Low-level light therapy (LLLT) or photobiomodulation or photobiostimulation is a relatively new technique used to promote hair growth in both men and women with AGA and female pattern hair loss. Low-Level Laser Therapy utilizes cool lasers to stimulate hair growth and reduce hair loss. Low level laser therapy (LLLT) uses devices with diodes that emit red light (wavelength 630-670 nanometers), or infrared radiation.Whereas the exact mechanisms of hair growth stimulation by LLLT remain unknown, LLLT has been proposed to accelerate mitosis and may stimulate hair follicle stem cells and reversing miniaturization (the process leading to thicker hair shafts and a fuller look)
There have been a number of commercially available devices as: 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.
Who are the best candidates for low level laser therapy for hair loss?
Low level laser therapy is intended for men and women with thinning hair or pattern baldness caused by a hereditary condition.
Benefits of laser therapy for hair loss
- Low level laser thereapy can be used in both men and women
- No adverse effects have been reported
- It is clean and painless
- Low level laser hair therapy is relatively inexpensive
- It requires minimal time commitment
- Some low level laser therapy devices are portable
- Hair growth may occur on the top of the head/crown and along the hairline of forehead
Can laser hair loss therapy be used together with other medication?
Yes, Minoxidil and Finasteride can be used together with laser; there’s no need of stopping the medication.
This treatment method is safe but should not be used concomitantly with medications or products that are photosensitising.
