Many people are using the Regenepure shampoos to stop hair loss and potentially grow hair due to the ingredient Ketoconazole that is found in the DR product.  The NT (Nourishing Treatment) has many great conditioning agents and people are using it in place of their conditioner.
Ketoconazole has a drying effect for certain users so they are using that product first.

The Regenepure shampoos use only the finest ingredients for the scalp and hair.  Most store brand shampoos use a harmful foaming and cleansing agent called sodium laureth sulfate.  That is a very popular foaming agent that the Regenepure products would never add.
