What does laser hair removal feel like?

It is very important to protect the top layers of the skin from becoming too hot during a laser treatment. Many lasers have different cooling mechanisms to protect the top skin, however, none of them can match the cooling protection which is provided by the Light Sheer's contact cooling Chill Tip. The tip of the Light Sheer is made of saphire which conducts heat very quickly. This saphire tip is constantly cooled to 5 degrees by the control of the laser's computer. When the tip of the laser is placed on the skin, it cools down the upper layer of the skin and protects it from getting too hot. This allows us to use higher energies at a safe level, and thus obtain better results.

The root of the problem Hair grows in cycles, and many factors influence its growth, Age, ethnicity, medications, hormones levels, and even location of the hair on the body influence the length, coarseness and colour of hair . Anagen is the active growing phase in which the hair bulb is intact. The hair grows in both directions, upward and downwards Catagen is the regression phase when the lower part of the hair stops growing but is not shed, and the body absorbs the lower third of the follicle. Telogen is the resting phase. The hair bulb is no longer present and is now a club hair which will fall out or be pushed out of the follicle by the new anagen growing hair .

Laser roots it out for good

Laser hair removal is a non invasive procedure, by which unwanted hair are removed from any part of the body by utilizing a long pulsed laser.

The laser parameters are carefully defined by studying the anatomy of the hair follicle and precisely matching the laser light and pulse duration to the follicle size, depth and location to inhibit the re-growth of the hair. Laser hair removal technique helps in facial hair removal and permanent hair removal.

Laser hair removal is performed by a specially - trained laser technician or a doctor, who directs the light of a long pulsed laser onto the skin. Since other hair will enter their growth cycle at different times, several sessions are necessary to destroy all the follicles in a treatment area.

Suitable for all

Both men and women seek laser hair removal to get unwanted hair removed. Hair removal is commonly done on the hairline, eyebrow, top of the nose, side burn, upper & lower lip, chin, ear lobe, face, neck, nape, shoulders, back,, underarm, abdomen, buttocks, public area, bikini lines, thighs, breast, arms, legs, hands, and toes.

Lasting reduction

The US : FDA has approved the process as "Permanent Reduction" which means that one shouldn't expect laser to remove every single hair from an area. Some might need touch up treatments once or twice a year after the initial set of treatments for any new growth the body may develop.

Hair less but not careless

Following precautions are expected from a patient during the course of the entire treatment.

• No waxing or removing hair from the root by any other way.
• After treatment is completed, aloe vera should be applied to soothe the skin.
• Exfoliating and/or scrubbing gently in the shower with a loofa after the treatment may help speed up the shedding process of hair.

How long before I can flaunt my new look?

The number of treatments depends on the skin and hair colour, density and coarseness of the hair as well as the specific area to be treated. On an average , 5 - 7 treatments, scheduled 4 to 6 weeks apart will approximately reduce hair growth by 70 - 90 % .

Additional session might be required to eliminate the hair that come out of the dormant phase and become active later.

Will there be any side effects?

There are no lasting side effects of laser hair removal on a healthy body. However , one might experience the following immediately after the treatment:

• Normal itching during the treatment
• Temporary Redness
• Temporary Swelling
• Pain, Tingling or Feeling of Numbness

How about reducing the density of the hair and not completely removing them?

Yes, This can be achieved. Please contact our doctors who will help you with the process and consult accordingly.

About Hair:

Hair is a dermal appendage found almost everywhere on the human body except the palms, soles, and lips. Vellus hairs are fine, colorless hairs ("peachfuzz") covering most of the body, except those areas covered with Terminal hairs, which are coarse pigmented hairs found on the scalp and eyebrows. Vellus hairs can transform into terminal hairs when stimulated by androgens (male sex hormones), especially those on the face, back, chest, abdomen, axillae (armpits) and genitalia at puberty. Vellus hairs can tranform into terminal hairs with aging. The number of hair follicles present in the skin is fixed at birth.

