The validity of over-the-counter skin, hair, and nail recommendations for adult patients with cancer: A systematic review.

Importance: Patients undergoing cancer treatment experience a multitude of skin, hair, and nail adverse events, prompting them to use non-evidence-based and often restrictive over-the-counter (OTC) recommendations to alleviate their symptoms. Comprehensively assessing evidence-based OTC modalities is crucial to enable cancer patients to comfortably resume their lives post-treatment and integrate clinically sound practices into their self-care routines.

Objective: Perform a systematic review and assessment of evidence-based OTC skin, hair, and nail care recommendations for adult patients undergoing cancer treatment.
