A. How Laser Hair Removal Works
1. Hair removal results that last
Permanent hair removal has quickly become one of the most popular and sought after cosmetic procedures worldwide. With advanced light-based treatments, patients no longer have to deal with lengthy and irritating removal methods, such as shaving, waxing and tweezers, which require constant maintenance.
Today, most patients with unwanted hair are looking for more permanent removal methods, such as laser hair removal or IPL. These treatments use concentrated light rays to selectively destroy hair follicles and prevent future hair growth. As a leading manufacturer of light-based technology, Astanza offers the latest and most innovative laser hair removal systems that leading hair removal suppliers across the country rely on.
2. Procedure overview
Although different light-based technologies are used to remove hair, all treatments are the same. During a treatment, bright flashes of light are emitted on unwanted hair. The light penetrates the skin and selectively reaches the melanin in the hair follicles. The pigment absorbs light energy and effectively destroys hair. Depending on the size of the handpiece used, several strands of hair can be treated at the same time.
Several sessions are required to target the hair follicles as they grow. Most patients will need at least 4 to 6 treatments to obtain permanent and long-lasting results. Improvements may be needed over time. Patients should see results after the first treatment – the hair is thinner and weaker and the skin is smoother. The results become clearer and more impressive with each subsequent treatment, until all follicles are destroyed and continuous hair growth is successfully stopped.
3. Who can get light-based hair removal?
Women and men are very likely to get laser hair removal. Most women seek treatment to remove hair from the forearms, groin and legs, while men are more interested in treating hair on the back and neck.
When the hair removal laser was introduced, the procedure was originally intended for patients with fair skin and dark hair. However, newer technologies, such as Astanza systems, are able to safely and effectively treat patients of all skin types and hair colors.
4. Different types of light-based hair removal
Today, a wide range of aesthetic technologies based on light is used to perform hair removal treatments. Laser hair removal and IPL treatments are two of the most popular methods. Astanza offers IPL (EthereaMX) and diode (ReSmooth) laser hair removal technologies trusted by doctors and patients worldwide.
What is the difference between laser treatment and IPL? Lasers generate a single wavelength of concentrated light to specifically target the melanin in the hair. Diode technology typically uses a wavelength around 800 nm to 810 nm. Intense pulsed light (IPL) creates a broad spectrum of light from about 550 nm to 1200 nm instead of a specific wavelength to reach the melanin in the hair. Both treatments target the hair efficiently to obtain optimal results and work in essentially the same way.
B. How Does Laser Hair Removal Work?
Let’s face it, although we all want smooth, hairless skin, no one likes to waste time growing, shaving, pulling or bleaching their hair. It’s time for you to do something more enjoyable. What is the alternative? Laser hair removal – a safe and effective procedure that offers permanent hair removal.
1. What is a laser
- Did you know that
- The three stages of hair growth
To understand how laser hair removal works, you need to understand the different stages of hair growth. Hair has 3 different growth stages and not all hair grows at the same time. That’s why you sometimes found that if you shaved it, your hair would grow back about a week later. Usually, this is not the same hair that you shaved a week ago, but the hair from a different follicle that was at a different stage of growth.
LASER is an acronym that means “amplification of light by stimulated radiation emission”? The definition of laser is an “electronic device that, by amplifying photons with more energy, creates an intense monochromatic beam of light through collisions with other photons. The laser beams can travel long distances without dispersion and carry huge amounts of energy. ”
a. Complicated right?
Well, basically, a laser is a very powerful and very focused beam of light. Lasers are used in a wide variety of applications, from industrial to communications and mapping. Laser hair removal is based on lasers specially developed for medical purposes that can be safely applied to human skin.
2. The three different stages of hair growth are:
- Anagen – the active growth phase. At this stage, the lower part of the hair follicle (the bulb) is connected to the dermis and its blood supply through the dermal papilla.
- Katagen – the transition phase. The hair follicle begins to die and enters the catagen phase
- Telogen – the resting phase. At this stage, the remnants of the hair bulb are inactive and the hair that is caught falls easily.
3. How do lasers remove hair?
Laser hair removal works because the light from the laser beam can be converted into heat. The light is attracted by the pigment (melanin) of the hair. The dark pigment absorbs light and converts it to heat. The heat then affects the hair follicles to prevent hair growth. To destroy a hair follicle, the hair follicle bulb, where blood oxygenates the hair to grow, and the stem cells responsible for hair regeneration, must be destroyed. To do this, a temperature of approximately 70 degrees must be reached.
The darker and thicker the hair, the more pigment it retains and the more light it absorbs. Therefore, it is important not to shave or epilate the hair before treatment, because if there is no hair there, the laser light will not be able to treat that hair follicle. To summarize again: light is emitted, then absorbed by the hair pigment, travels through the hair and is converted into heat and destroys the root. The hair is destroyed and does not grow back! It is so simple and effective.
