Medication timeline before and after transplant

What should you do with medication before hair transplant surgery?

Before hair transplant surgery, you should ideally already be established on medication months ahead so any initial shedding has resolved; disclose everything you take, including supplements, weeks ahead; follow clinic instructions on pausing topicals and anything affecting bleeding in the final days; and never stop a prescribed systemic medication on your own initiative.

• Months ahead: ideally already established on treatment, so any initial shedding phase has resolved and tolerance is known
• Weeks ahead: disclose everything you take, including supplements
• Days ahead: follow clinic instructions on pausing topicals and anything affecting bleeding
• Never: stop a prescribed systemic medication on your own initiative

What happens to medication around the day of hair transplant surgery?

Around hair transplant surgery, topical Minoxidil is commonly paused shortly beforehand and not applied to the healing recipient area afterwards, because it irritates the scalp and acts as a vasodilator. Finasteride is generally continued, while anticoagulants and antiplatelet drugs remain a separate decision for the prescribing doctor.

What happens to medication in the weeks and months after a hair transplant?

After a hair transplant, nothing beyond clinic-supplied products should touch the recipient area for weeks 0 to 2. Topical Minoxidil typically resumes around weeks 2 to 4 once healing allows. Systemic medication continues long term to protect native hair, while months 3 to 12 form the growth phase.

• Weeks 0 to 2: nothing on the recipient area beyond what your clinic supplied
• From around weeks 2 to 4: topical Minoxidil typically resumed once healing allows, on clinic instruction
• Ongoing: systemic medication continued long term to protect native hair
• Months 3 to 12: the growth phase, during which medication is doing its own separate job

Why does medication timing matter for interpreting post-transplant shedding?

Starting Minoxidil shortly before hair transplant surgery can trigger a shedding phase that overlaps with post-operative shock loss; both are temporary, but together they are alarming and impossible to attribute to one cause. Being on stable treatment beforehand keeps the two apart and makes recovery easier to read.

The post-operative half of that timeline is detailed under aftercare.
