Human sebum is a combination of lipids (including triglycerides, fatty acids, cholesterol, and more). Sebum is produced in the hair follicle; Lubricates the hair follicle and spreads over the scalp (and skin) to prevent moisture loss.
Excess sebum production makes hair and skin oily and can lead to various complications such as dandruff and acne. If left untreated, sebum buildup on the scalp can cause more serious symptoms and complications, including hair loss.
Learn more about the causes of sebum buildup and how to treat it.
What is scalp extension?
Hyperseborrhea (increased sebum production) is one of several causes of congestion of the scalp. Scalp growth is an accumulation of:
- Dead skin cells
- Hair products
Similarities to other scalp conditions
The symptoms of hyperseborrhea often resemble other scalp conditions such as dandruff, scalp eczema, and scalp psoriasis.
Symptoms of a scalp congestion include:
- Flaky scalp
- Oily or crusty skin (called crib in babies)
- Sin redness on the scalp.
- Itchy scalp
Causes of scalp growth
The exact cause of the underlying factors that lead to sebum accumulation, such as hyperseborrhea, is unknown, but certain factors can increase the likelihood that a person will have increased sebum production and accumulation, for example:
- Hormonal imbalance : An imbalance in the production of thyroid and pituitary hormones is believed to lead to an increase in sebum production .
- Metabolic disorders : A diet rich in unhealthy fats (such as saturated fats) affects the overall metabolic activity of the body. This leads to increased sebum production, which causes hyperseborrhea. In turn, hyperseborrhea is the main factor that contributes to the growth of the scalp.
- Digestive Problems: Intestinal and liver problems can alter the chemistry of sebum, rendering it ineffective at protecting hair and scalp.
- Poor scalp hygiene – This can lead to various scalp problems. The frequency of hair washing, the products used and other factors can cause an imbalance in the accumulation of sebum and the scalp.
- Washing your hair infrequently (less than every two to three days) : This can cause congestion of the scalp and lead to inflammation. This can slow down the normal hair growth process.
- Microorganisms : A buildup of bacteria or fungi can cause inflammation of the scalp, which can be the main cause of scalp congestion. A pathogenic (disease-causing) organism called Demodex folliculorum is found in hair follicles that are infected with a parasite; This changes the composition of the sebum, resulting in hyperseborrhea.
Complications from prolonged build-up of sebum on the scalp can include:
- Hair loss (due to a condition called folliculitis, in which the hair follicles are damaged)
- Acne (around the hairline)
- Steatoid versicolor (oily dandruff)
- Seborrheic dermatitis
How to get rid of scalp growth
There are several home remedies to get rid of scalp congestion. This includes:
- Regular and thorough shampooing : should be done every two or three days (usually for very oily hair). with a natural, mild sulfate- and chemical-free shampoo that suits your hair type (eg, oily, dry, etc.). When shampooing, use warm (not hot) water, as hot water can worsen scalp conditions and worsen symptoms, drying out the scalp and increasing flaking and itchiness. Avoid excessive scratching and vigorously rubbing back and forth from the scalp. It is best to massage the scalp in light circular motions to improve blood flow and prevent dry scalp.
- Apple Cider Vinegar Rinse : Apple cider vinegar has been found to have antimicrobial (antibacterial and antifungal) properties, killing and preventing the yeast that causes dandruff on the scalp. Gargling with apple cider vinegar once a week can also help remove hair product build-up.
- Brush your hair : It is important to maintain a well-groomed appearance of your hair, but avoid vigorous brushing, which can worsen sebum build-up on the scalp.
- Use lemongrass essential oil ( Cymbopogon flexuosus ) : A hair tonic formulation with 10% lemongrass oil has been shown to be effective in reducing dandruff.
- Exfoliate your scalp : Do this once or twice a week with a regular scalp scrub (or a homemade natural scrub made from oatmeal, brown sugar, and hair conditioner) to remove dead skin flakes and clumps from the scalp. Keep in mind that exfoliating your scalp more frequently (once or twice a week) can lead to increased sebum production. Therefore, it is important not to exfoliate your skin too often.
Preventing sebum and sebum build-up includes home remedies such as:
- Avoid overuse of hair products (such as styling products) to prevent hair build-up.
- Avoid using harsh chemicals on the scalp (including perms and hair dyes or bleaches).
- Check your scalp regularly for symptoms such as red skin, scales, and oily patches.
- Wash your hair regularly (including exfoliating and rinsing with vinegar) and be sure to wash your hair after excessive sweating (such as after running or exercising).
When to contact a healthcare provider
Call your doctor if your scalp congestion symptoms do not respond to self-medication (such as exfoliating, gargling with vinegar, or using an anti-dandruff shampoo for complications of scalp build-up). Consult your healthcare professional if an area of the scalp affected by accumulation and excessive amounts of sebum begins to:
- Become painful
- Form scabs
- Draining fluid or pus
Excess sebum production can cause congestion on the scalp. If left untreated, it can cause more serious symptoms and complications, including hair loss.
Washing your hair regularly and avoiding irritants like hair dyes are key factors in preventing scalp formation. If you have a scalp buildup that persists, see your doctor.
