Red light therapy is the alternative treatments that have proven to be highly effective in the treatment of hair loss. Red Light Therapy is an all LED light solution that evenly bathes the scalp in precise wavelengths of light to boost the revival and regeneration of new hair follicles. The doctors in Beijing Hospital did the clinic trial to define the safety and physiologic effects of Red light therapy on males alopecia or seborrheic areata with androgenic alopecia.
Also known as cicatricial alopecia, it often occurs suddenly, with round or oval hair loss spots on the scalp, without any symptoms, and most patients find it unintentionally. The onset is divided into three phases: the progressive phase, the quiescent phase and the recovery phase. The number of hair loss varies, and the scalp in the hair loss area is normal without redness, scaly, and scars. The hair at the edge of the hair loss area in the static period is no longer loose, and no new hair loss spots appear. Most patients enter the recovery period after a quiescent period of 3 to 4 months. During the recovery period, new hairs will grow out. Initially, they are soft and light-colored hairs, similar to vellus hairs, which gradually become thicker and darker over time, and then return to normal. There are also severe cases where large areas of hair loss merge into total baldness, and even all eyebrows and beards fall off, which is called general baldness. Its pathogenesis is not yet clear, and it is more likely to be an immune disease.
Alopecia areata can be treated with hormones, thymosin, anthralin ointment, etc. At the same time, patients should maintain a good mood and get enough sleep.
The etiology is related to heredity. Androgenic cord and seborrhea. The patient manifests as excessive secretion of oil on the scalp, and the hair feels greasy. If it is not washed for a few days, it will give off a foul smell. Scalp itching is the main symptom. Excessive sebum secretion oppresses and blocks the hair follicles, and the oleic acid and linoleic acid secreted by it have toxic effects on the hair follicles, leading to hair poisoning and wilting. Seborrheic alopecia mostly occurs in the strong secretion of sebaceous glands. The young and middle-aged, gradually developed into "balding".
Seborrheic alopecia should pay attention to hair care and diet such as vitamin B. Use less irritating shampoo and so on.
