Stop alcohol at least 1 week and all nicotine products at least 2 weeks before both FUE and FUT surgery. These restrictions are the same for both methods because alcohol and nicotine damage graft survival through the same mechanisms: blood thinning, vessel constriction, and impaired healing. The main difference is that FUT requires slightly longer abstinence after surgery because the sutured donor strip is more sensitive to these substances.

How Alcohol Affects FUE vs FUT
Alcohol thins the blood by reducing platelet aggregation. During surgery, this means more bleeding at every graft insertion site. Excess bleeding forces the surgeon to spend more time controlling hemorrhaging and less time on precise graft placement. The result is lower graft survival for both methods.
Before Surgery: Same Rules
Stop all alcohol at least 7 days before either FUE or FUT. This allows your blood's clotting ability to return to normal. Even moderate drinking within 48 hours of surgery significantly increases intraoperative bleeding.
After Surgery: FUT Needs Longer
FUE patients can typically resume moderate alcohol consumption after 7 days. The small dot extraction sites have closed by this point, and the recipient area has healed enough that blood thinning poses minimal risk.
FUT patients should wait 10-14 days. The sutured donor strip is a larger wound under tension, and alcohol's blood-thinning properties increase the risk of bleeding along the suture line. Wait until after suture removal and your surgeon confirms proper wound closure.
How Smoking Affects FUE vs FUT
Nicotine constricts blood vessels throughout the body, reducing blood flow to the scalp by up to 30%. Transplanted grafts depend entirely on blood supply from the recipient area to survive and grow. Restricted blood flow directly reduces the percentage of grafts that take root.
Before Surgery: Same Rules
Stop all nicotine products at least 14 days before either FUE or FUT. This timeline allows blood vessels to recover their normal dilation capacity. Surgeons consistently report better graft survival rates in patients who fully abstain before surgery.
After Surgery: FUT Needs Longer
FUE patients should avoid nicotine for at least 2 weeks after surgery. The dot extraction sites heal quickly and are less dependent on sustained blood flow for wound closure.
FUT patients should avoid nicotine for 3-4 weeks after surgery. The linear donor wound requires strong blood supply for proper healing. Smoking during FUT recovery increases the risk of:
- Scar widening from poor wound healing
- Wound dehiscence (opening of the suture line)
- Visible scarring that becomes more noticeable over time
- Slower overall recovery

What If You Slip Up
If you drink or smoke during the restricted period, contact your surgeon. A single drink on day 5 after FUE is unlikely to cause major problems, but your surgeon needs to know so they can adjust your care plan. Smoking even one cigarette reintroduces nicotine's vessel-constricting effects and can set back your recovery.
Do not try to hide substance use from your surgical team. They are not there to judge you. They need accurate information to give you the best possible results.
Long-Term Impact on Results
Both FUE and FUT follow the same growth timeline: shock loss at weeks 2-4, new growth at months 3-4, and full results at 12-18 months. Smoking during the first 3 months can reduce final graft survival by a measurable percentage. Patients who quit smoking permanently often see better long-term hair quality because improved blood flow benefits all hair follicles, not just transplanted ones.

FAQ
How long before FUE or FUT should I stop drinking alcohol?
Stop drinking alcohol at least 1 week before both FUE and FUT surgery. Alcohol thins the blood, interferes with anesthesia, and increases bleeding during the procedure. Excessive bleeding makes graft placement harder for the surgeon and reduces graft survival rates for both methods.
When can I drink alcohol after FUE vs FUT?
Wait at least 1 week after FUE and 10-14 days after FUT before drinking alcohol. FUT requires a longer wait because alcohol's blood-thinning effect poses a greater risk to the sutured donor strip, which is under tension and more prone to bleeding than FUE's small dot extraction sites.
How long before a hair transplant should I stop smoking?
Stop all nicotine products at least 2 weeks before both FUE and FUT. Nicotine constricts blood vessels and reduces oxygen delivery to the scalp. Poor blood flow during surgery results in lower graft survival rates. This applies equally to cigarettes, vapes, nicotine patches, and nicotine pouches.
When can I smoke after FUE vs FUT?
Wait at least 2 weeks after FUE and 3-4 weeks after FUT before resuming nicotine products. FUT has a longer restriction because the sutured donor strip depends on strong blood supply for proper wound closure. Smoking during FUT recovery increases the risk of scar widening and poor wound healing.
Does vaping count as smoking for hair transplant recovery?
Yes. Vaping delivers nicotine, which causes the same blood vessel constriction as cigarette smoking. The restrictions on smoking before and after FUE and FUT apply equally to all nicotine delivery methods, including vapes, nicotine pouches, patches, gums, and chewing tobacco.
Can I use marijuana before or after a hair transplant?
Avoid smoking marijuana for 2 weeks before and after both FUE and FUT. Smoked marijuana causes the same combustion-related blood flow problems as cigarettes. THC edibles do not carry vascular risk from combustion but can interact with anesthesia and post-operative medications. Disclose all substance use to your surgeon.
