Demodex folliculorum is a microscopic mite that naturally inhabits human hair follicles, particularly on the face and eyelashes. It is one of two species of Demodex mites found on humans, the other being Demodex brevis, which resides deeper in the sebaceous glands of hair follicles.
Demodex (Face Mites): Folliculorum, Brevis & Treatment
Life Cycle and Characteristics
Demodex folliculorum mites are tiny, measuring between 0.15 mm to 0.4 mm. They have elongated bodies and eight legs near their head. These mites feed on skin cells and can become active at night, coming to the surface of the skin to mate and lay eggs !

Symptoms and Conditions
Most people coexist with these mites without any problems. However, when their population grows excessively, it can lead to a condition called demodicosis. Symptoms of this condition include:
- Itchiness
- Redness
- Burning sensations
- Rough, sandpaper-like skin
- White sheen on the skin or eyelashes
- Eye irritation, decreased vision, and loss of eyelashes if the eyes are affected .

Risk Factors
Demodicosis is more common in individuals with weakened immune systems, such as those undergoing chemotherapy, taking immunosuppressants, or living with HIV/AIDS. It can also be associated with other skin conditions like rosacea.
Diagnosis
Diagnosis of Demodex folliculorum infestation involves dermatological tests such as dermoscopy, skin scraping, or skin biopsy to detect the mites or their eggs in the hair follicles.
Treatment
Treating demodicosis typically involves the use of acaricides, which are substances that kill mites. Common treatments include creams and lotions containing benzyl benzoate, permethrin, sulfur, crotamiton, metronidazole, salicylic acid, and ivermectin. For ocular involvement, specific treatments might involve tea tree oil or macadamia nut oil applied to the eyelashes .
Prevention and Management
Preventing an overgrowth of Demodex mites includes maintaining good facial hygiene, avoiding greasy skin products, and regular gentle exfoliation. Washing the face twice daily with a mild cleanser can help manage the mite population.
Demodex folliculorum mites affect the hair follicle primarily by residing and feeding within it. Here's a breakdown of what they do:
1. Physical Occupation and Feeding: These mites live in the hair follicles, particularly in areas with high sebum production like the face. They feed on dead skin cells, sebum, and other materials present in the follicles
2. Follicular Hyperkeratosis: Their presence can lead to hyperkeratosis, which is the thickening of the outer layer of the skin within the hair follicle. This can result in the follicles becoming clogged with an excess of dead skin cells and other debris
3. Inflammation and Immune Response: The mites' activities and their waste products can provoke an inflammatory response in the skin. This inflammation can lead to conditions like folliculitis (inflammation of the hair follicles), characterized by redness, itching, and sometimes the formation of pustules.
4. Damage to Hair Follicles: Severe infestations can cause significant damage to the hair follicles. This can manifest as hair loss, particularly noticeable on the eyelashes where the mites can cause a condition known as madarosis (loss of eyelashes) !

5. Associated Skin Conditions: Demodex folliculorum has been linked with various dermatological conditions, such as rosacea and demodicosis, due to their impact on the hair follicles and surrounding skin.

Histological Effects
Histologically, the effects include the presence of numerous mites within the follicular infundibula (upper parts of the hair follicles), hyperkeratosis, and sometimes a lymphocytic infiltrate, indicating an immune response to the mites.
In summary, Demodex folliculorum mites can cause significant disruption to hair follicles through their feeding and habitation, leading to inflammation, potential hair loss, and exacerbation of other skin conditions.
Oil production can indeed influence the colonization of Demodex folliculorum on the scalp. Here's how it works:
1. Sebum as a Food Source: Demodex mites feed on sebum, the oily substance produced by sebaceous glands within hair follicles. This makes areas of the body with high sebum production, such as the scalp, particularly conducive to their colonization.

Wikipedia](https://en.wikipedia.org/wiki/Demodex_folliculorum) [oai_citation:3,Demodex, demodicosis | DermNet](https://dermnetnz.org/topics/demodex).
2. Increased Oil Production: High levels of sebum can lead to an overgrowth of these mites. When the scalp produces excess oil, it provides more food and a more favorable environment for the mites to thrive and multiply. This can result in higher concentrations of mites in these areas.
[ Folliculorum, Brevis & Treatment](https://my.clevelandclinic.org/health/diseases/22775-demodex-face-mites) [oai_citation:5,Demodex folliculorum - Wikipedia](https://en.wikipedia.org/wiki/Demodex_folliculorum).
3. Follicular Blockage and Inflammation: Excessive oil can also contribute to the blockage of hair follicles, creating an environment where mites can proliferate. This can lead to folliculitis, characterized by inflammation and infection of the hair follicles.
4. *Conditions Aggravated by Oil*: Conditions such as seborrheic dermatitis, which involves an overproduction of sebum and can affect the scalp, might see an increased presence of Demodex mites. The mites' proliferation in response to the abundant sebum can exacerbate symptoms like itching, redness, and scaling!
Managing Oil Production
To manage and potentially reduce the colonization of Demodex mites on the scalp, consider the following:
- Regular Cleansing: Washing the scalp regularly with a mild shampoo can help reduce excess oil and remove dead skin cells, which can limit the food supply for the mites.
- Avoiding Heavy Hair Products: Using lightweight, non-comedogenic hair products can prevent further clogging of the hair follicles.
- Topical Treatments: In cases of severe infestation, medical treatments such as topical acaricides (e.g., permethrin, metronidazole, ivermectin) can be prescribed by a healthcare professional.
By managing oil production and maintaining scalp hygiene, it is possible to control the population of Demodex folliculorum and mitigate the associated symptoms.
Applying external oils to the scalp can exacerbate the proliferation of Demodex folliculorum mites. Here's why:
1. **Increased Sebum and Food Source**: External oils can add to the natural oils (sebum) produced by your scalp, providing an abundant food source for the mites. This can create a favorable environment for them to thrive and multiply!
2. Follicular Blockage: Heavy or greasy oils can block hair follicles, trapping sebum and dead skin cells inside. This blockage can create an ideal habitat for mites, leading to increased colonization and potential inflammation of the follicles!
3. Inflammation and Irritation: Oils can sometimes cause irritation or inflammation of the scalp, further compromising the skin's ability to manage mite populations effectively. This can lead to symptoms such as redness, itching, and scaling.
Recommendations for Managing Scalp Health
To manage scalp health and mitigate the proliferation of Demodex mites:
- Use Non-Comedogenic Products: Choose hair and scalp products labeled as non-comedogenic or designed for sensitive skin to avoid clogging hair follicles.
- Regular Scalp Cleansing: Wash your hair regularly with a mild shampoo to remove excess oils and dead skin cells.
- Avoid Heavy Oils: Refrain from applying heavy oils directly to the scalp. If necessary, use lightweight oils sparingly and ensure thorough cleansing afterward.
- Consider Medical Treatments: In cases of severe mite infestation, consult a healthcare provider for appropriate treatments, which may include topical acaricides like permethrin or ivermectin.
By managing the application of external oils and maintaining proper scalp hygiene, you can help control the population of Demodex mites and reduce associated symptoms.

OMG, I had absolutely no idea these types of bugs existed and what they love to feed off of. But, I’m super glad that now I do for sure. Because, i used to use heavy butters and curl creams that were chocked full oils that I thought was best to use towards styling my natural hair with hair and I also used to pre-poo with oil on my scalp and hair on my wash days, thinking that I was doing right, according to “Team Natural”, and believing all the misinformation that they have put out in YouTube videos on the internet. However, I am so happy that I stopped listening to these “natural hair influencers” guiding their viewers down th…
