There are only two medications with FDA approval for use in hair loss treatments. The two hair loss products that have this approval for hair loss prevention are advertised as Rogaine and Propecia (common names).
Rogaine may be purchased over the counter at a local drug store while Propecia requires a prescription. Both of these hair loss products can be shown to increase some hair growth but is meant for use as hair loss prevention and the difference occurs with the way the drugs are administered, the cost and the side effects.
Rogaine must be applied twice a day every day and many tire of this requirement. Propecia on the other hand is a pill that is taken once a day. This would entice more to desire Propecia over Rogaine until the cost factor and the side effects of a hair loss medication is taken into consideration. The cost of Propecia as well as the cost of the doctor’s visit many times creates the decision to use Rogaine over Propecia even if it must be applied twice daily.
The side effects of the two would suggest that this may be the wiser choice as Propecia also had a side effect of impotence. The normal sex drive will return if you stop taking the hair loss medication. The decision on ease of purchase, cost and use along with the lack of the major side effect make Rogaine the most common choice.
Neither of these are permanent hair loss treatments and the only permanent solution can be found in surgical hair transplants. Transplants have been successful for more than 40 years. One of the benefits of a hair transplant is that the hair will continue to grow. Today a method of hair grafts are used in place of the “plug-style” transplants that were come when the procedures were first developed.
