Pilar Cyst Removal: Causes, Treatment Options, and Recovery
Unlike other types of cysts, pilar cysts form from hair follicle cells, which is why they are most often found on the scalp. They are more common in adults, particularly women, and may run in families. While some cysts remain small, others can grow significantly and may require medical attention.
This article explains why pilar cysts develop, when removal is necessary, and what to expect from treatment and recovery. Whether a cyst is causing discomfort or is simply an aesthetic concern, knowing the available options can help in making an informed decision.
What Are Pilar Cysts and Why Do They Develop?
Pilar cysts are benign growths that form under the skin, originating from hair follicle cells. They are most commonly found on the scalp, where hair follicles are densely packed, but they can also develop in other areas of the body. These cysts are usually smooth, round, and firm, often moving slightly when pressed.
Causes and Risk Factors
Blocked hair follicles – Pilar cysts develop when keratin, a protein found in hair and skin, becomes trapped under the skin instead of shedding normally.
Genetics – There is evidence that pilar cysts may run in families, making some individuals more prone to developing them.
Age and gender – These cysts are most commonly seen in middle-aged adults, with women experiencing them more frequently than men.
Scalp trauma or irritation – Damage to the scalp from injuries, hair treatments, or chronic irritation may contribute to cyst formation.
How to Identify a Pilar Cyst
Feature
Description
Size
Typically 1-5 cm, but can grow larger over time.
Location
Most commonly found on the scalp, but may occur elsewhere.
Texture
Smooth, firm, and round. Moves slightly under the skin when pressed.
Pain Level
Usually painless, but may become tender if inflamed or infected.
Growth Rate
Slow-growing over months or years.
Appearance
Skin-coloured or slightly yellow. May have a small central opening.
While pilar cysts are generally harmless, they can become irritating, inflamed, or infected, prompting some individuals to seek medical removal. Dermatologists and surgeons can confirm whether a lump is a pilar cyst and recommend the most appropriate treatment options.
When Is Removal Necessary?
Pilar cysts are benign and often do not require immediate treatment. However, in some cases, removal may be recommended, especially if the cyst is causing discomfort, growing larger, or becoming infected. Treatment options range from watchful waiting to surgical excision, depending on the size and symptoms of the cyst.
Medical vs. At-Home Management
Monitoring – If the cyst is small and not bothersome, some patients choose to leave it untreated. However, pilar cysts do not disappear on their own and may continue to grow.
At-home methods are not recommended – Attempting to drain or remove a pilar cyst at home can lead to infection, scarring, or recurrence, as the cyst sac needs to be fully removed to prevent regrowth.
Antibiotics – If a cyst becomes infected, a doctor may prescribe oral antibiotics to reduce swelling and inflammation. However, antibiotics do not remove the cyst itself.
Surgical Removal and What to Expect
For cysts that are large, painful, or infected, surgical removal is the most effective treatment. A dermatologist or surgeon can perform this quick outpatient procedure using local anaesthetic.
