One of the most challenging and stressful situations for most people is the thinning and loss of hair. No one appreciates brushing their hair only to realize that the comb sweeps up bald spots on the head. Some leading causes of thinning or lack of hair growth include genetics, hormonal changes, or different medical conditions.

Even though some people feel comfortable being bald, not all people would look good or even fit the look. Hair growth is and will remain a sentimental topic to many people.

A rising popularity in the use of the red light therapy for the restoration of healthy hair is an approach that helps to pose the question whether the approach is functional and recommended or damaging and harmful to hair growth.

The wavelengths expose hair follicles either through handheld devices, tanning beds, or proper positioning of the rays above the head. The therapy recommends and explains that the red light does not damage or burn the skin. Instead, the skin absorbs the light by up to at least 10 mm, effective for stimulating the growth of hair.

The red light stimulates the mitochondria found in skin that, in turns, helps with the regeneration, repairing, and functionality of hair cells. The stem cells found in hair also go through an activation by the therapy that eventually promotes healing and repairing of any damaged hair cells.

A lot of controversy residing on the relevance of the red light therapy for the growth of hair originates from the poor comprehension of the approach. The result inevitably lead to controversial remarks on the efficiency of the therapeutic approach.

The Safety of the Red Light Therapy for Hair Growth

Despite all controversy surrounding the use of the red light therapy for hair growth, the approach proves to represent one of the safest and best initiatives for growing and re-growing hair.

Red light therapy, on the other hand, is less expensive compared to conventional approaches and also harmless because it involves no surgical approaches.

NASA?s research and analysis on the effectiveness of the use of the red light therapy proves the value of the approach in promoting hair growth. The experiment performed using plants by NASA provided valid results that offered a chance to test the therapy on people. The therapeutic approach gave positive results for the promotion of hair growth while exposing the human skin to no harm.

The therapeutic approach helps to promote blood flow through the hair follicles that, in turn, promote metabolism. Hair follicles then experience an increase through the catogen and telogen phases that helps to promote the anagen dedicated to hair growth. Therefore, increased use of the red light therapy helps to revert the phases of hair loss by promoting hair growth through the first stage, the anagen phase, responsible for hair growth.

The device focused on reducing hair loss among men using a wavelength of about 635 nm. Later in 2009, the FDA also approved other therapeutic devices focused on both men and women to promote hair growth.
