It takes time but definitely helps
I bought this at a deep discount at a JC Penny's that was closing.  I don't normally buy salon shampoos but hair has been thinning for years and I hoped this would help.  It took 3 months before people started commenting on how great my hair looked!  I noticed a difference after 6-7 weeks - just shinier and easier to manage, but after 3 months there is no denying it has helped with the thinning.  I bought the big containers after deciding I couldn't go back to regular shampoo now.  I am a life-long user!
