Palmer's Cocoa Butter & Biotin Length Retention Scalp Oil (2 × 5.1 oz)

Palmer's Cocoa Butter & Biotin Length Retention Hair and Scalp Oil is a dual-action formula combining cocoa butter and biotin to hydrate the scalp and support hair strength and length retention. Applied via dropper to the scalp and throughout the hair, this oil targets dryness and breakage with a rich, nourishing blend. The product has earned solid consumer trust within the drugstore-luxury category, with mostly positive feedback on scalp hydration and hair softness. Growth claims remain largely anecdotal rather than clinically proven, though users consistently report improved hair manageability and reduced split ends. Best suited for dry to normal scalp types and textured hair, though some fine-haired users note a heavier feel. Cocoa butter and biotin are well-regarded botanicals with reasonable evidence for scalp and keratin support, though the blend is primarily a sealing and conditioning oil rather than a circulation-stimulating treatment. Pack of 2 (5.1 fl oz each) offers strong value per ounce at drugstore pricing.
