Your hair goes through several distinct phases as it grows. Together, these phases are referred to as the hair growth cycle, or hair growing process. During the anagen phase of the cycle, your hair grows to its full length. Research shows that 85 to 90 percent of your hairs are in this phase at any one time.
On average, the anagen phase of the hair growth cycle lasts for two to six years, during which your hair grows continuously. As your hair grows to its full length, it moves from the anagen phase into the catagen phase, in which the hair detaches from your scalp. Next, the hair enters into the telogen phase, in which the entire hair structure rests for several months. Finally, the old hair fully detaches and sheds from your scalp, with a new hair growing out from the hair follicle to replace it.
Minoxidil shortens the telogen phase of this cycle, meaning your hairs spend a shorter amount of time at rest. It also lengthens the anagen phase, or growth phase, and stimulates your hairs to enter into this phase earlier than they normally would. Minoxidil also appears to improve blood flow to your scalp, which may help to supply your hairs with the nutrients they need to grow to their full potential.
Because minoxidil causes your hairs to prematurely enter into the anagen phase of the growth cycle, it may cause your hair to look worse before it looks better.
By this, we mean that you might notice that your hair loss increases during the first few weeks or months of treatment with minoxidil. This is because your hairs need to rapidly go through the telogen and shedding phases of the hair growth cycle before starting the anagen phase.
When you first begin using minoxidil, you may notice more stray hairs on your pillowcase or in your hairbrush than normal.
