1. Your hair isn’t falling out. Your follicles are shrinking.

Your part looks wider. Your ponytail feels thinner. So you assume you are shedding more.

Usually you are not. You still have the same number of follicles. Each one is just making a finer hair than it used to.

Estrogen is what keeps a follicle growing. When estrogen drops, the growing phase gets shorter, so each hair has less time before it rests and falls out. The next cycle, that follicle makes something finer. Then finer again. Eventually it stops surfacing at all.

That is why this creeps up on you instead of happening overnight.

About half of women notice visible thinning during this stretch of life. Your hair is going through perimenopause right alongside you.

2. Estrogen was doing three things for your hair

It kept follicles in their growing phase. It kept the collagen layer of your scalp thick, which is the actual home your follicle sits in. And it blocked DHT, the male hormone that shrinks follicles.

When estrogen drops, all three protections collapse at once. Follicles grow for less time. The home shrinks. DHT gets to work. That is why hair gets finer and sheds faster in the same season.

Your follicles read estrogen through receptors called ER-beta. Those receptors are still there. The signal is what went missing.

3. Serums, shampoos and biotin all work on the wrong layer

Thickening shampoo coats the hair you already grew. Biotin helps if you are deficient in it, and most women are not. Scalp serums have to be applied every single day, forever, or you go back to where you started. Who has time for that.

Neither one reaches the follicle. The follicle is where this is happening.

That is why the usual advice buys you a few good hair days, and then you are back where you started.

4. Red clover works on the same receptors estrogen did

Peri/Menopause Essentials is built on red clover isoflavones. They act on the ER-beta receptors your follicles are waiting on. Bergamot and olive polyphenols cover the metabolic side of the transition. Two of the three have EU-approved health claims.

Two capsules every morning. It works on the follicle, not the strand.

Hair grows in cycles, so give it a season, not a week. Results vary.

5. 93% reported an improvement in hair quality

In an independent 3-month study, 93% of women reported their hair quality improved.* 93% reported less brain fog. 90% reported fewer hot flashes. Same hormone shift underneath all three.

*Self-reported by 42 women ages 40-57 over 3 months on the Menopause Rating Scale. Independent open-label study, NCT05617287. Two of three compounds carry EU-approved health claims. Results vary.

Take it and see! It’s amazing!

“I have been taking this for a month. I love it. Within 2 weeks I felt a change in my libido. Within 3 weeks I noticed more shine in my hair. My mood has been more stable and I have not experienced a single hot flash… I lost weight… but I have been working out a bit more during the month. But that could be due to my better mood! Awesome product.”

Women on what changed after three months

★★★★★

Hot flashes be gone!

“Honestly, I don’t think I can do without it. I used it for 3 months with great results, went off of it with regrets and decided to get back on it for immediate relief. I don’t know how or why it works, but it sure does for me.”

Definitely recommend

“I started taking the peri/menopause pills over 6 months ago. I absolutely love them. About three weeks after starting them, my night sweats were gone and I haven’t had any since. My sleep also improved drastically. I’m sleeping through the night now. I would have hot flashes the week before my period and now those are much better as well. They definitely have made me feel so much better.”
