Not everyone needs long-term medication after a hair transplant. Short-term medicines, such as the local anaesthetic, painkillers and sometimes an antibiotic or a steroid for swelling, are chosen by your surgeon. Longer-term treatments such as minoxidil or finasteride aim to slow further loss of your existing hair. They only work while they are used and can have side effects, so whether you need one is for your doctor to decide.
This article is for general information only. It does not replace advice from your doctor or pharmacist. Never start, stop or change a medicine without talking to the doctor who prescribed it.
Do You Need Medication After a Hair Transplant?
A hair transplant is usually carried out under local anaesthetic and sedation. What happens afterwards depends on your procedure, your health and your surgeon’s approach.
It helps to separate two questions:
- Which medicines help you through the procedure and the first days? These are short courses that your surgeon prescribes.
- Is long-term treatment for hair loss right for you? The NHS notes that your hair might continue to thin around the transplant. Medical treatment is aimed at that ongoing loss, and whether you need it is a separate decision for your doctor.
Medicines Used Around the Procedure
Details vary between clinics. Your surgeon will tell you exactly what to take, when and for how long.
Local anaesthetic
A local anaesthetic, such as lidocaine, is injected to numb the scalp. Like any medicine, it can cause reactions: the NHS lists an allergic reaction to the anaesthetic among the small risks of a hair transplant. A 2021 review of hair transplant complications describes allergic reactions to local anaesthetics as extremely rare. Your team will ask about allergies and your other medicines beforehand.
Painkillers
Aching, tightness or throbbing after surgery can usually be controlled with pain medication prescribed by your doctor. The International Society of Hair Restoration Surgery (ISHRS) notes that aspirin affects blood clotting. It adds that anti-inflammatory painkillers such as ibuprofen and naproxen may also increase bleeding risk, at higher doses or with frequent use. Ask which painkiller is suitable for you. For more, read our guide to anaesthesia and pain management.
Antibiotics
Some surgeons prescribe antibiotics around the procedure, and practice differs between clinics. Antibiotics are among the medicines that can cause allergic reactions during this period, so tell your team about any antibiotic allergy. If you are prescribed a course, take it exactly as directed.
Steroids for swelling
A 2026 review of FUE complications describes swelling of the forehead and around the eyes in the first days after surgery. Some surgeons use a steroid to limit it, given by mouth, by injection or mixed into the anaesthetic solution. If you are given one, follow the prescription exactly.
Medicines for itching
Itching is common while the scalp heals, and, for itching that persists, the same review lists oral antihistamines among the options. Take one only if your clinic recommends it.
Medicines and Supplements to Tell Your Surgeon About
Some medicines and supplements can increase bleeding during and after surgery. The ISHRS asks patients to tell their doctor about everything they take, whether prescribed, bought over the counter or taken as a supplement. This includes:
- Blood thinners such as warfarin or clopidogrel
- Aspirin, including a daily low-strength aspirin
- Anti-inflammatory painkillers such as ibuprofen and naproxen
- Herbal products such as garlic, ginger, ginkgo, ginseng, saw palmetto, danshen, feverfew and flaxseed
- Vitamin E supplements
Do not stop a prescribed medicine on your own. Blood thinners and aspirin are prescribed for important reasons. According to the ISHRS, the hair restoration surgeon decides whether surgery goes ahead, and may call the doctor who prescribed the medicine. Alcohol affects bleeding too; our guide to smoking and alcohol around a hair transplant explains how.
Minoxidil and Finasteride After a Hair Transplant
The NHS describes finasteride and minoxidil as the main treatments for male pattern baldness. They do not work for everyone.
Minoxidil
Minoxidil is a medicine applied to the scalp. According to MedlinePlus, it needs to be used for at least four months, and possibly up to a year, before any effect is seen. Most new hair is lost within a few months of stopping.
Evidence specific to transplants is limited. In 2001, a group of 11 international experts on hair loss and hair transplantation met to review minoxidil alongside surgery. Their 2002 report was based on the surgeons’ clinical experience. It concluded that approved regrowth medicines may speed regrowth in transplanted follicles and slow further loss. This applied to people whose follicles in the treated area are weakened but still working. This is expert opinion, not trial evidence. The 2021 review also notes that minoxidil speeds up regrowth after shedding in the donor area. Medicine does not skip the normal growth cycle of transplanted hair.
