Platelet-rich plasma, or PRP, is a regenerative treatment using cells harvested from you own body to tackle hair loss. PRP contains a range of growth factors and proteins that speed tissue repair and as some types of hair loss result from damage to hair follicles, researchers initially hypothesized that PRP could help regrow hair by reversing the process that occurs in androgenetic alopecia, the cause of male baldness PRP is harvested by isolating plasma from blood and concentrating it. The idea is that because tissue growth factors are more concentrated in the PRP injected into damaged tissues will stimulate your body to grow new, healthy cells and promote healing.

Here’s what to expect from a typical PRP injection treatment:

  • We will draw a sample of your blood. The amount of the sample depends on where the PRP will be injected. For example, the amount of blood taken for injection into the scalp for one studyTrusted Sourcewas 20 milliliters. This is slightly larger than one teaspoon.
  • The blood is placed into a centrifuge. This is a machine that spins around very quickly, causing the blood components to separate. The separation process takes about 15 minutes.
  • A technologist takes the separated plasma and prepares it for injection into the affected area.


The entire process may take about 1 hour, and several sessions may be necessary. After receiving PRP treatment, a person can usually return to their regular activities without any limitations.
