Polaris Research Laboratories's NR-02 shampoo is one of the most interesting hair loss products on the market. It is marketed as a minoxidil shampoo.  It has the two powerful ingredients minoxidil and finasteride in it. However the effectiveness is very questionable, reason being the contact of product with the scalp is just too short to be absorbed. Not sure why Polaris chose to use finasteride instead of a more popular ingredient ketoconazole in this shampoo like Lipoggaine big 3 shampoo. There is no clinical study that shows finasteride in a shampoo is effective. On the contratry, ketocoonazole shampoo has been very well studied and has been proven to slow down hair loss or even grow hair like minoxidil (see here) 

Size of the Shampoo:

7 oz (210 mL)