Minoxidil should not be applied to a sunburned or irritated scalp. A current US product label also says not to use it if your scalp is red, inflamed, infected, irritated or painful. Your surgeon will tell you whether, and when, it can be applied to the treated area.
Finasteride
Finasteride is a prescription tablet for male pattern hair loss. It works by blocking the body’s production of a male hormone in the scalp.
- Who it is for: finasteride is only for use in men. The NHS states that women should not use it.
- How long it takes: it may take at least three months to see any improvement. If there is no improvement after 12 months, further treatment probably will not help.
- If you stop: you will probably lose the hair that grew back during treatment within about 12 months.
Whether to pause finasteride around surgery is decided by your surgeon together with the doctor who prescribed it.
Is long-term treatment necessary for everyone?
No. Some people have little ongoing hair loss, and some cannot use these medicines. Before recommending anything, your doctor will weigh your pattern of hair loss, your age and your health.
Medicines at a Glance
This table summarises what each medicine is for and who decides. Doses are left out on purpose: your doctor sets them, and they are printed on your own prescription.
| Medicine | Group | Why it may be used | Who decides | Key safety point |
|---|---|---|---|---|
| Local anaesthetic (e.g. lidocaine) | Day of surgery | Numbs the scalp | Surgeon | Allergy is rare but possible |
| Painkillers | First days | Aching and tightness | Surgeon | Aspirin and some anti-inflammatories may increase bleeding |
| Antibiotics | Around surgery, at some clinics | Infection prevention | Surgeon | Tell your team about any allergy |
| Steroids | First days, at some clinics | Swelling | Surgeon | Follow the prescription exactly |
| Minoxidil | Long term, optional | Ongoing hair loss; may speed regrowth (expert opinion) | Your doctor | Effects stop when it is stopped |
| Finasteride | Long term, optional, men only | Male pattern hair loss | Prescribing doctor | Mood and sexual side effect warnings |
Side Effects and Safety Warnings
Finasteride. In May 2026, the UK medicines regulator (MHRA) strengthened its warnings for the finasteride tablets used for male pattern hair loss:
- If you have depression or suicidal thoughts while taking finasteride, stop treatment and seek medical advice.
- Discuss any concerns about sexual side effects with a healthcare professional.
- The updated warnings note that sexual problems may contribute to mood changes.
- UK patient alert cards for finasteride, in place since 2024, cover sexual problems, depression and suicidal thoughts.
MedlinePlus lists sexual side effects such as erection problems, lower sex drive and ejaculation problems. These may occur during treatment and after it has stopped. Women, especially those who are or may become pregnant, should not touch broken or crushed finasteride tablets, because this may harm an unborn baby.
In Türkiye, the patient leaflet for finasteride tablets used for hair loss is published by the Turkish Medicines and Medical Devices Agency (TITCK). It carries the same mood warning: if you notice low mood, depression or suicidal thoughts, stop the tablet and contact your doctor as soon as possible. It also states that the medicine should not be used by women.
Minoxidil. MedlinePlus advises calling your doctor immediately for chest pain, a fast heartbeat or light-headedness. The same applies to swelling of the face or limbs, weight gain, or trouble breathing, especially when lying down. The US label adds faintness, dizziness, swollen hands or feet, and scalp redness or irritation. Stop using it and ask a doctor if any of these occur.
Any new medicine. Allergic reactions can happen with medicines used around surgery, including antibiotics and anti-inflammatory painkillers.
When to See a Doctor
- Low mood, depression or thoughts of self-harm while taking finasteride: stop the tablet and seek medical help promptly.
- Sexual side effects that worry you or do not go away: talk to a healthcare professional.
- Any of the minoxidil warning signs above: stop using it and contact a doctor.
- A rash or itching after starting a new medicine: contact your clinic or the doctor who prescribed it.
- Sudden swelling of the lips, mouth, throat or tongue, or difficulty breathing: call emergency services straight away.
- Severe pain or any unexpected symptom after surgery: contact your clinic as soon as possible.
The short-term medicines around a hair transplant are chosen and prescribed by your surgeon. Long-term treatment is a separate medical decision, with real benefits and real side effects. Before any procedure, the doctor needs to review what you already take. If you are considering one, you can ask our team for an assessment and bring a full list of your medicines and supplements.
