I have been using this product for years after a hairdresser recommended it. It does help make my hair look a bit thicker. Of course it isn't it just makes it look that way.

Great product for thinning hair. I have seen a huge improvement. My hairdresser loves the results as well. I used to have very thin hair and started using this about 8 years ago. No more thin hair and I hardly lose any hair now from washing.
