It is possible to stop hair loss using foams, pills or lotions, according to WebMD. Minoxidi, or Rogaine, is an over-the-counter lotion, while Finasteride, or Propecia, is a pill that requires a prescription.
Minoxidi comes with few downsides, such as the need to apply the lotion twice a day indefinitely. It may also cause irritation, flaking or redness in users with sensitive scalps. The lotion stimulates hair growth within four months of starting to apply it. On the other hand, Finasteride pills manipulate regressive hormones to halt hair loss. WebMD states that the medication helps up to 90 percent of users regain a significant amount of their hair.
