Hair Transplant Anaesthetic: Local or General?
Last reviewed on 25 July 2026. We review our treatment guides every six months to keep them accurate.
A hair transplant is done under local anaesthetic, which means you stay awake throughout while your scalp is numbed so you do not feel pain. You are not put to sleep. A general anaesthetic, the type that makes you unconscious, is not standard for a hair transplant and is generally neither used nor needed. This guide explains what happens, why local anaesthetic is used, and what being awake actually feels like. It is general information rather than personal medical advice, so please follow the specific guidance of your surgeon and clinic.
For an independent overview, the NHS page on the local anaesthetic explains that it numbs an area of the body so you are awake but do not feel any pain during an operation or procedure. That is exactly how it is used for a hair transplant, applied to the scalp.
The short answer
A hair transplant is carried out under local anaesthetic, so you are awake the whole time
The scalp is numbed with small injections, so the treated area feels no pain during the procedure
Being put to sleep with a general anaesthetic is not standard, and is generally not used or needed for a hair transplant
Some clinics offer mild sedation to help you relax, but even with sedation you stay awake
The numbing injections are the only briefly uncomfortable part; once the area is numb the transplant itself should be pain free
The exact anaesthetic, and whether any sedation is offered, are decisions for your surgeon and clinic based on you
What local anaesthetic is, and how it is given
A local anaesthetic is a medicine that numbs one specific area of the body. According to the NHS, it works by stopping the nerves in that area from sending pain signals to your brain, so you stay fully awake and aware while the treated area feels numb. Unlike a general anaesthetic, it does not make you unconscious and does not affect your breathing, heart rate or blood pressure.
For a hair transplant, the anaesthetic is injected into the scalp to numb both the donor area, where the follicles are taken from, and the recipient area, where they are placed. Once it has taken effect the area should feel nothing sharp during the procedure. As the Royal College of Anaesthetists notes in its patient information, with a local anaesthetic you stay conscious and free from pain, although you may still feel some tugging or pulling around the area being worked on.
The injections themselves are the part most people find briefly uncomfortable, usually described as a short stinging sensation that settles as the area goes numb. Surgeons use several techniques to make this easier, and a review in the Journal of Cutaneous and Aesthetic Surgery lists measures such as a fine needle, a vibration tool held near the scalp, nerve blocks and slow, gentle injection to reduce the discomfort of numbing. The lidocaine and bupivacaine mentioned below are common examples of these local anaesthetics.
The numbing solution used for a hair transplant usually combines the anaesthetic, most commonly lidocaine, with a small amount of adrenaline, also called epinephrine. A StatPearls pharmacology reference explains that adrenaline narrows nearby blood vessels, which reduces bleeding during the procedure and can make the numbing last longer. This is a routine, well-established combination.
Because adrenaline can slightly raise heart rate and blood pressure, the same reference notes it needs careful consideration in people with cardiovascular conditions, such as an irregular heartbeat, heart disease, or high blood pressure that is not well controlled, and in those who take medicines for their heart or blood pressure. This is not a reason to assume you cannot have a hair transplant. It is why it matters to tell your clinic about all your medical conditions and medicines at your consultation, so your surgeon can assess what is suitable and safe for you.
Optional sedation to help you relax
Some clinics offer a mild sedative, often taken as a tablet, to help you feel calm and relaxed on the day. This is not the same as a general anaesthetic. The Royal College of Anaesthetists explains that sedation makes you feel drowsy and relaxed while you remain awake, and it is sometimes added when a person having a local anaesthetic would prefer not to feel fully alert. Whether sedation is offered, and whether it is suitable for you, is something to discuss with your surgeon and clinic. If you are given a sedative, you will usually be advised to arrange for someone to take you home afterwards.
Why a general anaesthetic is not used
A general anaesthetic is not used because it is unnecessary for numbing only the scalp, carries greater risks, and needs an anaesthetist and longer recovery.
A general anaesthetic is the type that puts you fully to sleep. The NHS describes it as being given medicine so that you are unconscious and do not feel anything during an operation, and it explains that a general anaesthetic is used only when other options, such as a local anaesthetic or sedation, are not suitable. (You may also see the American spelling, anesthesia, in some sources; the meaning is the same.)
A hair transplant does not meet that threshold. The procedure only needs the scalp to be numbed, and a local anaesthetic does this completely, so there is no benefit to being put to sleep. Because of that, a general anaesthetic is generally avoided for a hair transplant, and there are good reasons why:
It is unnecessary. The whole procedure can be carried out comfortably with only the scalp numbed, so being made unconscious adds nothing.
It carries greater risks. The NHS lists possible effects of a general anaesthetic such as feeling sick, a sore throat from the breathing tube, and, rarely, more serious complications. A local anaesthetic is generally very safe, with serious side effects very rare.
