Platelet-Rich Plasma (PRP) Therapy in Hair Loss Treatment

The Role of Platelet-Rich Plasma (PRP) Therapy in Hair Loss Treatment: A Scientific Perspective

Hair loss is a common issue that affects millions of men and women. It can be caused by genetics, hormones, lifestyle, or environmental factors. One of the newer treatments gaining attention is Platelet-Rich Plasma (PRP) therapy in hair loss treatment, which uses your body’s own healing power to obtain thicker and stronger hair quality. In this blog, we’ll break down the different types of hair loss and explain how PRP therapy can help.

 

Types of Hair Loss

Hair loss, also called alopecia, comes in different forms, and each type needs a specific approach. PRP therapy has shown positive results for the following types:

• Male Pattern Baldness: This is the most common type of hair loss in men. It often starts with thinning at the hairline or on the top of the head. PRP therapy can slow down hair loss and help stimulate hair growth by “waking up” inactive hair follicles.
• Female Pattern Hair Loss (FPHL): For women, hair thinning happens more evenly across the scalp rather than just in one area. PRP therapy has helped many women regain hair density and thickness.
• Alopecia Areata: This is a condition where the immune system attacks the hair, causing patches of hair to fall out. PRP therapy can help by calming the immune system and reactivating the hair follicles to regrow hair.
• Telogen Effluvium: Stress or hormonal changes can cause this temporary hair loss, where hair sheds excessively. PRP can help jumpstart the hair’s growth cycle, speeding up recovery.
• Traction Alopecia: Tight hairstyles, like braids or ponytails, can damage hair follicles over time. PRP therapy can help repair some of this damage if treated early.
• Scarring Alopecia: This type of hair loss involves scarring, which damages the hair follicles permanently. PRP might help reduce inflammation and protect the remaining hair follicles, though it can’t fix scarring that has already happened.

 

Common Causes of Hair Loss

There are many common causes of hair loss, and PRP therapy can help address several of them. Genetics play a significant role, especially in conditions like male and female pattern baldness (androgenic alopecia), which are often inherited. Hormonal imbalances, such as those caused by thyroid issues, PCOS, or changes after pregnancy, can also lead to hair thinning. Some medications, like chemotherapy, certain blood pressure drugs, and antidepressants, list hair loss as a side effect. Nutritional deficiencies, including low levels of iron, zinc, vitamin D, or biotin, can weaken hair and make it prone to shedding. Stress, whether physical or emotional, can disrupt the hair growth cycle and cause temporary hair loss, a condition known as telogen effluvium. Finally, environmental factors such as the use of harsh hair products, over-styling, and exposure to excessive heat can damage hair and lead to thinning. In these cases, PRP offers restorative benefits, helping to repair the damage and promote healthier hair. It is important to address the underlying cause of the hair loss to get the best results from PRP treatment. PRP will target the problem locally by promoting blood flow, strengthening follicles and encouraging new hair growth which will lead to healthier hair and scalp quality.

 

Popular Treatments for Hair Loss

There are several treatments available for hair loss, but PRP therapy has become popular because it’s minimally invasive and effective. PRP therapy works by taking a small sample of your own blood, processing it to concentrate the platelets, and injecting the plasma into your scalp to help stimulate hair regrowth. This is done by activating inactive hair follicles and improving blood flow. Other common treatments include medications like minoxidil (used on the scalp) and finasteride (taken as a pill), both of which are often prescribed to slow hair loss and encourage regrowth. Hair transplant surgery offers a more permanent solution by moving hair from areas with thicker growth to those that are thinning. Non-invasive treatments like low-level laser therapy (LLLT) are also becoming more popular, using light to boost hair follicle activity. For those looking for a cosmetic solution, scalp micropigmentation can create the look of fuller hair.

 

What Happens During Hair Loss?

Hair grows in a cycle with four stages: the growth phase (anagen), the transition phase (catagen), the resting phase (telogen), and the shedding phase (exogen). Normally, hair follicles move through these stages in balance. However, when something disrupts this cycle, hair loss can happen. In conditions like androgenic alopecia (male or female pattern baldness), the hormone DHT shortens the growth phase, making hair follicles shrink over time until they stop producing new hair. In alopecia areata, an autoimmune condition, the body’s immune system mistakenly attacks hair follicles, causing patches of hair loss. Stress-related conditions like telogen effluvium push many hair follicles into the resting phase all at once, leading to noticeable shedding.

 

How does PRP Stimulate Hair Growth?

PRP therapy helps stimulate hair growth by using the body’s natural healing factors to repair and regenerate hair follicles. PRP is packed with growth factors that improve blood flow, encourage hair follicles to move into the growth phase (anagen), and boost scalp health. It also promotes the production of collagen, which strengthens the scalp and creates a better environment for hair growth. By waking up dormant hair follicles and increasing their size, PRP improves the chances of strong hair regrowth. Additionally, it helps repair tissues, reduce inflammation, and promote the formation of blood vessels, all of which lead to thicker, stronger hair.

 

What Happens After PRP Treatment?

