Complications of Laser Therapy for hair removal

The use of lasers to remove hair has become very popular and has been vigorous promoted by the laser companies. It has been promoted as the ultimate in the hair removal centers or saloons. These laser machines are majority of times handled by the untrained personnel who have no or little knowledge about the mechanism of action of laser. They fail to tell their prospective clients about the complications of laser use.

The four major complications of lasers are laser burns and its sequellae, leukotrichia, paradoxical hypertrichosis and folliculitis. The other adverse effects reported after laser-assisted hair removal include erythema and perifollicular edema, which are common, and crusting and vesiculation of treatment site, hypopigmentation and hyperpigmentation (depending on skin color and other factors). Most complications are generally temporary. The occurrence of hypopigmentation after laser irradiation is thought to be related to the suppression of melanogenesis in the epidermis (which is reversible), rather than the destruction of melanocytes. Methods to reduce the incidence of adverse effects include lightening of the skin and sun avoidance prior to laser treatment, cooling of the skin during treatment, and sun avoidance and protection after treatment.

Majority of the laser hair reductions are done by technicians unsupervised by the physicians, that is the reason for majority of the laser hair reduction complications6 (Ref:complications of non-physician supervised laser hair removal; Canadian Family Physician:Vol 55: january • janvier 2009)

 

Paradoxical hypertrichosis after laser epilation (Paradoxical hair growth after laser hair reduction)

The laser sometimes can have strange phenomena over the unwanted hairs. In some persons, instead of removing hair, laser treatments can actually promote hair growth. This phenomena, known as hypertrichosisis (increased hair growth), and is paradoxical effect of laser hair removal (epilation). The new hair growth is actually created in part by the effect of the laser although this effect and how it occurs is not yet completely understood. It is believed that all laser and light sources have the potential to cause hair induction, especially in individuals with darker skin types (III-VI); with dark, thick hair; and with underlying hormonal conditions. Possible causes include the effect of inflammatory mediators and subtherapeutic thermal injury causing induction of the hair cycle. Treatment for paradoxical hypertrichosis is laser therapy of the affected area. The mechanism of hypertrichosis (increased hair production) is similar to the effect of Low level laser therapy effect, which acts at the cellular level and is based on the absorption of monochromatic radiation by components of the cellular respiratory chain in mitochondria. It increases adenosine triphosphate production and cell division in matrix of hair.

Paradoxical hypertrichosis (increase in hair growth) has a low incidence, ranging from 0.6% to 10%, and most commonly occurs on the face and neck. All laser and light sources have the potential to cause hair induction, especially in individuals with darker skin types (III-VI); with dark, thick hair; and with underlying hormonal conditions. Possible causes include the effect of inflammatory mediators and subtherapeutic thermal injury causing induction of the hair cycle.

Laser therapy for hair removal if does not destroy the hair follicles, it stuns its growth or just resets the hair growth.The hair growth of the follicles is synchronized and the end result is instead of hair removal there is increased hair growth. Though some of the thick hairs which have absorbed energy and have undergone complete photothermolysis do not grow back, but the rest of hairs which have received sub-optimal energy will grow back even thicker. The regrowth after laser hair reduction now becomes resistant to the laser treatment and cannot be now removed with lasers rather it will increase the growth of the hairs with lasers.

The hair growth after laser treatment is now wavy, fine, thin and irregular and becomes more and more difficult to be removed even by electrolysis.
