The present invention relates to a therapy helmet, particularly to a light based therapy helmet.
The prevention and treatment of hair loss and the promotion of healthy hair growth have long been the directions toward which the medical community's continuous efforts are pursuing. After the prevalence of laser technologies, the medical community tried to use low-dosage laser light sources to irradiate the scalp to prevent hair loss and promote healthy hair growth. Therefore, a medical laser hair growth device was developed. The medical community has also tried to use Light Emitting Diode (hereinafter referred to as LED) as a light source to illuminate the scalp to prevent hair loss and promote healthy hair growth. The above-mentioned phototherapy is effective for seborrheic alopecia, female postpartum alopecia, alopecia areata and hair loss after chemotherapy, etc. Moreover, the above-mentioned phototherapy can improve oil secretion, minimize the possibility of hair loss, prevent hair thickening, and make the hair more plumping and shiny. The above-mentioned phototherapy can also promote the hair to fully enter the growth phase, penetrate deep into the hair follicles, increase the number of hair follicles, and strengthen the hair roots.
Nowadays, devices in the market that utilize light to irradiate the scalp to prevent hair loss and promote healthy hair growth usually include far infrared light sources provided by far infrared light emissions from ceramic elements or particulate films after their heat absorption; nevertheless, the far infrared light sources may also be directly provided by the LEDs.
