How to get rid of bald spots with platelet-rich plasma (PRP) injections starts with one key idea: if hair follicles are still alive, they can often be reactivated. PRP (platelet-rich plasma) injections use a person's own blood components to stimulate hair follicles, promote hair growth, and gradually fill in bald spots and thinning areas.
For many men and women with androgenetic alopecia or patchy hair loss, PRP can reduce shedding within a few months, increase hair density by around 30–40%, and lead to visibly fuller hair over 6–12 months. It's especially effective when bald spots still contain a few hairs and the follicles are weakened, not destroyed. Treatment involves a series of injections, not a one-time quick fix, but a structured plan that targets the affected area specifically.
For many people wondering how to get rid of bald spots in the head, PRP injections can reduce shedding and boost hair density.
PRP injections work by concentrating platelets from your own blood and injecting them into thinning areas to deliver growth factors.
The best candidates for PRP for bald spots have early to moderate androgenetic alopecia or mild patchy hair loss, and understand that results are gradual, not instant.
A typical PRP treatment plan involves 3–6 initial sessions spaced 4–6 weeks apart, with maintenance every 3–6 months to sustain fuller coverage and slow ongoing hair loss.
PRP for bald spots is generally safe with mild, temporary side effects like tenderness or swelling.
If PRP is not suitable or bald spots are fully smooth and long‑standing, alternatives such as minoxidil, hair transplant surgery, hairstyles, wigs, or embracing a shaved look may offer better or more practical results.
Bald spots can come from several different causes, and PRP injections only help when living hair follicles remain in the skin. Understanding the cause is the first step before any treatment options are chosen.
Most people asking how to get rid of bald spots are dealing with androgenetic alopecia, also called hereditary hair loss or pattern baldness. In this condition, hormones and family history gradually shrink hair follicles, leading to thinning hair on the crown or receding hairlines.
In early hair loss stages, there are still patches of hair and some hair density left, even if the scalp shows through. These weakened follicles can often respond to PRP, which promotes hair regrowth and helps existing hair grow thicker and stronger. When the scalp is completely smooth and shiny, follicles may be gone, and PRP is less likely to help.
Another common cause of bald patches is alopecia areata, an autoimmune disease where the immune system attacks hair follicles. People suddenly lose hair in round or oval patches of hair on the scalp or body. Some individuals with mild or moderate patchy hair loss from alopecia areata may see benefit, especially if other medications are used alongside PRP under specialist supervision.
Bald spots can also follow physical trauma, scarring skin conditions, severe scalp irritation, chemical burns, or tight styling techniques that damage follicles. When scar tissue replaces normal skin, hair follicles may be permanently destroyed. In those cases, hair transplant surgery is usually more appropriate than PRP.
PRP works best for men and women with early to moderate thinning hair rather than completely bare, long‑standing bald patches. If there are still a few hairs in the affected area and the scalp shows miniaturized, fine hair, PRP has something to work with.
A healthcare provider will typically start with a physical exam of the scalp and a detailed history of hair loss, family history, medications, and styling products used. They may also order a blood test to check overall health, hormone issues, vitamin levels, and platelet counts, because low platelets can reduce PRP effectiveness.
Good candidates usually:
Have androgenetic alopecia or mild patchy hair loss.
Still have visible hair follicles and some hair density.
Are willing to attend several sessions over a few months.
Understand that results vary and there are possible side effects.
People are usually not ideal candidates if they have extensive shiny baldness, active scalp infections, uncontrolled autoimmune diseases, blood clotting disorders, or very low platelet counts. Individuals taking certain medications that affect platelets may also need clearance from their doctors.
Someone looking for an instant, one‑session permanent solution is also likely to be disappointed. PRP is a gradual process that supports new hair growth and slows further hair loss, rather than a quick cosmetic cover‑up like a wig or buzz cut.
PRP injections concentrate platelets from a person's own blood and deliver them directly into thinning areas of the scalp, where they can influence hair follicles and the surrounding skin environment.
Platelets are tiny blood cells best known for helping blood clot after injury. They also carry growth factors, which are proteins used to treat damaged tissues in several medical fields. In PRP, clinicians separate platelets from whole blood and concentrate them for therapeutic use.
During preparation, a small sample of blood is drawn and spun in a centrifuge. This separates the red blood cells from plasma that contains platelets. The platelet‑rich portion is then extracted for injection. Because PRP is autologous, the risk of allergic reaction is very low compared with many other treatments.
