Call (786) 738-9515Most patients restart topical minoxidil about 24 to 48 hours after PRP — long enough for the injection channels to close so the alcohol and propylene glycol in the solution do not sting.

The usual instruction is to hold topical minoxidil for the first 24 hours and restart at the 24- to 48-hour mark, depending on how your scalp feels. Many patients simply resume with their next scheduled dose the day after treatment.
The reason is not that minoxidil interferes with PRP — it does not. The issue is the vehicle. Most topical minoxidil solutions contain alcohol and propylene glycol, which burn on skin with fresh micro-punctures and can add to redness and itching.
We generally advise against applying it in the hours right after your session. If you applied minoxidil in the morning before your appointment, that is fine and nothing needs to be done.
If you already applied it after treatment and it stung, rinse with lukewarm water and skip the next dose, then resume the following day. Applying it once early is not going to damage your results.
Foam minoxidil is typically propylene-glycol-free and is noticeably better tolerated on a treated scalp. If you use the liquid version and find it stings for the first few days after each session, switching to foam is a reasonable conversation to have with us.
Apply to a dry scalp, use the labeled amount, and do not double up to "make up" a missed dose.
Oral medications for hair loss do not need to be paused around PRP. Finasteride, dutasteride, low-dose oral minoxidil, and spironolactone all continue on schedule. They work systemically and do not touch the treated skin.
PRP is commonly used alongside these medications rather than instead of them. Combination treatment tends to outperform any single approach for pattern hair loss.
Ketoconazole, salicylic acid, coal tar, selenium sulfide, and prescription topical steroids or minoxidil-plus-tretinoin compounds are generally held for about 48 hours and then resumed as prescribed.
If you use a medicated product for a diagnosed scalp condition, tell us at your consultation so we can sequence your treatments rather than have you guess.
This is the most important line on the page. Patients occasionally stop blood pressure medication, blood thinners, or thyroid medication before a cosmetic procedure because they read something online. Do not do that.
Bring your full medication list — prescriptions, over-the-counter products, and supplements — to your consultation. We build the PRP schedule around your medications, and we will tell you clearly if anything genuinely needs adjusting, in coordination with your prescribing physician.
Most patients restart topical minoxidil 24 to 48 hours after PRP, once the scalp is no longer tender.
Yes. Minoxidil and PRP are frequently combined. The only change is a short pause of the topical form right after your session.
No. Minoxidil does not reduce the effect of PRP; the short pause is only to avoid stinging from the alcohol and propylene glycol in the solution.
No. Oral finasteride, dutasteride, and low-dose oral minoxidil continue on their normal schedule.
Usually about 48 hours after treatment, then resume as prescribed.
