Let's see... I had a pretty full head of hair in my late 30's but I started to notice a general thinning of my hair at the vertex/crown and at the front in my early 40's. In November 2010, I started using Equate Extra Strength as well as washing my hair twice weekly with Nizoral Shampoo. When I first started using Equate, I experienced "shedding", which is a normal reaction where you notice an increase in hair falling out (nothing too drastic, mind you, but a few more strands than usual were left in my hands after lathering). After a few weeks, the shedding stopped and by 2 months I noticed new hair growing in the thinning areas. The new hair was finer, which again is a normal experience for most folks that experience hair regrowth. It's now been 6 months since I started and I just bought 2 more 3-month supplies. The new hair is thicker now and my hair is quite a bit fuller than it was. I am very pleased with the results. For those that are thinking of trying this product, do not expect instant results (in fact, prepare for that first inevitable shed). Applied regularly and properly over the course of 4 to 6 months you should start to see noticeable results. Good luck!
