Hair loss is a common side effect of cancer treatment and can be psychologically distressing.
As a result, many patients choose to try various solutions on their own to restore hair growth.
One of the most commonly used supplements is biotin, a vitamin found in everyday foods, and deficiency is rare.
Nevertheless, many people take it as a supplement, often based on advice from the internet or acquaintances.

Issues with tests
Research from Ohio State University, published in JCO Oncology Practice, shows that biotin can affect blood tests.
This includes tests used to monitor the progression of several types of cancer.
Biotin can interfere with measurements, making results misleading. Some values may appear lower than they actually are, while others may appear higher.

This can lead doctors to make decisions based on incorrect information or to delay treatment.
There are also indications that biotin may affect measurements used when heart problems are suspected, making it more difficult to establish an accurate diagnosis.
Better alternatives
Researchers point out that there are safer ways to manage hair loss. One example is the drug minoxidil, which is approved and used to promote hair growth.
At the same time, researchers emphasize the importance of patients consulting their doctor before starting dietary supplements.
