Top 5 Most Effective Methods To Get Rid Of Hairline Acne

Looking for ways to overcome hairline acne? You are in the right place. Here we will discuss the most popular hairline acne treatments, their features, and precautions. And also highlight the most effective method based on scientific research.

When most people think of acne, those that appear on areas such as the chin, forehead, or back come to mind. But sometimes the rash can appear higher on the face, for example, right along the hairline. This type of acne can be just as severe as those that appear on other parts of the body.

One of the most frustrating things about acne is that it is a disease without a clear path to treatment. There are plenty of methods to overcome hairline acne, for example, taking antibiotics, applying antibacterial ointments, etc. However, a cure that is ideal for one patient may not affect another. One treatment that has shown promise for a large number of patients is light therapy.

In this article, we’ll look at the causes of hairline acne, how it is treated with scientifically proven light therapy, and how it can be prevented in the future.

Causes of acne on the hairline

Hairline acne, like any other form of acne, occurs when hair follicles (or pores) become clogged with excess sebum and debris. Debris, such as dead cells or makeup that hasn’t been washed off, usually results in pimples on some parts of the face. Hairline acne is often the result of accumulated hair products, sweat, and dirty cloth that rub against the skin’s face (for example, a headdress).

It is also worth noting that an environment favorable for the occurrence of inflammation is quickly formed in human hair due to body heat. Sweat secreted during thermoregulation of the body, together with the active work of the sebaceous glands, creates favorable conditions for the rapid growth of the number of pathogenic bacteria that cause inflammation when they penetrate the pores of the skin.

Among the accompanying factors are the following:

Hair products

Hairline acne is most often caused by clogged pores with hair products. Common pore-clogging ingredients include oils such as marula oil, flaxseed oil, avocado oil

A good rule of thumb to follow is if a product tends to clog the pores on your face, don’t assume it won’t clog the pores on or around your scalp, including your hairline.

Dirty cloth/materials

Items we wear on our heads, such as hats, headbands, scarves, or caps, can clog pores when sweat or dead cells accumulate on them, especially when it is in contact with the skin.

Also, pay attention to hairbrushes and linens. Hairline acne can be caused by contact with these objects. Unnatural (synthetic) materials in some cases provoke the appearance of inflammation. In addition, the skin can react to the presence of insects, such as dust mites, a favorite habitat for which are pillows.

Poor nutrition

Improper and irregular nutrition can lead to acne on the head. Our food tends to be too fatty and not rich in vitamins. Many of us overuse sweet, smoked foods. All this can lead to more active sebaceous glands and increase the risk of acne.

Bad habits

Bad habits (smoking, alcohol abuse) also play an important role in the appearance of hairline acne. In addition to a general weakening of immunity, they lead to the accumulation of harmful substances by the body, the state of the skin changes in a negative direction, which creates favorable conditions for the formation of inflammation.

The above list is far from exhaustive.

Hairline acne can also form due to other diseases. Therefore, if they bother you regularly, or spread over a wide area, it is worth considering a visit to a qualified specialist.

Antibiotics are often used to treat hairline acne. For example, tetracycline or erythromycin. But due to a large number of side effects, such as nausea, stomach problems (gastritis, pancreatitis), high blood pressure, dizziness, it is used strictly according to the doctor’s prescription in the dosage indicated by him.

Antibacterial ointments

Often used in tandem with antibiotics. It is recommended to apply to clean, dry skin exclusively on the acne-affected area. On average, it takes about 12 weeks to get noticeable results from ointments, which is a fairly long period. It should also be borne in mind that this method can cause skin irritation (erythema, peeling of the skin, dryness, and itching), so you should be careful with it.

Salicylic alcohol 1% or 2%

Another popular method for getting rid of acne. It should be used with extreme caution since the presence of alcohol in the composition dries the skin very much and can cause dermatitis. And if you have moles or warts on your face, you should refrain from salicylic alcohol at all, as it provokes hyperpigmentation. It must be applied pointwise and carefully, to avoid one more consequence — skin burn.

Alternative medicine

This method is used when the inflammation occupies a small area and is not accompanied by any complications. For treatment, various infusions of different herbs are used (aloe, anise, calendula, nettle). However, it is worth considering that alternative medicine has no clinically proven effectiveness, which as a result can only aggravate the existing situation.

Light therapy

An underrated, but powerful treatment for acne that ranks next to antibiotics in terms of effectiveness and has few side effects. The procedures can be performed both in the beautician’s office and at home using hand-held light devices.

