Pilar cyst removal is a minor surgical procedure where a nurse practitioner removes the entire cyst sac through a small incision under local anesthetic.
At Pinkal Medical Aesthetics in London, Ontario, scalp cyst removal is performed in-clinic by experienced nurse practitioners, and most patients walk out the same day.
If you have a firm lump on your scalp that keeps growing, this guide covers everything you need to know before booking a pilar cyst surgery consultation.
TL;DR: What You Need to Know
- A pilar cyst is a benign, keratin-filled lump that grows from a hair follicle, most often on the scalp
- The standard treatment is surgical excision, not drainage
- The entire cyst sac must be removed to lower recurrence risk
- Recovery takes 7 to 10 days, with sutures removed at a follow-up visit
- Pinkal Medical Aesthetics is a nurse practitioner-led minor surgery clinic in London, Ontario that performs pilar cyst removal in a single office visit
What Is a Pilar Cyst?
A pilar cyst (also called a trichilemmal cyst) is a benign lump that forms from the outer root sheath of a hair follicle.
About 90% of pilar cysts develop on the scalp.
How to recognize one:
- Firm, smooth, dome-shaped bump under the skin
- Moves slightly when pressed
- Filled with dense keratin (the protein in hair and nails)
- Usually painless unless inflamed
- Can range from pea-sized to several centimeters
- May appear as a single lump or in clusters
Pilar cysts do not resolve on their own. They tend to grow slowly over months or years.
Most patients first notice them while brushing hair, wearing a hat, or running fingers across the scalp.
What Causes a Pilar Cyst to Form?
Pilar cysts develop when the lining of a hair follicle traps keratin instead of shedding it normally. The keratin accumulates inside a closed sac beneath the skin.
Contributing factors include:
- Genetics. Pilar cysts run in families. If a parent has them, your risk increases
- Blocked hair follicles. Damage or obstruction to the follicle can trigger cyst formation
- Hormonal factors. They appear more frequently in women
- Age. Most common in adults between 25 and 55
There is no proven way to prevent pilar cysts from forming. Early removal can manage them before they grow larger.
Pilar Cyst vs. Sebaceous Cyst: How Are They Different?
Both look like lumps under the skin, but they have different origins and removal considerations.
If you are unsure whether your lump is a cyst, a mole, or something else entirely, read our guide on skin tags vs moles vs warts to help narrow it down.
- Why this matters: The thicker wall of a pilar cyst often makes it easier to remove in one piece. This lowers the chance of leaving tissue behind that could regrow.
At Pinkal Medical Aesthetics, we handle both sebaceous and pilar cyst removal, as well as mole removal. Your nurse practitioner confirms the type during consultation.
When Should You Get a Pilar Cyst Checked?
Not every pilar cyst needs immediate removal. But certain signs mean you should book a clinical assessment.
If you have noticed other skin growths alongside your cyst such as warts or raised lesions our wart removal and lipoma removal in London, Ontario pages may also be relevant to your situation.
See a professional if you notice:
- Rapid growth over a few weeks
- Redness, warmth, or tenderness around the lump
- Fluid drainage or foul-smelling discharge
- Pain when brushing hair, sleeping, or wearing headwear
- A new scalp lump you cannot identify
- Multiple lumps forming in the same area
Important: Any scalp lump that changes quickly, bleeds, or causes pain should be assessed promptly. While pilar cysts are almost always benign, a clinical exam rules out other conditions.
Nurse practitioner Pinkal Gandhi and the team at Pinkal Medical Aesthetics can evaluate your scalp lump during a single appointment in London, Ontario.
How Is a Pilar Cyst Removed?
Pilar cyst surgery is a straightforward cyst excision procedure performed in-clinic under local anesthetic.
Step 1: Consultation and Diagnosis
- Your nurse practitioner examines the lump
- They review your symptoms and medical history
- A physical exam is usually enough to confirm the diagnosis
- In some cases, a biopsy may be performed for closer tissue examination
Step 2: Local Anesthetic
- A small amount of local anesthetic numbs the area
- You stay awake and comfortable throughout the procedure
Step 3: Surgical Excision
- A precise, minor incision is made over the cyst
- The entire cyst sac is removed intact
- Removing the full sac is the most critical step to prevent recurrence
Step 4: Closure and Aftercare
- The incision is closed with sutures
- You receive clear wound care instructions
- A follow-up appointment is scheduled for suture removal
Typical procedure time: 20 to 45 minutes, depending on cyst size and location.
Pro Tip: If you have multiple pilar cysts, ask about removing them in a single session. This saves time and reduces the number of recovery periods.
Why Drainage Alone Does Not Work
Some walk-in clinics offer cyst drainage. This punctures the cyst and squeezes out the contents. It may provide temporary relief, but the cyst almost always returns.
If you have ever wondered why a cyst keeps coming back after drainage, our post on It's just a cyst until it hurts to sit, walk, or sleep explains exactly what happens when a cyst sac is left behind.
Drainage vs. excision:
- Drainage leaves the cyst wall intact. The sac refills with keratin and the lump comes back
- Incomplete removal increases infection and scarring risk
- Full surgical excision removes the entire sac, which significantly lowers recurrence
At Pinkal Medical Aesthetics, we prioritize complete excision over drainage for this reason.
