A topical scalp serum that works alongside the routine you already have, without entering the hormonal pathway.
What you'll see: less shedding in the shower between weeks 5 and 12, and a less visible scalp by month 4. PERIDAE works on the menopause scalp shift so the wider part gradually closes back up. Formulated with input from our Menopause Medical Advisory Board (Dr. Karen Whitfield, Dr. Joanna Kessler, Dr. Linda Reyes). Three actions on the scalp, all topical, all daily.
One. Inflammation reduction at the root using rosemary acid[1] and peptides[2].
Two. Circulation support at the scalp using topical caffeine[3] and peppermint[4].
Three. Nutrient delivery to the scalp using biotin and plant extracts: red clover[5], mung bean, stinging nettle[6], and bhringraj[7].
Each active is grounded in published topical-scalp research. Rosemary topical was studied head-to-head against minoxidil 2% in a 6-month randomized trial[1]. Caffeine topical's stimulation of human follicle elongation was documented in two independent ex-vivo trials[3]. Full per-ingredient references appear at the bottom of this page.
PERIDAE is topical only. It does not enter the hormonal pathway. PERIDAE is designed to layer with HRT and topical minoxidil — not to replace either. The full INCI list is on this page. No iodine. No kelp. No saw palmetto. Will not interfere with thyroid medication or thyroid panels. Topical scalp application of the listed plant extracts (red clover, mung bean, stinging nettle, bhringraj) has no measurable systemic estrogenic activity at the concentrations used.
