Based on the information provided, I was unable to find a specific duration for how long lurbinectedin hair loss lasts. However, I can provide some context about the drug and its potential side effects.

Lurbinectedin is an antineoplastic agent, a type of drug used in cancer treatment. It works by inhibiting the transcriptional activity of oncogenic fusion proteins, which can lead to the death of cancer cells [1]. The drug is currently in clinical trials for various types of cancer, such as small cell lung cancer and ovarian cancer [1].

Hair loss, also known as alopecia, is a possible side effect of many chemotherapies, including lurbinectedin [2]. The duration of hair loss can vary depending on several factors, such as the individual's health, the dosage, and the length of treatment [3]. In general, hair loss from chemotherapy is temporary and new hair growth usually begins a few weeks to a few months after the end of treatment [3].

For more specific information about lurbinectedin and its side effects, it is recommended to consult the drug's prescribing information or consult with a healthcare professional [2].
