One morning, you look in the mirror and notice a small bump that develops on your chin, which contains a figure of a hair inside. If this case happens, you are likely to have an ingrown hair cyst – a common skin disorder in people who have bad hair removal routines.

So, what causes ingrown hair on face and other parts of the body? And how to get rid of ingrown hair?

This article will explain everything you need to know about this skin issue and the most effective way to help you get rid of a bad ingrown hair.

What is an ingrown hair cyst?

Despite it does not sound familiar to many of us, an ingrown hair cyst is a common condition of our skin. It refers to a cyst which forms inside the hair follicle deep underneath the skin. Some people often misunderstand it as the combination of a cyst and an ingrown hair, but it is actually an independent condition.

The cysts usually appear in people who shave or wax too regularly. Most of us try to get rid of them because of their unpleasant appearance, but a wrong method can worsen the situation and lead to cyst infection.

With a team of clinical practice experts, we will provide the detailed information about the cause, treatment, and prevention of ingrown hair cyst.

What causes ingrown hair in your body?

There are two main reasons of ingrown hair cyst, but it usually appears after a bad method to remove your hair [1].

Skin irritation

Using improper devices (or shaving, waxing, and tweezing violently) to cut the hair can irritate your skin deep layers. The bacteria on the skin or from the outside can enter the damaged area and cause inflammation inside the hair follicles. There it forms ingrown hair pimple and cysts at the root of your hair.

Wrong direction of hair growth

The natural structure of the hairs follicles supposed to be straight, but sometimes it appears in a curvy figure. These types of follicles produce tightly curled hair. After you shave your hair, especially in a dry condition, it tends to bend and re-enter the skin when growing.

Our body responds to the foreign agents by creating a local inflammation – which is the start of ingrown hair cyst. Sometimes, the reaction of the immune system to these cysts make us misunderstand with other types of acne because they look similar.

Here are some potential risk factors of ingrown hairs:

  • You have a natural tightly curled hair
  • Your skin is dry
  • You are infected by bacteria or fungus
  • Wear tight clothes
  • Use improper skin care products

How to differentiate ingrown hair cyst from other similar diseases?

In some cases, the problem of ingrown hair is more severe as it may be misunderstood with other skin disorders.

Acne vulgaris

If you notice the cysts getting bigger, plus with bumps in other areas of your face, it seems that you have encountered Acne vulgaris [2]. The inflamed pores create a skin cover the whole content that blocks the hair follicles, prevent it from draining and form a cyst at that position.

The ingrown hair on face is usually misunderstood with Acne vulgaris, as the symptoms are quite similar. Besides, the cysts in Acne vulgaris often present on the face and neck. If you squeeze or using improper methods to remove them, it can aggravate the complexion. Thus, looking for a consultation from your doctor or dermatologist is the best recommendation in this case.

Epidermoid cyst

This type of cyst is likely to appear in some parts of the body that have little hair. They start from the ectodermal tissues and create small bumps that have no connection with the hair follicle. However, people usually differentiate these two skin disorders.

An Epidermoid cyst is benign, but in some rare cases, it can turn into a malignant one possibly [3]. Until now, the proper treatment consists of an excision or piercing combines with antibacterial medicines.


If you are a woman, and the ingrown hair cyst is the result of the excess hair growth in abnormal positions (such as your upper lip, chin, or chest), you may acquire hirsutism [4].

This skin disorder is associated with a gene or hormonal disorder. Sometimes using medications that affect your hormonal levels (ex. steroids, danazol, and minoxidil) can lead to unwanted hair growth.

For the most accurate treatment, you need to see a medical practitioner and ask for advice.

Here is one of the most common pictures of cysts to help you distinguish between other skin problems:

What is the ingrown hair symptom?

Knowing the symptoms of ingrown hair cyst is essential as you can distinguish it with other severe skin conditions.

As the name implies, a cyst is formed after an ingrown hair appears inside the follicle. Firstly, you may notice it as a little bump with a hair across its red surface. The ingrown hair bumps become larger days by days, and the hair is still there without growing out, which makes you feel pain. The initial red color may turn into white or yellow due to the ingrown hair pus inside. If the fluid becomes green, the infection is more severe as a particular type of bacteria that called Pseudomonas aeruginosa might enter the damage.

In case there is a deep ingrown hair, it is even impossible to see the figure of the hair because it lays deeply underneath the skin layers. You can just feel the appearance of a red pimple on the surface of your skin.

Other signs and symptoms include:

  • Itching at the affected area
  • Papules and pustules
  • The skin color becomes dark
  • Visible embedded hair

When the cyst bursts itself or after an intended popping, you may see a yellow or clear discharge coming out. Sometimes, blood is included inside the cyst. Bleeding ingrown hair cyst requires a proper treatment quickly, or it will get infected.

