minoxidil shampoo polar nr-02


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)


There are conflicting information about what is in this shampoo. You may read somewhere that says it has 1% finasteride, which is not correct. It has only 0.05% finasteride.  The complete ingredients are listed below.

Deionized water (pure water) 64.3%

Sodium lauryl sulfate 12.0%

Aloe vera leaf extract 6%

Cocamidopropylbetaine 5.2%

Alpha-olefin sulfate 5.0%

minoxidil 1.0%

How to use:

Wet your hair completely, apply shampoo, generously lather, and rinse thoroughly. Apply shampoo again, gently massage into hair and scalp for 1 minute. Leave shampoo in for 1-2 minutes. Different from a ketoconazole shampoo that is typically recommended to use every other day, this shampoo is recommended to use daily.   


Special Note:

The shampoo is for men only. The product can not be used by women because it has finateride.
