Seborrheic dermatitis on the scalp
This is a chronic disease in which scales appear on the skin. Its origin is unknown. It affects 2.5% of the population, mainly men.
The pharmacological treatments that exist are focused on treating the itchiness, the scaling and redness.
Seborrheic dermatitis affects the zones with more sebaceous glands: the scalp, the area behind the ears, the creases of the nose, the eyelids and the chest. And, less frequently, it affects the area of the belly button, the surface creases on the arms, the groin and the armpits.
When dermatitis affects the scalp, it could lead to hair loss. We would like to explain this situation below:
Each hair rests on a hair follicle and within each hair follicle, there are sebaceous glands. In the people that suffer from seborrheic dermatitis, the sebaceous glands are more active and therefore they produce more grease. This excessive grease asphyxiates the hair follicles and therefore decreases the oxygen-intake of the hair. The hair which receives little oxygen gets weaker and falls.
Among other factors, the triggers of seborrheic dermatitis are the following:
- Genetic factors
- The climate: Seborrheic dermatitis is more frequent in summer
- A diet based on carbohydrates
- Sedentary lifestyle
- In children, a deficiency of biotin (or vitamin H, which is necessary for the health of hair and nails)
- Emotional exhaustion can aggravate the disease
- Shampoos that are excessively degreasing (they can trigger a rebound effect)
Apart from pharmacological treatments (anti-inflammatory, anti-fungal and antimicrobial products or the use of vitamin A equivalents), a balanced diet low in fats and carbohydrates and rich in biotin is recommended.
To sum up, we are providing you with a list of nutritions that are rich in biotin that could be beneficial to soothe the symptoms of dermatitis as long as they are taken in moderation:
Food of animal origin:
- Non-fatty meat, egg yolk, fatty fish.
Food of vegetable origin:
- Legumes: soy, peas, chickpeas.
- Cereals: oats in grain, barley.
- Vegetables: garlic, tomatoes, watercress.
- Shiitake Mushrooms.
- Fruits: avocados, bananas, apples, grapes.
- Dried fruits: walnuts, peanuts.
