Rogaine 5, or minoxidil, is a topical solution used to treat hair loss and promote hair regrowth. Discovered in the late 1950s, minoxidil was initially used to treat hypertension. However, it was soon discovered that it had the unintended side effect of promoting hair growth. In the late 1980s, the drug was approved by the FDA for the treatment of male pattern baldness.
Rogaine 5 contains 5% minoxidil, which is the highest concentration available without a prescription. It is available in a foam or liquid form, and is applied directly to the scalp twice a day. It has been clinically proven to be effective in promoting hair regrowth and reducing hair loss, although results may vary.
The active ingredients in Rogaine 5 are minoxidil, propylene glycol, hydroxypropyl cellulose, and alcohol. Minoxidil is the main ingredient and is responsible for promoting hair regrowth. Propylene glycol is a moisturizer, while hydroxypropyl cellulose helps to thicken the solution. Alcohol is used as a preservative.
Other names for Rogaine 5 include minoxidil topical solution, minoxidil topical foam, and minoxidil topical aerosol. It is available over-the-counter in many countries, and is generally considered safe when used as directed. However, it is important to speak with a doctor before using Rogaine 5, as it may interact with other medications or cause side effects.
