However, application of low level laser therapy (LLLT) to the scalp!!

Alopecia or hair loss is a common issue affecting more than half of the population worldwide. Androgenetic alopecia (Hair loss) can affect up to 70% of men (male pattern balding) and 40% of women (female pattern balding) at some stages of their life.

While men typically present with a distinctive hair loss pattern involving hairline recession and vertex balding, women normally exhibit a diffuse hair thinning over the top of their scalps. For both men and women, losing their hair is a always disappointing.

Only two approved drugs have been in use so far – minoxidil and finasteride, with minimal results. Hai transplant surgery is the other treatment alternative. However, application of low level laser therapy (LLLT) to the scalp, also is proved and safe alternative or an additional treatment for hair loss.

How Does Low-Level Laser help Hair Regrowth ?

Laser hair therapy uses medical-grade lasers to deliver safe, low level laser light to your scalp. Like the water and nutrients are absorbed by plants, LASER light energy is absorbed by your hair follicles so that your hair can continue to grow. As the light is absorbed, microcirculation increases, thereby distributing more abundant blood supply and nutrients to the hair follicle. Low level laser light stimulates cellular activity in your follicles to help diminish hair loss while helping regrow hair.

The hair growth cycle consists of three phases: growth (anagen phase), resting (telogen phase) and shedding (catagen phase). Hair loss in androgenetic alopecia depends on a testosterone derivative in the skin, dihydrotestosterone (DHT). Low level laser therapy is believed to increase blood flow in the scalp and stimulate metabolism in catagen or telogen follicles, resulting in the production of anagen hair.

Who are the best candidates for low level laser therapy for hair regrowth ?

Low level laser therapy is intended for men and women with thinning hair or pattern baldness caused by a hereditary condition. Physicians use a system known as the Norwood-Hamilton Classification (men) and the Ludwig-Savin Scale (women) to describe the degree of hair loss. Low level laser therapy is intended for promotion of hair growth in males who have Norwood Hamilton Classifications of IIa to V, in females who have Ludwig (Savin) I-4, II-1, II-2 classification of hair loss pattern and Receding hairlines.

How is low level laser hair therapy administered ?

Laser hair therapy may be delivered in a salon by professionals trained in its administration, or at home. Two to three times week.

In general, laser hair therapy is meant for men and women with all lengths of hair that are noticing thinning. This would potentially mean they are in the early stages of hair loss.

  • in-salon hoods or overhead panels
  • bonnet or head caps
  • hand-held devices.

Two to three times weekly treatments are typically recommended, and consist of a 8 to 15-minute exposure of the scalp to light-emitting diodes under a bonnet or head cap or using a handheld comb or brush. Scalp treatment and massages that promote blood circulation may be done additionally as part of the treatment.
