Hair care has withstood the test of COVID-19—and this month's C&T highlights this category from root to tip. First, it presents a "Scalp Biology 101" feature, and proposes an approach to selective scalp cleansing. Also highlighted is a technology to protect and restore hair's condition, sensorially. It then delves into formulating sustainable hair conditioners and preserving textured hair care. Finally, it explores a natural solubilizer and preservative booster for clear systems. We hope this issue stands steady to support your hair care development efforts.
