One of the unique features of mammals is their ability to grow and regenerate hair. Hair follicles typically undergo repetitive regenerative cycles. Each cycle consists of three stages of hair growth:
Hair loss and hair thinning happen when this hair growth cycle is disrupted. Hair loss is a common condition that affects most people the world over. The most common cause for hair loss is androgenetic alopecia. It commonly affects males over the age of 40 and females over the age of 65. However, there are other causes for hair loss as well:
In 1967, Hungarian researcher Mester found that 500 mili watts, low power 694 nm ruby laser increased hair growth on backs of shaved mice. Later, controlled clinical trials showed that Low Level Laser therapy (LLLT) stimulated hair growth in both men and women. LLLT works by enhancing the oxygen exchange chain in the mitochondria, leading to more ATP and Cyclic AMP formation. The displacement of nitric oxide & toxins out of the cells allows more oxygen to enter them. This stimulates better growth, induces angiogenesis, forming new blood vessels around the hair follicles, reduces inflammation and activates response to reactive oxygen species.
LL laser therapy for hair loss works equally well for both men and women.
The red light wavelength of the spectrum from a laser that emits 650—670 nm light can stimulate cells within the follicle, encouraging hair growth.
The energy of the low level lasers is delivered directly to the scalp. It promotes cellular metaboloism by increasing blood circulation and oxygen to the hair follicles. This in turn stimulates hair in the resting phase (telogen) to the growth phase (anagen).
LLLT works for anybody who has just started to notice hair loss to anyone who is suffering from a hair loss.
It is ideal to have LLLT for hair growth twice a week. For busy patients, even once a week is effective for hair growth stimulation.
You need to wear the special helmet provided by the therapist for 20 minutes. The device at Pandit Clinic has an auto shut off after 20-25 minutes.
As per the new classification developed by US FDA for this Laser, it is LLLT – Low Light Laser Therapy. The strength is just ½ Watts, so is very safe to use.
