Hair Removal Laser in Iran

Mechanisms for hair removal with light

Light can destroy hair follicles by thermal (due to local heating), mechanical (due to shock waves or violent cavitation), or photochemical (due to a generation of toxic mediators like singlet oxygen or free radicals) mechanisms. Hair removal has been attempted using each of these 3 means. Hair Removal Laser

Hair removal is a vague term that has recently been defined. Temporary hair reduction is defined as a delay in hair growth, which usually lasts 1-3 months, consistent with the induction of telogen. Permanent hair reduction refers to a significant reduction in the number of terminal hairs after a given treatment, which is stable for a period of time longer than the complete growth cycle of hair follicles at the given body site. It has recently been suggested to add another 6 months to this posttreatment observation time (ie, the time necessary for a damaged follicle to recover from the laser injury and reenter a normal growth cycle).

A distinction needs to be made between permanent and complete hair loss. Complete hair loss refers to a lack of regrowing hairs (ie, a significant reduction in the number of regrowing hairs to zero). Complete hair loss may be either temporary or permanent. Laser treatment usually produces complete but temporary hair loss for 1-3 months, followed by partial but permanent hair loss. Histological observations show damage predominantly in hair follicles with large, pigmented shafts, while hair follicles with small (< 25 mm), hypopigmented shafts do not demonstrate any morphological change.

Immediately after laser treatment, the hair shaft shows fragmentation with focal rupture into the follicular epithelium and thermal damage to the surrounding follicular epithelium. The extent of thermal damage is dependent on the pulse width but retains confinement on the spatial scale of the follicle itself. One month later, most follicles are in the telogen phase while others are being replaced by fibrosis and a foreign body giant cell reaction with phagocytosis of melanin. At 1 year, most follicles are replaced by miniaturized hair follicles (dominant mechanism), and some are replaced by a fibrotic remnant. Both of these histological findings produce a permanent clinical reduction in hair.

Anesthesia

Although less sensitive areas (eg, back, legs, arms) can frequently be treated without anesthesia, a topical anesthetic cream is generally used in more sensitive areas.  When treating the upper lip, local or regional anesthesia with intralesional lidocaine may be required. 

Preoperative care 6 weeks before laser treatment is as follows:

• Sunscreen: A broad-spectrum sunscreen is recommended, and sun avoidance must be practiced if hair removal is planned in exposed sites.
• Bleaching cream: A bleaching cream may be prescribed to patients with darker skin types or a recent suntan.
• Plucking, waxing, or electrolysis: The patient should avoid these activities. Research has shown greater hair loss at shaved versus epilated sites, suggesting that light absorption by the pigmented hair shaft itself plays an important role.
• Shaving and depilatory creams: These may be used up to the day before laser treatment. The patient is instructed to shave the area to be treated; however, the area must not be irritated. If the patient is uncomfortable with the idea of shaving the area, a depilatory cream can be used instead.
• Antivirals: The patient should start prophylactic antiviral medications (eg, acyclovir, valacyclovir, famciclovir) when indicated.
• Antibiotics: The patient should start oral antibiotics when indicated (eg, nasal, perianal skin).

Day of treatment and technique

Day of treatment concerns are as follows:

• Cleansing and makeup: The area to be treated should be clean and free of makeup or powder.
• Preprocedure anesthesia: If desired, a thick layer of a topical anesthetic cream (eg, Emla, ELA-Max, Topicaine) can be applied under occlusion (plastic wrap) for 30 minutes to 2 hours before the scheduled laser treatment.

The procedure for hair removal using all of the devices described above can be summarized as follows:

• Skin preparation: Remove all anesthetic cream, makeup, or other skin creams or powders.
• Apply anesthesia, if needed, as described above in the Anesthesia section.
• Visibility: A treatment grid can be applied in order to provide the operator with an outline of the area to be irradiated. A grid may be manually drawn using a white make-up pencil or a yellow fluorescent highlighter. Dark markers or ink should be avoided in delineating treatment grids since darker colors may interfere with the device optics. In the absence of a grid, careful attention must be given to prevent double laser pulsing and missing areas. Visibility can also be increased by a polarized headlamp with a magnifying loupe (Seymour light).
• Treatment fluence: The ideal treatment parameters must be individualized for each patient; test sites can be placed at inconspicuous regions of the area to be treated. The fluence is carefully increased while observing the skin for signs of acute epidermal injury, such as whitening, blistering, ablation, or the Nikolsky sign (forced epidermal separation). In general, the treatment fluence should be at 75% of the Nikolsky threshold fluence.
• Technique: Nonoverlapping or minimally overlapping laser pulses are delivered with predetermined spot size. The largest spot size and the highest tolerable fluence should be used in order to obtain the best results.

