Acidic Grow Full System
Redken (L'Oréal) · For GLP-1 shedding · shampoo $34, bundle ~$130
Redken's Acidic Grow Full is one of the first lines to explicitly consumer-test on GLP-1 users, with 91% reporting fuller-feeling hair. Credit the honesty: the brand itself says it does not make new hair, so this is a cosmetic volume and appearance boost while you wait out the shed. Individual reviews are still limited.
Who it is for

Who it is not for
