What is laser hair removal?

Laser Hair removal is the revolutionary long-term hair removal technology that uses laser technology to get rid of the unwanted hair in any part of the body.


What is hair anatomy?

Anatomy Hair follicles are composed of the bulb (matrix and dermal papilla), outer root sheath, bulge, and hair shaft. The hair matrix depth in the skin ranges from 2 to 7 mm, depending on the body location, and the hair bulge is approximately 1.5 mm. Hair growth occurs in three phases with distinct changes below the skin in the hair bulb: (1) anagen, the active growth phase during which the hair bulb is most darkly pigmented; (2) catagen, the regression phase when cell division ceases and the follicle begins to involute; and (3) telogen, the resting phase during which the hair bulb is minimally pigmented. Hair growth is initiated by epithelial stem cells located in the bulge, a protrusion near the attachment of the arrector pili muscle. During anagen, the rapidly dividing matrix cells of the hair bulb cause the hair to elongate and transfer melanin to the hair shaft giving it pigmentation. The hair shaft, visible above the skin surface looks unchanged during the three phases of hair growth. Two types of hairs are present in adults: vellus and terminal. Vellus hairs are fine (i.e., thin) usually with a diameter of 20– 50 μm and are lightly colored. Vellus hairs are often referred to as “peach fuzz.” Terminal hairs are coarse (i.e., thick) usually with a diameter of 150– 300 μm and are darkly colored. The type of hair produced by an individual follicle can change over time. For example, during puberty increased androgenic hormone levels cause vellus hair to be replaced with terminal hair in certain parts of the body. In androgenic alopecia, terminal hair can be replaced with vellus hair.


How does Laser hair removal work?

Selective photothermolysis is the cornerstone for the laser hair removal. Simply, the lasers are a series of a light photon within one wavelength. For the therapy to work, we need a material that can absorb the energy of lasers; this material is called chromophore. Melanin pigment gives hair and skin its color. Melanin is located in several areas of the hair follicle including the hair shaft, bulb, and outer root sheath. Two types of melanin pigment are synthesized by melanocytes: eumelanin and pheomelanin. Eumelanin is brown to black in color; it is the predominant type in dark Fitzpatrick skin types (IV– VI) and is found in darkly pigmented hair. Pheomelanin is yellow to red in color; it is the predominant type in light Fitzpatrick skin types (I– III) and is found in red and blonde hair. White and gray hairs have no melanin. like other chromophores, Melanin has a spectrum of absorption, it is like a straight declining line starting from 400 nm to 1200 nm. These are the main wavelength being used for laser hair removal ruby (694 nm), alexandrite (755 nm), a diode (810 nm), and Nd: YAG (1064 nm). Intense pulsed light (IPL) is not a laser as it has emission spectrum. Once the melanin is in contact with the laser beam, it will absorb the energy and turns it into heat. The heat will disrupt the hair normal cellular growth leading to hair removal.

Why does it take multiple session for Medical laser hair removal?

Medical Laser hair removal is most effective when a hair follicle is at a specific growth stage (anagen). Usually, hair follicles are at three different growth stages. It might take a hair follicle couple of weeks or month to go through the whole growth stages, depending on the body part. We need to hit the hair with the laser beam at that the anagen stage. One session will terminate most of the hair at that stage; then we have to wait for the hair that survives the first session to growth to that stage before we hit it with laser again. There is no way for us to know what stage a hair follicle is at. By adjusting the setting and spot size, we can target as much hair as we could.

    Laser hair removal is a medical procedure that uses a laser — an intense, pulsating beam of light — to remove unwanted hair. During laser hair removal, a laser beam passes through the skin to an individual hair follicle.
