What is PRP therapy?
PRP (platelet-rich plasma) therapy for hair loss is a three-step medical treatment in which a person’s blood is drawn, processed, and then injected into the scalp.
Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications.
How long does it last?
PRP is not a cure for conditions that cause hair loss. For this reason, a person would need to receive multiple PRP treatments over time to maintain hair growth results. The same is true of medications that doctors commonly use to treat androgenetic alopecia, such as topical minoxidil (Regaine) and oral finasteride (Propecia).
The doctor’s recommendations for how often a person should have PRP will vary depending on a person’s condition and the results of their initial treatment. The doctor may suggest having maintenance injections every 3–6 months once hair loss is under control.
PRP injections for hair loss: Before and after
Keep in mind that results will look different for everyone based on overall health, blood platelet levels, and hair health. Here’s an example of a person who saw successful results from PRP injection treatments for hair loss.
The following steps are an example of a common approach to PRP injections for hair loss:
- A medical professional draws blood from a vein in the arm.
- They place the blood sample in a centrifuge.
- The centrifuge spins the blood, separating its components.
- A medical professional extracts the platelets using a syringe.
- A doctor injects the platelets into targeted areas of the scalp.
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.
