Hair after 40

Perimenopause Hit at 47. My Thick Ponytail Became a Rat Tail. At 50, Here's How I Finally Wore My Hair Down Again (It's NOT HRT, and I Didn't Need Minoxidil)

Her ponytail under a tennis cap, before and months after

Last Saturday I sat right under the chandelier at my 50th birthday dinner with my hair down on my shoulders... And when my sister showed me the picture she took, I cried in front of the whole table.

It Started With a Little More in the Drain

A year ago I wouldn't have sat under that chandelier.

A year ago my ponytail had got so thin I was scared I was going to go bald.

It started at 47, in peri. Nothing big at first. A little more hair in my brush. A little more in the drain.

It didn't stay that way.

Within a year my hair was falling out in clumps, and I would cry washing it because of the amount every time. It felt like I had lost about 40 to 50% of my hair.

My hair tie went around 3 times, and I was forever putting what I had left in a clip. Under the bathroom light I could see my scalp through my part.

Then it was everywhere. On my pillow. On my sweater. After I dried it in the morning, the sink looked like someone got a haircut.

I stopped wearing it down. I checked the lighting before I sat down anywhere. Some days I didn't want to leave the house.

One day in the break room, a male coworker asked me if I was sick. I said no. Then I realized he meant my hair.

I went to the bathroom, and the woman in the mirror didn't look like me.

So I took my hair to my doctor in a bag. My blood work came back fine. He smiled and said it'll pass.

I know hair isn't everything. But I was headed down the wig road.

Then my hairdresser told me what no doctor had.

I Tried Everything. Before I Tell You What Worked, Here's What Didn't

I'd done it all. Biotin, collagen, rosemary oil, the shampoos, the conditioners. Nothing seemed to be slowing it.

The rosemary oil, every night, until a friend asked about the smell. There was a week where I thought my brush looked better. Enough to tease me.

The shampoos and the foams. I once spent half an hour in the pharmacy aisle reading labels and walked out feeling lost.

Then the last thing on the table. Minoxidil, every day, for the rest of my life. And if I ever stopped, the hair it grew could fall out again.

For the rest of my life. Read that again.

Nobody had ever looked at my scalp. They checked my blood, said normal, and sent me home. Insurance doesn't cover most women's issues anyway. The system wasn't built to fix this. It was built to say it'll pass.

That was 2 weeks before I found out why none of it ever stood a chance.

What My Hairdresser Told Me With the Dryer Off

Her own mirror photo in the salon chair, her hairdresser behind her with the dryer lowered

I got my hair cut, and I was telling my hairdresser about my hair coming out. She's been in menopause for 5 years herself.

She turned off the dryer, lowered her voice and asked, "Can I tell you what your doctor probably won't?"

She told me not to accept yep, your numbers are normal. "That's just a doctor's way of saying your body stopped producing estrogen. But estrogen was never the whole story."

Then she put it like this. Think of a camel's back. For years before menopause, stress hormones had been holding my hair in its resting phase. DHT had been shrinking each hair a little finer. My scalp had been wearing down. Then estrogen drops, and that's the last straw. That's when the thinning shows.

"Your hair isn't dead," she said. "It's resting. And nobody's been treating the other 3."

Then she went down my list. Biotin only helps if you're low in it. The oils I'd been rubbing in just sat on my scalp. The shampoos were down the drain in a minute. Minoxidil works on blood flow, 1 of the 4. HRT can help with a lot, she said, but on its own it's the hormone part only.

And most of what I'd bought had its growth ingredients at a trace. Just enough to print the name on the label.

It was my hormones and my scalp, not me. I was definitely panicking before that.

I went home that night and looked it all up. I had to see it for myself.

She Was Right. Then She Showed Me What to Use

Her hand holding the KYIR Fuller bottle at the salon station

A dermatology journal published a review this year that looked at 13 studies of estrogen therapy and hair in menopause. Estrogen didn't consistently help hair grow back.¹

Harvard researchers found the stress hormone keeps the follicle's stem cells resting, through the part under the follicle that tells them when to grow. It was in mice, but it was the first time anyone had explained the resting part to me.²

And a review of women's hair after menopause explained how falling estrogen tips the balance toward DHT, which shrinks the follicle.³

So the real question was how you answer all 4 at once.

That's what the bottle she'd pulled off her shelf was for. She told me to read the ingredients.

It was KYIR. They call it the Follicle Synergy System, 5 parts in 1 step:

"Biotin alone doesn't do it. Rosemary oil alone doesn't do it," she said. "All 4 have to be answered at once, at a dose that's really there."

She told me to try it before I thought about anything for life. A few drops on my scalp once a day, like in the studies. The women she knew who used it morning and night tended to see it sooner. About 30 seconds. No prescription.

I was a little skeptical at first. But for the first time, someone had explained the why. So I tried it.

