Stem cell hair treatment injects mesenchymal stem cells, isolated from a small sample of your own fat and expanded in the laboratory, into the thinning areas of the scalp, where the growth factors they release help weakened follicles return to the growth phase and produce stronger hair. It suits men and women with early or moderate hair loss whose follicles are still alive, such as androgenetic alopecia, diffuse thinning and telogen effluvium, and it is not a hair transplant.
At Bioscience Institute this protocol is called HAIRSKILL. It is one of our stem cell therapies and relies on the GMP cell laboratories the institute has run since 2007. This page explains how stem cell therapy for hair works, who it helps, each step of the procedure, the before and after timeline, side effects, cost factors and how it compares with PRP, exosomes and FUE transplants.

What is stem cell hair treatment?
Stem cell hair treatment is a regenerative medical procedure that uses your own adipose-derived stem cells (ADSC) to counter follicle miniaturisation and hair loss. The cells come from your own body, so no artificial component is injected into the skin.
In HAIRSKILL, a small fat sample is collected during an outpatient session, the stem cells are extracted and expanded in our laboratories, and they are then injected into the microenvironment around the hair bulb. Part of the cells produced are frozen, so later sessions do not need a new fat harvest.
The aim is not to create hair where none is left. The aim is to wake up and strengthen follicles that are weakened, miniaturised or resting, and to slow further loss. This is why stem cell hair restoration works better when it starts early, while the follicles are still there to respond.
How does stem cell therapy for hair work?
Stem cell therapy for hair works through signalling: the injected cells release growth factors and cytokines that prolong the anagen (growth) phase of the hair cycle and improve the environment in which the follicle lives. The cells do not turn into hair themselves; they help the follicle recover its function.
Why hair follicles weaken
Hair thinning begins at the cellular level, long before it is visible in the mirror. Over time the follicle's own stem cells lose their regenerative capacity, blood flow to the scalp declines, inflammatory signals increase and oxidative stress damages the parts of the cell that produce energy.
The follicle shrinks (miniaturisation), the growth phase becomes shorter and each new hair grows back thinner. In androgenetic alopecia this process is driven by genetics and hormones; in telogen effluvium by stress, illness or hormonal change; in alopecia areata by the immune system attacking the follicle.
What the stem cells do on the scalp
- Wake up dormant follicles: growth factors signal resting or miniaturised follicles to re-enter the growth phase.
- Improve blood supply: mesenchymal stem cells promote the formation of new small vessels (angiogenesis), bringing more oxygen and nutrients to the bulb.
- Calm inflammation: their anti-inflammatory action protects follicles from further damage.
- Rebalance immune activity: useful when hair loss has an autoimmune component, as in early alopecia areata.
- Support the follicle niche: a healthier scalp environment helps follicular tissue repair itself and sustain growth.
Why adipose-derived stem cells
Fat tissue is a practical source of mesenchymal stem cells. A small sample taken in an outpatient setting is enough for the laboratory to obtain and expand a standardised cell population. Because the cells are autologous (your own), no donor material is involved.
Expanded cells, not same-day fat
Many clinics offer "stem cell" procedures based on stromal vascular fraction (SVF), a mixed group of cells extracted from fat and reinjected in the same session. SVF contains some stem cells together with many other cell types, which makes results variable. HAIRSKILL uses mesenchymal stem cells that are isolated and expanded in a controlled laboratory over at least two weeks, for a purer and standardised cell population.
For the same reason, be careful with treatments that claim to use "stem cells from blood". The stem cells used to treat blood diseases come from the bone marrow, and PRP prepared from a blood sample contains platelets and their growth factors, not stem cells.
Who is stem cell hair treatment for?
Stem cell hair treatment is for people whose follicles are weakened but still alive, because it works only if the hair bulb is not irreversibly compromised. It is often chosen by younger patients and by people in the early phase of hair loss who are not yet candidates for a transplant, or who want to act before surgery becomes the only option.
Men
Men with early or moderate male pattern hair loss (androgenetic alopecia), where follicles are still present but miniaturised, and with diffuse thinning rather than completely bald areas. It is also considered by men who responded poorly to conventional hair loss treatment.
Women
Women with diffuse thinning on the crown or a widening part line, female pattern hair loss, hair loss triggered by stress and thinning after pregnancy. Women often respond well because they tend to seek treatment earlier and their hair loss is usually diffuse rather than complete.
Other forms of hair loss
- Telogen effluvium: shedding after stress, illness or hormonal change. It can improve on its own; stem cells aim to speed up recovery and restore healthy hair cycles.
- Early alopecia areata: the anti-inflammatory and immune-modulating action of the cells supports regrowth in patchy hair loss.
- Traction alopecia: hair loss from tight hairstyles, if the follicles are still alive.
- Early scarring alopecia: treated early, the cells help reduce inflammation and protect the remaining follicles.
Who it does not suit
Stem cells cannot regrow hair in long-standing bald areas where the follicles are gone. There a transplant remains the surgical option, and stem cell therapy can still help preserve the existing hair around it.
