A relatively new addition to the tools that some trichologists use to combat hair loss is laser treatment. We have compiled some facts below about this effective method:
Low Level Laser Light Therapy as a Medical Treatment
Low-level laser light therapy (LLLLT) is a form of physical medicine. Physical medicine uses stimulation therapy to activate the body's natural defense mechanisms, i.e. through biostimulation.
What is Laser "Radiation"?
The name LASER is short for Light Amplification by Stimulated Emission of Radiation. Laser light and devices are sometimes referred to as laser emitting, laser producing, laser radiation, etc. This terminology is confusing. There is NO radiation in the sense we normally refer to as radiation. Lasers produce light high in energy, nothing else (even sunlight is a type of radiation). No radioactivity or dangerous energy is produced. Radiation with laser does imply that your head will get fried! The laser light is used as a 'cold light'.
Is Laser Hair Care Safe?
The type of lasers used by trichologists are non-surgical therapeutic lasers. Some trichologists use the most powerful laser that is safe for cosmetic purposes (and which complies with international laser safety standards). Laser Hair Care is approved for cosmetic use in the EEC and US as a Certified Class 3A laser by the Food and Drug Administration, which has the most rigid standards in the world and fully complies with Radiation Control for Health and Safety act. The energy produced by the photons does not have the thermal component that can cause injuries to users or operators. Laser light energy does not alter molecular structures, it stimulates the body's mechanism to repair and heal itself.
Benefits of Laser Therapy
- Increases scalp blood flow and follicle microcirculation by 20 to30%.
- Increases nutrient supply to enhance hair growth.
- Stimulates and accelerates hair growth.
- Reduces excess levels of skin 5-alpha reductase and dihydrotestosterone (DHT), the hormones that contribute to genetic thinning.
- Relieves scalp conditions such as psoriasis, seborrhoeic dermatitis, itchy/scaling scalp due to the laser's anti-inflammatory effects.
- Normalises sebum production in the scalp.
- Increases sebum production in cases of underactivity/scalp dryness.
- Reduces excessive sebum production in cases of overactivity/scalp greasiness, thus reducing pore clogging and preventing enlarged sebaceous gland formation.
- Reduces tight, tender scalp.
- An effective adjunct therapy for pre and post hair transplantation procedures.
