Laser light or red-light therapy is a drug-free treatment for addressing numerous conditions like hair loss. The red laser light helps in activating the natural defense mechanism of the body’s nutrient systems which initiates a rejuvenating, healing process.
This initiates a rejuvenating or healing process. Some people may feel uncertain about the idea of using a red laser light for stimulating hair growth on the scalp. But, the treatment has been refined and well-researched for over forty years now.
The medical benefits of the red-light therapy have been validated by the studies conducted by NASA. Many people find the power of red light astonishing. You can use red light therapy to alleviate joint pain, heal wounds, reverse sun damage and restore hair growth. The light emitted at the wavelengths between 630-670 nm aid in treating hair loss. You do not necessarily require a laser device for the treatment. Any device operating and emitting red light at the necessary wavelength will aid in hair growth.
The hair follicles absorb the red light, which stimulates hair growth. The hair follicles must absorb the light to initiate the natural biological reaction. An intracellular enzyme known as Cytochrome C present in the hair follicles absorbs the red light. The enzyme also stimulates the hair follicles to send signals to promote gene activity as well as reduce the death of cells regulated by the genes.
Your hair follicles require a number of nutrients to stay healthy. Laser therapy enhances the production of ATP (Adenosine triphosphate) and keratin. The molecules of these nutrients carry energy to the areas of the scalp wherever it is required. The correct cellular function requires energy to effectively synthesize membranes, proteins and for cellular division.
Oxygen starvation is a critical element responsible for the loss of hair and limited growth. Moreover, it retards cellular repair. A treatment with red light therapy helps in stimulating the scalp tissues by increasing the delivery of oxygen, the number of red corpuscles and nutrients to the hair bulb. The treatment also initiates a reaction at the cellular level by increasing cell division, micro-circulation, tissue regeneration and protein synthesis.
Dihydrotestosterone or DHT is locally produced by the hair follicles. It is a primary cause of male androgenic alopecia. A treatment with red light laser /LED helps in reducing DHT from the scalp which allows efficient delivery of nutrients. In cases of hair loss in females, the situation is more complex. Regardless, DHT is assumed to be one of the probable causes.
The mode of treatment may vary, depending on the specific cause of hair loss. Currently, no known therapy can effectively treat all forms of hair loss because no one-size-fits-all treatment is available for every ailment. For example, you may have hair loss as a reaction to a certain medication. You will continue losing your hair until you stop using that medication.
The earlier you start a treatment, the better chances you have of succeeding in the treatment. Once a hair follicle has died, you cannot do much to resurrect it, much like dead brain cells. Therefore, doctors suggest if you plan for a hair loss treatment, starting early can ensure optimal success.
Red light hair loss therapy and low-level laser therapy are ideal for people who temporarily lose their hair because of issues like medication side effects, physical or emotional stress or other physiological conditions, such as menopause.
You can see significant results in two to three months. Although hair cells generally divide and regenerate fast, the process does not show results overnight. Do not stress out. Let your body work at its own pace. You did not lose the hair overnight, they will not grow back overnight either.
