laser hair regrowth device now has fda clearance
No cancer was found, but to his surprise, in the test area where the mouse was shaved, the hair grew much faster than in the untreated group.This effect, known as low level laser therapy (LLLT), is also known as laser biostimulation, light biological regulation, and cold laser therapy, and is now used to treat hair regeneration.Probably because of the high cost of laser technology at the time, few studies were conducted in the 20 years after the first experiment.
During the 1980 s LLLT, it began to become an expensive treatment through a number of specialized hair clinics.The laser used is a large complex fixture and the patient has to sit under the hood similar to the salon hair dryer.The frequency of treatment is 2-3 times a week, this is usually inconvenient for those who may have to travel many miles to the nearest clinic or salon.
However, the results achieved were very good and soon many salons across Europe, Asia and the United States began to offer treatment.This laser hair regeneration treatment has now been supported by many scientific studies for effective hair loss treatment.1982 at M. TrellesAnd Mayayo, E, published the HE-NE Beam”.
In this study, patients with alopecia areata responded positively after treatment 6 to 8 times a week.The study in the 1990s S tested the laser working at different wavelengths and pulse-treated the laser to find the most effective laser configuration for the treatment of hair loss.At present, the working wavelength of most therapeutic lasers is 600-1000nm, where the wavelength is related to the distance of light penetrating the scalp.
The best wavelength to use is still controversial, but at least penetrate 5-Depth of 6mm, with the goal of hair bulb.Many current LLLT devices work with a visible red light with a wavelength of 660nm, which can penetrate to about 8-10mm.Higher wavelength laser of 800-These can penetrate to a depth of about 30.
40mm but these are mainly used to treat joint and muscle-related problems.Recent LLLT laser hair regeneration studies have begun to shed light on the causes and ways laser therapy can help stimulate hair regeneration.These studies have shown that the laser increases the level of a chemical compound called the three-phosphate gland (ATP), which is thought to stimulate living cells, including hair follicles.
LLLT also has the effect of increasing blood circulation to hair roots that deliver nutrients to cells that make up follicles.An increase in blood flow is also considered to help flush out hazardous waste that may affect the hair growth cycle.This helps to improve the scalp environment, helps to stop hair thinning and promote new hair growth.
Over the past few years, laser technology has evolved to a stage where laser devices can now be manufactured in smaller sizes and at a very low cost than your little nails.In 2000, a company developed and patented the first micro LLLT laser hair regeneration device using a new laser technology.This first time makes it possible to have an effective LLLT hair loss treatment that is cheap and small and can be used in your own home without having to go to an expensive hair clinic.
The new device is in the form of a comb/brush, only 10-15 minutes 3 times a week.Manufacturers claim that while the user experience will vary, 45% of users will see positive results after 8 weeks of treatment and another 45% will see 10-16 weeks laterFebruary 2007, United StatesS.The Food and Drug Administration (FDA) approved a laser comb device for the treatment of hair regeneration.
The laser comb is now one of the three FDA-approved treatments for hair regeneration, with the other being finasteride and Minoxidil.Laser hair regeneration devices now bring new hope to many men and women with premature hair loss
