Clogged hair follicles, medically termed folliculitis, is a condition that affects the scalp and skin.

It generally occurs when the hair follicles become clogged or inflamed with dead skin cells, oil and dirt. Sometimes bacterial infection also causes hair follicles to get clogged and leads to unsightly problems and other complications.

Folliculitis look like small pimples around the scalp, but the infection can spread and lead to other symptoms, too. It's important to note that if folliculitis is left untreated, it can cause severe infection on the scalp and may lead to permanent scarring and hair loss as well.

There are several ways to unclog blocked hair follicles, depending on the severity and cause of the condition. Some common treatment options may include the following:

Topical creams: Over-the-counter antifungal and antibiotic creams and ointments can be used for the treatment of fungal and bacterial infections on the scalp. They can also be applied on open sores and large nodules.

Oral medications: Oral medications like antibiotics prescribed by doctors may also reduce inflammation and other uncomfortable symptoms of clogged hair follicles. These medications can also be used to stop the infection from spreading.

Hot compress: To unclog hair follicles at home, you can even use a hot compress, and apply it to the affected area on the scalp.

Anti-dandruff shampoo: Using a dermatologically-recommended anti-dandruff shampoo can also reduce infection and inflammation on the scalp.

Laser hair removal: In some cases, doctors recommend laser hair removal to prevent risk of infection and reduce number of infected hair follicles. Hair removal treatment is also an ideal option for people with severe folliculitis infection.

How can you prevent clogged hair follicles?

To prevent folliculitis, follow these tips:

Maintain a regular hair-care routine

One of the best things you can do to prevent clogged hair follicles is to maintain a regular and safe hair-care routine.

If you have a severe infection on the scalp, avoid using styling products, especially ones that contain waxes and oils, till the scalp heals.

Check the label of the product

To prevent infection from spreading, check the labels of hair products you use. Avoid products with dimethicone and silicone. Use salicylic acid on the scalp a few times a week for exfoliation.

Don’t touch or rub your scalp

When you have folliculitis, avoid touching, scratching or rubbing your scalp, as that can cause more inflammation and trigger more irritation.


Other than these preventive tips, it's also important to maintain a healthy lifestyle and diet to keep hair follicles strong and away from infections from the inside. Keep in mind that a poor diet and lifestyle habits can contribute to severe scalp and hair issues.

While mild clogged hair follicles go away in a few days on their own or with basic remedies, serious or repeated infections require proper prescription medication. So, do not hesitate to consult a doctor in cases where symptoms are severe or persist for more than a week.
