Chin hair not cleared up completely after first Diode laser hair removal sitting. Small thick hairs are visible (Photo)

Hi..got my first session of hair removal on chin today but the area doesnt seem to have cleared uo compketely as it still has tiny coarse hair. I have a fair skin with dark coarse hair growing very frequently making me threda them evry 4 days, , hence opted for laser. Pls suggest if this is how the skin looks aftrr first session or the laser hasnt been done properly? Its looking like its been shaved and nothing else.