How many types of ingrown hairs?

A curled hair can grow in two different ways:

  • The hair comes out from the skin surface without any obstructions but then pierces back into the skin.
  • The hair cannot find any exits from the follicle; it is trapped entirely under the skin. It continues to lengthen inside the pore.

Other risk factors (ex. genetics and lifestyle) can play a role in the severity of the condition.

Where can you get ingrown hair cyst?

In males, the appearance of ingrown hair cyst is usually in the beard area (ex. cyst on the jawline, cheeks, and upper lip). If you shave your head, they can develop on the scalp, too. Meanwhile, in the woman, the most common positions are ingrown pubic hair cyst and ingrown hair on leg because they tend to shave the hair on those areas.

In general, people who have tightly curly hair are more likely to have ingrown hairs than others.

There are several positions that can develop this kind of hairs, such as:

  • Ingrown hair on buttock
  • Ingrown hairs on chin
  • Ingrown hair on inner thigh
  • Ingrown eyebrow hair

The complications of ingrown hair cyst

Diagnosing and finding a suitable method to get rid of this issue is possible. But if it is left untreated, the chronic condition will become more complicated, for instance:

  • Infected ingrown hair caused by bursting or popping
  • Hyper-pigmentation (a super pigmentation on the skin)
  • Temporary or permanent scar
  • Razor bumps (caused by improper shaving)

Those complications need a longer treatment period as well as medications.

The treatment of ingrown hair cyst

What to prepare before seeing a doctor

As mentioned above, your doctor will help you find the most suitable way to solve your ingrown hair issue or send you to an expert if he/she cannot handle the problem. But before the appointment, there are some things that you need to pay attention to:

  • List every sign and symptom you are encountering, as detail as possible, even they seem unrelated to your present problem.
  • Think about your personal habits, such as shaving or waxing recently.
  • Think whether you have changed your diet or hygiene products.
  • List every medication and supplement you are taking now.
  • Prepare some questions that you want to ask your doctor.

One day before the appointment, it is better if you stop using chemical products on the affected area not to worsen the situation. Besides, you need to stop shaving, tweezing, and waxing your hair until the ingrown hair symptom alleviated.

Your doctor will be easier to make an accurate diagnosis of ingrown hair cyst by checking the symptoms and discussing your skincare routines.

Here are some medications and methods that your doctors may indicate:


In other words, it means using some devices or unique skin products to remove the upper layers of the skin, thus let the hair follicles or pores free. There are plenty of ways to get rid of dead skin cells, but they all belong to two major kinds below:


Reduce inflammation

The areas around the bumps often swell, become red, and painful when touching. Those are signs of skin infections. In these cases, your doctor will indicate cream that contains anti-inflammation agents to reduce the redness and swelling.

Steroids are the most well-known medications to get rid of the symptoms. However, it will not target at the root of the problem but just ease the complications, so abusing this method is not recommended.

Antibiotic drugs

In case you scratch the affected areas accidentally, the skin infections may occur from mild to severe level. An antibiotic ointment is essential for the local treatment, while the oral form is prescribed in moderate and over ingrown hair infections.

How to remove ingrown hair by yourself?


Yes, if the situation is not too complicated, you can totally handle the uncomfortable hairs at home by using a pair of tweezers and some supported products. We will show you how to do it in some simple steps below:

Step 1

Wash your hands with soap carefully and pour the sterilized liquid into your palm as well as the affected area.

Step 2

If the hair grows underneath the skin, it will be more difficult to remove than another that reveals itself. Use a pair of tweezers to extract the tip of the hair (if available). Do not use any sharp items to create a microsurgery, or you are at risk of skin infection.

If you cannot see the tip, use the tweezers or a needle to pull the tip out, then cut the hair off. It is not essential to remove the whole strain.

Step 3

Wash the affected area with a cleanser that contains anti-bacterial compound (you can use essential oils that have similar effects – we will mention later). Then followed with a cold rinse to close the pores.

Step 4

Pat dry using a clean towel, then apply lotion or ingrown hair cream on your skin. An ingrown hair serum is a smart choice at this time.

Home remedies for ingrown hair treatment

Other methods

Choose a gentle cleanser for your skin. Please remember, your skin is a natural barrier to protect yourself from bacteria and other harmful factors, so you need to treat it well. It is better to stay away from harsh cleansers (ex. products that contain alkaline soap or alcohol).

Most dermatologist experts recommend removing dead skin cells and dirt on the skin every week. This step will reduce the chances of clogging pores and accelerate the wound healing if ingrown hair cysts are available.

Last but not least, whatever method you choose, remember to follow up the hair removal by a gentle skin care or lotion to ease your skin.
