Unfortunately, the Nood Flasher has been a complete waste of money and time for me. I have the ideal coloring for treatment - fair skin and dark, thick hair - but saw absolutely no results. I followed all the directions, from the skin test to exfoliating before and cooling lotion after. I have now done 36 treatments over about 21 weeks - more than double the recommended treatment phase - but there has been no reduction in hair growth at all. The hair has not even started growing more slowly or thinner. The Nood Flasher simply has not worked for me at all. Super disappointed.
