Because appointments requiring an interpreter take additional time for both the consultation and the procedure, a 10% surcharge applies to the fees listed on this page.
What is Micrograft Hair Regrowth Therapy?
- - Your own skin tissue, finely processed, is injected into the scalp
- - Generally a single session per year is sufficient
- - Suitable for both men and women
This treatment addresses thinning hair and scalp ageing by injecting your own skin tissue, finely fragmented using a dedicated device, into the scalp. Treatment effect is generally assessed after a single session per year, and both men and women can receive it.
A skin sample of approximately 3 mm is taken from a healthy hair-bearing area. The dermis and follicular tissue, which contain growth factors, are fragmented to prepare an injectable solution. Injecting this into the areas of concern promotes the formation of new capillaries in the dermis, and hair growth through improved blood flow is anticipated.

Tissue is taken from a healthy hair-bearing area, processed using a dedicated technique, and injected into the scalp.

The skin sample is taken from a hair-bearing area at the back of the neck.

The harvest site immediately after the procedure, and immediately after suture removal (one week later).
Conditions we treat
If there is almost no hair remaining in the treatment area, improvement cannot be expected, and we may advise against the procedure.
Characteristics of this treatment
- - Uses your own cells
- - Some patients notice a change in as little as two weeks
- - Aims to improve overall scalp skin function
- - No additives; low likelihood of allergic reaction
- - An option for those who felt limited benefit from other treatments

The micrograft solution is injected carefully across the whole treatment area.
How it differs from other hair loss treatments
| Micrograft therapy | Oral AGA medication | Hair transplant | HARG therapy | PRP hair therapy | |
|---|---|---|---|---|---|
| Method | Your own skin tissue (dermis and follicles) is harvested, processed and injected | Oral medication to slow the progression of hair loss | Follicles from the back of the head are transplanted to thinning areas | Stem cell culture supernatant is injected into the scalp | Platelets (growth factors) concentrated from your own blood are injected |
| Sessions | Generally one session (approx. once a year) | Ongoing daily use required | Generally one session (more if the area is large) | Repeated sessions required | Several sessions, roughly once every three months |
| Time to notice change | From two weeks in some patients; around 3–6 months | Around 3–6 months | Around 6 months to 1 year | Varies considerably between individuals | Varies; more noticeable with continued sessions |
| Downtime | Mild swelling at the harvest and injection sites (a few days to one week) | None | Scarring and swelling at the donor site (1–2 weeks) | Minimal | Mild swelling or bruising at injection sites (a few days) |
| Mainly suited to | AGA, FAGA, early-onset and age-related thinning | AGA (androgen-related hair loss) | Advanced hair loss, receding hairline | A wide range of thinning conditions | Prevention and slowing of thinning |
PRP hair therapy may also be combined with micrograft therapy, from one week after the procedure.

Local anaesthetic is applied to the area from which the skin sample will be taken.
A skin sample of approximately 3 mm is taken from a hair-bearing area at the back of the neck, and the site is sutured.
The tissue is processed and the micrograft solution is prepared.
The micrograft solution is injected across the treatment area of the scalp.
Sutures at the harvest site are removed one week after the procedure.

All cases shown were treated at the monitor fee of 330,000 yen per session (tax included).
Main risks and side effects: temporary swelling and bruising at the harvest and injection sites (usually resolving within a few days to one week). Results vary between individuals.
The fragmentation device "Rigenera" is not approved in Japan (obtained via a domestic distributor; no equivalent approved device exists in Japan; CE marked in the EU and FDA cleared in the United States).