The treatment is postponed in case of active infections or uncontrolled medical conditions. Every case starts with a medical assessment of the scalp, the stage of hair loss and general health.
The HAIRSKILL procedure step by step
The HAIRSKILL regenerative technique is based on mesenchymal stem cells obtained from your own adipose tissue, in four steps: a small fat harvest, extraction and expansion of the cells in the laboratory, injection into the scalp and freezing of the remaining cells. The whole process is outpatient and simple.
1. Consultation and scalp assessment
A doctor examines the scalp, the pattern and stage of hair loss, your medical history and the treatments you have already tried. The aim is to confirm that the follicles are still viable and that stem cell hair treatment is the right option, alone or together with other therapies.
2. Fat harvest (20 cc)
About 20 cc of fat is collected during a short outpatient session with local anaesthesia. The site of the harvest is chosen at the consultation, and patients describe this step as quick and painless.
3. Extraction and expansion in the laboratory
Bioscience Institute laboratories extract the stem cells from the fat and expand them in about three to four weeks. The laboratory produces about ten vials of cells: some are used for the treatment, the rest are cryopreserved.
4. Scalp injections
The expanded cells are injected with a very fine needle into the thinning areas, close to the hair bulbs, and local anaesthesia keeps the session comfortable. Once in place, the cells release specific growth factors and promote tissue regeneration.
5. Freezing and storage
The remaining vials are frozen and cryopreserved for three years. They stay available for new sessions or future treatments without another fat harvest.
Anaesthesia, duration and downtime
Both the harvest and the injections are outpatient procedures, so you go home the same day. Most people return to their normal routine quickly; the doctor gives simple aftercare instructions for the harvest site and the scalp.
From the first visit to the first injection it takes about one month, because of the laboratory phase. After that, sessions with your stored cells can be planned without waiting.
Stem cell hair treatment before and after: what results to expect
The first results of stem cell hair treatment are visible after about a month and increase gradually, with improvement continuing for up to 9 to 12 months. Results build in steps, following the natural rhythm of the hair cycle.
Month 1
The first change is usually less shedding and a calmer, healthier scalp. Growth factors are acting on the follicles, but the new growth is not yet long enough to change how the hair looks.
Month 3
Progressive thickening becomes visible from the third month onward. Miniaturised hairs start to grow back with a stronger shaft, especially in diffuse thinning.
Month 6
Density and texture keep improving as more follicles complete a full growth phase. This is a good moment for the doctor to compare photographs with the starting point and decide whether a further session is useful.
Month 12
Improvement continues up to 9 to 12 months. At one year the result is assessed and a maintenance plan is agreed, often with your cryopreserved cells.
What results can include
- Slowing or stopping the progression of hair loss, especially in early or moderate stages.
- Thicker and stronger hair shafts in thinning areas.
- Regrowth of miniaturised hair where follicles are still present.
- A healthier scalp, with less inflammation and better blood flow.
- Less shedding and better hair texture.
The effectiveness of the treatment is affected by genetics, skin conditions, age, lifestyle, the type and stage of hair loss and consistency with follow-up. For these reasons it varies from person to person.
Maintenance
Androgenetic alopecia is a progressive condition, so the benefit is kept with follow-up. A maintenance session is often repeated every 6 to 12 months, using the vials already in storage.
How many sessions of stem cell hair treatment do you need?
Most people start with one treatment from a single fat harvest, and the doctor may recommend further sessions to complete the result, plus maintenance every 6 to 12 months. The exact number depends on your hair loss and on how your scalp responds.
The main factors are:
- the type and stage of hair loss;
- the size of the area to treat;
- the response seen at the three-month and six-month checks;
- whether the plan combines stem cells with exosomes or medical therapy.
Because the laboratory produces about ten vials from one 20 cc sample, the cells for follow-up sessions are already in storage. This is a practical difference from PRP, which needs a new blood draw each time, and from same-day fat procedures, which repeat the harvest.
Side effects and risks of stem cell hair treatment
Side effects of stem cell hair treatment are usually mild and local: temporary redness, swelling or tenderness of the scalp after the injections, and a small bruise or soreness where the fat was taken. These effects settle on their own within a few days.
Because the cells are your own, there is no foreign material and no donor cells to reject. The key safety factors are cell processing in a GMP laboratory under controlled conditions and correct medical technique.
As with any injection or minor procedure, there is a small risk of infection, which sterile technique keeps low. Tell the doctor about any medicines that affect bleeding and about skin conditions on the scalp before treatment.
When the treatment is postponed or not advised
- Active infections, including infections of the scalp.
- Uncontrolled medical conditions.
- Pregnancy and breastfeeding, when elective treatments are usually postponed.
- Areas where the follicles are irreversibly lost, where the treatment cannot regrow hair.
How much does stem cell hair treatment cost?
The cost of stem cell hair treatment depends mainly on the laboratory work (isolating and expanding your own cells), the number of injection sessions and the storage of the remaining vials. A personal quote follows the medical assessment, because the area to treat and the plan differ from one person to another.
What drives the price
- The medical consultation and the fat harvest.