After PRP treatment, your body starts to heal and repair the scalp. Right after the procedure, you might notice some swelling, redness, or tenderness at the injection sites, but these symptoms usually go away within a few days. In the first 24-48 hours, the growth factors in the PRP begin to activate the cells around the hair follicles, helping them repair. About 1-2 weeks after treatment, hair follicles start to enter the growth phase (anagen) and the regrowth process begins. Visible improvements typically start to appear between 4 to 6 months, with the best results becoming clear after 6 to 12 months.

 

How PRP is Delivered to Your Scalp

PRP therapy is a straightforward process. It begins with drawing a small sample of blood from you. This blood is then put into a machine called a centrifuge, which separates the platelet-rich plasma (PRP). Once the PRP is ready, your scalp is cleaned, and a numbing cream may be applied to make you more comfortable. The PRP is injected into the areas of your scalp where you’re experiencing hair thinning. Multiple small injections are given to make sure the PRP is spread evenly across the targeted areas.

 

Types of Hair Loss PRP Treats

Research shows that PRP therapy can be effective for various types of hair loss:

• Androgenic Alopecia: PRP helps counteract the effects of DHT, promoting hair regrowth in the early stages of male and female pattern baldness.
• Alopecia Areata: PRP promotes anti-inflammatory effects, encouraging hair to regrow in areas affected by autoimmune hair loss.
• Telogen Effluvium: PRP stimulates dormant hair follicles, helping to restore normal hair growth patterns.
• Traction and Scarring Alopecia: PRP reduces inflammation and may help protect the remaining hair follicles.

 

 When to Expect Results?

Hair regrowth from PRP therapy happens gradually, following your body’s natural healing and hair growth processes. Here’s what to expect:

• 1–3 Months: You might notice some initial shedding. This is normal because PRP activates dormant hair follicles, causing weaker hairs to fall out as new, healthier ones begin to grow. This shedding shows that the treatment is starting to work.
• 4–6 Months: During this time, you’ll likely see visible improvements in hair thickness and fullness. The PRP stimulates follicle activity, leading to stronger and healthier new hair. The increased blood flow and nutrients from PRP help rejuvenate the scalp, promoting better hair growth.
• 6–12 Months: The full results usually appear within 6 to 12 months. Your hair will look fuller, thicker, and stronger as the follicles repair and rebuild. Consistent PRP treatments can help maintain and enhance these results for longer-lasting improvements in hair quality.

 

 How Many PRP Treatments Are Needed?

The number of PRP treatments needed varies based on the type and severity of hair loss:

• Mild Hair Loss: For early-stage thinning or minimal shedding, 3-4 PRP sessions are usually enough. These are typically done every 4-6 weeks. After this initial series, you might need maintenance treatments every 6-12 months. This plan works well for early androgenetic alopecia or stress-related shedding, especially in younger individuals.
• Moderate Hair Loss: If you have visible thinning or a receding hairline, you may need 4-6 PRP sessions, also spaced 4-6 weeks apart. Maintenance sessions every 4-6 months are recommended afterward. This approach is suitable for moderate androgenetic alopecia, postpartum hair loss, or mild hormonal issues like PCOS, especially in people in their 30s to 40s.
• Severe Hair Loss: For severe hair loss, such as bald spots or advanced thinning, a more intensive plan is needed. This generally includes 6 or more PRP sessions, with treatments every 4 weeks, and ongoing maintenance every 3-4 months. This is often required for advanced conditions or significant hormonal imbalances, especially in older patients.
• Hormonal Imbalance: For hair loss due to hormonal issues like PCOS or thyroid problems, 4-6 PRP sessions are usually recommended, spaced 4-6 weeks apart, with maintenance every 4-6 months. Hormonal imbalances may need additional treatments or therapies to manage effectively.
• Post-Menopausal Hair Loss: Women experiencing hair loss after menopause might need 5-6 initial PRP sessions, with maintenance every 3-4 months. Combining PRP with other treatments, like minoxidil or hormone replacement therapy (HRT), can improve results.

 

PRP and Scalp Vitamin Treatments

Combining PRP therapy with scalp vitamin treatments, known as mesotherapy, can significantly enhance the results of hair restoration. Vitamins like biotin (Vitamin B7) strengthen hair follicles, while B-complex vitamins improve blood circulation and support healthy hair growth. Vitamin C and zinc offer antioxidant benefits, protecting hair follicles from oxidative damage and supporting overall scalp health. The synergistic effect of combining PRP with these vitamins provides a comprehensive approach to treating hair loss. Mesotherapy involves injecting a blend of vitamins and nutrients directly into the scalp, which can further stimulate hair follicles and improve their health. This combined approach not only promotes hair regrowth but also helps to nourish and revitalize the scalp, creating an optimal environment for hair growth.

In a nutshell, PRP therapy is a natural and scientifically supported method for addressing hair loss. When combined with scalp vitamin treatments, it enhances both hair regrowth and overall scalp health. This combination offers a non-invasive, effective solution for individuals seeking to combat hair thinning and balding, making it an increasingly popular choice among those looking for comprehensive hair restoration options.
