Low-Level Laser Therapy – For Hair Loss
Low-Level Laser Therapy is a fast growing technology, especially in the fields of physical medicine and rehabilitation. As the matter of fact that skin is naturally exposed to light, it responds well to red and near-infrared wavelengths. These two laser lights are well-known to promote the tissue repair and regeneration by efficiently stimulating the cellular activity. LLLT has shown positive effects for multiple medical conditions, such as nerve regeneration, stroke recovery and is specifically a helpful treatment for different kinds of hair loss.
LLLT & Alopecia:
Androgenetic alopecia is the most common type of hair loss that affects 70% of the men and 40% of the women at some point in their lives. It is also called pattern balding. Finasteride and Minoxidil are FDA approved drugs. Low Level Laser Therapy has been highly recommended for hair loss other than hair transplant.
Studies have shown that LLLT successfully stimulates hair growth along with decreasing the inflammation and increasing the local blood flow. It is FDA approved, which means it is both safe and effective.
Mechanism of Action:
Hair growth includes three phases, which are:
Anagen Phase – the growth phase,
Catagen Phase – the transition phase in which the hair follicles start shrinking,
Telogen Phase – the phase in which hair follicles eventually shed.
LLLT works by shifting the hair follicles into the anagen phase via different helpful methods so to restore the hair growth. The process begins when a light penetration of predetermined wavelength (in the range of 630 to 670 nanometers) that works by entering into the scalp and getting absorbed by the molecules of hair follicles. In this way, the epidermal stem cells are stimulated that take the responsibility of regenerating the follicles. The technology causes the increased blood flow in order to increase the process of oxygen and nutrients delivery to the follicles. As the ending process, the metabolic processes that are essential for hair growth are stimulated in order to prevent the build-up of the DHT.
What LLLT Can & Can’t Do:
Basically, LLLT is best suitable for treating the hair that are weak and thin, as it works by making them thicker and stronger along with turning the wispier follicles into healthier ones. Moreover, it is also very helpful in stopping the hair loss process mid-way. However, it doesn’t work when the hair follicles are not active as it only causes hair growth in alive follicles. Therefore, it is best suggested that you start the process as earlier as possible so enjoy the maximum benefits.
This is an easy process; each treatment takes 15 to 30 minutes and the recommended treatments per week are almost 2-3.
