Pre-SMP Prep: What to Do (and Stop Doing) Before Your Session

What you do in the days and weeks before your SMP session can directly affect the quality of your result. Most clinics send a basic instruction sheet, but it often lacks the practical detail that makes a real difference. This guide covers everything you should do — and stop doing — in the weeks, days, and hours leading up to your SMP appointment, based on practitioner recommendations and client experience.

Think of this as your comprehensive pre-SMP checklist. Following these steps won't just improve your result — it'll make your session smoother, more comfortable, and more efficient.

2-4 Weeks Before Your Session

Stop Using Hair Fibers and Concealers

If you've been using products like Toppik, Caboki, or any hair building fibers to conceal thinning areas, stop using them at least 2 weeks before your SMP session. These products leave microscopic residue on the scalp that can interfere with pigment absorption and make it harder for your practitioner to see the true state of your scalp.

The residue builds up over time, even with regular washing. Give your scalp a full 2 weeks of fiber-free washing to ensure the surface is completely clean when your practitioner starts working.

Discuss Minoxidil with Your Practitioner

If you're using minoxidil (Rogaine), talk to your SMP practitioner about whether to continue or pause it before your session. Recommendations vary by practitioner, but the most common advice is to stop applying minoxidil to the treatment area 5-7 days before your session. Minoxidil increases blood flow to the scalp, which can increase bleeding during the procedure and potentially affect pigment retention.

Important: don't stop finasteride or dutasteride — these are systemic medications that don't affect the SMP procedure. Only minoxidil (the topical) may need to be paused, and only if your practitioner recommends it.

Protect Your Scalp from Sunburn

A sunburned scalp is one of the most common reasons SMP sessions get rescheduled. Sunburned skin is inflamed, tender, peeling, and cannot hold pigment properly. If your practitioner sees significant sunburn, they'll likely postpone your appointment — and rightfully so.

In the 2-4 weeks before your session, be proactive about sun protection. Wear a hat outdoors. Apply sunscreen to your scalp daily. Avoid tanning beds completely. If you get a mild sunburn, it needs at least 7-10 days to fully heal before SMP is safe to perform.

Start a Moisturizing Routine

Well-hydrated skin holds pigment better than dry, flaky skin. Starting a daily moisturizing routine 2-4 weeks before your session ensures your scalp is in optimal condition for pigment absorption. Use a gentle, oil-free moisturizer — something like CeraVe or Cetaphil facial moisturizer works perfectly.

Apply daily after showering. This serves double duty: it improves pigment retention and gives you practice with the moisturizing routine you'll want to maintain after your SMP heals.

Address Any Scalp Conditions

If you have dandruff, psoriasis, eczema, or any other scalp condition, get it under control before your session. Active scalp conditions can affect pigment absorption, increase discomfort during the procedure, and complicate healing. If you have a chronic scalp condition, consult with your dermatologist about managing it in the weeks leading up to your SMP appointment.

Mild dandruff can usually be managed with a medicated shampoo (like Head & Shoulders or Nizoral) used consistently in the weeks before treatment. More severe conditions may require prescription treatment — start early so it's resolved by your appointment date.

48 Hours Before Your Session

No Alcohol

Alcohol thins the blood and increases bleeding during the procedure. More bleeding means the practitioner has to work harder to achieve consistent pigment placement, and it can affect how well the pigment deposits into the skin. Avoid alcohol for at least 48 hours before your session — 72 hours is even better.

This isn't just about heavy drinking. Even a couple of beers the night before can noticeably increase scalp bleeding during SMP. Play it safe and stay dry for the two days leading up to your appointment.

Avoid Blood Thinners and Anti-Inflammatories

If possible, avoid aspirin, ibuprofen (Advil, Motrin), and other NSAIDs for 48 hours before your session. These medications thin the blood and increase bleeding. If you need pain relief, acetaminophen (Tylenol) is fine — it doesn't affect blood clotting.

If you're on prescription blood thinners for a medical condition, do not stop taking them without consulting your doctor. Instead, inform your SMP practitioner so they can adjust their technique and expectations accordingly.

Don't Exfoliate Your Scalp

Avoid any exfoliating products, scrubs, or harsh cleansers on your scalp for at least 48 hours before your session. Exfoliation removes the top layer of skin cells, which can make the scalp more sensitive and affect how pigment is absorbed. You want your skin to be clean but intact — not freshly scrubbed and raw.

