What Is PRP for Hair Loss?

PRP is plasma enriched with platelets, proteins, and growth factors. Platelets are components of blood together with red blood cells and white blood cells. Platelets are among the first cells to arrive at the injury site in the human body and they play a major role in the human body healing process:

  • Participate in the blood clotting mechanism
  • Facilitate healing and cell growth

It is theorized that injecting platelets to the body part with damaged cells can help those tissues to be rebuilt and regrow. This is why plasma enriched with platelets (PRP) is commonly used for injections to damaged tendons, ligaments, muscles, skin, and other tissues resulting from sports injuries to enhance the healing process in those tissues. PRP used for the skin is also known as “vampire facial”.

It is thought that alopecia or hair loss is partially due to damage to hair follicles responsible for hair growth, and so injecting PRP might help reverse the damage to hair follicles, stop hair loss, and restore hair growth.

Is PRP Hair Treatment Effective?

According to several research studies in the last 5 years, there is some evidence confirming the effectiveness of PRP injection treatments for hair loss as compared to topical or oral supplement treatments. It has been shown that PRP injection treatments slow down hair loss and make existing hairs stronger by increasing the diameter of hairs and density of regrown hairs.

The number of platelets in the plasma affects the effectiveness of PRP treatments. If blood from which PRP is derived has fewer platelets, then PRP treatment might be less effective.

PRP is equally effective for both male and female patterns of alopecia or hair loss. PRP therapy is also often recommended after a hair transplant to sustain the results and encourage hair growth and strength.

Injecting PRP might help reverse the damage to hair follicles, stop hair loss, and restore hair growth.

PRP Hair Treatment Side Effects

PRP is mostly composed of a person’s blood components and so side effects of PRP injection therapy are very minimal and manifested mostly locally at injection sites:

  • Mild pain, tenderness, swelling at injection sites
  • Mild headache
  • Itching as a result of healing
  • Some bleeding and minimal bruising at injection sites

How Long Does PRP Hair Treatment Last?

PRP injection therapy is not curative for alopecia. It is more a maintenance therapy. Several treatments are normally needed, at least 3 to 5 to reduce hair loss and start the hair regrowth process. Follow-up PRP treatments every 3-6 months to maintain hair regrowth results of PRP therapy are usually necessary.

PRP Hair Treatment Procedure

Preparation of PRP for hair loss injections consists of the following steps:

  • A health care professional (MD, RN, NP) perform venipuncture and collects blood from the client’s vein in the arm
  • Collected blood in a vial is placed in a centrifuge where it is rotated for approximately 10 mins at a high speed.
  • During the centrifuge process, the blood separates into red blood cells, white blood cells at the bottom of the vial, and plasma enriched with platelets, proteins, and growth factors at the top of the vial forming golden-colored liquid – also known as “liquid gold”. This “liquid gold” is drawn into a syringe
  • The health care provider then injects PRP into scalp areas with hair loss

The process, starting with consultation, followed by blood collection and preparation of PRP and finalized by injecting PRP into the scalp, takes around an hour. At least 3-5 treatment sessions are recommended.

Before and After PRP Hair Treatment

It is recommended to avoid certain medications 24-48 hours before and after the PRP injection treatment to minimize bruising and bleeding at injection sites:

  • Aspirin
  • Ibuprofen(Advil)
  • Fish oil capsules or omega 3 supplements
  • Multivitamins as they may contain omega 3 And Vitamin E
  • Alcohol, especially red wine
  • Please eat your breakfast or snack before your appointment to prevent feeling lightheaded and dizzy due to the blood draw procedure

If you take other blood-thinning medications, you must consult your family physician about the possibility of stopping those medications before PRP treatments.

Please make sure you wash your hair before your PRP treatment, do not put any lotions or substances on your hair before your treatment.

After your PRP treatment please make sure to avoid saunas, pools, direct sun to allow injection sites to fully heal. Do not wash your hair at least 24-48 hours post-treatment. If you want to wear the head garment, make sure it is just washed and clean.