The hair shaft is composed of the protein keratin and is produced in the lower part of the follicle, or bulb. The middle part of the follicle contains the opening for a sebaceous gland, the attachment of the arrector pilii muscle, and a thickened area in the root sheath called the "bulge", which is believed to contain stem cells important for regeneration of the hair follicle. Melanin is produced in the bulb and possibly in the bulge, and concentrated in the hair shaft and upper part of the bulb. Depending on the thickness of the skin, the bulb may be as deep as 7mm, below the skin in the subcutaneous tissue. Actively growing, or anagen hair follicles are longest and deepest, while follicles just coming out of dormancy, the bulb is much more superficial (see hair cycle, below)

Melanin is the pigment which gives both hair and skin its color. Much more melanin is present in hair than in skin, and this property allows relatively more absorption of laser light energy in hair than in skin (see below). Hair color is determined not only by the absolute amount of melanin, but by the relative amounts of black-brown eumelanin and reddish brown pheomelanin, and refraction of light within the layers of the hair shaft itself.

Hair growth cycle: Hair growth occurs in cycles throughout an individual's lifetime. Active hair growth is called Anagen, and the length of the anagen phase determines the length of the hair. Scalp hairs may remain in the anagen for up to 3 years. Hair follicles then enter Catagen, a phase of regression which lasts a few weeks. The Telogen, or resting phase, can last for months, depending inversely on the number of actively growing hairs in the area, ie. the scalp has a shorter telogen phase than the chest. As anagen resumes, the hair follicle lengthens, the bulb descends deeper into the skin, and the old hair shaft is gradually shed. In humans, individual hair follicles are more or less independent, with most hairs in anagen at any given time. In animals which shed their hair, the follicles cycle more or less simultaneously.

Physical Basis for Laser Hair Removal: Laser Hair Removal is based on the principle of selective photothermolysis, in which energy is delivered to the treatment area in such a manner as to maximize tissue damage to the hair follicle while sparing the skin and surrounding tissue. Melanin pigment makes a logical target chromophore, because it's most abundant in the hair bulb, which is believed to be the most important target for hair removal, much less abundant in epidermis, even in dark-skinned patients, and it absorbs well in the skin's "optical window" between 600-900nm.

Wavelengths under 600nm are strongly absorbed by hemoglobin and protein (scatter), and wavelengths above 900nm are strongly absorbed by water in tissue. Skin is relatively "transparent" in the 600-900nm range, with melanin-bearing structures as the most attractive target for laser energy.
Melanin absorption decreases with increasing wavelength. Ruby laser light at 694nm is strongly absorbed by melanin, not only in hair but in epidermis, so epidermal melanin content limits the depth of penetration and energy fluence that can be used without unacceptable thermal injury to the skin. Nd:YAG laser light at 1064nm is much less strongly absorbed by melanin as well as other chromophores present in skin, and therefore penetrates much more deeply and with minimal epidermal reaction and collateral heating. These properties can be exploited clinically, as outlined below.

Diode Laser: Solid state 800nm diode lasers feature a longer wavelength and pulsewidth, theoretically offering an advantage in treating darker skinned patients. The Aesculap-Meditec MeDioStar has obtained the USFDA approved for Permananent hair reduction.

Q-Switched Nd:YAG: With a wavelength of 1064nm, relatively low melanin absorption, and skin penetration up to 5mm, the Nd:YAG laser is an excellent choice for laser hair removal, at least in theory. However, the nanosecond-range pulse width of the Q-Switched YAG is thousands of times too short to cause complete disruption of the hair follicle, resulting in prompt hair regrowth. In order to enhance absorption of energy, a suspension of carbon particles can applied before treatment, usually after hair removal by waxing, allowing the carbon suspension to penetrate into the follicle and conduct absorbed laser energy to the follicular structures, as in theThermolase SoftLight system. Although safe for darker-skinned patients and effective for short term hair reduction, the Q-Switched Nd:YAG is generally considered the least effective laser for long-term hair reduction.