Cooling of the epidermis is as follows:

• Cooling gel: If the device is not equipped with a cooling device, a thick layer of cooled clear gel is applied before delivery of the laser pulses.
• Dynamic cooling: Some systems are equipped with a dynamic cooling device that delivers short bursts of cryogen (5-80 milliseconds) on the skin surface automatically prior to delivery of the laser pulse.
• Contact cooling: Some systems use a sapphire-cooled handpiece that is placed in direct contact with the skin. Prior to pulse delivery, the handpiece is pressed firmly against the skin. After delivery, the handpiece is picked up and placed firmly on an adjacent site, until the entire area is covered. The sapphire cooling tip should be wiped clean every 5-10 pulses to remove debris. Between patients, disinfection of the handpiece with a disinfectant solution is mandatory.
• Cold airflow: Some systems use a cooling handpiece that allows a continuous flow of chilled air to the treatment area.

Immediate postoperative changes are as follows:

• Vaporization of hair shaft: The ideal immediate response of treated skin is vaporization of the hair shaft with no other apparent effect.
• Edema and erythema: After a few minutes, perifollicular edema and erythema should be evident.
• Intensity and duration of changes: The intensity and duration of these tissue changes depend on the hair color and density. The fluence should be reduced if signs of epidermal damage develop.

Postoperative care

Ice packs reduce postoperative pain and minimize swelling. Analgesics are not usually required unless extensive areas are treated. Prophylactic courses of antibiotics or antivirals should be completed. Topical antibiotic ointment application twice daily is indicated if the epidermal injury has occurred. Potent topical steroid creams such as clobetasol or fluocinonide may be prescribed for 1-2 days to reduce immediate swelling and erythema.

Avoid any trauma, such as picking or scratching the area. Avoid sun exposure. Use sunscreen with a sun protection factor of 30. Makeup may be applied on the next day unless blistering or crusting has developed. Shedding of hair casts (especially on the face) may be seen; the damaged hair follicle is often shed during the first week after treatment. Patients should be reassured that this is not a sign of hair regrowth.

It occurs for all hair colors (except white) and at any fluency. Blonde-, red-, or gray-haired patients are unlikely to experience a permanent reduction, but hair loss in these patients can be maintained by treatment at approximately 1- to 3-month intervals.

The effectiveness of permanent hair reduction is strongly correlated with hair color and fluency. Research has shown that in the ideal patient with fair skin and dark hair, the probability for long-term hair removal after a single treatment is approximately 80-89%, depending on the device used. A critical threshold fluence is also needed to obtain this effect. Long-term, controlled hair counts indicate an average of 20% hair loss with each treatment, indicating the need for multiple treatments to obtain complete hair removal. A long-term comparison of different lasers (eg, long-pulse ruby, alexandrite, diode) and light sources (eg, intense pulsed light) has indicated that effective long-term hair removal can be achieved with each of these systems.

Regrowing hairs are often thinner and lighter in color, as indicated by measurements of diameter and color of regrowing hairs. This also contributes to the overall cosmetic outcome because the clinical impression of hairiness is defined not only by the absolute number of hairs, but also by the color, length, and diameter of the hairs.

The number of treatments needed to obtain complete, permanent hair removal for different anatomical sites is unknown. Exceptionally, a patient can obtain long-term complete hair removal after a single treatment, while others may respond poorly for yet unknown reasons; however, most patients (80-89%) respond favorably.

Hair removal laser in Iran

If you’re not happy with shaving, tweezing, or waxing to remove unwanted hair, laser hair removal may be an option worth considering.

Laser hair removal is one of the most commonly done cosmetic procedures in the U.S. It beams highly concentrated light into hair follicles. Pigment in the follicles absorbs the light. That destroys the hair.
