Abstract


Chemotherapy-induced alopecia (CIA) causes significant psychological distress, prompting the need for effective prophylactic or therapeutic interventions. Phenobarbital, a potential agent for re-purposing towards CIA prophylaxis and/or treatment, activates ABC receptors to expel chemotherapeutic agents from hair follicles. Squarticles, nanostructured lipid carriers enriched with squalene, are emerging nanocarriers that selectively target hair follicles via interaction with physiological sebum.
