How to Prepare for a Hair Transplant: Checklist (2026)

Last updated: September 2026

Quick answer: Preparation starts two weeks before surgery. Blood-thinning medications and supplements come off on a schedule a doctor sets, smoking and alcohol have hard deadlines, and the clinic runs blood tests before anyone picks up an instrument. Every clinic sends its own pre-op list. This checklist shows standard practice, so you can see what your clinic's list covers and what to ask about.

Your clinic's written instructions and your own doctor's advice take priority over these general timelines.

What should you stop taking before a hair transplant?

Anything that thins the blood, and nothing on your own decision. The timing below is standard practice, but the sign-off always belongs to a doctor: your own doctor for anything prescribed, the clinic for the rest. A scalp that bleeds more than expected makes extraction slower and graft survival worse, which is why this list exists.

Just as important is what does not stop. Finasteride usually continues right through surgery. Chronic medication for blood pressure, diabetes, thyroid or mental health is not paused, it is reported: the clinic plans around it. The dangerous move is quietly stopping a prescribed drug to be a "good patient." Report everything, stop only what a doctor tells you to stop.

When do you have to stop alcohol and smoking?

Alcohol stops at least 3 days before surgery, and a full week is better. Smoking stops 1 to 2 weeks before, which matches the American Society of Plastic Surgeons' guidance for surgical healing. Both bans continue after surgery, so the trip itself stays dry and smoke-free.

The two work against you differently. Alcohol thins the blood and interacts with the local anesthetic, so it raises bleeding on the table. Smoking narrows the small vessels that feed the scalp, so it starves the grafts exactly when they are trying to take. One ruins surgery day, the other ruins the weeks after it.

Caffeine sits in a milder category. Many clinics are fine with one or two cups of coffee on surgery morning and only ask you not to overdo caffeine that day, since large amounts can raise blood pressure and bleeding. If your clinic bans it outright, its list wins.

What blood tests do clinics run before a hair transplant?

The standard pre-op panel covers HBsAg (hepatitis B), Anti-HCV (hepatitis C) and HIV, and beyond those three the panel varies from clinic to clinic. Some add a blood count, a clotting screen or a glucose check, others keep it minimal. Ask the clinic you are talking to exactly which tests it runs and when. That single question tells you a lot about how seriously the medical side is taken.

The tests usually happen at the clinic itself, at the consultation or on surgery morning, so you rarely need to arrange anything at home. Two follow-up questions are worth sending in writing before you book: what happens if a result comes back positive, and does the price change. Policies differ. Some clinics operate with additional sterilization protocols, some decline the case, and you want to know which type you booked before you fly, not after.

If you have a known condition, diabetes and clotting disorders above all, tell the clinic at the consultation stage and expect them to ask for clearance from your own doctor. A clinic that shrugs at a chronic condition is not being easygoing. It is skipping a step.

What should you do in the two weeks before a hair transplant?

Work backwards from surgery day: the pre-op list and the smoking cut-off start two weeks out, supplements stop one week out, alcohol stops at least three days before, and the last 48 hours are for rest and a clean scalp.

Two weeks out

• Ask the clinic for its written pre-op list. If none arrives, that silence is a warning sign, covered in our guide on whether a hair transplant in Turkey is safe
• Report every medication and supplement you take, with doses
• Start cutting down smoking, with the goal of zero by this week's end
• Last call for hair dye or chemical treatments on the scalp
• If you take prescription blood thinners, this conversation with your own doctor should already be done

One week out

• Stop vitamin E, fish oil and herbal supplements
• Stop minoxidil if the clinic's list says so
• Stop alcohol no later than 3 days before surgery; a full week off is better
• Buy button-up shirts and a U-shaped travel pillow, both on the packing list in our Day 0 to 3 trip plan
• Confirm your flight, transfer and consultation times with the clinic

48 hours out

• No alcohol: it should have stopped at least 3 days before surgery
• Last heavy workout, then the gym waits until the clinic clears it after surgery
• Sleep properly. Surgery day is long and starts early

The night before

• Wash your hair normally, then nothing goes in it: no gel, spray or leave-in products
• Eat a normal dinner, keep it light
• Lay out a button-up shirt and comfortable trousers for the morning
• Charge your phone and the power bank

The morning of

• Eat breakfast. The procedure runs under local anesthesia and an empty stomach makes the day harder
• One or two cups of coffee at most, unless the clinic says none
• No creams, lotions or styling products on the scalp
• Arrive with clean, dry hair and a shirt that buttons

What happens if you break a rule?

Most slips change the plan, not the surgery. A missed supplement deadline or a drink three days out usually means the team adjusts and watches bleeding more closely. What actually causes harm is hiding it. The anesthetic dose, the bleeding management and the timing all assume the information you gave is true.

The two exceptions that genuinely move outcomes: blood thinners taken close to surgery raise bleeding enough to affect graft survival, and smoking through the recovery window starves healing tissue, the mechanism behind some of the complications in our safety guide. If you broke a rule, say so at the door. Clinics reschedule for honesty. They cannot fix what they never heard.

The Bottom Line

Preparation is two weeks of small subtractions: blood thinners out on a doctor's schedule, supplements out a week ahead, alcohol out days before, cigarettes out earliest of all, and everything you take reported rather than hidden. A good clinic hands you this list without being asked. This page exists so you can check the list you were handed.

FAQ

Can I take paracetamol before a hair transplant?

Yes. Paracetamol (acetaminophen) does not thin the blood, which makes it the standard choice for a headache in the pre-op window. The painkillers to avoid are aspirin and NSAIDs like ibuprofen. When in doubt, name the exact product to your clinic.

Should I stop finasteride or minoxidil before surgery?

Finasteride, usually no. It works hormonally, not on bleeding, and clinics commonly keep patients on it through surgery. Minoxidil usually pauses 3 to 7 days before, because it irritates the scalp the team is about to work on. Both restart when the clinic says so, typically within weeks.

What happens if I drank alcohol two days before my hair transplant?

Tell the clinic, before surgery, not after. One or two drinks two days out rarely cancels anything; the team may adjust and will watch bleeding more closely. Saying nothing is the only version that creates real risk, because the anesthesia plan assumes your answers were honest.

Do I need to shave or cut my hair before arriving?

No. The clinic shaves what needs shaving on surgery morning, to its own specification. Arriving pre-shaved can actually work against you, since the team wants to see your natural growth pattern, and longer hair matters if a no-shave or DHI plan is on the table.

Can I exercise the week before a hair transplant?

Yes, up to about 48 hours before surgery. After that, no gym, heavy lifting or contact sport until the clinic clears you, usually 10 to 14 days after the operation. Walking stays fine the whole way through.
