Yes in some cases of pattern balding it does help control the hair fall and increase hair growth. Low level diode laser (LLLT) therapy uses cap like devices with diodes that need to be worn over the scalp. LLLT devices are also available in the form of combs, hands held devices and saloon hoods. You can do this hair growth therapy at home or in a professional saloon. The LLT device emits low wavelengths of red light or infrared radiation that irradiates photons to the scalp tissues. The light penetrates the scalp and is absorbed by the weak follicle cells to promote hair regrowth. The laser treatments increase the blood circulation to the hair follicles.
