Can people with tan skin get laser hair removal? Which type of hair removal is suitable for them?

The life cycle of hair

The life cycle of hair, from growth to shedding, varies depending on the area of ​​hair, but generally it can be divided into three stages.

• Anagen phase

The hair growth phase is the stage where hair is fully grown or developed. This is the most complete stage of all hair. About 80% of our body hair is in this phase, and a single hair can live for 2-6 years, or on average 3 years.

• Catagen period

The hair follicle degeneration phase is when hair growth stops and it enters the shedding phase. After laser hair removal, the hair remains in this phase for approximately 1-2 weeks before growing back.

• Telogen phase

The hair shedding phase takes approximately 5-6 weeks before hair grows back, but this depends on genetics and the density of each individual's hair.

 Laser treatment for people with tan skin.

During laser hair removal, the laser device sends light energy to the skin, targeting pigment cells called melanocytes. These melanocytes, acting as light-conducting cells in the hair follicle, absorb the laser energy, generating heat that destroys the hair root.

Melanocyte 

Melanin is a pigment produced by skin cells called melanocytes. It is a high molecular weight pigment with colors ranging from reddish-brown to black. Furthermore, melanin, the pigment of the skin, eyes, and hair, is synthesized from the amino acid tyrosine in melanocytes before being transported to the skin layers.

Melanin can be divided into two types:

1. Eumelanin contains nitrogen and is black in color. It is generally found as a pigment in human skin, such as in hair, body hair, and skin cells. Eumelanin is divided into two types:

• Black eumelanin gives a black color when there is a high concentration of this pigment, and a gray color when the amount is low.
• Brown eumelanin gives hair a brown color when present in high concentrations, but if present in low amounts, it will result in a light brown or blonde color. Brown eumelanin is more common in Europeans.

2. Pheomelanin, containing nitrogen and sulfur, is a white pigment considered a light tone. Its main component, carotenoids, is the orange-red tone. This is clearly visible in hair, fur, and skin.

Therefore, people with tan skin have more melanocytes, which makes them more prone to burns than those with lighter skin tones. This requires more treatment sessions and the laser must be administered in small increments to prevent burning, inflammation, or damage to the skin in the treated area.

Can people with tan skin get laser hair removal?

People with tan skin can definitely have laser hair removal. The laser hair removal machine at Romrawin Clinic is suitable for all skin tones and all body hair. It's gentle on the skin, painless during treatment, doesn't cause skin burns, and also stimulates collagen production, resulting in brighter skin tone.

After laser hair removal, will the hair grow back?

Generally, laser hair removal results in slower hair regrowth, thinner and lighter-colored new hairs, and fewer overall growth. With repeated laser treatments to disrupt hair growth, hair will eventually stop. A minimum of 5-8 sessions are recommended, spaced 4-6 weeks apart.

How many sessions are needed for permanent laser hair removal?

For permanent hair removal, multiple laser hair removal sessions are required to completely eliminate hair. This is because hair grows through three phases: Telogen, Catagen, and Anagen.

Laser hair removal must be performed on hair in the Anagen phase, which is the hair growth phase. If the hair is in any other phase, it cannot be completely removed. You must wait for the hair to reach the Anagen phase before it can be completely lasered off. After removal, the hair enters the Telogen phase and gradually grows more slowly until it reaches the Catagen phase. With continued laser treatment, the hair will eventually enter the Anagen phase until no more hair grows back.

What is laser hair removal?

Laser hair removal is a method of hair removal that uses thermal energy from a laser beam to target the hair follicle. The hair follicle absorbs the light energy and converts it into heat, destroying the surrounding tissue containing pigment cells. This destroys the hair follicle, hair root, and other tissues responsible for hair production, preventing the production of stem cells that cause hair growth. As a result, the hair regrowth cycle is slowed down. Newly grown hair will be thinner, lighter in color, and less numerous. With repeated laser treatments to destroy hair production, hair elimination will eventually occur.

Laser hair removal for visible results.

Effective laser hair removal requires a sufficient wavelength range, as wavelength directly affects hair removal. A sufficiently high wavelength allows the energy to penetrate deep into the hair follicle and destroy it effectively.

Current laser hair removal methods offer different advantages, but several factors must be considered. These include skin color, hair color, and hair density in the treatment area, as well as the experience and expertise of the doctor. An experienced laser hair removal doctor can plan a treatment tailored to your specific needs, adjusting the energy intensity and wavelength to effectively and completely remove hair.

How many types of laser hair removal are there, and who is it suitable for?

