I've been using it for nearly 3 months. Actually, a week from yesterday will make 3 months, exactly. I'm not even halfway through the bottle and I use it daily. I don't have crazy long hair, but it's not short, either, by any means (if you go into one of the AX Halloween promo threads, you can see that I was able to pick out a pretty good-sized afro for my costume). What I noticed was less hair in my hands when washing it after several weeks of use. I wouldn't say my hair is a whole lot thicker because of it, but it hasn't gotten worse. My problems likely stem from a (currently undiagnosed) medical problem, so there still is shedding, but like I said, it's not as bad. To further illustrate this, I used to get my hair cut about every 2 weeks. I've had it cut once since May 15th. A couple years ago, my hair would probably be twice the length it is in this amount of time. So there is definitely something going on that's beyond the help of a shampoo, but it still has helped a bit.
CEDeoudes59 is probably the most knowledgeable guy in this area that I've seen on the forum. While you can say he was running a lot of products (I don't recall what else he was taking/using at the time, and I'm not gonna go read back through his log), he didn't make any changes and within a few weeks he sounded pretty pleased with his results.
What I can say in short about this product is:
- It's expensive versus regular shampoo at Walmart, sure, but compared to some other shampoos in the same category, it's not bad considering it can last up to 6 months used daily.
- It definitely has helped minimize my shedding.
I wouldn't expect miracles from it, but it's certainly noticeable. I bought it with my own money the day that it came out and I'll buy it again when I run out of this bottle (presumably sometime in March).