Check out the SolaWave brand, which gained its popularity due to portable light therapy wands that have proven effective in combating various skin concerns, including hairline acne.

How does light therapy help hairline acne

One way to kill bacteria and get rid of acne is with light therapy. The bacteria in the skin are sensitive to certain types of light, namely red and blue.  

🔴 Red light, due to its wavelength (633-830 nm) and the ability to penetrate the layers of the skin to a depth of 4-5 mm, improves blood circulation and affects cells, thereby saturating them with oxygen and nutrients. Red light helps reduce inflammatory conditions such as acne, fights blackheads, and minimizes acne scars.

If acne is caused by a chronic skin condition, red light therapy is a good option for you.

More detailed information about red light therapy in acne treatment, its effect on the skin, and the effectiveness of its use, confirmed by numerous scientific studies in our article.

🔵 Blue light emits short wavelengths (400-510 nm) and is close to ultraviolet in the spectrum of waves, which gives it the same antibacterial properties but does not expose the skin to additional risk. It penetrates only into the uppermost layers of the skin (by 1 mm), but this is enough to saturate the skin with oxygen, which leads the bacteria propionibacterium acne to their death. It is also reported that blue light allows the condition to be monitored before new acne breaks out.

When you shine the rays of these lights on your skin, substances are formed that kill bacteria. Light therapy also shrinks the sebaceous glands in the skin, so less oil is produced in the skin that clogs pores.

The effectiveness of light therapy in treating hairline acne based on clinical trials

Over the past decade, light therapy has become a common treatment for a wide range of skin conditions, including acne. Despite various oral and topical treatments for acne, many patients do not respond well or may develop side effects. Thus, patients are experiencing a growing demand for new therapies that are fast, safe, and free of side effects.

Below we have provided the results of some studies that support the effectiveness of light therapy in treating acne.

In a study [1], 28 patients with mild to moderate acne were treated with handheld devices emitting red light. Phototherapy was performed for 15 minutes twice a day for 8 weeks. As a result, the improvement in the number of non-inflammatory and inflammatory lesions was about 70%. Visually, rashes with acne decreased by 1,5 times.

The next study [2] was involving 24 patients with mild to severe acne. They were treated with light therapy for 8 sessions, twice a week at intervals of 3 days.

As a result, a decrease in the number of lesions was observed in all patients. At the 4-week follow-up, the average decrease in the number of lesions was 46%, and at the 12-week result, it was even more impressive 81%. Severe acne showed slightly better results than mild acne. Side effects were minimal and only included redness.

Recently, phototherapy has been used with different light spectra for acne.

In this study [3], two different wavelengths (630 and 890 nm) were evaluated for the treatment of acne vulgaris. 28 patients with mild to moderate acne were treated with red light therapy (630 nm) and infrared (890 nm) on the right and left sides of the face, respectively, twice a week for 12 sessions. As a result, after 10 weeks of the treatment, acne was significantly reduced on the side treated with red light (630 nm), in contrast to the area treated with infrared light (890 nm).

A combination of red and blue light is often used to treat acne, which has a proven antimicrobial effect. Below is an example of a study that shows the effectiveness of this treatment.

A study [4] involved 24 patients with mild to moderate facial acne; they were treated with LED devices with alternating blue (415 nm) and red (633 nm) light. The treatment was carried out twice a week for 4 weeks.

The final mean percentage improvement in non-inflammatory and inflammatory lesions was 34.28% and 77.93%, respectively. The measurements showed that the melanin levels decreased significantly after treatment, which was reflected in the improvement in the skin texture of the patients.

Based on the research, it can be concluded that light therapy is a safe and effective treatment for mild to moderate inflammatory acne. Although comparable to the effects of antibiotics, acne relief with light therapy offers faster resolution and fewer side effects, resulting in patient satisfaction.

How to prevent hairline acne

There are some steps you can take to prevent future hairline acne. These steps include the following:

  • Keep sheets and pillowcases clean to prevent oil and bacteria accumulation.
  • If you wear hats, wash them after two or three uses, especially if sweat has accumulated on them during the day.
  • Use skin care products and cosmetics that won’t clog your pores — look for “non-comedogenic” ingredients.
  • When applying hair or skin care products, make sure your hands are clean and touch your face as little as possible.
  • If you have bangs, do not touch them so that bacteria and dirt do not get from your fingers to your hair and forehead.
  • Eat a complete diet and exercise regularly, including showering after exercise.
  • Try to monitor the immune system, take vitamins as needed, and avoid hypothermia.

Following these simple tips will help keep your risk of acne recurring to a minimum.