Currently, various laser technologies are used for hair removal, the most popular of which are as follows:

IPL (Intense Pulsed Light)  

IPL devices use light energy, not lasers. Their wavelengths range from 420 nanometers to 1,200 nanometers. The beam spreads more widely than lasers, which use a single wavelength. Because the beam is so wide, surrounding skin areas are also affected, causing redness, swelling, and some discomfort during treatment (though it's usually tolerable). While IPL hair removal uses the same principle as other lasers—using concentrated light energy to destroy melanin cells in the hair follicle—it doesn't completely eliminate all hair from the root. Therefore, hair regrowth in that area will be noticeable soon after treatment.

• Suitable for: People with fair skin.   
• Popular areas for treatment: face, legs, back, bikini area, underarms, and sensitive areas. 

Alexandrite Laser

The Alexandrite Laser is a hair removal technology that uses a ruby ​​crystal as a laser beam with a wavelength of 755 nanometers. This laser beam, which uses an alexandrite crystal as a medium to produce light, penetrates deeper and targets pigment more effectively than long-pulsed ruby ​​lasers and IPL. It can deliver laser energy to the mid-layers of the skin to destroy melanin cells in hair follicles. Although it's one of the first lasers with good hair removal efficacy, it's not suitable for all skin types. Alexandrite Laser is particularly suitable for very fair skin, making it more appropriate for Europeans than Asians.

• Suitable for: People with fair or yellowish skin tones. Not suitable for people with blonde or red hair.
• Popular areas to treat: Large areas such as the legs.

Diode Laser

Diode laser hair removal technology uses laser energy waves with a relatively wide range of wavelengths, ranging from 800-810, 940, and 1064-1350 nanometers. Currently, the most popular wavelength ranges consist of two main ranges. 

1. Wavelength 810 nanometers 
2. Wavelength 940 nanometers 

Diode hair removal uses heat energy to penetrate deep into the skin, destroying melanin cells in the hair follicles and hair roots. It also rapidly destroys the hair-producing structures, such as the capillaries that nourish the hair roots and tissue, within just 10-20 minutes. This prevents the skin from producing stem cells that cause hair regrowth, effectively slowing down the growth of new hair, reducing its quantity, and eventually leading to hair loss.

• Suitable for: People with fair to medium skin tones, but not suitable for those with tan skin. Those with thick, dark hair will see better results than those with light-colored hair.
• Popular areas for treatment: Arms, legs, and large areas. Laser treatment is not suitable for the face or small areas.

YAG Laser

The AG Laser at Romrawin Clinic is a long-pulse Nd:YAG laser, very popular in Thailand and the latest technology. It uses a wavelength of 1,064 nanometers, an energy wave that penetrates deep into the skin and fat layers to destroy melanin cells in hair follicles. The energy is delivered at a frequency capable of destroying hair roots without damaging surrounding skin during treatment. During the procedure, a cooling spray is released to cool the upper skin layer and protect the treated area.

• Suitable for: People with tan or dark skin tones. Can be used on all skin types. 
• Popular areas for treatment: Hair can be removed from various parts of the body, such as underarms, upper lip, bikini area, arms, and legs, etc.

Which type of laser hair removal should you choose? Since pigments absorb laser energy from lower wavelengths better than IPL and Alexandrite Laser, they are not suitable for Asians with darker skin tones. The pigment may absorb too much laser energy, causing burns. Therefore, YAG lasers and Diode lasers are more suitable for Asians.

Is laser hair removal dangerous?

The laser used is highly safe, does not cause cancer, and is not as harmful as many people worry. The YAG Laser used at Romrawin Clinic is a long pulse Nd:YAG laser system, which is certified by the Thai Food and Drug Administration ( อย.) and the US Food and Drug Administration (US FDA). Therefore, it is safe and effective for hair removal, especially suitable for Asian skin. It removes hair from the root and is painless. 

• Possible side effects include skin burns if too much energy is used. After laser treatment, there may be redness and swelling around the hair follicles, which will subside on its own within 1-2 days.

Does laser hair removal really work, and how long does it take?

After laser hair removal, hair growth will slow down, become finer, thinner, and lighter in color. After the first laser treatment, the doctor will schedule the next treatment in one month, the third in about one and a half months, and the fourth in two months. Some women see significant hair loss after only four treatments, while others may need up to eight treatments, depending on the individual.

What preparations should be made before and after laser hair removal?

No special preparation is needed before laser treatment, but it's recommended that you refrain from plucking or trimming your hair beforehand. At Romrawin Clinic, the staff will shave your hair for you. After treatment, avoid swimming in chlorinated pools and refrain from taking hot showers for about 3 days, as this may cause a burning sensation.
