January 1943 in “Endocrinology” In this study, adrenalectomy in rats on a diet lacking certain vitamin B components reversed fur graying and enhanced hair growth.
This study reports the development of a natural hair-coloring system using size-controlled ink particles from cuttlefish ink combined with chitosan, achieving darker and more uniform black coloration on hair than existing plant-based natural colorants, without the need for metallic mordants.
