| abstract |
Disclosed are methods and apparatus for treating hair. The method includes irradiating the skin treatment site with electromagnetic radiation (EMR) to provide energy to one or more hairs to alter the shape and / or chemical structure of at least a portion of the hair. By irradiating with radiation, the hair apex can be heated to correct its shape (for example, the sharpness is made blunt). Hair modification can include changing the shape, composition, or function of the hair tips, hair shafts, and / or hair matrix by heat, making it difficult to re-enter the skin. The methods and devices of the present invention can treat and / or prevent false hair follicles (PFB) at the treatment site. Also disclosed is a method for controlling hair growth using wavelengths in the range of 1200 nm to 1400 nm. |
