Laser Hair Regrowth Therapy: What Does It Really Do?

Laser hair restoration therapy is the exact reverse of the laser hair removal technique. This is because both procedures use different types of lasers. High level lasers that can deliver up to a thousand watts are used for removing hairs whereas low level lasers can only render up to an average of a hundred milliwatts which is why they are used to restore hair.

Low level laser therapy for hair restoration is a work-in-progress in the hair loss industry. It is a non-surgical and non-drug option for less serious cases of pattern baldness or androgenetic alopecia. Low level lasers are cold lasers which has been observed to bring several positive benefits to the cells. It works on the principle of photobiostimulation, a natural process wherein light energy is converted into chemical energy to improve cellular performance.

Certain ranges of wavelengths are essential in order for laser therapy to be effective.  A 670-nanometer laser is considered to be more effective than other wavelengths used for hair growth stimulation. Wavelengths that exceed at least 800 nanometers pose different biological effects as they can better increase mitochondrial ATP production. Yet still, because the scalp skin is thin, there will be no need for such wavelength. They will neither be beneficial nor destructive to the target tissues.

When the chromophores in the tissues  receive light, the energy is converted into chemical energy for more active levels of cellular performance and interaction. When the cells are revitalized, blood circulation improves simultaneously. Increased blood supply means increased supply of nutrition to the hair follicles. With reenergized hair follicles, there is a possibility for hair regrowth.

LLLT for hair regrowth has been effective in so many cases. Traditionally, only big hair clinics render it.  Laser combs which are medical devices, on the other hand, is laser therapy conducted at home.

Laser therapy is not a cure for hair loss. It only addresses the symptoms. Therefore, when the therapy stops, the effects will wear off.

Unlike other conventional treatments, LLLT is safe for the general public. LLLs are generally safe types of light sources. They don’t contain thermal, sonic, or vibratory components. In fact, they meet all international standards for a non-significant risk laser.Thus far, there has been no documented side effects from its application.
