In this study, a combination of irinotecan and cetuximab showed varied response rates in metastatic colorectal cancer patients, with manageable skin toxicity that improved quality of life when treated collaboratively by oncology and dermatology teams.

This review describes how cutaneous toxicity from kinase inhibitors, immune checkpoint inhibitors, and chemotherapeutics could potentially serve as a biomarker for anticancer treatment efficacy, but highlights the need for more extensive research to confirm this association.

This review discusses micro-segmental hair analysis for forensic toxicology, emphasizing its potential to provide detailed drug distribution profiles and its application in investigations, while noting the method's limitations and future perspectives.

Excessive selenium in supplements can cause hair loss and nail issues.

This review summarizes existing studies on toxic agents that can cause alopecia, with thallium and colchicine having the most established links, while others like botulinum toxin A need further investigation.

This review summarizes common skin-related side effects of BRAF inhibitors and immunotherapy in advanced melanoma treatment, reporting no new clinical findings, and emphasizes consensus management to improve patient outcomes.

In this pilot study, botulinum toxin was found to be a safe and effective treatment for androgenetic alopecia in most participants, though larger studies are needed to confirm these findings.

This study found that finasteride was associated with more reproductive adverse effects, including sexual dysfunction in men and fetal harm in women, compared to minoxidil in reported alopecia cases.

This review discusses the dermatological applications of botulinum toxin, including off-label uses for various skin conditions, and calls for a better understanding of underlying muscular anatomy for effective clinical practice.

This study found that Teucrium polium L. subsp. geyrii Maire extract demonstrated a large safety margin in acute and subacute toxicity tests on mice and significantly enhanced wound healing in rats, especially with callus extract, by improving cell proliferation and wound contraction.

This article reviews the cutaneous reactions and characteristic skin changes associated with chemotherapy, radiation therapy, and new targeted cancer treatments, reporting no new clinical results.

This article explores potential mechanisms of acneiform skin eruptions linked to EGFR inhibition in cancer patients, focusing on EGFR's role in controlling IL-1-dependent inflammation at hair follicles, but reports no clinical results.

In this study on rats, botulinum toxin–A injection was reported to reduce contraction in wounds and skin grafts, with changes in inflammation and collagen arrangement also observed.

This study found that high doses of ethyl acetate extract from Tridax procumbens can have specific toxic effects in rats, including organ damage and significant changes in some serum biochemical parameters.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

In this study of patients with androgenetic alopecia, botulinum toxin type A was found to significantly increase hair counts and improve hair density and coverage, with enhanced results observed when combined with oral finasteride, revealing a safe and effective treatment approach without adverse effects.
