LOW-LEVEL LASER THERAPY FOR HAIR LOSS

LOW-LEVEL LASER THERAPY FOR HAIR LOSS

Low-level laser therapy (LLLT) known as “cold laser therapy” because the level of light is low which isn’t enough to heat your body’s tissue. LLLT is a form of light treatment for hair loss in men and women. This is a US FDA-approved therapy that uses clinical-strength laser technology, for genetic or hereditary; male and female pattern hair loss.

Low-level laser therapy (LLLT) is also known as Photobiomodulation (PBM Therapy), photobiostimulation, red light therapy; use of photons at a non-thermal irradiance to alter biological activity.

Low-level laser therapy (LLLT) uses either coherent light sources (lasers) or non-coherent light sources consisting of filtered lamps or light-emitting diodes (LED) or, on occasion, a combination of both and the wavelength used are 420,530,590,640,670,880.

Low-level laser therapy (LLLT) involves exposing cells or tissue to low levels of red and near-infrared (NIR) light and over injuries or lesions to improve wound and soft tissue healing, reduce inflammation and give relief for both acute and chronic pain.

The Low-level laser therapy (LLLT) irradiates diode rays, which penetrate the scalp to treat hair loss. LLLT for hair loss emits the wavelength of infrared light is 630-670 nanometres

The Low-level laser therapy (LLLT) treatment is non-invasive, safe, and pain-free light technology to stimulate the hair follicle. It’s a supportive evidence-based therapy to the supplementary or medicines such as minoxidil and finasteride. However, it is non-invasive to other interventional treatments (mesotherapy, PRP, or hair transplant) of hair loss.

There are different LLLT devices available in the market as:

  • Professional machines with overhead panels.
  • Home or Hand-held devices.
  • Head Caps.
  • Head helmet.
  • Comb or Brush

Low-level laser therapy (LLLT) used in a coherent light source such as 308 Excimer, targeted Phototherapy (Daavlin), helium-neon (632.8 nm), and fractional erbium-glass (1550 nm). This explains the extensive use of these devices in hair growth.

Low-level laser therapy (LLLT) is advised twice or thrice a week for a period of 3 to 9 months. Professionals therapy at a medical centre and handheld at home are administered respectively, for a period of 10 to 15 minutes the scalp is exposed to laser-emitting diodes.

Moreover, massage of the scalp along with therapy promotes blood circulation and enhances the effectiveness of Low-level laser therapy (LLLT).

Ideal patients with hair loss

Patients with hormonal and genetic influence (androgenetic alopecia) or pattern hair loss are ideal candidates for Low-level laser therapy (LLLT).

Hair professionals usually recommend for mild to medium degree of hair loss.

Type I to Type V Norwood-Hamilton Classification.

Woman with Type I & II Ludwig scale.

Mechanism of action

Low-level laser therapy uses photons at a non-thermal irradiance to alter the biological activity of scalp cells or tissues. The photons emitted by the low-level laser beams acts on:

1. Release of nitric oxide from the targeted scalp cells. Nitric oxide increases blood flow or vasculature of the scalp; which helps in the supply of oxygen and nutrients to the hair root or follicle. Hence, it reduces the peri-follicular inflammation responsible for the initiation of hair loss.

4.It acts on enzyme cytochrome C oxidase to produce adenosine triphosphate (ATP) which converts to cyclic AMP in the hair follicular cells. However, this releases energy and further stimulates metabolic processes necessary for the hair growth cycle.

3. DHT (dihydrotestosterone), is an androgen produced as a by-product of testosterone. In genetically susceptible to hair loss or pattern hair loss. Low-level laser therapy (LLLT) works by preventing the excess build-up of DHT by blocking a step ahead in the formation

4.Low-level laser therapy (LLLT) acts on the sebaceous glands, reducing the oiliness in the scalp and also helps in reducing dandruff and dryness. Low-level laser therapy (LLLT) is also having anti-inflammatory properties.

Advantages of LLLT:

  • It is a safe and pain-free procedure.
  • It is a non-invasive procedure. 
  • No side-effects.
  • It reduces hair fall and increases hair thickness and.
  • It has perceptible hair growth after 3 to 6 months of treatment.

Moreover, certain drugs such as photosensitizing agents can have interaction with Low-level laser therapy (LLLT), as these drugs increase sensitivity to light therapy.
