I had a lot of hope on this shampoo. But after using this N2 shampoo for 2 weeks now the results are not looking good. I noticed more hair loss than with Pantene shampoo. Before using this N2 my hair length that falls out were an inch long or more. After using N2 I noticed my hair length that falls out is now 1/4" long.This stuff is killing my hair root or something. I followed the instruction on the label since using the shampoo. I want a refund.
