From the founder

At 49, I started losing density at the temples.

I'm a board-certified OBGYN. I've spent 18 years in private practice in Connecticut, mostly with women between 40 and 65. My patients had been telling me the same story for years: HRT fixed almost everything except the hair. I gave them the same answer most physicians give — there's nothing topical worth recommending that won't interfere with your other meds. Then it happened to me.

I went looking. Nothing in the topical category was built for the menopause scalp shift. Nothing addressed the inflammation, the microcirculation drop, and the relative androgenic shift at the follicle without entering the hormonal pathway.

So I commissioned the formulation. Two years of work with a cosmetic chemist with 14 years of scalp experience and a peer-reviewed dermatology consultant. Four ingredients with published research behind each. No iodine. No kelp. No saw palmetto. Designed to layer with HRT and topical minoxidil, not replace either.

I use it myself. So does my mother. So do thirty of my patients.

PERIDAE is what I wish I'd had at 49.

My part-line is finally closing back up at 54

"I'd been on HRT for two years and the hot flashes stopped but the hair never came back. By week 8 my shower drain was different. By month 4 my part is closing. I'm still on my HRT. PERIDAE is the layer I didn't know I was missing."

Non-greasy. Doesn't fight my Rogaine.

"I tried Women's Rogaine four months and quit because of the dryness. PERIDAE is the first thing my scalp didn't reject. Month 4 my ponytail is thicker than when I started. I no longer use minoxidil. I just use PERIDAE."

No iodine. No kelp. Compatible with my thyroid meds.

"Quit Nutrafol after 6 months because of the iodine concern with my thyroid panels. PERIDAE explicitly publishes no iodine, no kelp, no saw palmetto. After 90 days noticeably less hair in the drain. Wish I had switched sooner."

For Women 45+

Your menopausal scalp is going through a shift no one told you about.

Cross-section illustration of a hair follicle in two states — healthy vs. shrunken in menopause

After 45, key hormones decline. The scalp environment shifts. Follicles shrink. Shedding outpaces regrowth. By the time you see scalp in a selfie, it has been happening for months.

A woman on r/Perimenopause described what her dermatologist told her: "It's androgenic. The decline in progesterone and estrogen is making DHT more dominant and shrinking the hair follicles." This is the menopause scalp shift. It is not stress, not styling, not your shampoo. Even when HRT, thyroid panels, and ferritin are in range, the topical scalp shift can persist independently. PERIDAE is built for it.

The Solution

PERIDAE supports the menopause scalp shift.

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.

  • 38 researched ingredients, full INCI list on page
  • Topical only. Does not enter the hormonal pathway.
  • No iodine. No kelp. No saw palmetto. Won't interfere with thyroid meds or panels.
  • Compatible with HRT and topical minoxidil

Five women. Five photos. The same 120-day money-back.

HRT did everything for me except my hair. Two years in and the part just kept getting wider. I added PERIDAE without changing anything else. By week 8 the brush was less full. By month 4 the part is closing back up.

Rogaine dried my scalp until it itched, so I quit. PERIDAE absorbs and disappears. By month 4 my ponytail felt thicker than it had since I was 45, and I haven't touched the foam since.

I'd already done the six-month wait on supplements and got nothing. With PERIDAE the first thing I noticed wasn't length. It was less hair in the drain by week 8, and less scalp in my selfies by month 4.

8 years past menopause. HRT helped my joints but my hair never came back. By week 10 the shower-drain count was visibly down. By month 4 my part is closing. I'm not on minoxidil and don't want to be — this fits.

Still cycling. OBGYN said wait on HRT. Started PERIDAE because the elastic wraps three times now where it used to wrap two. By week 8 less hair in the brush. Month 4 the part is closing back up — first thing I have tried that I can actually see working.

The Routine

30 seconds. Once a day. That is the entire routine.

PERIDAE is a leave-in scalp serum. No rinse. Use it morning or evening.

  1. Part your hair where the scalp is most visible — center, side, crown, or temples. Hand holding the PERIDAE dropper
  2. Apply 5 to 7 drops along the part-line. Aim for the scalp, not the hair. The dropper is calibrated. One squeeze is roughly one milliliter. Dropper placed at the part of the hair
  3. Massage 30 seconds. Leave in. No rinse. Fingertips massaging serum into scalp
Pairs with your existing routine. If you use topical minoxidil, apply PERIDAE first and let it dry 5 minutes before applying minoxidil. Either order works in practice — apply at opposite times of day if your routine allows.

Will PERIDAE interfere with my HRT?
PERIDAE is a topical scalp serum, formulated with input from menopause medicine specialists. It does not enter the hormonal pathway. The INCI list is fully visible on this page and contains no hormonal-active botanicals. Designed to layer with HRT, not replace it.

Is PERIDAE compatible with topical minoxidil?
If you use topical minoxidil, apply PERIDAE first and let it dry 5 minutes before applying minoxidil. Either order works in practice — apply at opposite times of day if your routine allows.
How long until I see results?
Honest 4-phase ladder. Weeks 1-4: scalp feels different, baby hairs noticeable in the part-line. Weeks 5-12: less shedding visible in the brush and the shower. Months 4-6: density and scalp visibility improve. The 120-day money-back guarantee covers the test window.
Will PERIDAE dry out my scalp the way Rogaine did?
No. PERIDAE is water-based and fast-absorbing. It does not contain alcohol denat as a primary solvent. The pH is balanced for scalp health.

No. PERIDAE contains no iodine, no kelp, and no saw palmetto. Will not interfere with thyroid medication or thyroid panels.

Is PERIDAE only for women on HRT?
No. PERIDAE is made for any woman 45 to 60 in peri or menopause noticing visible hair changes. Whether you are on HRT, on topical minoxidil, on both, or on neither, PERIDAE was formulated to layer into the routine you already have.
I'm not on HRT (or I'm 60+ post-menopause / pre-HRT considering / can't take HRT for medical reasons). Is PERIDAE for me?
Yes. PERIDAE works whether you are on HRT, on minoxidil, on supplements, on neither, or coming off any of them. The mechanism is topical scalp-only — it does not replace, contradict, or require any other product. Women in their late 40s through their 60s use PERIDAE across the full spectrum of medical situations, including women whose HRT is medically off the table and women years past menopause whose hair never came back.

Add the 30-second scalp step women 45-60 are talking about.
