The genhair is to be used twice daily, which lasts for 3.5 months. Dr. Lee's is to be used once daily, which lasts just over 4 months. Basically the same price. I dont use either since kirkland 5% is dirt cheap.
I went to HCM also before i was knowledgeable about hair loss. They are basically selling you nioxin shampoo/conditioner, a multivitamin, and some herbs. Total waste of money!
