MOERIE Ultimate Hair Growth Serum is a caffeine-boosted scalp serum blending niacinamide, biotin, fulvic acid, and amino acids in a lightweight formula targeting hair thinning and loss. Applied daily via pipette directly to cleansed scalp, it promises to stimulate growth at the root and improve circulation.
Hero actives: Caffeine (blood flow), niacinamide (B3—scalp health), biotin (B7), fulvic acid, plant extracts, amino acids.
Benefit: Scalp circulation, root stimulation, and the appearance of thicker, faster-growing hair. Growth claims lean anecdotal; the formula is solid but unproven in clinical trials.
Scent & feel: Lightweight serum (not oily); applies clean. 92% natural, 100% vegan, PETA-certified cruelty-free.
For whom: All hair types, especially those with thinning or slow growth. Fine-haired users report minimal greasiness. Curly and coily hair routines appreciate the scalp-focused approach.
Honest caveat: Regrowth serums thrive on anecdote and expectation; MOERIE's active blend is legitimate, but clinical hair-density data is absent. Community feedback is favorable but not overwhelmingly effusive. Dropper occasionally leaks per a minority of reviews.
