While we love a natural air-dried look for summer, there’s something about polished, glossy hair that screams winter fierceness. That’s why shoppers are raving about L’Oreal Paris Bond Repair Oil-In-Serum, a revitalizing hair oil delivering “stronger, sleeker hair;” and it’s the serum Jane Fonda wore in her hair during the 2025 SAG Awards. She had her hair done by Jonathan Hanousek for L’Oréal Paris, and this serum is the one that gave her those glamorous waves.
This $13 bond repair serum is infused with science-backed citric acid, the serum works overtime to repair brittle hair bonds. According to one shopper, the serum “revitalizes dry hair,” making it “silky and soft.” That user also noted the bonus of a “pleasant scent” with flirty hints of mandarin, rose, and amber — meaning your hair smells as good as it looks.