It needs an anaesthetist and more monitoring. A general anaesthetic is given in hospital by a specialist doctor who stays with you throughout, monitoring your heart rate, blood pressure and oxygen and supporting your breathing. A local anaesthetic does not require this.
It means a longer recovery. The effects of a general anaesthetic can last around 24 hours, during which the NHS advises you must not drive, and you need someone to take you home and stay with you. With a local anaesthetic you can usually leave under your own steam once the appointment is over.
Some people ask whether they can request a general anaesthetic and be put to sleep instead. General anaesthetic is not available at My Hair Transplant Clinics. It is not needed for a procedure that only numbs the scalp, and it would add risk and cost because a general anaesthetic must be given and monitored by an anaesthetist present throughout. More widely, most hair transplant clinics do not offer general anaesthetic for the same reasons. If you have any questions about this, your clinic can talk them through with you.
Some surgeons internationally do occasionally use a general anaesthetic, but for a routine hair transplant it is not the norm and is not required. If you have particular concerns or a medical reason to ask about it, raise it with your surgeon, who can explain what is right for your situation.
What the day is actually like
Because you are awake, a hair transplant day is more relaxed than many people expect. After the scalp is numbed, the treated area should not feel painful, and a hair transplant usually takes several hours, so it is spread out rather than rushed. Most people are able to talk with the team, listen to music, watch something, and take breaks when they need them, for example to have a drink, use the bathroom or eat something light. You will not be aware of any pain from the work itself once the numbing has taken effect.
Comfort and pain relief afterwards
As the numbing wears off later in the day, it is normal to feel some mild soreness or tightness across the scalp. This is usually easily managed. Your clinic will give you aftercare instructions and, where appropriate, guidance on suitable pain relief, so follow what they provide rather than any general figure. If anything feels more painful than you were led to expect, contact your clinic.

Frequently asked questions
Are you awake during a hair transplant?
Yes. A hair transplant is done under local anaesthetic, so you are awake and aware throughout while your scalp is numbed. You will not feel pain from the procedure once the area is numb, though you may notice some tugging or pressure. Many people find the time passes comfortably, chatting, listening to music or resting between stages.
Can you be put to sleep for a hair transplant?
Being fully put to sleep means a general anaesthetic, and that is not standard for a hair transplant. The procedure only needs the scalp numbed, which a local anaesthetic does completely, so a general anaesthetic is generally not used or needed. Some clinics offer a mild sedative to help you relax, but even with sedation you remain awake. If you have a specific concern, discuss it with your surgeon.
Can I ask to be put to sleep with a general anaesthetic instead?
General anaesthetic is not available at My Hair Transplant Clinics, and most hair transplant clinics do not offer it. It is not needed for a procedure that only numbs the scalp, and it would add risk and cost because a general anaesthetic must be given and monitored by an anaesthetist present throughout. If you have questions about this, your clinic can talk them through with you.
Is a hair transplant done under general anaesthesia?
No, not as a rule. A hair transplant does not require general anaesthesia, and it is generally avoided because it is unnecessary for numbing only the scalp, carries greater risks, needs an anaesthetist and more monitoring, and involves a longer recovery. Local anaesthetic is the usual and appropriate choice.
What anaesthetic is used for a hair transplant?
A local anaesthetic, injected into the scalp to numb the donor and recipient areas. Lidocaine and bupivacaine are common examples of the medicines used; bupivacaine tends to last longer, and a small amount of adrenaline (epinephrine) is usually added to reduce bleeding and prolong the numbing. The exact choice is made by your surgeon and clinic, so the details will be explained to you as part of your care.
Does the numbing part hurt?
The numbing injections are the only briefly uncomfortable part, usually a short stinging sensation that settles quickly as the area goes numb. Techniques such as a fine needle, a vibration tool and gentle, slow injection are used to reduce this. After that, the transplant itself should be pain free.
I have a heart condition or take blood pressure medication. Can I still have a hair transplant?
Possibly, but it needs to be assessed rather than assumed. The local anaesthetic used for a hair transplant usually contains a small amount of adrenaline (epinephrine), which can slightly raise heart rate and blood pressure and so needs careful consideration in people with cardiovascular conditions. Tell your clinic about all your heart or blood pressure conditions and any medicines you take at your consultation, so your surgeon can assess what is right and safe for you.
Can I have sedation to relax during the procedure?
Possibly, depending on the clinic. Some clinics offer a mild sedative to help you feel calm while staying awake. Sedation makes you drowsy and relaxed rather than unconscious. Whether it is offered and suitable for you is a decision for your surgeon and clinic, and if you have it you will usually be asked to arrange for someone to take you home.
