A Pilar Cyst on the Scalp: Drainage or Removal?

A lump that catches on your comb can make an ordinary hair routine uncomfortable. Arrange an assessment for a new scalp lump before assuming it is a cyst. If a pilar cyst has been diagnosed, ask whether it can be left alone or whether a procedure would address the problem you are having.¹

Start with the diagnosis and the reason for treatment

A clinician assesses the lump; if the diagnosis is uncertain, removal and microscopic examination may be used. Small, confirmed cysts that cause no trouble can be left alone. Repeated infection or interference with daily life can support a removal discussion.¹

Describe what bothers you, including whether the lump catches during styling or has changed. Ask the clinician to explain the diagnosis and the reason for the proposed next step. Request advice about which changes should lead you to contact the clinic sooner.

Drainage leaves a different follow-up question

Lancing drains a cyst through a small incision, sometimes followed by a dressing inside the wound. Because the sac remains, the cyst can return.¹

If drainage is proposed, ask what it is intended to achieve now and what follow-up will be needed. Request a demonstration of any dressing care you will do at home. Tell the team if the location makes that difficult and ask what help is available.

Complete removal includes the sac

Removing the whole sac and its contents lowers the chance of that cyst returning. Surgical removal can use local anaesthetic and leaves a scar. It does not prevent new cysts forming elsewhere.¹

Ask how the proposed procedure fits the size and location of your cyst. Discuss the expected scar, the closure and the arrangements for checking the wound. Request written directions about washing, brushing and hair appointments while the area heals.

Take the next-step instructions home

Before deciding, ask the clinician to compare leaving the cyst alone, drainage and removal for your circumstances. Be clear about what you want addressed and what concerns you about a procedure. If you need time to think, ask how to contact the team with further questions.

If treatment is arranged, confirm the date, any preparation and whom to contact afterward. Keep the report and care instructions together. At follow-up, ask whether any further assessment or treatment is recommended.

Hair, Everywhere includes a monthly Hair Log and a red-flag list and visit script. Use the Log to organize observations for the clinician and the visit script to prepare the questions you want answered. See the book.
