Even if you're thinning it could be so minor that it wont even show until your 50+ years old. Just because you're thinning now doesn;t mean your going bald. Hair loss is a complicated issue and people want to take finasteride to help or even more extreme dutasteride(spelling?). Doctors all over recommend that you should only take that when you're 30+ years old.
If you have a family history of MPB then stay away from test products as it will only hurt you more in that department. Why not try Laser comb http://www.lasercomb.net/intro/intro...FQIgPAodrlq7Kg
There is an exact copy of this item for A LOT less. http://www.amazinglasercomb.com/
Other than that some people thin for a little and it stops. Sometimes you shed a lot of hair during the summer but nothing
in the winter. Just look at your moms brothers and father, take a gauge there.
