Your BBL treatment can be tailored to target and disable course hair, medium hair and fine hair by utilizing the correct wavelength to penetrate to the appropriate depth of the follicle for each type of hair. Unfortunately, because the pigment in the hair is what the light is attracted to, hair without pigment does not absorb the energy. To date there is no laser or light- based technology that can treat white or very light coloured hair. Also, as the light that reaches the appropriate depths to target hair is red, it is reflected off pigment of the same colour. Thus, lightly coloured red hair cannot be successfully treated.
