trained medical professional in a reputable clinic. While at-home laser devices exist, they aren’t as powerful as professional-grade lasers and may not yield the same results.
✅ Do Shave Before Your Appointment
Shaving the treatment area 24 hours before your session ensures the laser targets the hair follicle rather than burning surface hair, reducing discomfort. However, avoid waxing, plucking, or using depilatory creams, as these remove the hair root, which the laser needs to be effective.
✅ Do Follow a Consistent Treatment Schedule
Since hair grows in different cycles, multiple sessions are necessary for the best results. Most people need 6-8 sessions spaced 4-6 weeks apart to effectively target all hair follicles.
✅ Do Protect Your Skin from the Sun
Sun exposure before and after treatment can increase the risk of burns, hyperpigmentation, and irritation. Avoid direct sun exposure for at least two weeks before and after your appointment, and always wear SPF 30+ sunscreen on treated areas.
✅ Do Moisturise and Soothe Your Skin
After treatment, your skin may be sensitive or slightly red. Applying aloe vera or fragrance-free moisturisers can help soothe irritation. We will provide you with some aftercare following your appointment.
The Don’ts of Laser Hair Removal
❌ Don't Wax, Pluck, or Epilate Between Sessions
These methods remove the hair root, which the laser targets, making treatments less effective. If you need to manage hair between sessions, stick to shaving.
❌ Don't Use Harsh Skincare Products After Treatment
Avoid exfoliants, retinoids, and chemical peels for at least 48 hours post-treatment, as they can increase irritation.
❌ Don't Expect Immediate Results
Laser hair removal doesn’t provide instant hair-free skin. Treated hairs typically shed over 1-3 weeks, and you’ll notice gradual reduction after each session.
❌ Don't Work Out or Use Hot Showers Right After Treatment
Sweat and heat can irritate freshly treated skin. Avoid intense workouts, hot showers, saunas, and swimming pools for 24-48 hours post-treatment.
Understanding Hair Growth Cycles and How They Affect Treatment
Hair grows in cycles, and laser hair removal is most effective during the anagen (growth) phase, when the follicle is actively producing hair. Since not all hairs are in the anagen phase at the same time, multiple sessions are needed to catch all hairs in this stage.
The Three Hair Growth Phases:
- Anagen (Active Growth Phase) – The best phase for laser treatment. The laser effectively destroys hair follicles in this stage.
- Catagen (Transitional Phase) – Hair stops growing and detaches from the follicle. The laser is less effective at this stage.
- Telogen (Resting Phase) – The follicle is dormant, and the hair eventually sheds. The laser does not work on hairs in this phase.
Since only about 10-20% of hair is in the anagen phase at any given time, you need several treatments to catch all hairs during their growth phase.
How Long Does Laser Hair Removal Take?
Treatment Duration Per Session
The length of each session depends on the treatment area:
- Upper lip – 5-10 minutes
- Underarms – 10-15 minutes
- Legs – 30-45 minutes
- Back or chest – 30-45 minutes
- Intiate areas – 45-60 minutes
- Top to toe – 90-120 minutes
Overall Treatment Timeline
- Most people need 6-8 sessions for optimal results.
- Sessions are spaced 4-6 weeks apart to align with the hair growth cycle.
- Results vary based on skin tone, hair type, and treatment area. Darker hair absorbs more laser energy and responds better, while light, red, or gray hairs may not respond as well.
Additional Useful Tips for Laser Hair Removal
- Be patient – Full results can take 6-9 months, depending on your hair type and treatment area.
- Avoid tanning – Natural or artificial tanning increases the risk of burns and pigmentation changes.
- Stay hydrated – Drinking water and maintaining good skin hydration helps with recovery.
- Expect some regrowth – Hair may regrow finer and lighter, but occasional maintenance sessions (once or twice a year) can help maintain results.
Final Thoughts
Laser hair removal is an effective way to achieve long-term hair reduction, but it requires commitment and proper care to get the best results. By following the dos and don’ts, understanding hair growth cycles, and being patient with the process, you’ll set yourself up for smooth, hair-free skin in the long run.
