It is a routine question and a fair one, particularly if surgery falls near a holiday or an occasion. The guidance is straightforward, and the reasons are practical rather than moralising.
Before surgery
Avoid alcohol for at least 48 hours before your procedure, and ideally three days. Alcohol thins the blood and dilates blood vessels, which can mean more bleeding during extraction and implantation. More bleeding makes the surgery slower and can make graft placement more difficult.
It also dehydrates you, and being well hydrated makes a long day in the chair considerably more comfortable.
After surgery
Avoid alcohol for at least the first week. In the early days it works against you in three ways: it worsens the swelling that peaks around day three or four, it can increase bleeding from healing sites, and it interferes with sleep quality at exactly the point where rest helps healing.
There is also a practical issue. Alcohol makes people less careful, and the first week is when an accidental knock or a night spent face-down in a pillow can cost you grafts.
Interactions with medication
You may be given antibiotics, anti-inflammatories or painkillers after your procedure. Some do not mix well with alcohol. Check the specific advice in your aftercare pack rather than assuming, and ask us if you are unsure.
When can you drink normally?
Most people can return to their usual habits after about a week to ten days, once swelling has settled and any prescribed medication is finished. Moderation for the first month is sensible while healing completes, but there is no long-term restriction.
Does alcohol affect hair loss itself?
Heavy, sustained drinking can affect nutrition, sleep and general health, all of which influence hair quality, and it can contribute to shedding indirectly. Moderate drinking is not a recognised cause of pattern hair loss, which is driven by genetics and hormones.
Frequently asked questions
Can I have one drink the night before?
We would rather you did not. Give yourself at least 48 hours clear, so bleeding is not increased on the day.
What if I have an event in the first week?
Go, and skip the alcohol. Also be careful of crowds, low doorways and anything that might knock the grafts.
Does alcohol affect graft survival?
Not directly in the way smoking does, but through increased bleeding, worse swelling and poorer sleep it makes the early healing period harder than it needs to be.
When can I resume normal drinking?
Generally after seven to ten days, provided you have finished any medication and swelling has settled.