Stay Hydrated

Drink plenty of water in the 48 hours leading up to your session. Well-hydrated skin is healthier, more elastic, and holds pigment better. Aim for at least 8 glasses of water per day in the two days before your appointment.

Skip the Coffee (Morning Of)

Caffeine is a mild vasoconstrictor and can also increase sensitivity to pain. While the effect is modest, many practitioners recommend avoiding coffee on the morning of your session. If you're a serious coffee drinker and skipping it would make you miserable, have a small cup — but don't overdo it. Avoid energy drinks entirely.

Day of Your Session

Shave Your Head

Most practitioners want you to arrive with a freshly shaved head — typically shaved to a 0 guard or with a razor the morning of your appointment. This gives the practitioner a clean, even surface to work on and allows them to see the full extent of your hair loss pattern.

Important: confirm with your specific practitioner what shave length they prefer. Some want a complete razor shave. Others prefer a 0 or 1 guard clipper cut. Some want to see a day or two of growth so they can assess your natural follicle pattern. Follow their specific instructions.

If your practitioner wants a razor shave: shave the morning of your appointment, not the night before. You want the shave to be as fresh as possible, but give your skin at least 30-60 minutes to calm down after shaving before the procedure begins.

Eat a Substantial Meal

SMP sessions typically last 2-4 hours. That's a long time to sit still, and your body handles the mild stress of the procedure better when it's well-fueled. Eat a solid, balanced meal 1-2 hours before your appointment. Include protein, complex carbs, and healthy fats — think a chicken sandwich, rice bowl, or eggs with toast.

Avoid heavy, greasy meals that might make you uncomfortable sitting for hours. Also avoid extremely spicy food — some people find that spicy meals increase skin sensitivity.

Bring a snack for longer sessions. A granola bar, nuts, or fruit can help maintain your energy if the session runs 3+ hours.

Wear Comfortable, Dark-Colored Clothing

You'll be sitting in a treatment chair for several hours. Wear something comfortable that you can relax in — a loose t-shirt, joggers, or athletic wear works well. Avoid anything with a tight collar that will rub against your freshly treated scalp on the way home.

Wear dark colors. While practitioners are careful, there's a chance of minor pigment spray or blood spots getting on your clothing. Dark shirts hide this easily. Don't wear your favorite white t-shirt.

Arrive with a Clean Scalp

Wash your scalp thoroughly the morning of your session. Use a gentle cleanser — nothing exfoliating or medicated. Pat dry completely. Don't apply any products after washing — no moisturizer, no sunscreen, no aftershave, no oils. Your practitioner needs a completely clean, product-free surface to work on.

If you're arriving at a morning appointment after shaving, a simple rinse with warm water and gentle patting dry is sufficient. The goal is clean, dry, product-free skin.

What to Bring

Here's a practical packing list for your SMP session:

• Entertainment: Phone, earbuds, downloaded podcasts or music. Sessions are long, and having something to listen to helps pass the time and distract from discomfort.
• Phone charger: A 3-4 hour session will drain your battery if you're using your phone for entertainment.
• Snacks and water: For longer sessions, having your own snacks ensures you don't go hungry.
• A loose-fitting hat: You'll want to cover your scalp on the way home. Bring a clean, loose beanie or soft cap — nothing tight that will press against the fresh treatment.
• Reference photos: If you have specific photos of hairlines, density levels, or results you admire, bring them on your phone to share with your practitioner.
• Payment method: Confirm with your clinic whether they accept cards, cash, or financing — and have your payment ready.
• A comfortable pillow or neck support: Some clients bring a small travel pillow for added comfort during long sessions.

What Not to Bring

• Unrealistic expectations: SMP creates the appearance of a closely shaved head, not a full head of hair. Come in with calibrated expectations for the best experience.
• Anxiety: If you're nervous, remember that SMP discomfort is typically described as mild — like a light scratching sensation. Most clients say it's far less painful than they expected.
• Impatience: Your first session won't look like the final result. SMP is built up over 2-3 sessions. Trust the process and resist the urge to judge after session one.

The Bottom Line

Proper preparation makes a measurable difference in SMP results. The steps are simple — moisturize, hydrate, avoid alcohol and blood thinners, protect from sun, shave cleanly, and show up well-fed and comfortable. None of this is difficult, but skipping these steps can lead to suboptimal pigment retention, increased discomfort, or even postponed appointments.

Take the prep seriously, and you'll give your practitioner the best possible canvas to work with — which means the best possible result for you.
