Didn't do much for my hair
Hoped product would improve my hair and it does somewhat, but seems a bit heavy on my hair.  Haven't done the 5 min treatment, only 2-3 minutes, when I'm showering, wash my hair, put this stuff in and then continue with my shower, which only takes a few minutes.  It does help hair comb out with no tangling, but can get that with any good conditioner.  I do need to address their sales/customer service actions - received email asking about the product, if I was happy with it, etc, and responded that I hadn't tried it yet, and after trying a few times would leave Amazon review.  In the next couple of weeks I received 3 more emails, which I found annoying.  So I'll say the product was okay, sales follow up was very annoying.
