Watching your hair become thinner can be frustrating, especially when changing shampoos, oils or supplements does not seem to make much difference.The reason is simple: hair loss is not always a surface-level problem.
For certain types of hair loss, the health and activity of the hair follicle itself need to be considered. This is where GFC hair treatment, or Growth Factor Concentrate therapy, comes in GFC uses growth factors obtained from your own blood and delivers them into targeted areas of the scalp. The aim is to create an environment that supports hair follicles, reduces hair fall and encourages healthier hair growth.
How Does GFC Help Hair Regrowth?
GFC, or Growth Factor Concentrate, is an autologous treatment, meaning it is prepared from your own blood.
Platelets naturally contain growth factors involved in cell signalling, tissue repair and regeneration. During GFC treatment, blood is processed to obtain a concentrated preparation of these growth factors, which is then administered into areas of the scalp affected by hair thinning.
These growth factors may support follicular activity, improve the environment around the hair follicle and promote healthier hair growth.
Clinical research on GFC for androgenetic alopecia has reported improvements in measures such as hair density and hair quality, although research on GFC is still developing.
What Exactly Is GFC Hair Treatment?
GFC stands for Growth Factor Concentrate.
The treatment begins with a small amount of your own blood. This blood is processed using a specialised system designed to activate platelets and obtain a preparation rich in growth factors.
The process generally involves:
- Drawing a small amount of blood
- Processing it to release and concentrate growth factors
- Separating the required growth-factor-rich preparation
- Injecting it into targeted areas of the scalp
Because the preparation originates from your own blood, GFC is considered an autologous treatment.

How Do Growth Factors Help Hair Follicles?
This is where the science becomes interesting.
Hair follicles are living mini-organs that repeatedly move through growth and resting phases. Their activity is influenced by signalling molecules, blood supply, hormones and other biological factors.
Platelets contain several growth factors and signalling proteins. These may include factors such as:
- Platelet-derived growth factor (PDGF)
- Vascular endothelial growth factor (VEGF)
- Epidermal growth factor (EGF)
- Insulin-like growth factor (IGF)
- Other signalling proteins involved in tissue repair
When concentrated growth factors are delivered into the scalp, they are intended to support biological processes around the hair follicle.
A peer-reviewed study on GFC for hair loss reported improvements in hair quality and density following treatment in patients with androgenetic alopecia. However, the study involved only five patients, so its findings should be considered promising rather than definitive.
What Happens After GFC Is Injected Into the Scalp?
GFC does not simply “create new hair” immediately after it is injected.
Instead, the treatment aims to support the biological environment in which existing hair follicles function.
The process can be understood like this:
- Growth factors are prepared from the patient’s blood.
- The concentrate is delivered into areas experiencing hair thinning.
- Growth factors interact with cells and tissues around the follicles.
- Biological signalling involved in tissue repair and follicular activity is supported.
- Over time, suitable follicles may produce healthier or thicker-looking hair.
Because hair grows in cycles, visible changes take time.
Can GFC Increase Hair Density?
This is one of the main reasons people consider GFC hair treatment.
Research has shown encouraging results.
A 2024 study evaluating concentrated growth factors in patients with androgenetic alopecia found significant improvements in hair density and hair growth ratio three months after the first treatment, with improvements maintained during the six-month observation period.
However, GFC research is still relatively limited compared with some established hair-loss treatments. Results can also vary considerably between individuals.
GFC should therefore be viewed as a treatment option that may support hair regrowth in appropriately selected patients rather than a guaranteed cure for every type of hair loss.
Who May Benefit From GFC Hair Treatment?
GFC may be considered for people experiencing concerns such as:
- Early-stage hair thinning
- Pattern hair loss
- Reduced hair density
- Progressive thinning associated with androgenetic alopecia
- Weak or thinning hair in areas where follicles remain active
The key point is that the cause of hair loss matters.
Hair fall can occur because of genetics, nutritional deficiencies, hormonal changes, stress, illness, medications, scalp conditions and several other factors.
If a follicle is permanently lost or extensively scarred, injectable growth-factor treatments cannot simply recreate a completely new follicle.
That is why diagnosing the reason for hair loss should come before deciding on treatment.
Is GFC the Same as PRP?
They are related, but they are not exactly the same.
Both GFC and PRP are prepared from the patient’s own blood and make use of platelet-derived biological components.
PRP typically involves preparing platelet-rich plasma, while GFC techniques are designed to obtain a concentrated preparation of released growth factors.
The exact preparation protocols can vary, so rather than assuming that one treatment is universally “better,” the more important question is which approach is appropriate for your type and stage of hair loss.
How Many GFC Sessions Are Usually Needed?
There is no universal number that works for everyone.
Treatment frequency can depend on:
- Type of hair loss
- Degree of thinning
- Hair density
- Age
- Follicular health
- Underlying medical or hormonal factors
- Response to previous sessions
Welona’s current GFC protocol recommends three initial sessions spaced approximately four to six weeks apart, followed by maintenance treatment when appropriate.
Your actual treatment plan should still be based on your individual hair and scalp assessment.
When Can You Expect to See Hair Regrowth?
Hair growth takes time because follicles follow a natural growth cycle.
You should not expect to walk out after a GFC session with visibly thicker hair.
Changes, when they occur, develop gradually. Depending on the individual, these may include:
- Reduced hair fall
- Improvement in hair density
- Better-looking hair quality
- Increased hair shaft thickness
- Gradual improvement in thinning areas
Clinical studies have observed changes over periods ranging from several weeks to a few months. Your response will depend on the underlying cause and severity of hair loss as well as your individual biology.
Why a Hair and Scalp Assessment Matters ?
Hair loss may look similar from the outside while having completely different causes underneath.
Before recommending GFC, it is important to understand:
- Why your hair is thinning
- Whether follicles are still active
- The pattern and severity of hair loss
- Your scalp condition
- Relevant hormonal or nutritional factors
- Whether GFC should be used alone or alongside other treatments
This makes treatment more targeted rather than simply injecting GFC whenever someone reports hair fall.

Final Thoughts
So, how does GFC help hair regrowth?
It uses concentrated growth factors derived from your own blood to support biological processes around existing hair follicles. For suitable candidates, this may help improve hair density, hair quality and overall follicular activity over time.
But GFC is not a one-treatment-fits-all solution.
The best results begin with identifying why your hair is thinning in the first place and choosing a treatment plan accordingly.

Frequently Asked Questions
1. Does GFC really regrow hair?
GFC may support hair regrowth in suitable patients by delivering concentrated growth factors to areas with active but thinning hair follicles. Clinical studies have reported improvements in hair density and hair quality, particularly in androgenetic alopecia. Results vary, and GFC cannot guarantee regrowth in every case.
2. How long does GFC take to show hair growth?
Hair growth is gradual. Some clinical studies have reported measurable improvements within a few months of treatment. The exact timeline depends on the cause of hair loss, follicular health, treatment schedule and individual response.
3. Is GFC better than PRP for hair loss?
Both treatments use components derived from the patient’s blood, but their preparation differs. Some emerging studies have compared their outcomes, but there is not enough high-quality evidence to say that GFC is universally better than PRP for every patient. Treatment should be selected according to the individual’s hair-loss condition.
4. How many GFC sessions are needed for hair regrowth?
The number of sessions varies according to the type and severity of hair loss. Welona currently recommends three initial GFC sessions spaced around four to six weeks apart, with maintenance treatment considered afterwards based on individual requirements.