These concentrated platelets release growth factors once injected into the scalp. Those proteins signal surrounding cells, support microcirculation, and help create conditions that promote hair growth.
Hair follicles cycle through growth and resting phases. In hereditary baldness, follicles spend shorter periods in active growth and produce thinner strands of hair. Over time, patches of hair become wispy, and the scalp becomes visible.
PRP appears to help by encouraging follicles to stay in the growth phase longer and by improving the health of the follicle environment. Growth factors may enhance blood supply around follicles and support the cells that actually make hair. When that happens, hair can regrow thicker and stronger.
In practical terms, people often first notice reduced shedding within one to two months. Next, they see subtle new hair growth in thinning areas around three to four months after starting a PRP hair transplant procedure series. By six months, many notice better coverage, improved hair color richness, and more styling options.
PRP will not create entirely new follicles where none exist. If bald spots are completely smooth and have lacked hair for many years, PRP is less likely to produce visible new hair growth. In those situations, hair transplant surgery, a shaved bald look, or a new hairstyle that blends thinning areas may be more realistic choices.
Anyone considering PRP for bald spots needs clear expectations about how well it works, how long results last, and what else might help if it is not suitable.
Clinical research suggests that, in appropriately selected patients, PRP can slow further hair loss, increase hair density, and improve overall hair quality. Many notice less shedding within the first couple of months.
Results are not permanent without maintenance. Because androgenetic alopecia and some autoimmune processes continue, many providers recommend repeat treatments every three to six months. With periodic sessions, improvements can be sustained for years.
PRP is only one way to approach how to get rid of bald spots, and it is not ideal for every person or every cause of hair loss. Fortunately, there are several alternatives.
Topical minoxidil, often recognized under the brand name Rogaine, is widely used to treat androgenetic alopecia. It is applied topically to the scalp once or twice daily and can help some people regrow hair or slow thinning. But, it requires ongoing, consistent use and has possible side effects like dryness or irritation.
For individuals with advanced baldness or long‑standing smooth patches, hair transplant surgery may offer better cosmetic improvement. Transplantation redistributes healthy body hair from dense areas on the head to bald spots, creating lasting coverage when performed by skilled surgeons.
Other treatments include certain oral medications prescribed by physicians, especially for hereditary hair loss, though these carry systemic possible side effects and need careful monitoring. In autoimmune conditions such as alopecia areata, targeted immune‑modulating medications may be necessary.
Some people prefer non‑medical approaches. A new hairstyle, strategic hair products that add volume, or a well‑chosen wig can dramatically change appearance without injections or medications. For others, embracing a clean shave or bald look provides confidence with minimal ongoing effort.
The best plan is individualized, blending medical treatments, self care, and styling techniques according to each person's goals, health, and degree of hair loss.
PRP injections use your own platelet-rich plasma to deliver growth factors directly into thinning areas of the scalp. These signals help weakened hair follicles stay longer in the growth phase, improve blood supply, and thicken existing hairs, which can gradually make bald spots look fuller over 6–12 months if follicles are still alive.
You’re most likely a good PRP candidate if you have early to moderate thinning, androgenetic alopecia, or mild patchy hair loss and still see some hairs in the bald spot. People with completely smooth, shiny, long‑standing bald patches, severe scarring, active infections, or very low platelets are less suitable.
Most treatments involve three to six PRP sessions spaced four to six weeks apart, followed by maintenance every 3-6 months. Many people first notice less shedding within one to two months, early regrowth by three to four months, and visibly fuller coverage of bald spots around six to twelve months.
PRP pricing in Fresno, CA is around $1,000 to $2,000, it varies by how large an area needs treatment. Because it’s considered cosmetic, most insurance plans do not cover PRP for bald spots. Patients typically pay out of pocket and should request a written estimate in advance.
For many individuals struggling with thinning hair and small bald patches, PRP injections offer a targeted, research‑supported way to promote hair growth and improve hair density. Results come gradually over a few months, not overnight, and depend heavily on whether hair follicles remain alive.
A thorough evaluation with a qualified healthcare provider is essential to confirm the cause of hair loss, rule out underlying disease, and decide the approach makes the most sense. With realistic expectations and a clear plan, people can move from worrying about bald spots to taking confident, informed steps toward the appearance they want.
