How does laser work for hair growth?
Laser therapy is becoming more and more popular in modern society, especially when it comes to hair loss. This new, exciting, and dynamic technology seems to have an exceptionally positive effect on hair growth. If you, like many others, have heard that it can truly help regrow your hair or stop hair loss, yet are wondering if this is too good to be true, read on to find out how the power of light really can change your confidence and your hair for the better.
The science behind laser hair therapy
It is essentially a light that stimulates follicles/cells to regrow hair. Mostly Low Level Light Therapy (LLLT) is used to address hair loss and thinning, this does not induce any heating such as that in tissue like surgical or aesthetic lasers. LLLT has a photochemical effect (like photosynthesis in plants). The effect depends on the application of the correct wavelength and density of light that is delivered to the target tissues for a suitable period of time. Usually this will be for a round 30-60 seconds, however this can vary from device to device.
The photochemical reactions of certain wavelengths of light combine with our cell membranes and enzymes. Compromised cells react better than healthy cells to photochemical reactions enabling brief treatments with low level light on damaged tissue or hair follicles to start a complex chain of physiological reactions.
How was it discovered?
In 1967, a Hungarian scientist was studying the use of laser for other purposes on mice. The mice were shaved in the area where they were supposed to receive treatment. What he discovered was that the mouse who received laser treatment hair grew back in the shaved area a lot faster compared to the other mice who did not receive the laser treatment.
How it is applied on to the scalp
Laser hair therapy is available in clinics with specialists applying it to your head; however, this can be expensive as well as inconvenient with having to travel there for multiple treatments of the course of a few months, or even years. To keep with the fast pace of modern life, laser hair therapy is becoming more and more popular to use at home. Whether it is through comb like devices, which you move over your head to tackle problems areas. Or the revolutionary Theradome Laser Helmet, which applies the laser light to a large area of your scalp. This cordless nature of this particular product makes is bliss to use and perfect for female hair loss since it covers the entire scalp with light to tackle all problems areas at once.
Laser hair therapy is not a one-time ‘fix’ for hair loss. It generally must be repeated at intervals to maintain results. Some take 3 to 4 sessions per week for 20 to 25 minutes, however this differs from device to device. It is suggested that results usually take approximately 4 to 6 months. Once hair growth is achieved, an on-going ‘maintenance’ schedule of reduced number of sessions per week is strongly recommended. This will help to maintain new growth and sustain healthier, fuller and more vibrant looking hair.
How we lose our hair
We lose hair as a result of many different reasons. Before starting to use laser hair therapy, it is essential to know the reasons why you are losing hair in the first place. If it is to do with taking certain medicines, this may mean that the laser therapy won’t work or be as effective. If you are losing your hair due to androgenic alopecia then such laser therapy is the perfect solution, in many cases for both males and females. This is because this type of hair loss usually occurs when the hair follicles don’t receive enough nutrients to produce full, healthy hairs due to too much DHT production. By using laser therapy helps to stimulate hair follicles. This stimulation helps to prevent the slow miniaturization of hairs; rejuvenating them in order to promote new healthy growth.
