Jennifer Lawrence used a Friday Instagram carousel of her own film hairstyles to tease Mes°, a hair care brand she biodesigned with Arcaea, the biotech company that closed a $78 million Series A round.

What did Lawrence post?

Lawrence, whose credits include The Hunger Games, Mother! and Silver Linings Playbook, shared the post on Friday. The carousel ranged from sleek updos to blond bangs to red hair to "super messy" looks. A link to Mes° appeared under her Instagram handle, which carries no bio text. Lawrence joined the platform in September with a video joking: "So yeah, I'm giving it a shot and if anyone says anything negative I'll quit immediately."

What does the Mes° landing page show?

The link resolves to a single page stating the brand was "biodesigned by Lawrence and Arcaea." A tagline reads "a new perspective on beauty." The page lists the date Oct. 27 and a sign-up line that asks visitors to "get curious." No product formulas, SKUs, price points, hero ingredients or retail partners appear. The brand has issued no press release and no comment beyond the page copy.

Who is the biotech partner?

Arcaea, founded by MIT graduate Jasmina Aganovic, describes itself as a biology-driven beauty company. The firm raised $78 million in Series A funding from a roster that includes Chanel, Givaudan and Olaplex. That investor lineup ties a heritage fragrance house, a Swiss flavors and fragrances supplier and a publicly traded bond-repair brand into one biotech bet.

Where does Mes° fit in the celebrity beauty field?

Lawrence joins a celebrity founder cohort that already numbers at least five in hair and skin:

• Blake Lively
• Beyoncé Knowles-Carter
• Lady Gaga
• Hailey Bieber
• Selena Gomez

Mes° lands in a category where Olaplex — one of Arcaea's own Series A investors — has set the clinical-language benchmark for bond repair. A Lawrence-attached label will be measured against that standard and against the founder-led lines from Lively, Bieber and Gomez that already compete in the prestige hair space.

What does the funding mean for a Lawrence launch?

The $78 million Series A gives Arcaea — and by extension Mes° — a financial base that exceeds the typical celebrity brand launch. Chanel and Givaudan bring fragrance-house expertise; Olaplex brings direct category overlap. Aganovic's MIT training and Arcaea's biology-driven positioning give the Mes° pitch a technical angle that the celebrity-led lines from Lively, Bieber and Gomez have not foregrounded.

What happens next?

The Oct. 27 date on the Mes° landing page points to an announcement or product reveal inside three weeks of Lawrence's Instagram post. Mes° has not disclosed its distribution channel, product count or price architecture. The next update will arrive either on the page itself, through Arcaea's investor base, or via Lawrence's Instagram account — and whether Mes° ships with the technical credentials its backers imply or rests on Lawrence's name alone will determine whether the Oct. 27 reveal lands as a category entry or a one-cycle press release.
