The 2010 Co-Creations relaunch brings collaborations with recognized international experts in trichology and hairstyling. Yuko Yamashita is a Japanese expert in permanent thermal straightening (Japanese Hair Straightening), a technique that modifies the structure of curly hair, making it permanently smooth through chemical treatments and controlled heat. Dr. Francesca Fusco is an American dermatologist specializing in trichology who studies scalp health and conditions such as alopecia, seborrheic dermatitis, and hair loss. These collaborations give scientific and professional credibility to the brand by communicating that formulas are developed with input from specialists instead of simple anonymous laboratory chemists, a strategy that responds to increasingly informed consumers who verify expertise behind beauty products.
