Jennifer Lawrence is officially in the beauty business. The Oscar-winning actress is launching mes°, a “biodesigned haircare” line built with Boston biotechnology company Arcaea, with products set to go on sale October 27, 2026.

Lawrence revealed the venture on October 16 with an Instagram carousel touring the hairstyles of her film career — from The Hunger Games to Silver Linings Playbook to Mother! — pointing followers to the brand’s site, which invites visitors to sign up ahead of launch day. The move is a notable one for an actress who has famously kept commercial deals at arm’s length; it is also well timed, arriving just weeks after she joined Instagram in September and quickly built an audience of millions — a launch channel most beauty startups can only dream of.

True to the tease, the brand is holding its cards close: formulations, product lineup, prices and retail partners have not yet been disclosed, with details expected at launch. What is confirmed is the concept — haircare designed with biotechnology through Arcaea, a company that develops beauty ingredients through biology rather than traditional chemistry.

mes° joins a crowded field of celebrity-founded beauty brands, but Lawrence’s approach — quiet buildup, a biotech partner, and a hard launch date — makes it one of the more intriguing business moves of the season. All eyes now turn to October 27.
