    Really great product.
    Review by on
    I have had very fine hair all my life and in addition I have very little of it. I have probably used every product you can think of and also visited a tricologist for help. nothing has worked for me. Nanogen Root Boost is the best product I have come across.
    Although I will never have luxuriant hair this product gives me as much volume as I can get. It also protects against damp presumably because it coats the hair . I cannot do without it and wish I had discovered it years ago.
