Stay Hair-Free & Care-Free with NuAGE Laser!
If you’ve ever wondered how laser hair removal delivers smooth, long-lasting results, the answer lies in science. This advanced technology uses precise light energy to target hair follicles below the skin’s surface — effectively reducing unwanted hair growth over time. But how does it actually work? Let’s break down the science behind one of today’s most popular aesthetic treatments and a few reasons why we’re voted best in town!
The Power of Light and Heat
Laser hair removal works on a principle called selective photothermolysis (say that three times fast!) — a scientific term that describes how specific wavelengths of light are absorbed by certain pigments in the skin or hair.
In this case, the laser emits a concentrated beam of light that’s absorbed by melanin, the pigment that gives hair its colour. The absorbed light energy converts into heat, which travels down the hair shaft and damages the hair follicle — the root structure responsible for new hair growth.
By selectively targeting the follicle while leaving the surrounding skin unharmed, laser technology delivers safe, effective, long-term hair reduction.
The Role of the Hair Growth Cycle
Our hair grows in three main phases:
- Anagen (growth phase) – The hair is actively growing and still connected to the follicle.
- Catagen (transitional phase) – The hair begins to detach from the follicle.
- Telogen (resting phase) – The hair eventually sheds, and a new one begins to form.
Laser hair removal is most effective during the anagen phase, when the follicle is actively producing hair and melanin levels are highest. Because not all hairs are in the same phase at the same time, multiple sessions are needed to effectively target all follicles.
Technology Matters: Different Lasers for Different Skin Types
Modern clinics use various types of lasers to accommodate different hair colours, skin tones, and sensitivities. The most common include:
- Alexandrite Laser (755 nm) – Fast and effective for lighter skin tones.
- Diode Laser (810 nm) – A versatile option suitable for many skin types.
- Nd: YAG Laser (1064 nm) – Ideal for darker skin tones, as it penetrates deeper into the skin with minimal melanin absorption at the surface.
The correct laser wavelength and settings are crucial to ensuring both safety and efficacy. Advanced devices are designed to deliver energy precisely while keeping the skin cool and protected. Here at NuAGE Laser & Skin Care, we use the Rolls-Royce of Laser Technology: CUTERA.
Here are just a few of the reasons why we’re so infatuated with CUTERA:
- It’s the sole medical-grade system that boasts all four devices (IPL, Diode, Alexandrite and Nd: YAG) required for hair removal and a variety of treatments on every skin type from 1-6
- It’s customizable to provide a treatment approach as unique as your skin
- Energy levels remain consistent throughout each session, so no burns and quicker recovery times
- Offers varying levels of penetration for hard-to-reach areas, enabling treatments such as laser hair removal to be up to 10x faster than with traditional systems.
- The machine is ergonomic, making it easy to maneuver and clean for optimal hygiene during treatments.
What Happens to the Hair After Treatment
Following a laser treatment, the treated hairs don’t fall out immediately. Over the next 1–3 weeks, you’ll notice hairs gradually shedding as the damaged follicles lose their ability to hold onto them. With each session, fewer and finer hairs regrow, leading to smoother, longer-lasting results.
Why Consistency is Key
Most people need a series of 10-6 sessions (more for hormonal areas such as the face) spaced several weeks apart to achieve optimal results. This ensures every follicle is targeted during its active growth stage. Maintenance sessions may be recommended once or twice a year to maintain consistent results.
Making an Informed Decision
Here at NuAGE Laser & Skin Care, we cannot advise on whether a laser is a good option, as it is a personal decision based on your willingness to commit to the process.
Our goal is to provide our guests with comprehensive information and a realistic perspective, enabling them to make informed decisions.
We do, however, have some professional feedback.
- Areas with fairer skin tones yield the best results.
- The thicker the hair, the better the results!
- The darker the hair colour, the better.
Laser looks for contrast in colour; therefore, areas where the hairs are thick and dark, while the skin is light, are ideal. The higher the contrast, the better! We do not recommend treating thin hair, as it is often ineffective and can sometimes cause the hair to come in thicker. In some cases, we will not allow treatments if the areas to be treated pose a threat or potential harm.
