How PRP Can Promote Hair Growth

How PRP Can Promote Hair Growth

Did you know you have over a gallon of blood in your body? Your blood travels throughout your body, delivering oxygen and nutrients to your cells. It’s essential in keeping you alive.

Your blood also has miraculous healing properties that can help regrow hair in bald and thinning areas. Platelet-rich plasma (PRP) therapy is a cutting-edge treatment using a concentrated blood sample to stimulate hair growth in dormant follicles. Get thicker, fuller hair and boost your confidence in just 3 months.

The hair specialists at Hair Doc, located in Cow Hollow, San Francisco, are here to tell you everything you need to know about PRP and how it can replenish your hairline.

How it works

Baldness. It often starts at the top of your head. Then it forms around the temples before forming a horseshoe-like shape on your head. 

Do you wear hats to hide your baldness? If yes, you’re not alone. Nearly 66% of men experience balding by 35, often before other signs of aging occur. If you wish to regenerate hair in an easy, minimally invasive way, PRP may be for you.

When you come in for your appointment, Peter Panagotacos, MD, explains the procedure and answers any of your questions. He starts the procedure by drawing a small blood sample from your arm — around two ounces.

Using a centrifuge, Dr. Panagotacos spins the blood sample to separate your blood’s components. This process allows the plasma to rise and the PRP to move to the bottom. Next, he draws the PRP into a syringe and administers it into places on your scalp experiencing baldness. 

The whole procedure takes about an hour and while you’ll notice an improvement after the first procedure, most patients need three treatments for optimal results. Not only will you notice more hair, but thicker and stronger hair, too.


PRP isn’t a new treatment. In the 1970s, PRP was first used for open heart surgery and wound healing. Today, its network has expanded to heal various musculoskeletal injuries in addition to facial rejuvenation and hair restoration.

Some of PRP’s benefits include:

Effective hair loss treatment

We’ve seen firsthand how PRP can help our patients get hair they can run their fingers through. However, PRP has been proven effective in various past and ongoing clinical studies to back this.

A study in 2014 found PRP increased the number of follicular unit hair grafts in patients from 71 to 93 units. Another study dating to 2019 compared PRP with Rogaine™, another leading hair loss treatment. The patients using PRP saw a much greater improvement in hair regrowth while offering minimal side effects.

No downtime

You probably can’t put your life on hold between work, family, and social life. While hair transplant procedures require around two weeks of downtime, PRP requires no recovery period. PRP is nonsurgical and minimally invasive, so no one will know you had a procedure unless you tell them.

Natural treatment

Rogaine and Propecia® are medications that can come with some side effects. Because PRP uses your blood, you don’t have to worry about any adverse treatment reactions and little to no side effects. Plus, you can feel safe undergoing it because no harmful chemicals or additives are involved.

Little discomfort

While injections on your scalp may not sound pleasant, most patients tolerate it well, describing it as having little to no discomfort. The injection portion only takes minutes, so it’s finished with before you know it with no lingering pain. This makes it a great option for patients with low pain tolerance.

The power of platelets

Your blood is composed of four main elements — red blood cells, white blood cells, plasma, and platelets.Platelets are the smallest of the four components responsible for clotting your blood. They’re also high in growth factors, a group of proteins that aid your body in cellular turnover and tissue regeneration.

PRP uses a concentrated blood sample containing over five times more growth factors than found in normal blood. Platelets are the key factor in PRP, stimulating the dermal papilla and providing it with increased nutrition and blood supply for stunning new hair growth.
