Why is my husband’s pillow so oily?

The greasiness of my husband's pillow is related to the strong secretion of scalp oil. The main reasons include the influence of male hormones, bad living habits, scalp inflammatory reaction, improper cleaning methods and genetic factors.

1. Hormone levels:

Testosterone and other male hormones in men stimulate the sebaceous glands to secrete oil, and secretion is particularly strong from adolescence to middle age. Fluctuating hormone levels can cause pillowcases to quickly accumulate oil during sleep exposure, resulting in visible stains. This type of physiological oil production is usually accompanied by symptoms such as flat hair and oily T-zone on the face.

2. Living habits:

Staying up late for a long time and eating a high-fat diet will increase sebum secretion. The period from 23:00 to 3:00 in the morning is the peak period of skin metabolism, and disordered work and rest will lead to imbalance of oil regulation. The pro-inflammatory factors in spicy fried foods may affect the function of sebaceous glands through intestinal flora, leaving more oily substances on pillows.

3. Scalp problems:

Conditions such as seborrheic dermatitis or folliculitis can cause abnormal oil production, often accompanied by symptoms such as increased dandruff and itching. Excessive growth of Malassezia will break down sebum and produce free fatty acids, which not only increases the greasiness, but may also cause pillows to turn yellow. In this case, fungal reproduction needs to be controlled with drugs such as ketoconazole lotion.

4. Improper cleaning:

Shampooing your hair too infrequently or cleansing it too much can damage your scalp barrier. Cleansing less than three times a week will lead to oil accumulation, and powerful oil removal products containing SLS surfactants may stimulate the sebaceous glands to secrete more oil compensatoryly. It is recommended to choose an amino acid-based mild shampoo and control the water temperature below 38°C.

5. Genetic constitution:

Sebaceous gland number and activity are significantly affected by genes. If there are members with oily skin in the family, the probability of offspring having oily pillows is higher. People with this type of constitution usually have thicker sebaceous gland ducts on the scalp, and the oil secreted by them is more likely to transfer to the surface of bedding to form oil spots.

To improve the oiliness of pillows, we need to start from multiple aspects: ensure 7 hours of sleep every day to help regulate hormone rhythms, and increase the intake of foods rich in B vitamins and Omega-3 such as oats and deep-sea fish.； Choose breathable pillowcases made of bamboo fiber or Tencel, change them at least twice a week and wash them at a temperature above 60°C. ； Carry out regular scalp exfoliation conditioning to avoid barrier damage caused by nail scratching. If it is accompanied by symptoms such as redness, swelling, hair loss, etc., it is recommended to go to a dermatology department for fungal microscopy or hormone level testing.