Pilar Cyst Removal Recovery Time: What to Expect
Recovery after scalp pilar cyst removal is typically quick. Most patients return to normal activities within a day or two.
Recovery Timeline
- Day 1 to 3: Mild swelling, tenderness, or bruising. Over-the-counter pain relief is usually enough
- Day 3 to 7: Swelling begins to go down. Keep the area clean and dry
- Day 7 to 10: Follow-up visit for suture removal and healing check
- Week 2 to 4: Incision site continues to flatten and fade
Aftercare Do's and Don'ts
Do:
- Keep the wound clean and dry as directed
- Take over-the-counter pain medication if needed
- Attend your follow-up appointment on schedule
- Sleep on the opposite side if the cyst was on one side of the scalp
Don't:
- Submerge the wound in water (no swimming or baths until sutures are out)
- Pick at the wound or remove the bandage early
- Do heavy lifting or intense exercise for the first 3 to 5 days
- Apply any creams or ointments not recommended by your provider
When to call the clinic: Contact Pinkal Medical Aesthetics if you notice increasing redness, pus, spreading warmth, fever, or heavy bleeding at the incision site.
Does Pilar Cyst Removal Leave a Scar?
Some scarring is expected after any incision-based procedure. On the scalp, scars tend to heal well because hair covers the area.
What affects scarring:
- Cyst size (smaller cyst = smaller incision = less visible scar)
- Location on the scalp
- Your skin's natural healing response
- How well you follow aftercare instructions
- Whether you are prone to raised (hypertrophic) scarring
Our nurse practitioners use the smallest incision necessary. If scarring is a concern, bring it up during your consultation so expectations are set upfront.
Do Pilar Cysts Keep Coming Back?
Complete surgical excision significantly reduces recurrence. The most common reason a pilar cyst returns is that part of the sac wall was left behind.
To minimize the chance of recurrence:
- Choose a provider experienced in full cyst excision, not just drainage
- Follow all aftercare instructions carefully
- Monitor the area and schedule a follow-up if a new lump forms
A note on genetics: People with a family history of pilar cysts may develop new cysts in different locations over time. This does not mean the original removal failed. It means the underlying genetic tendency continues.
Is Pilar Cyst Removal Covered by OHIP?
OHIP coverage depends on whether the removal is considered medically necessary.
What may be covered:
- Cysts that are infected, rapidly growing, or causing significant symptoms
- Cases where your physician suspects a condition other than a benign cyst
- Removals referred by a family doctor with supporting documentation
What is typically not covered:
- Elective removal of stable, asymptomatic cysts
- Removal for purely cosmetic reasons
Pilar Cyst Removal Cost in Canada
Private clinic fees for cyst excision in Ontario generally range from $300 to $800, depending on:
- Cyst size and complexity
- Number of cysts removed
- Location on the body (facial cysts may cost more due to cosmetic precision)
Some extended health insurance plans cover a portion of private cyst removal. Check with your provider.
Pro Tip: If your family doctor referred you and the cyst is symptomatic, bring the referral documentation to your consultation. It may be relevant to coverage.
At Pinkal Medical Aesthetics, we discuss pricing transparently during consultation. No hidden fees.
Who Is a Good Candidate for Pilar Cyst Removal?
Most adults with a confirmed pilar cyst are candidates for excision. Pinkal Medical Aesthetics also performs other minor surgical procedures including ganglion removal, so if you have more than one concern, they can often be addressed in the same visit.
You may be a good candidate if:
- You have a diagnosed or suspected pilar cyst on your scalp or elsewhere
- The cyst is growing, uncomfortable, or cosmetically bothersome
- You want a lasting solution rather than temporary drainage
- You are in generally good health with no uncontrolled bleeding disorders
You may not be a candidate if:
- You have an active skin infection at the cyst site (this may need treatment first)
- You are on blood-thinning medications that cannot be adjusted (discuss with your provider)
- The lump has not been assessed and the diagnosis is unclear
Treatment suitability always depends on an in-person clinical assessment.

Frequently Asked Questions
1. Is pilar cyst removal painful?
The area is numbed with local anesthetic before the procedure. You may feel mild pressure during excision, but pain is rare. Some tenderness after the anesthetic wears off is normal and manageable with over-the-counter medication.
2. How long does the procedure take?
Most pilar cyst excisions take 20 to 45 minutes. This includes numbing, removal, and wound closure. Single scalp cysts on accessible areas tend to be on the shorter end.
3. Can I go back to work the same day?
Yes, in most cases. Desk work, driving, and light tasks are generally fine. Avoid heavy physical activity for the first few days.
4. Will the cyst grow back after surgery?
Recurrence is uncommon when the entire cyst sac is removed. Drainage alone has a much higher recurrence rate because the sac stays intact. Full excision is the standard at Pinkal Medical Aesthetics.
5. Do I need a referral to book?
No referral is required. You can contact Pinkal Medical Aesthetics directly to schedule a consultation. If you have a referral from your family doctor, bring it along as it may help with insurance or OHIP coverage considerations.
