I joined the forum in case my info may help.
I have been using nioxin for a few months, the shampoo, conditioner and scalp therapy serum, and I have seen real results. My hair stylist has also noticed a difference in the volume of my hair. I have had thinning hair for a while, it seems to have come in different stages but I never lost enough to get a bald spot, and I would rather find a non-prescription method to deal with my thinning hair. I think you need to be really aware of your hair to see the difference, because the changes are extremely gradual. The pull test is always a good one, where you run your fingers through your hair in a comb fashion and try to gently yet firmly trap hairs between your fingers and then count how many hairs are left in your hands. I used to be able to pull about 10 to 12 on average, and now, its between 0 and 2. I also noticed alot of hairs on my towel after drying my hair before using Nioxin, and that all almost stopped in the first few weeks of using Nioxin, and my hair stylist also noted that my hair is thicker. I even got comments from colleagues that I don't see that often that my hair looked "darker", and they asked if I dyed it, which I did not. It is expensive for the set of shampoo, conditioner and serum, around $100 (in Canada) but it was bought 3 months ago, and I still haven't finished it. Another hair stylist had recommended it to me, stating that he actually re-grew hair with it, and he proudly showed me a new front hair line growing in.
That being said, I am going to try Triaxon next, since its supposed to work in the same manner, and it boasts clearer results, and seems like a more comprehensive system. Its also less expensive, they had a promotion on the Canadian shopping channel for a 7 piece kit for $69, which is apparently enough to last you 6 months. If I am not as successful with Triaxon, I will go back to Nioxin. The Triaxon also has a 6 month money back guarantee, and is now being manufactured in Canada, where they claim to have developed a loyal client base. They sell primarily through theshoppingchannel.com and have been working with them for 8 years now. They do boast a 91% success rate, but that would be that 91% had "some" results, not everyone will have dramatic results. The spokesperson said their return rate 6.5%, which they deem is reflective of their studies of the proportion of the population that would receive little to no benefit.
My one concern is that they don't tell you exactly what the active ingredients are, and why and how they work, or at least, it was not clearly explained. I would be interested to know exactly which of the components is a DHT blocker.
I recommend that people try Nioxin (or Triaxon) so long as you do carefully monitor your hair to know if it is actually making a difference or not, and use it regularly and long enough, preferrably about 3 months at least. Also, let your hair stylist know also, or ask him or her if they have noticed anything. I think these costs are not very high when you consider how long the supply lasts (so long as you'Re the only one using it!), and that you need shampoo and conditioner anyway, and why not use good quality products.
I hope this is of some assistance.
