Yes, PRP may help support hair regrowth and improve hair density in some people, particularly those experiencing certain types of hair loss such as pattern hair loss. PRP, or platelet-rich plasma, uses a concentrated preparation of your own blood platelets, which is injected into the scalp with the aim of supporting the hair follicles and encouraging healthier hair growth. However, results vary from person to person, and PRP is not a guaranteed solution for hair loss.
What Is PRP for Hair Regrowth?
PRP stands for platelet-rich plasma. It is prepared using a small sample of your own blood, which is processed to concentrate the platelets.
Platelets contain growth factors and other substances involved in tissue repair and regeneration. When PRP is injected into areas of the scalp where the hair is thinning, these growth factors may help support the environment around the hair follicles.
PRP has therefore become an area of interest for people looking for treatment options for hair thinning and hair loss.
How Does PRP Help With Hair Regrowth?
The exact way PRP supports hair growth is still being researched.
The growth factors found in platelets may influence the activity of hair follicles and the growth cycle of the hair. PRP treatment aims to support follicles that are still present but may be producing thinner or weaker hair.
This is important because PRP is not designed to create completely new hair follicles. Instead, the treatment is intended to support existing follicles and potentially improve the density and quality of growing hair.
Research has found promising results for PRP in people with androgenetic alopecia, also known as male or female pattern hair loss, although studies have used different preparation methods and treatment protocols.
Can PRP Actually Regrow Hair?
PRP may help with hair regrowth, but it is important to have realistic expectations.
Some studies have reported an increase in hair density following PRP treatment. However, the response is not identical for everyone.
The outcome can depend on factors such as:
- The underlying cause of hair loss
- How advanced the hair loss is
- The condition of the existing hair follicles
- Individual response to treatment
- The PRP preparation and treatment protocol used
PRP is therefore better viewed as a treatment that may support existing hair follicles and improve hair density, rather than a guaranteed way to restore all lost hair.
Does PRP Work for Thinning Hair?
PRP may be particularly relevant when hair follicles are still present but hair has become progressively thinner.
For example, people with pattern hair loss may notice:
- A widening parting
- Thinner hair around the crown
- Receding hairline
- Reduced overall hair density
- Finer individual hairs
In these situations, PRP may be considered as one potential treatment option.
However, thinning hair can have many different causes. Identifying the underlying cause is important before deciding whether PRP is appropriate.
What Types of Hair Loss Can PRP Treat?
PRP has been studied most extensively in relation to androgenetic alopecia, or pattern hair loss.
Hair loss can also occur because of other factors, including hormonal changes, nutritional deficiencies, certain medical conditions, medications, stress and inflammatory or autoimmune conditions.
PRP may not be appropriate for every type or cause of hair loss.
This is why an individual assessment is important before treatment. Understanding why your hair is thinning can help determine which treatment options may be suitable.
How Many PRP Sessions Are Needed for Hair Regrowth?
There is no single number of PRP treatments that applies to everyone.
Different studies have used different numbers of sessions and different intervals between treatments. Your clinician can discuss an appropriate treatment plan based on your individual circumstances and treatment goals.
It is also important to understand that PRP is not an overnight treatment. Hair grows gradually, so any improvement in hair density takes time to become noticeable.
When Will You See Hair Regrowth After PRP?
Hair growth occurs in cycles, so you should not expect immediate regrowth following a PRP treatment.
If you respond to treatment, changes may become noticeable gradually over the following months. The exact timeframe varies between individuals.
Your clinician can explain what you may reasonably expect based on your particular situation.
Can PRP Regrow Completely Lost Hair?
PRP is not generally considered a way to recreate hair follicles that are no longer present.
The treatment is intended to support existing follicles. This means the potential for improvement may be different in an area where hair is thinning compared with an area that has been completely bald for a long period.
This is one reason why early assessment of progressive hair thinning can be useful.
Is PRP Effective for Everyone?
No. PRP does not work in exactly the same way for everyone.
Research into PRP for hair loss has produced encouraging findings, but studies vary considerably in how PRP is prepared, administered and measured. This makes it difficult to predict exactly how an individual person will respond.
A clinician can assess your hair loss and discuss whether PRP is a suitable option for you.
What Happens During PRP Hair Treatment?
PRP treatment begins with taking a small blood sample.
The sample is processed to separate and concentrate the platelet-rich plasma. The resulting PRP is then administered into the areas of the scalp being treated.
The procedure is carried out with the aim of delivering the concentrated platelet preparation to areas where the hair is thinning.
Your clinician will explain the treatment process and what to expect before proceeding.
