In this article, we discuss everything – from the causes and precautions, to what exactly one should do to heal pimples on the scalp effectively.

 

1. Causes of pimples on the scalp

Frequently asked questions about pimples on the scalp

Finding out about the various causes of pimples on the scalp gives you a better understanding of this condition and makes treating it a lot simpler. The main reason behind the occurrence of scalp acne is the clogging of follicles, which can be caused by dirt, bacteria or oil. Let’s look at these causes in detail -

i) Hair oiling –

“This is the most common cause of pimples on the scalp,” says Dr. Soma Sarkar. “The scalp is rich in sebaceous glands and the natural sebum secretion is enough to lubricate scalp and hair. Oily hair becomes a rich medium for dandruff to grow in that area and this gives rise to acne on the scalp,” she concludes.

ii) Scalp folliculitis –

This is a condition where there is inflammation of the hair follicles and the natural host bacteria feed on the excess sebum. This can also give rise to pustular lesions on the scalp,” explains Dr. Sarkar

iii) Seborrheic dermatitis

This is another common cause of pimples on the scalp according to Dr. Sarkar. In this condition, you’d notice greasy, scaling skin and acne-like eruptions on the scalp. More commonly known as dandruff, the white or yellow-ish flakes on your scalp can end up clogging your pores, resulting in breakouts and pimples on the scalp.

iv) Lack of personal hygiene

If you are someone who is lazy about washing your hair and avoid shampooing for a long time, then this could be the reason behind the cause of scalp acne. The sweat, oil, dirt and pollutants, all end up settling on your scalp, and end up clogging your pores over time. This could give rise to scalp acne.

v) Product build-up –

A lot of times, there is a build-up of hair care products on your scalp, which clogs follicles and irritates your scalp, giving rise to pimples on the scalp. It is important to rinse away your hair care products thoroughly, as well as use a clarifying shampoo once in two weeks to get rid of product and dead skin build-up thoroughly.

vi) Acne keloidalis nuchae –

Dr. Sarkar says, “This is a rare condition that causes pimples, usually on the hairline and nape of the neck, and is another rare but definite cause of pimples on the scalp.”

For this condition to completely be resolved, it may take a while, depending on a number of factors such as the type of scalp, severity of the condition, response to treatment, etc.,” explains Dr. Sarkar.
