Clogged hair follicles cause pimples on your scalp (scalp acne). Your hair follicles are the canals where your hair grows out of your skin. They could be clogged due to: A buildup of hair products like shampoo, hair gel or hairspray.
Pimples on the scalp occur when a pore or hair follicle gets clogged with dead skin cells or sebum. Bacteria, yeast, or mites can also get into the pores and cause a reaction. Factors that can cause scalp acne include: dead skin cells or oil clogging the follicles.
The rash appears as small red bumps or pus bumps that can itch or be mildly painful. Folliculitis is common on the buttocks, arms and legs - especially the thighs. Most improve in 7 to 10 days. Sometimes after the rash is gone, dark marks can be left behind.
Scalp folliculitis usually looks like clusters of small red bumps and can initially be mistaken for an acne breakout.
Bacterial folliculitis.
This common type is a rash of itchy, pus-filled bumps. It occurs when hair follicles become infected with bacteria, usually Staphylococcus aureus (staph).
There can be several causes for scabs on the scalp - from dandruff and lice to contact dermatitis and seborrheic eczema. Depending on the cause, treatment can be chosen. Most times, the scabs clear up with topical treatments or targeted medication.

What is a pilar cyst? Pilar cysts are relatively rare noncancerous (benign) cysts that grow from your hair follicles. Most pilar (pronounced pīlər) cysts surface on your scalp (head), but they can appear on your face, neck, arms and legs. Pilar cysts are sometimes called trichilemmal cysts or wens.
A person may have more than one pilar cyst at a time, and they may disappear and return. In most cases, a cyst will cause no symptoms and will heal without treatment. If necessary, a doctor will remove a cyst with a simple procedure. The cyst may reappear in the same location, and new cysts may develop in the future.
Signs & Symptoms
Pilar cysts are usually found on the scalp. They appear as smooth, movable bumps under the skin. There is often more than one in an area, and they may become quite large.
To prevent infection and potential scarring, avoid: Squeezing the cyst. Attempting to “pop” it and drain the liquid.
Popping a cyst on your own is highly inadvisable. First of all, the pilar cyst has thick skin which makes it difficult to pop without any cut. If you try to pop the cyst using your nails or any other sharp objects, you may end up injuring the skin. It will lead to severe infection and pain.
Cysts on the scalp are so prevalent that they have their own name: pilar cysts. However, they are typically treatable and not dangerous. The same holds for other cysts that can form on your scalp, such as epidermal, trichilemmal and sebaceous cysts. If you are lucky, your cyst might naturally disappear.
A trichilemmal cyst, also known as a pilar cyst, is a keratin-filled cyst that originates from the outer hair root sheath. Keratin is the protein that makes up hair and nails. Trichilemmal cysts are most commonly found on the scalp and are usually diagnosed in middle-aged females.
If your cyst isn't bothering you, you can monitor it for a couple of weeks to see if it will disappear naturally. But if it's painful when you brush your hair, it's not getting smaller, or it's recurrent, don't hesitate to talk to our team at LUX Dermatology.
Pilar cysts are filled with keratin and originate from the outer hair root sheath or hair follicle. These cysts are commonly found on the scalp and around the hairline, and they can resemble epidermal cysts in appearance and size. Pilar cysts tend to run in families and are usually non-cancerous.
Sebaceous Cyst Removal, also know as Sebaceous Cyst Excision
They appear primarily on the face, back, lower neck or base of the ears, or anywhere else on the body. Pilar cysts (trichilemmal cysts) resemble epidermoid cysts as they are firm, slow-growing subcutaneous nodules.
There is no right or wrong answer for pilar cysts. Some patients live with them if they don't cause issue. Others get them removed if they are tending to become inflamed or infected or carry a risk of temporary or permanent hair loss.
Pilar cysts, also trichilemmal cysts, are common dermal cysts. They occur in less than 10 percent of the population but are the most common type of skin cyst. They mostly affect the skin of the scalp.
