One of the methods to remove excess hair is a diode laser device.
Diode laser hair removal is one of the easiest ways to permanently remove excess hair.
Slight discomfort and pain may be felt when the laser beam is placed on the treated area, but local anesthesia is not required.
Diode lasers are the best type of laser hair removal that effectively removes excess hair from all skin types with fewer treatment sessions.
Unlike previous lasers, to effectively remove excess hair, it is not necessary for the laser to pass through one area several times, thus shortening the treatment time.
What is a diode laser?
Diode lasers use semiconductor technology. Which produces light in the visible infrared range.
In this method, a beam of light is shone in a narrow range on the desired chromophores in the skin.
The diode laser wavelength is long and penetrates deeper into the skin compared to other laser devices such as ruby and alexandrite lasers and has the highest melanin absorption.
This feature has made the diode laser one of the best methods to remove excess body hair and can be used for all types of hair and skin and for different parts of the body.
This type of laser uses wavelengths of 800 to 810 nm to remove excess hair.
The absorption of these wavelengths in black melanin of hair follicles is less than Alexandrite laser but more than IPL and Nd – YAG lasers.
Due to the wide range of pulse length and energy settings, the diode laser has many applications and is also very effective in removing excess hair of the Iranian race and people with dark skin.
Did you know that people with porphyria also have to underline this treatment because of the reaction they show to the facial laser?

The operating system of the diode laser in the permanent removal of excess hair, includes the use of a batch of concentrated light and heat
Which focuses directly on the hair follicles as well as the melanin inside them.
The pigment is removed by absorbing the laser energy and prevents hair growth in the hair follicles affected by the diode laser.
The laser energy is applied directly to these follicles and at the same time does not damage the surrounding skin.
In fact, the diode laser emits the energy of absolute red light that is absorbed by the hair melanin.
This light is converted into heat at the roots of the excess hair, removing the cells responsible for hair growth.
Absolute red light is the most effective light for destroying hair cells, and this makes the diode laser an effective treatment for hair removal.
Diode laser treatment requires several sessions of treatment. The duration of each laser treatment session is short and the recovery period is short.
This laser is suitable for removing thick and coarse hair and is usually very popular among men
Because the diode laser method is effective for removing back and chest hair from men, most of whom are dissatisfied with the excess hair in this area.
Use of diode laser in hair removal
Areas of the body that are most often treated with this method are:
• Underarm hair
• Waist hair
• Chest hair
• Hair on the legs
• Bikini hair (men and women)
• Hair above the lips
• Chin hair
The Benefits of Diode Laser in Hair Removal
• Has a greater penetration depth than alexandrite
• Risk reduction due to uniform pulse
• Surface cooling
• Can be used on dark skin
The diode laser has a long wavelength and penetrates deep into the skin in a completely safe way.
• More surface hair is removed at the same time.
• The duration of treatment and recovery is short.
• The wavelength range is not specific and can be changed and the wavelength can be adjusted according to need.
This method is less likely to damage the epidermis than other methods.
In addition, other benefits of the diode laser for hair removal include the following:
It works faster
Hundreds of excess hairs are targeted in each beam of light emitted by the diode laser device.
Removing facial hair follicles takes only 10 minutes, and this time for larger areas is barely half an hour, which is definitely a faster way to remove excess hair.
Fewer treatment sessions
Because the diode laser device targets a large number of hair follicles each time, the number of sessions required to complete the treatment is greatly reduced.
The number of sessions required depends on the color of the excess hair and the skin color of the area.
Diode lasers are a completely painless procedure, and only in some people, if the diode laser light is too focused on the highly sensitive areas, it may feel a slight burning sensation.
Who can get rid of excess body hair with diode laser method?
Due to the fact that the diode laser is a safe method and has long-term results, it is suitable for almost all people with all skin types.
People with lighter skin and darker hair need fewer sessions to achieve the desired result.
But darker skin needs more treatment. Darker skin absorbs more energy
So for people with dark skin, we use less energy to prevent injury.
To prevent complications and damage to the skin, it is necessary not to be exposed to sunlight for several weeks after the laser.
There is no specific technology for removing gray or blonde hair
But we can get rid of brown, light and red hair more effectively. This will take more time.
How many sessions of diode laser treatment are needed to remove excess hair?
Most people need an average of 6-10 sessions to remove the main part of their hair.
This treatment works by targeting the hair during its active growth phase, and because the hair has grown at different stages of its growth cycle,
It will take several sessions to remove all the follicles in the area. The outcome of treatment depends on the area being treated, gender, age and hormone levels.
Necessary preparations before laser hair removal
Excess hair in the treated area should be shaved the day before treatment.
Avoid tanning (either naturally or with a special bed تا) for up to 4 weeks before laser hair removal.
• Up to 4 weeks before laser hair removal, avoid removing excess hair from the area using tweezers, wax, trimmer or electrolysis, but shaving with a razor is allowed.
Avoid using Accutane (to treat acne) for up to 6 months before laser hair removal.
• Do not use makeup, lotion, body oil or perfume and do not hang jewelry before your laser appointment.
• If you have a history of herpes virus or pest, get proper medication the day before the laser hair removal session to prevent most of the symptoms from coming out.
• Before treating your dermatologist, please inform your doctor of any medication you are currently taking or up to 4 weeks before your treatment session.
Certain medications may make your skin more sensitive to both sunlight and laser light.
For added safety, your doctor should be aware of any medications you are taking.
Are laser therapy sessions associated with pain?
Hair removal with a diode laser device is one of the convenient ways to permanently remove excess hair.
A slight pain may be felt during treatment sessions, which is normal. The amount of pain actually depends on how sensitive the person is and is not the same for everyone.
To reduce the pain caused by the laser, one can use some local anesthetic creams before the session.
The use of cooling during treatment also reduces the pain caused by laser contact with the body.
What are the differences between a diode laser and an alexandrite laser?
Both types of lasers are frequently used in the treatment of hair loss, the diode laser is newer in the market than the alexandrite laser.
As mentioned earlier, the diode laser operates at 800 or 808 nm.
This longer wavelength allows for deeper penetration into the skin, theoretically avoiding radiation contact with melanin in the skin epidermis.
As a result, the hair follicle is directly targeted.
Theoretically, longer wavelengths help prevent skin damage and skin discoloration, which can occur in shorter wavelength lasers.
The diode laser works well on thick and dark hair and is also a good option for back and bikini hair.