4. Is laser hair removal permanent?
There are 3 main factors that can influence whether or not you get permanent hair removal. Only hair in the growth phase (hair in the anagen phase) can be successfully treated, but not all strands grow at the same time. For example, at a certain point in time in our body, only about 20-40% of hair grows (in the anagen phase), the others are in transition or in the resting phase. Because of this, several treatments are needed to preserve the various hair strands as they enter the growth stage. Treatments are carried out every 8 weeks for the body and 4 weeks for the face.
Second, only pigmented hair can be treated. If you have white, gray, blonde or red hair, it is important to understand that they are not reactive, as this hair does not contain a dark pigment that retains light. As a result, the laser cannot generate enough heat to destroy the hair. The thinner and lighter the hair, the more difficult it will be to get permanent hair removal because the hair contains less pigment.
The thicker and darker the hair, the more pigment it contains, which causes the light to be absorbed, turns into heat and reaches a temperature around 70 degrees, thus destroying the hair root. If this temperature is not reached, the treatment will only damage the hair, causing lighter and thinner hair to grow back. In that case, the hair follicle will not be destroyed effectively.
And the third factor is the color of the skin. The lighter your skin, the greater the fluency (intensity) with which you can be treated. If your skin is darker, the therapist will need to use less fluency to treat you. This is because laser light does not know the difference between the pigments in your hair or your skin. Therefore, when you get a tan, the risk of burning your skin increases. It is best to keep your skin as clear as possible, so that you can be treated with a higher fluency. And that is why you need to stay out of the sun while tanning, use sunscreen every day and start treatment when your tan disappears.

C. Laser Hair Removal: Permanent or Temporary Fix?
1. Is it really permanent?
In short, no. Laser hair removal heats hair follicles to prevent new hair growth. This puts the hair follicles in a dormant state for a long period of time – much more than shaving and shaving. When the hairs grow back, they are lighter, thinner and in lesser number.
Although the procedure is often presented as a form of “permanent” hair removal, laser treatment only reduces the number of unwanted hair in a specific area. Unwanted hair is not removed completely. According to the Mayo Clinic, this hair removal option works best on people with light skin tones and darker hair. For best results, the American Association of Dermatology (AAD) recommends that a certified dermatologist perform the procedure.
2. How Laser Hair Removal Works
Laser therapy uses high-temperature laser beams as a moderate form of radiation. During the process, these laser beams heat up and damage the hair follicles. The hair follicles are just below the skin. You are responsible for producing new hair strands. When follicles are destroyed, hair production is temporarily disabled. In contrast, tweezers, shaving and shaving remove all hair above the surface. These methods do not target hair-producing follicles.
The AAD considers the following areas to be suitable for laser hair removal:
- Come back
- Bikini line
- Face (except around the eyes)
This form of hair removal is best for darker hair colors in light skin tones. This is because lasers target the hair’s melanin (color). Even if some hairs are not removed, lightening their color can decrease the appearance of hair on the skin. Some of your hair may also fall out a few days after the first treatment.
In general, laser hair removal is a relatively quick process. Smaller areas, such as the upper lip, may take only a few minutes. Larger areas of hair removal, such as the back or chest, can take an hour or more. If your dermatologist first applies a topical analgesic gel (anesthetic), you can stay in the office for another hour. Despite the high success rate of laser hair removal, hair follicles end up healing. This leads to new hair production. To get the best possible results, you will need to do several treatment sessions.
3. Why follow-up sessions are necessary
Follow-up treatments are necessary to get the most out of laser hair removal. The exact number of maintenance laser treatments varies from person to person. Most people need four to six sessions of laser therapy, according to the Mayo Clinic. You will also need to reduce them by six weeks at a time – this means that the entire treatment cycle can take up to nine months. You will probably notice less hair after each session. The remaining or regenerated hair is lighter in texture and color. The AAD estimates that the number of hairs decreases by 10 to 25 percent after their first session. The rate of reduction will improve after that, but it will also vary.
For best results, you will likely need occasional maintenance sessions. This helps to prevent hair follicle regeneration. Depending on your individual needs, you may need a maintenance session once or twice a year after your first round of laser treatment. The schedule for each session corresponds to the initial treatment of laser hair removal. In general, the time depends on the treatment area. If you touch up only a few small areas during maintenance sessions, your commitment may be shorter.
Although laser hair removal is not exactly permanent, it is still one of the best ways to slow hair growth for a long period of time. Other long-term hair removal options that you can discuss with a dermatologist include electrolysis and needle epilators. If you do not want to bear the costs of medical procedures, which are not permanent in any way, there are numerous options for hair removal at home.
Talk to your dermatologist about:
- Epilators with tweezers
- Wax or sweeten
- Proper shaving techniques
Miniature versions of laser hair treatments are available on the market for home use, but their safety and effectiveness are unclear. The Food and Drug Administration does not regulate laser hair treatment at home as a medical device, so it is not tested as such. It is best to leave the laser hair removal to a specialist.
