How does lurbinectedin impact hair follicle development?

Lurbinectedin’s direct effect on hair follicle development has not been studied in humans.

How does lurbinectedin cause hair loss?
The drug damages rapidly dividing cells, including those in the hair matrix that produce the hair shaft, which leads to hair thinning or complete loss during treatment.

When does hair loss begin and how long does it last?
Hair shedding typically starts two to three weeks after the first dose and continues through the treatment period. Regrowth usually begins two to four months after therapy ends, although texture or color may differ.

What makes lurbinectedin different from other chemotherapies that cause hair loss?
Lurbinectedin is a selective inhibitor of oncogenic transcription that spares some normal tissues better than older agents, yet hair follicle cells remain vulnerable because they divide quickly.

Can anything prevent or reduce hair loss with lurbinectedin?
Scalp cooling devices have shown modest benefit in small studies, but no approved preventive treatment exists. Patients are advised to use gentle hair-care routines and protective head coverings.
