I am losing hair with Excimer laser treatments

What do you think about UVB Xtrac (excimer laser) that is supposed to kill down the inflammation of the scalp. I have severe sebhorric dermatitis and had 15 sessions of that laser when my itch was unbearable, it made the itch go away, but I wonder if the UVB itself shrink down the hair follicle or makes it age very fast where it slips out of the hair bulb ?

There are reports that the excimer laser can produce hair loss as its wavelength is in the lower ranage, outside the range recommended for hair regrowth.  The excimer laser is used for inflammation with a wavelength of between 193-350 nm.  The UV wavelength of light for hair loss is not recommended, but rather the higher wavelengths of between 600-1200 nm, as shown in the chart below.
