If you just got a skin cancer diagnosis on your forehead or scalp, you've probably fallen down a Google image rabbit hole. It's scary. You see pictures of mohs surgery on head results that look like something out of a horror movie—gaping red craters where a tiny "pimple" used to be.
Honestly, it's a lot to take in.
I’ve spent years looking at these cases and talking to dermatologic surgeons like those at the Mayo Clinic and Cleveland Clinic. There is a very specific reason why the "after" photo of the surgical wound looks ten times bigger than the "before" photo of the cancer. It isn't because the surgeon was reckless. It’s because skin cancer is kinda like an iceberg.
What you see on the surface is just the tip. Underneath, those cancer cells are sending out "roots" or "fingers" into the surrounding tissue. Mohs surgery is designed to find every last one of them.

The "Iceberg Effect" in Pictures of Mohs Surgery on Head
Most people look at their basal cell carcinoma (BCC) and see a pearly bump the size of a pencil eraser. Then they see a photo of the post-Mohs defect and it’s the size of a half-dollar coin.
Why the massive gap?
Mohs micrographic surgery is unique because the surgeon acts as both the cutter and the pathologist. They take a thin layer, look at it under a microscope, and if they see cancer at the edge, they go back and take another "map" of tissue from that specific spot. They keep going until the margins are clear.
On the head, skin is tight. There isn't a lot of "extra" padding. When a surgeon removes a layer of tissue on the scalp or temple, the skin naturally pulls back and retreats, making the hole look even more dramatic than it actually is.
What the raw wound actually looks like
If you’re looking at a photo of a "raw" Mohs defect before it’s stitched up, you’re seeing:
- Yellowish fat (subcutaneous tissue): This is the layer just under your skin.
- Red muscle or fascia: Sometimes visible if the cancer was deep.
- The "Map": You might see purple or green dye marks around the edges. This is how the surgeon knows exactly where they are in the "clock" of your wound.
Forehead vs. Scalp: Why Locations Matter
A "hole" on your forehead is a completely different beast than one on your crown.
On the forehead, there are clear "expression lines." A skilled surgeon will try to hide the final scar inside one of those wrinkles. If you look at 12-month follow-up pictures of mohs surgery on head areas like the forehead, the scar often disappears into a natural crease.
The scalp is trickier. It’s incredibly vascular. This means it bleeds. A lot.
If you see a photo of a scalp wound immediately after surgery, it might look messy. But the scalp also has an amazing blood supply, which means it heals like a champ. The biggest concern for most people with scalp Mohs is hair loss. If the wound is large, the surgeon might have to use a "rotation flap," where they slide a piece of hair-bearing skin over the gap.
Sometimes, this creates a temporary "dog ear"—a little pucker of skin that looks weird for a few weeks but eventually flattens out.
The Three Stages of Healing You’ll See in Photos
You can't judge a Mohs result by the one-week photo. You just can't.
1. The "Frankenstein" Phase (Days 1–14)
This is when the stitches are in. The area will be swollen. If the surgery was near your forehead or temple, you might get a massive black eye. Gravity pulls that surgical fluid down into your eyelids. It looks like you went ten rounds in a boxing ring.
2. The "Red Ridge" Phase (Weeks 3–8)
Once the stitches come out, the scar will look like a raised, bright red or purple line. People panic here. They think, Is it infected? Usually, no. That redness is just "neovascularization"—your body building new blood vessels to repair the site. It’s a good sign, even if it looks angry.
3. The "Fading" Phase (6 Months – 1 Year)
This is where the magic happens. The body remodels the collagen. That lumpy, red line starts to flatten and turn white or flesh-colored. If you're looking at pictures of mohs surgery on head outcomes, always look for the "1-year post-op" tag. That’s the true result.

I've seen patients who had a hole the size of a golf ball on their temple. Six months later, you couldn't find the scar if you tried.
But let's be intellectually honest: some scars are visible. If the cancer was deep and required a skin graft (taking skin from behind your ear, for example, to patch the hole), the texture might never perfectly match. A graft can sometimes look like a "patch" because the skin from the ear is thinner than the skin on the forehead.
Ways surgeons hide the evidence:
- Linear Closure: Just pulling the edges together in a straight line.
- Flap Reconstruction: Moving nearby skin (which has the same color and texture) to fill the gap.
- Granulation: Sometimes, they just let the wound heal from the bottom up on its own. This often results in a surprisingly smooth, albeit slightly depressed, scar.
Specific Risks for Head and Scalp Cases
There are nerves all over your head. If you see a photo of a very deep Mohs surgery on the temple, there’s a risk to the "temporal branch" of the facial nerve. If that gets nicked, you might not be able to raise your eyebrow.
Surgeons are hyper-aware of this. They use local anesthetics and very precise "nicking" techniques to avoid these areas. If you feel a weird "zing" or numbness after surgery, that's usually temporary as the tiny sensory nerves regrow.
Actionable Next Steps for Your Recovery
If you’re staring at a fresh wound and feeling discouraged, here is what you actually need to do to make sure your "after" photo looks like the success stories:
- Keep it greasy: The "scab is good" theory is a total myth. Use Vaseline or Aquaphor. A moist wound heals up to 50% faster than a dry one and results in a thinner scar.
- Sun protection is non-negotiable: New scar tissue has no pigment. If it gets hit by UV rays in the first 6 months, it can "tattoo" the scar a dark brown color permanently. Wear a hat.
- Massage the scar: Once the stitches are out and the wound is closed (usually around week 4), gently massaging the scar helps break up the "lumpy" collagen.
- Manage your expectations: The "hole" you see today is the largest the wound will ever be. From the moment the first stitch goes in, it only gets smaller.
The reality is that pictures of mohs surgery on head results are a testament to the body's ability to knit itself back together. It looks brutal on day one, but by day 300, it's usually just a memory.
Consult with a fellowship-trained Mohs surgeon (look for the American College of Mohs Surgery or ACMS credential) to ensure they have the reconstructive expertise to handle the complex "geometry" of the human face and head.
