Tatiana Irizar Caffeine Hair Growth Serum 1oz

Tatiana Irizar Caffeine Hair Growth Serum is a peptide and botanical serum targeting scalp health and the appearance of fuller hair. The formula combines caffeine, rosemary, amla, biotin, nettle, and panthenol — evidence-backed actives for circulation and follicle support. Applied daily via dropper to the scalp (1–1.5 ml), it aims to deliver visible density improvements within 90 days. Non-greasy, fresh herbal scent, paraben- and sulfate-free, vegan and cruelty-free. Made in the USA and IBA-certified. Growth claims are largely anecdotal (90-day promise supported by user feedback rather than clinical data). Best suited for those seeking a lightweight, botanical serum without heavy oils; less ideal for those wanting a traditional scalp oil. Cost-per-oz is mid-to-premium (~$44/oz), and dropper control is reliable but applicator durability reports vary.
