People lose around 100 hair strands, every day. While many of them experience normal hair regrowth, some people are unable to grow new hair. Some of the many reasons that can cause hair loss and baldness include:
The various treatments that can help with hair loss include medicines like minoxidil, hair transplant surgery, and low-level laser therapy for hair loss. In this guide we will look at LLT for hair loss in detail and how it can help stimulate hair growth.
How does low-level laser therapy work?
Low level laser therapy for hair loss
Low light laser therapy for hair is also known as red light therapy and cold laser therapy. This procedure includes photon radiation that penetrates the scalp tissues. These photons help strengthen weak cells and encourage healthy hair growth. The procedure is quite popular to treat hair thinning and receding hairlines. It is safer, non-invasive than hair transplant surgery, and tolerable.
The theory behind low-level light therapy hair is that the low-doses trigger circulation within the scalp and encourage hair follicle growth.
The LLLT devices used to treat hair loss have diodes that emit infrared light. These rays penetrate the scalp. The wavelength of infrared light is 630-670 nanometers. These devices are available as:
Some of the lasers used for LLLT are Excimer (308 nm), helium-neon (632.8 nm), and fractional erbium-glass (1550 nm). The hair growth cycle has three stages –
Low-level laser therapy causes an increased blood flow to the scalp. This stimulates metabolism in follicles that are in the catagen or telogen phase. As a result, this stimulation allows the hair follicles to reach the anagen phase. Basically, it stimulates or awakens dormant hair follicles to grow hair.
The photons emitted by the low-level laser beams act on cytochrome C oxidase. This causes the production of adenosine triphosphate (ATP) which converts to cyclic AMP in the hair follicle cells. This releases energy and consequently stimulates metabolic processes necessary for hair growth.
The light/heat treatment helps to release nitric oxide from cells. This leads to increased blood flow or vascularisation to the scalp. The vascularisation aids the distribution of nutrients and oxygen to the hair roots. Moreover, it also helps to reduce the perifollicular inflammation on the scalp.
Dihydrotestosterone (DHT) is one of the causative factors of androgenetic alopecia (AGA). LLLT prevents the excessive build-up of DHT.
Furthermore, it also acts on the sebaceous glands, reducing the oiliness in the scalp. As a result, LLLT may also help in reducing dandruff and dryness. So the therapy not only increases the growth of the hair but also the overall health of the scalp.
