Neutrolox is a product that claims to help with hair thinning and ringing in the ear. There are very few reviews out there for this product, but one review that exists oddly enough says it works very well. One customer even preferred it over doctor recommended products like Rogaine. This came from a customer who tried everything, including volumizing shampoos and conditioners. You can find some of their advertising pitch here.
Since there aren't many reviews regarding Neutrolox, you should be very careful using the product. There doesn't even seem to be a legitimate website for this product, so let the buyer beware!
Good news! New hair-loss treatments are on the horizon. Studies are being done on cell-based hair follicle regeneration which takes cells found around hair follicles and grows them in a lab. The cells are then re-injected into the scalp to help grow hair. Learn more from WebMD.
