I purchased this and have used it off and on now for over 6 weeks, only approx. 3 times per week. Within the first 3 weeks I noticed that my hair was not falling out in as large of clumps as it had for the past couple of years. Within next couple of weeks the hair loss during showering/towel drying off and/or hair brushing was significantly reduced and within normal limits. I will continue to use this product if for nothing else for this amazing result and am confident that even more positive results will start to show.
