What is laser hair removal?
Laser hair removal in Rochester is a medical procedure (administered by a medical professional) that uses a concentrated beam of light, called a laser, to remove unwanted hair from various parts of the body. During laser hair removal, a laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or can delay future hair growth (Mayo Clinic).
Getting The Best Results
Hair color and skin type influence the overall success of laser hair removal. The typical reaction for the laser is to target the pigment of the hair (the hair follicle then absorbs the light and stops growing) and not the pigment of the skin. Because of this, the laser avoids damaging the skin. Therefore, for a lot of patients, the contrast between hair and skin color — dark hair and light skin — results in the best outcomes (free of damaging the skin). The risk of damage to the skin can be greater when there is little to no contrast between hair and skin color. Though advances in laser technology have made laser hair removal has made it a more viable option for people who have darker skin. For people who have gray, red, blond and white hair color the laser can also be less effective, as these hair colors don’t absorb light well (light is the basis for the success of laser hair removal). Note that laser treatment options for light-colored hair continue to be developed (Mayo Clinic).
Anatomy Of A Hair Follicle
The papilla is a large structure at the base of the hair follicle. The papilla is made up mainly of connective tissue and a capillary loop. Around the papilla is the hair matrix.
A root sheath is composed of an external and internal root sheath. The external root sheath appears empty with cuboid cells when stained with H&E stain. The internal root sheath is composed of three layers, Henle’s layer, Huxley’s layer, and an internal cuticle that is continuous with the outermost layer of the hair fiber. The bulge is located in the outer root sheath at the insertion point of the arrector pili muscle. It houses several types of stem cells, which supply the entire hair follicle with new cells, and take part in healing the epidermis after a wound. Stem cells express the marker LGR5+ in vivo.
Attached to the follicle is a tiny bundle of muscle fiber called the arrector pili. This muscle is responsible for causing the follicle to become more perpendicular to the surface of the skin, and causing the follicle to protrude slightly above the surrounding skin (piloerection) and a pore encased with skin oil. This process results in goose bumps (or goose flesh) (Wikipedia).

Hair Growth Process
Hair grows in cycles of various phases: anagen is the growth phase; catagen is the involuting or regressing phase; and telogen, the resting phase. Each phase has several morphologically and histologically distinguishable sub-phases. Prior to the start of cycling is a phase of follicular morphogenesis (formation of the follicle). There is also a shedding phase, or exogen, that is independent of anagen and telogen in which one or several hairs that might arise from a single follicle exits. Normally up to 90% of the hair follicles are in anagen phase, while 10–14% are in telogen and 1–2% in catagen. The cycle’s length varies on different parts of the body. For eyebrows, the cycle is completed in around 4 months, while it takes the scalp 3–4 years to finish; this is the reason eyebrow hair have a much shorter length limit compared to hair on the head (Wikipedia)
The procedure of each treatment?
Before any of the treatments are administered it is helpful to communicate with your medical professional about any concerns and underlying skin disorders, in order for them to treat you properly. Before each treatment a medical professional will numb the specific area of hair removal, this usually takes 30-60 minutes to take effect (AAD). Once the area is numb a medical professional will apply the laser to the specific area, vaporizing the hair resulting in small plumes of smoke that have a sulfur-like smell. HOw many treatments and how long each treatment will take will depend on the size of the treatment area (e.g.smaller areas will take less time). It is important to avoid, sunlight, tanning beds, avoid other hair removal methods, avoiding blood-thinning medications and shaving treatment area after laser hair removal treatments. The color and thickness of your hair, area treated, type of laser used, and color of your skin all affect the results. You can expect a 10% to 25% reduction in hair after the first treatment.
Are there side effects or risks of laser hair removal?
Most patients experience mild swelling and redness. Patients will see some loss of hair soon after the first treatment.
Based primarily on cohort studies, PH occurs in 3% of patients undergoing hair removal with lasers or intense pulsed light, yet rarely outside the facial/neck areas. Treatment modality does not seem to be a contributing factor. Continuation of treatment in areas with PH may be the most appropriate treatment (Springer 2021).
For hair removal or to reduce hair growth in unwanted places of the human body, laser have been used., there are different kinds of lasers available, but the selection of an ideal laser for ethnic skin has its limitations. It is very important to pick the right laser for the right type of skin. It is necessary to determine the skin type of the flounce, the pulse length and the laser type to be used before beginning the laser Therapy (University of Salahuddin).
Objective clinical assessment of hair reduction using the physician GAIS score in 90 anatomical sites scores an excellent reduction in 95.5% areas and good reduction in 80% areas. This current study shows that a synergistic combination of three diode laser wavelengths used for hair removal (755, 810, 1064 nm) is effective and safe to use in subjects skin types IV and V for facial and body hair (Wiley Online Library)
