Dwindling hair, brittle nails

Hair and nail diseases are common. And in many cases it is easily treatable. Early clarification of the cause is crucial.

Medically, hair and nails are skin appendages; nature intended them as protection. Magnificent hair is also a sign of beauty, strength and attractiveness, and hair has an eminent influence on a person’s appearance. Because hair and nails are clearly visible, changes in their condition are quickly noticed. And these are not uncommon. “The most common changes concern the hair and the amount of hair: there are too many or too few,” explains Thomas Kündig, Director of the Dermatology Clinic at the USZ. Every day, 20 to 30 patients come to the consultation for this reason.

No time to lose when losing hair

Thomas Kündig advises that a dermatologist should quickly clarify whether there is an underlying disease. Because as often as hair problems occur, it is reassuring that in the vast majority of cases the cause can be found quickly and effective treatment is available. “There is no scientific evidence for the influence of dietary changes and special diets, or for many non-medical therapies for hair and nail problems,” explains Thomas Kündig. “Attempts to do so only prolong the period of suffering and, in the worst case, hair is also irretrievably lost until effective treatment by specialists.”

Two types of hair loss

It is therefore particularly important to clarify the causes of hair loss quickly. A distinction is made between two forms: non-scarring hair loss, in which hair growth is restored, and scarring hair loss, in which the hair roots are destroyed and the hair is permanently lost. Scarring hair loss can usually be stopped; the earlier this happens, the more hair is retained. Non-scarring hair loss includes, for example, circular hair loss. This can usually also be treated well. Hair loss can be caused by immune disorders, bacterial diseases, fungal diseases or a malfunction of the thyroid gland. However, iron deficiency, medication or chemotherapy can also lead to hair loss.

The cause is usually found

The most common reason for consulting a doctor is the loss of hair with increasing age, known as androgenetic hair loss, which occurs in both men and women. “There are also effective ways to combat this,” says Thomas Kündig. However, these must be taken as medication without interruption, while others must be applied to the scalp twice a day as a tincture. And: Patients have to bear the treatment costs themselves, as this form of reduced hair growth is not classified as a disease by health insurance companies. For many, however, the hair loss is so serious that they are willing to put up with the effort, possible side effects and costs.

The cause of nail diseases is also found in most cases. “They are often a side effect of other skin diseases such as lichen ruber or a malfunction of the thyroid gland. But chemotherapy and certain medications can also affect the nails.” Here too, Thomas Kündig believes it is important to have the problem assessed quickly by a dermatologist, because: “We can help effectively and quickly in almost all cases.”

PRP treatment (autologous blood therapy) for hair loss

In platelet-rich plasma (PRP) therapy, the body’s own blood platelets are concentrated in an innovative therapeutic procedure and used to stimulate hair growth.
