While the couture outfit made an impact, it was Aishwarya's dramatic hair transformation that quickly caught attention. The actor debuted fiery red tresses for her Paris appearance, styling them in soft waves with a side parting.
Her beauty look stayed equally striking, with winged eyeliner, feathered brows, rouged cheeks, subtle contouring and a statement red lip.
Aishwarya was among a star-studded line-up at the L'Oreal Paris event. She shared the runway with names including Viola Davis, Kendall Jenner, Cara Delevingne, Jane Fonda, Eva Longoria, Andie MacDowell, Simone Ashley and Marie Bochet.
