Laser Hair Removal and other commonly used methods

Laser hair removal is one strategy of therapy for undesirable body hair.

Body hair may perhaps be undesirable for patients for cultural, social, cosmetic, or psychological reasons; unwanted hair can result in feelings of embarrassment or emotional burden that may perhaps impede patients’ relationships or everyday activities.

This level of impairment is comparable to that skilled by patients with psoriasis and eczema and eclipses that skilled by patients with acne.

Adequate techniques for hair removal have long been in demand; long-term hair removal with minimal adverse effects will be the ultimate goal. Laser hair removal has turn out to be nicely established as an productive type of treatment for unwanted body hair.

The shaving and hair removal market in the United States increased 8% in between 2002 and 2007 and is currently 1.8 billion dollars annually.None of the hair removal approaches practiced at this time gives total or permanent hair removal. This aim will likely be reached with a far more complete understanding of anatomy, physiology, hair growth cycles, and laser-tissue interactions, and as extra sophisticated technologies emerge.

Various procedures are successful in temporarily removing hair:

Removing hair by Waxing
Application of a warmed wax or a sugary paste to areas of hair-bearing skin after which removing it, together with the unwanted hair, is usually a well-liked approach of hair removal and is typically performed at salons and spas.

This method may possibly be used over large skin surface areas (eg, legs, arms, back) or tiny controlled areas (eg, face, eyebrow, bikini location). New hair growth appears additional slowly than with shaving, as the hair should grow towards the level of the skin surface just before it appears.

Stripping of the wax or sugar paste from the skin is generally unpleasant or painful and may trigger adverse effects which include irritant dermatitis, accurate or pseudofolliculitis, hyperpigmentation, scarring, and thermal burns from hot wax or poor method.

Manual plucking
This method is an easy and practical technique to remove single hairs and could be utilized by most individuals for clearing smaller numbers of unwanted hairs. The hair shaft have to be long sufficient to be grasped by tweezers.

Plucking generally induces a hair follicle into its active growth phase, or anagen, thus stimulating new hair growth. In addition, it can create postinflammatory hyperpigmentation, true or pseudofolliculitis, and, very rarely, scarring.

Shaving
Despite the fact that quick and successful for clearing a substantial surface region of hair, shaving will be the most temporary technique of hair removal, as it only cuts the hair in the skin surface. As the hair continues to grow, the blunt finish of the cut hair is a lot more noticeable mainly because it truly is thicker than a typical tapered finish.

Disadvantages consist of skin lacerations, possible pyoderma, folliculitis, ingrown hairs, and postinflammatory hyperpigmentation. Several girls may well not use this approach on specific places of the body because of masculine connotations of shaving the face and neck.

Depilatory preparations
Preparations containing thioglycolates or strontium sulfide are probably the most widely applied chemical depilatories. These agents disrupt the disulfide bonds (specially cysteine) that hold hair cells together, thus dissolving the hair. Like shaving, this approach offers only a brief hair-free period, as hair continues to grow from the level of the skin surface.

The significant adverse effect will be the potential for irritant or allergic get in touch with dermatitis, which may perhaps cause substantial itching or rash.

Chemical bleaching
Bleaching with hydrogen peroxide is an effective technique of disguising the presence of hair but doesn’t really get rid of hair.
This is especially effective for people with fine but dark and, consequently, noticeable hair on the arms, face, or neck.

Electrolytic therapy
Successful electrolysis can achieve permanent hair follicle destruction to some degree in 15-80% of patients. It employs a weak direct current that passes via a negative electrode (anode) inserted in the hair follicle plus a positive electrode (cathode) inside the type of a wet pad inside the patient’s hand. Follicular destruction is achieved via the formation of toxic sodium hydroxide

Electrothermolysis utilizes an alternating existing that causes direct thermal destruction of the hair follicle.

Each and every hair must be treated individually plus the method is slow and may perhaps be painful. Adverse effects consist of discomfort, scarring and hypo- or hyperpigmentation.

Medicated treatment with eflornithine
Available by prescription only, eflornithine 13.9% cream was approved for topical use by the Food and Drug Administration (FDA) on July 31, 2000. Topical eflornithine might irreversibly inhibit skin ornithine decarboxylase activity, resulting in a reduction inside the rate of hair growth.[1] The onset of action may well take 4-8 weeks of using the topical cream for undesirable facial hair on the mustache and chin area.
One of the most frequent adverse effects of topical eflornithine cream consist of, but are not limited to, acne, pseudofolliculitis barbae, skin irritation, and rash.

Laser hair removal

Because 1996, when photoepilation-using laser technology 1st became readily available for use, many advances have occurred in laser hair removal, resulting in distinct sorts of lasers now readily available for therapy of excessive hair. Laser hair removal is based on the theory of selective photothermolysis, or selective destruction of the follicular unit, resulting in substantial hair reduction in treated areas.

Adverse effects are primarily related to epidermal harm by partial absorption of laser energy by the surrounding skin. This impact has been far more pronounced in darker-skinned individuals whose increased skin melanin concentration places them at a greater risk of adverse effects. These adverse effects consist of blistering, hypo- or hyperpigmentation (see image below), scabbing, or, incredibly rarely, permanent scarring.