But the alexandrite laser operates at a wavelength of 755 nm, which is shorter than the wavelength of a diode laser.
And is effectively used in laser treatment of hair loss for species I-IV.
Shorter wavelengths are theoretically more effective on light skin than on dark skin.
Larger areas can be covered with the larger target point size of the Alexandrite laser, so this laser is an almost better option for larger areas such as the back and chest.
Although alexandrite laser treatment may have temporary and harmless side effects (skin redness and red bumps),
And the diode laser may be a little more painful, both lasers have yielded impressive results.
Therefore, it can be said that both types of lasers have equal performance (somewhat better performance of diode lasers) for darker hair.
And different skin types in the I-IV range on the Fitzpatrick scale.
If you are in this range you will most likely not find a difference in the results of these two types of lasers.
Is there a ban on laser hair removal in pregnant women?
Diode laser aftercare
Redness and swelling around the treated area is normal and causes a sunburn-like condition.
Which should resolve within a few hours or days after treatment. Putting ice and cold water compresses will help reduce the problem.
Avoid exercise for at least 12 hours before the redness subsides.
Avoid saunas, jacuzzis and hot showers for at least 12 hours before the redness subsides.
If the treated area is not red, a hot shower is allowed. If there are signs of redness while showering, stop showering immediately and place on the ice area.
• Do not use any stimulants such as glycolic acid, retinoids, etc. for up to 7 days after treatment.

• Do not use natural tanning or solarium during the entire treatment period and up to 1 month after the final treatment.
Do not use makeup, lotion, body oil or perfume between treatment sessions, if necessary, the only acceptable way to shave excess hair is shaving with a razor.
During the day, use a sunscreen with SPF 30 to protect against UVA / UVB light and contain physical blockers such as zinc oxide and titanium oxide.
If you are exposed to sunlight, use a sunscreen with SPF 50.
It may take 1 to 3 weeks for dead hair to fall out of your follicle.
It is best to gently exfoliate the treated area 2-3 times a week after your treatment. After exfoliation, moisturize the skin to help repair it.

Side effects of diode laser
Due to the high intensity of the light used, everyone in the treatment room should wear safety glasses to prevent eye damage.
Immediately after treatment, the effects of redness and minor burns or hives may appear in the treated area
Rarely, small blisters may appear from exposure to too much sunlight.
Temporary darkening or lightening of the skin in the treated area may occur.
If the instructions after laser hair removal are not followed carefully, the skin discoloration will be permanent.
In some people, there are no side effects, and these skin reactions usually go away in a matter of hours or days.
In addition to the above mentioned, the possible side effects of laser hair removal can include the following:
One of the reasons that itching occurs on the surface of the skin after laser treatment is the removal of the surface of the hair follicles, which increases as the itching becomes empty.
It is recommended that you never scratch the area with your hands if this complication occurs, as there is a possibility of skin blemishes.
• Inflammation of the skin:
Some sensitive skin may develop skin inflammation from a few hours to a few days when using a diode laser, which will go away after a while.
• Bleeding on the surface پوست:
Areas with thinner skin than other parts of the body are more prone to bleeding.
It is better to use a diode laser device for a shorter period of time in these areas to avoid this problem.
• Changes in pigments:
It has been observed that in some people, after the laser treatment sessions, the skin pigments will change and cause blemishes.
Depending on the skin and the reaction of the person, these spots may be permanent or temporary.
In general, a small percentage of people suffer from diode laser complications, but this percentage of people who do not exceed 5%
Before performing laser treatment to remove excess body hair, they should explain their history of previous diseases and body reactions to a dermatologist.
Because from the doctor’s point of view, these people may not be able to be treated for laser hair removal
Therefore, your doctor should consult your doctor during the consultation session to prevent possible complications.
Provide you with information about possible side effects and care after laser hair removal.