Photodynamic Therapy: In photodynamic therapy a photosensitizing compound is applied topically to hair-bearing skin after waxing, to allow the compound to enter the now-empty hair follicle. The area is then irradiated with laser light to activate the photosensitizer, which releases toxic oxygen radicals that damage the hair follicles. Currently in the investigational stage, preliminary studies have demonstrated up to 40% hair loss at 6 months after a single treatment. Photodynamic therapy has been used with limited success for certain malignant tumors, but the lack of safe, effective, selective photosensitizers have limited its use.

Practical Aspects of Laser Hair Removal:

Preoperative evaluation: The most important consideration with Laser Hair Removal is the patient's skin type and hair color. The differential absorption of melanin in the hair follicle and melanin in the epidermis determines the amount of energy that can be safely used. The Ideal Patient has light (type I) skin with black hair, and a patient with very dark (type VI) skin with white or grey hair would have little if any response. Presumably because of the absence of melanin, no currently available device works well in patients with canites, or grey hair.

An underlying cause for the excess hair, if present, should be corrected. These causes may include endocrine abnormalities and medication effect, including minoxidil, steroids, oral contraceptives, and some immunosuppressive agents.

Contraindications to Laser Hair Reduction include patients who have healed poorly after other types of laser treatments, patients prone to skin discoloration, patients with grey or white hair, and patients who are pregnant. There's no scientific evidence to suggest that laser light used in hair removal can injure a fetus, but the question of injury will not arise should any fetal problems occur. Patients who are tanned should wait for the tan to fade for best results, and patients using photosensitizing medication such as Accutane, tetracycline, or Retin-A should discontinue the medication weeks, and for Accutane, months before treatment. Herpes Simplex Labialis (fever blisters) can be activated by Laser Hair Removal, especially on the upper lip, and patients with a tendency for fever blistering can be started on antiviral medication before treatment.

Preoperative preparation: Hair should not be plucked or waxed before treatment. This removes the hair shaft from the follicle, thus removing most of the melanin chromophore. Hair may be shaved, which preserves the chromophore in the follicle, and prevent dispersion of energy by external hair. Lotions, cosmetics, and other skin preparations should be avoided on the day of treatment.

Postoperative care: In most cases, little specific postoperative care is necessary. Mild burning sensations and redness can be treated with ice packs and oral pain medication. In cases where blistering occurs, topical antibiotic cream and a non-adherent dressing can be applied. Sun exposure should be avoided, and an SPF 15 or greater sunblock should be used. Moisturizing lotions and makeup may be applied the next day. During the weeks after treatment, damaged hair follicles and hair shafts are extruded or shed, and may be misinterpreted as early regrowth of hair. This is especially noticeable in areas with thick, coarse hair.

Efficacy of Laser Hair Removal: The "permanence" of Laser Hair Removal is often called into question. In practice, no laser destroys all of the hair follicles. Some follicles are destroyed, others are miniaturized into vellus hairs, and some are shocked into prolonged dormancy. Multiple treatments are needed for best results, and the best interval for treatment is when new hair regrowth is observed, usually 6 to 12 weeks after the first treatment, and 3 to 6 months after the second treatment. In most cases there will be visible improvement within a week after the first treatment. Repeat treatments can be performed at suitable intervals.

It's possible that with a sufficient number of treatments, true "permanent hair removal" can be ultimately achieved, but not for every single hair present in a given area. As an example, only 30% of hair follicles on the back are in anagen (active growth) at a given time-70% of the hair follicles are in telogen (dormant), even though they may contain visible hairs. Assuming a single laser treatment permanently eliminates every actively growing follicle (the actual figure may be closer to half), 70% of the hair follicles originally present may eventually sprout visible hair. After 3 months (the average length of dormancy on the back), 30% of the remaing follicles will enter anagen, and if a second laser treatment eliminates every actively growing follicle (30% of the 70% remaining after the first treatment), then only an additional 21% of the original hair follicles will be destroyed, leaving 49% of the original hair follicles able to regrow visible hair. A third treatment will leave 34% of the orginal follicles, a fourth 24%, and so on. In actual practice, some of the follicles are shocked into prolonged dormancy, or converted to vellus hairs, so the visible effect is greater than suggested by the percentages. Experience to date with laser hair reduction suggests that the hair reduction achieved is "permanent".