- Laboratory isolation and expansion: three to four weeks of GMP work on your cells.
- The number of sessions and the size of the area treated.
- Cryopreservation of the remaining vials for three years.
- Combined treatments, such as exosomes or medical therapy.
- Follow-up visits and maintenance sessions.
Lower prices often reflect same-day fat or SVF procedures that skip the laboratory phase, so compare what is actually injected, not only the figure. For price ranges and how to read a quote, see our guide to stem cell therapy cost and our checklist on how to choose a stem cell clinic.
Stem cells vs PRP vs exosomes vs hair transplant
Stem cells, PRP, exosomes and FUE hair transplants act on hair loss in different ways: the first three are scalp injections that strengthen existing follicles, while a transplant surgically moves follicles into areas where they are gone. The right choice depends on how many living follicles you still have.
| Stem cells (HAIRSKILL) | PRP | Exosomes (EXOHAIR) | FUE hair transplant | |
|---|---|---|---|---|
| What is used | Your own adipose-derived mesenchymal stem cells, expanded in the laboratory | Platelet concentrate from your own blood | Cell-free vesicles released by mesenchymal stem cells | Your own follicles, moved from a donor area |
| Preparation | 20 cc fat harvest, then 3 to 4 weeks of laboratory expansion | Blood draw, prepared the same day | No harvest; ready in 2 to 3 days from the biobank | Surgical procedure |
| Living stem cells | Yes | No | No | No |
| Main action | Growth factors, longer growth phase, better blood supply, less inflammation | Platelet growth factors | Signalling molecules that activate follicles, support blood vessels and modulate immunity | Adds follicles where they are lost |
| Suited to | Early to moderate thinning with viable follicles | Weakened follicles | Weakened follicles, inflammation-driven hair loss | Bald areas with no living follicles |
| Follow-up sessions | From frozen vials, no new harvest | New blood draw each time | Ready-made product | Further surgery if needed |
For a closer look at each option, read stem cells vs PRP, exosomes vs PRP and our guide to exosome treatment for hair loss.
Stem cells or exosomes for hair?
Exosomes are the messengers that stem cells release. They need no fat harvest and are ready within days, which helps when you want to start quickly or when inflammation drives the hair loss. Stem cells add a living source of these signals and a personal cell reserve for future sessions. Our page on exosomes vs stem cells compares them in detail.
Is stem cell hair treatment a hair transplant?
No: stem cell hair treatment does not move or implant follicles, it injects cells that strengthen the follicles you already have. The phrase "stem cell hair transplant" is common online, but in medicine a hair transplant (FUE or FUT) is surgery that relocates follicles from a donor area.
The two can work together. Treatment with adipose stem cells makes hair transplants easier, because it strengthens and prepares the scalp before surgery and stimulates engraftment of the grafts in the bulb. For people still in the early stage, it is a way to act before a transplant becomes the only way forward.

FAQ
Does stem cell hair treatment work?
It is effective mainly on weakened but living follicles: the stem cells release growth factors that prolong the growth phase, improve blood supply and reduce inflammation, so shedding slows and miniaturised hair can thicken. Results vary with genetics, age, lifestyle and the stage of hair loss, which is why a medical assessment comes first.
Is stem cell hair treatment permanent?
Strengthened hair lasts as long as its follicle stays healthy, but androgenetic alopecia keeps progressing. For this reason a maintenance session every 6 to 12 months is often advised, using your cryopreserved cells.
Is the treatment painful?
The fat harvest and the scalp injections are outpatient procedures done with local anaesthesia, and patients describe them as quick and well tolerated. Mild tenderness or redness can last a few days.
How soon will I see results?
The first results are visible after about a month, usually as less shedding. Thickening becomes clearer from the third month and improvement continues for up to 9 to 12 months.
Does stem cell hair treatment work for women?
Yes. Women with diffuse thinning, a widening part, stress-related hair loss or thinning after pregnancy often respond well, partly because they tend to start treatment earlier while the follicles are still present.
Can I combine stem cell hair treatment with minoxidil or finasteride?
Yes, it can be part of a combined plan: results are better when stem cell therapy is combined with lifestyle changes and, when appropriate, other medical treatments. Your doctor decides which medicines to keep or adjust.
Is stem cell hair treatment a hair transplant?
No. It injects your own stem cells to strengthen existing follicles, while a transplant moves follicles surgically. It can also prepare the scalp before a transplant and support the grafts.
Can stem cells regrow hair on a completely bald area?
No. Stem cells reactivate follicles that are weakened or dormant, but they do not create new follicles where none are left. In long-standing bald areas a transplant is the option, and stem cells can help preserve the hair around it.
How much does stem cell hair treatment cost?
The price depends on the laboratory expansion of your cells, the number of sessions, the area treated and the storage of the remaining vials, so a personal quote follows the medical assessment. Our stem cell therapy cost guide explains the factors and how to compare quotes.
Do I need a new fat harvest for every session?
No. One 20 cc fat sample gives about ten vials of cells; those not used right away are cryopreserved for three years and used for later sessions without another harvest.
