What Is Laser Hair Removal?

Laser hair removal uses concentrated light energy to target the pigment in hair follicles. The laser energy is absorbed by the follicle, which may help reduce future hair growth over a series of treatments. It is one of the most popular cosmetic treatments in Australia for long-term hair reduction.

At BLAAH, our team uses medical-grade laser technology that is suitable for a range of skin types. Every treatment begins with an assessment to ensure the correct settings are used for your skin tone and hair type. For a deeper explanation of the science behind it, read our blog post on how laser hair removal actually works.

How It Works

The laser emits a wavelength of light that is selectively absorbed by the melanin (pigment) in the hair follicle. This energy is converted to heat, which may help damage the follicle and reduce its ability to produce new hair. Because hair grows in cycles, multiple sessions are needed to target follicles during their active growth phase.

Your clinician will calibrate the laser settings based on your skin type, hair colour, and the area being treated. A cooling mechanism built into the device helps keep the skin comfortable during the treatment.

Treatment Areas

• Face — upper lip, chin, sideburns
• Underarms
• Arms and hands
• Legs — full or lower
• Bikini line and Brazilian
• Back and chest
• Stomach and abdomen

What to Expect

During the treatment, you will feel a quick snapping or warming sensation as the laser pulses are delivered. Most people find this very manageable, particularly with the built-in cooling system. Treatment times vary depending on the area — a small area like the upper lip may take 15 minutes, while larger areas like the legs may take up to 60 minutes.

After the session, you may notice mild redness or warmth in the treated area, similar to mild sunburn. This typically settles within a few hours.

Pre-Treatment Care

• Do not wax, pluck, or use depilatory creams for 4-6 weeks before treatment
• Shave the treatment area 24 hours before your appointment
• Avoid sun exposure and self-tanning products for at least 2 weeks prior
• Inform your clinician of any medications you are taking, particularly photosensitising drugs

Aftercare

• Apply SPF 50+ daily to any treated areas exposed to sunlight
• Avoid heat treatments, saunas, and intense exercise for 24 hours
• Do not wax or pluck between sessions — shaving is fine
• Keep the treated area cool and avoid hot showers immediately after
• Follow the aftercare instructions provided by your clinician

Who Is It For?

Laser hair removal may be suitable for a range of skin types. It works most effectively on darker hair, as the laser targets melanin in the follicle. Your clinician will assess your skin type and hair colour during your consultation to determine whether laser hair removal is a suitable option for you. We also offer laser skin treatments for pigmentation and redness concerns. Visit our pricing page for treatment costs or check our FAQ page for common questions.

Frequently Asked Questions

How many sessions will I need?

Most people require 6-8 sessions, spaced 4-8 weeks apart depending on the treatment area. Hair grows in cycles, and the laser can only target follicles in their active growth phase, which is why multiple sessions are needed. Your clinician will recommend a treatment schedule during your consultation.

Does it hurt?

Most people describe the sensation as a quick snap or warm flick against the skin. The built-in cooling system helps keep the treatment comfortable. Sensitivity varies by area — underarms and bikini tend to be more sensitive than legs or arms. If you have concerns, speak with your clinician before the treatment.

Is the result permanent?

Laser hair removal is considered a long-term hair reduction treatment, not permanent hair removal. Most people experience a significant and lasting reduction in hair growth after completing a full course of treatments. Some fine or light regrowth may occur over time, and occasional maintenance sessions can help manage this.
