Anti-dandruff shampoo causes hair loss

Dandruff: when there is a risk of hair loss with dandruff

You don't always see them, but everyone has them - dandruff. Usually the white flakes are so tiny that you won't notice them. But sometimes they stand out unattractively on the shirt collar or can be seen in the hair. "About 20 percent of Germans suffer from this hair problem," says dermatologist Dr. Martin Miehe. What many of those affected do not know: The drizzle is not only embarrassing and annoying, but dandruff can also be the cause of a serious illness.

Men have more dandruff

Visible dandruff is often a problem for men, women are less affected by the drizzle. "Androgens, the male sex hormones, can stimulate sebum production, the excess fat combines with dead skin cells to form large scales," explains the dermatologist. If the scalp itches, is reddened or has crusts formed, you should definitely see a doctor and have the cause clarified. Because if the hair problem remains untreated, there is a risk of hair loss in the worst case.

Too much sebum promotes dandruff

"The most common cause of excessive dandruff is seborrheic eczema, around five percent of Germans suffer from it," says Miehe. The cause of this skin disease is the yeast Malassezia furfur. It is also found on the healthy scalp, where it feeds on fats from the sebum glands. If too much sebum is produced on the head, for example due to a metabolic disorder, the fungus multiplies and the scalp sheds more dead cells. The result: For most of those affected, large, oily flakes form and the scalp itches. But even small scales, which many consider normal, can indicate seborrheic eczema.

Psoriasis and neurodermatitis make the skin rough

Another cause of the drizzle is psoriasis. "You can recognize this benign skin disease on the scalp by the silver-white scales and red and itchy areas of the skin," the dermatologist knows. In addition, the skin change is visible beyond the hairline and can also occur in other parts of the body. Atopic dermatitis can also trigger dandruff. So-called atopic eczema is a chronic inflammation of the skin that occurs in around three percent of adults. Dandruff builds up because the skin lacks certain fats. This dries it out and makes it rough.

Counselor - Hair loss can have many reasons

Contact allergies and fungal infections are rare

"A fungal attack can also trigger dandruff, but this happens relatively rarely," says Miehe. Fungi, such as the microsporia pathogen, can multiply easily, especially in people with a weak immune system. It is transmitted from person to person as well as from animal to person - for example from dogs or cats. The pathogens not only affect the scalp, they can infect the whole body. If this is the case, however, you will not only have dandruff, but also itchy rashes. Dandruff that forms after dyeing or washing your hair is most often an allergic reaction to the shampoo or tint. "Compared to the other causes of dandruff, such contact allergies are less common," says the dermatologist.

Dandruff can be treated well

Dandruff doesn't go away on its own. External treatment is often enough to get rid of them. "For seborrheic dermatitis, antifungal agents with ketoconazole and bifonazole help. The shampoos are available in pharmacies," advises Miehe. In general, flaky hair should only be washed with a mild shampoo for dry hair or a baby shampoo. It is also important that those affected do not wash their hair every day and that the water and blow dryer air are not too hot. In addition, shampoo residues should be rinsed out with clear water and the hair should not be rubbed dry. Hard brushes and combs should also be avoided because they scratch the scalp and risk inflammation and even more dandruff.
