You can return to your normal diet approximately 10 days after a hair transplant. Consuming garlic in your meals during this period is not expected to damage the transplanted grafts or negatively affect hair growth. However, I advise you to be more cautious regarding vitamins and dietary supplements that contain garlic. In particular, the use of high-dose garlic supplements can affect platelet function and potentially increase the risk of bleeding. For this reason, I recommend avoiding high-dose garlic supplements during the initial 10–14 day recovery period following your hair transplant, and consulting with your doctor before using any supplements. In summary, there is no issue with consuming normal amounts of garlic. The primary concern to be aware of is the use of supplements that contain high doses of garlic.