It is advised that if we begin treating an area, we commit to the suggested series and maintain it regularly when new hair growth appears; otherwise, full hair growth can be expected if treatments are stopped. It is recommended to laser areas that require regular shaving or areas where other hair removal methods are damaging the skin.
Laser is not a permanent hair removal method, as nothing is permanent when it comes to transforming the body. Regular maintenance, from 1-3 times per year, may be required to maintain a hair-free, care-free life. In some cases, hair does not grow back for years, but that is rare. Set expectations at an 80-90% reduction, as nothing is 100%.
For guests with naturally red or blonde hair, expect a 50-70% reduction if some of the hair is dark. Laser does not work on white, grey, blonde, or red hair. In some cases, lasers can be effective on blonde or red hair that contains some brown pigment. When treating blonde or red hair, it is advised to try three treatments. If reduction is visible, continue; if not, stop. We have no way of knowing, as it’s the laser that decides.
How to Get the Best Results
- Tailored Treatments
We pride ourselves on tailoring treatments to ensure each one delivers optimal results.
Which requires:
- Working together as a team.
- Providing us with feedback as to how things are going and what you’re noticing. We need your help, so please pay attention and provide your practitioner with progress updates to ensure we are on track.
Along with the treatment plan, you’ll receive five questions that will be asked at each appointment.
- Guests must monitor changes in hair growth and provide feedback.
- Guessing is expensive, so the more feedback you give us, the more accurate our part will be!
- Timing Appointments
- Treatments must be timed correctly to capture hair at the right stage; otherwise, 2-3 times as many treatments may be required.
- We understand that life can be hectic, and we strive to do our best. So don’t sweat it, but it’s good to know how this all works so that we give ourselves the best chance and save both time and money. That’s what we wish for you. A fun and smooth process to your hair-free, care-free life!
- Maintenance
How can we remain hair-free for life? We suggest monitoring the areas and scheduling an appointment once you have approximately 20% hair growth so that you can undergo treatment. That is because our bodies are constantly evolving and regenerating; therefore, new hair will emerge, and when it does, it, too, will need to be lasered.
Most areas require 1-2 treatments per year to maintain a care-free, smooth-skin life. In some cases, new hair may take years to return, while in others, it may take months. It’s our hormones and lifestyle activities that decipher the new hair growth rate.
Everyone is different; here are some possible causes of regrowth:
- Metabolizes (busy lifestyle, hyper-metabolize)
- Medication and post-trauma
- Age (youth, menopause)
- Hormones (testosterone, PCOS, cortisol/stress, pregnancy)
- Ethnicity (some ethnicities have naturally fuller hair growth)
- Shaving and tweezing regularly
- Fabric rubbing on skin (friction) can cause excess hair growth and ingrown hairs
The hair is at an optimal time for laser treatment after the new batch appears. It will be obvious; you won’t have to guess; at some point you are bare, no hair for a while, and then suddenly they appear; once you see hair poke out, we must come in for laser treatment:
-
- 2 weeks after new hair growth on the body
- 1 week after new hair growth on the face
- It is our guests’ responsibility to monitor and determine when the new batch appears, and to check scheduled appointments to ensure the anticipated timing is accurate.
- Please be advised that our practitioners estimate when the next batch will appear. It is our guests’ responsibility to check and adjust if our estimate is inaccurate, and to update the practitioner if changes are made to the hair growth pattern or the appointment.
- Please be advised that our guests’ experience with hair reduction will differ during the first three treatments compared to the middle treatments (treatments #3-6) and finally at the end of the series (treatment #6 and beyond). New instructions will be provided along the way; that’s what we specialize in: customizing treatments to get maximum results in absolute comfort!
- This is why your feedback is critical to us: it helps us quality-check.
- If treatments are ever ineffective, it is often because they are not completed within the required timeline. At NuAGE, you will receive appointment reminders via email and text one week prior. This is your reminder to check your growth and make any necessary adjustments.
The Takeaway
Laser hair removal isn’t just a beauty treatment — it’s a precise science combining light, pigment, and biology to deliver lasting results. When performed by an expert using the right technology, it’s a safe, effective, and convenient way to reduce unwanted hair and enjoy smoother skin year-round.
