How PRP Works at a Cellular Level to Promote Hair Growth

How PRP Works at a Cellular Level to Promote Hair Growth

Hair loss affects millions of people worldwide, and despite numerous treatments, finding an effective and lasting solution often seems elusive. Enter PRP—Platelet-Rich Plasma—a new and clinically promising method for promoting hair growth. Valley Skin Institute, renowned for its expertise in PRP treatments, is at the forefront of bringing this innovative solution to those battling hair loss.


Understanding PRP

PRP, or Platelet Rich Plasma, is a concentration of platelets in plasma, the liquid part of blood. Platelets, typically known for their role in clotting blood, are also rich in proteins called growth factors, vital for healing injuries.


PRP is derived from a person’s blood. The process begins by drawing a small volume of the patient’s blood. This blood is then put into a centrifuge, a machine that spins at a high speed to separate different components of the blood based on their densities. After a series of centrifugations, the plasma containing a high concentration of platelets—the PRP—is separated and ready to be used.


Platelets play a crucial role in our body’s healing process. They are the first to arrive at an injury site, helping to stop bleeding and start the repair process. But beyond clotting, platelets also release growth factors. Growth factors are proteins communicating with cells, signaling them to perform specific functions. In the case of PRP, growth factors signal cells to increase collagen production, develop new blood vessels, and stimulate stem cells, leading to tissue regeneration and faster healing.


In the context of PRP for hair growth, these growth factors work at the cellular level in the scalp, stimulating the hair follicles to promote healthier and fuller hair.


Understanding PRP is the first step to appreciating the science behind this innovative solution for hair loss. It’s not just a trend—it’s a treatment grounded in healing, revitalizing, and growing biology.


The Science Behind PRP for Hair Growth

Diving deeper into the science of Platelet-Rich Plasma therapy reveals a fascinating process by which the body’s healing capabilities are harnessed to promote hair growth. This section breaks down the cellular-level mechanisms through which PRP works.


At a cellular level, PRP releases growth factors near hair follicles. These growth factors interact with the cells in the scalp, promoting various processes that facilitate hair growth.


The growth factors in PRP play a vital role in stimulating hair follicles. These unique proteins bind to specific receptors on the cells in the hair follicles, triggering cellular activities conducive to hair growth. Essentially, these growth factors ‘wake up’ dormant hair follicles, encouraging the production of new hair.


The hair growth cycle consists of three phases: the anagen (growth phase), telogen (resting phase), and catagen (transition phase). The growth factors in PRP are believed to prolong the anagen phase of the hair growth cycle, leading to longer, thicker hair strands over time.


PRP’s Role in Reducing Inflammation and Improving Blood Flow to the Scalp

Beyond stimulating hair follicles and prolonging the anagen phase, PRP also contributes to a healthier scalp environment by reducing inflammation and improving blood flow. Inflammation can damage hair follicles and hinder their ability to produce healthy hair. By reducing inflammation, PRP helps create a more conducive environment for hair growth.


Improved blood flow is also fundamental for hair growth, as hair follicles need constant nutrients to produce hair. PRP can stimulate the formation of new blood vessels, improving the supply of nutrients and oxygen to the hair follicles.


Understanding these scientific aspects of PRP elucidates why this novel therapy is revolutionizing hair growth treatments. It’s all about empowering the body’s cells and biological processes to restore hair health.


The Procedure

PRP treatment for hair loss is a straightforward process typically completed in an hour or less. Here is a close look at the step-by-step procedure:


  1. Drawing Blood from the Patient: The process begins with drawing a small amount of blood from the patient, similar to a regular blood test. This blood is then placed in a centrifuge, preparing it for the next step.
  2. Centrifugation to Separate Platelets: The collected blood is centrifuged and spun rapidly. The centrifugal forces generated in this process separate the different components of the blood based on their densities. As a result, we get PRP—a concentrated layer of plasma rich in platelets and growth factors.
  3. Application of Local Anesthetic: To keep the patient comfortable during the procedure, providers at Valley Skin Institute apply a local anesthetic to the scalp before injecting the PRP.
  4. Optional Microneedling: Microneedling is an optional step that can be incorporated into a PRP session. A device with tiny needles is rolled over the scalp during this process. These micro-needles create tiny injuries on the scalp, triggering the body’s natural healing response and further stimulating hair growth. Microneedling also enables better penetration of PRP into the scalp.


While the PRP treatment process may sound intensive, patients tolerate it well. Each session is a step forward in the journey towards healthier hair and restored confidence.


Results and Efficacy of PRP for Hair Growth

While PRP for hair growth is relatively new, initial studies and patient experiences have been highly promising.


Clinical studies into the effects of PRP on hair density and thickness have generally shown positive results. Patients treated with PRP typically see a noticeable increase in hair follicles, leading to improved density. The hair strands often become thicker and stronger, contributing to a fuller head of hair.


PRP for hair growth isn’t a one-and-done treatment. For optimal results, multiple sessions are needed. The precise number depends on the individual’s hair loss severity and unique response to treatment, but typically, patients undergo a series of sessions over several months. This repeated stimulation helps maintain the growth phase of the hair follicles, leading to sustained hair growth.


Like any treatment, the results of PRP can vary among individuals. Many factors can influence the outcomes, including the underlying cause of hair loss, individual health status, and lifestyle factors like nutrition and stress. Patients need to have realistic expectations and understand that while PRP has helped many people improve their hair growth, it isn’t a guaranteed cure for all types of hair loss.


Maintenance and Continuity

Long-term success with PRP hair growth treatments requires more than attending appointments. Here, we discuss the role of patience, consistency, and customization in successful PRP therapy.


Regrowing hair with PRP takes time. It takes time for the body to respond to the growth factors and for new hair to grow. Therefore, patience is vital when undergoing PRP therapy. Additionally, consistency with PRP sessions is crucial. Skipping appointments or spreading them out too far apart can diminish the cumulative effects of the treatments.


At Valley Skin Institute, we understand that everyone’s experience with hair loss is unique. Therefore, the PRP treatment plan should be, too. Each patient’s PRP plan should be tailored to their specific needs, factoring in the extent and pattern of hair loss, overall health, and treatment goals.


Sometimes, PRP is part of a broader treatment strategy. Depending on the patient’s situation, pairing PRP therapy with other treatments, such as prescription medication, nutritional supplementation, or lifestyle modifications, may be beneficial. Such a multi-faceted approach can enhance the effects of PRP and lead to more significant hair growth improvements.


In conclusion, successful PRP treatment requires a commitment to the process, but the results – a fuller, healthier head of hair – are well worth it. At Valley Skin Institute, we’re here to guide you in your journey every step of the way.


Discovering the Power of PRP for Hair Growth

PRP has emerged as an exciting and effective treatment for hair loss. By harnessing the body’s healing capabilities at a cellular level, PRP stimulates hair follicles and boosts hair growth.