What Changed, Week by Week

I'd already spent a fortune on things that did nothing. What was one more bottle?

Day 1. It wasn't sticky, and it dried pretty quick. My roots had some lift for the first time in months. That was all, and I didn't expect more.

Week 3. Less in my brush after washing. Not gone. But less.

Week 6. I noticed a difference in my shedding. It reduced back to normal shedding in the shower. No more big clumps. And little hairs were starting to pop up at my widening part.

Month 3. My thin areas were filling in with new hair, and I had volume again. Even my hairdresser noticed a difference.

Month 6. My sister noticed it first. She asked how my hair got thicker.

Month 11. My hair tie goes around twice again. I wash my hair without counting what's in the drain. I wear it down. And the woman in the bathroom mirror looks like me.

My hairdresser said the best line, though. "You came in here ready for a wig. Look at you now."

It's slow going, but progress is progress. Nobody has told me it'll pass since. It didn't pass. It got better.

I'm Not the Only One

A wall of 5 star KYIR reviews from customers

Before I told anyone about it, I read KYIR's reviews to see if it was just me. These are the ones that answered what I would have asked.

Kelly Glor: “Ladies getting older is not fun. Hair just doesn't give us the life it did in our youth. GLP-1 and hormonal changes left my hair breaking and falling out. This bad boy is helping bring my hair back to life!!!”

Mel-Marin: “I have definitely seen growth on the sides of my hair in the last 4 weeks and less shedding. I use it morning an night. I only wash my hair 1-2 times per week, and this doesn't make my hair feel dirty or greasy.”

Jamie Harlan: “I noticed my part was looking wider and I could see more of my scalp. I used 1 bottle and could tell a difference after 1.”

Japonesa Read: “I bought this for my mom, who is nearing her mid 70s and the new hair growth I’ve seen on her head is astonishing. She is so happy and has started to gain her confidence again.”

Sara Robinson: “I've only been using it for 30 days, so I will continue to update as the months go by. I just purchase 3 more bottles because I do think it is helping me keep the hair I have left.”

You Might Be Wondering

If this works, why didn't my doctor tell me?

Most doctors get a few minutes and a blood test, and when the numbers come back normal, that's where it stops. Mine wasn't a bad doctor. Hair just isn't what anyone checks, and insurance doesn't cover most women's issues anyway.

Isn't it just a fancy rosemary oil?

Rosemary oil works on the surface of the scalp. This has both growth ingredients at 3%, the dose the studies used, printed on the bottle, plus the DHT part and the stress part. 4 things in 1 step. Nothing I'd tried did more than 1.

I'm on HRT. Can I still use it?

It's a scalp treatment, not a hormone, so it doesn't change your hormones. Women use it alongside other routines. If you're on a prescription, ask whoever prescribed it what fits you.

How long until I know?

Less in the drain can come within weeks. Baby hairs after about a month. Results you can see by month 3. The guarantee is 90 days because that's how long a real test takes.

What if it doesn't work for me?

I used mine every day for 3 months before I was sure. If you use it as directed for 90 days, take a photo at the start of each month and don't see a difference, KYIR refunds you. Return shipping isn't covered.

Why This Worked When Everything Else Didn't

The crown on day 1 and day 90

Everything I'd bought did 1 thing. Biotin fed my hair. Rosemary oil sat on my scalp. Minoxidil was blood flow. HRT was hormones. Each one left the rest running.

When the stress part is eased, when DHT is held back, and when the follicle gets both growth signals at the dose the studies used, it can come out of rest. That's all it is. It isn't magic.

And on the 5 bottles, it came to less than $2 a day.

Here's What I'd Tell You If You Were My Sister

KYIR bottles on the filling line

Use it every day. Once a day is what the studies used. Morning and night if you can, because people who do tend to see it sooner.

Give it time. Less in the drain can come within weeks. Baby hairs after about a month. Results you can see by month 3. A full ponytail takes 9 to 12 months, depending on where you start.

So don't buy 1 bottle and judge it at week 3. That's the mistake I almost made.

Now here's the hard part

It has sold out 5 times. It's made in small batches with plant-derived preservatives, because high doses of several growth ingredients are hard to keep stable. It took them 30+ versions to get it right.

What it's worth

Think about what's already in your cabinet. Mine was full of half-used bottles. Then add the appointments where someone said it'll pass.

5 bottles is 150 days. KYIR lists them at $370. On their intro offer they're $259, 30% off, with the Scalp Tool and the GENTLER Towel free. That's $1.73 a day.

I'm not telling you that for the money. I'm telling you because I'd want my sister to start with enough to get to month 5. And if your mom or your sister is where I was, that's the one to share.

Use it as directed for 90 days and take a photo at the start of each month. If you don't see less shedding, more volume and new growth, send the photos and get a full refund. Return shipping isn't covered.

You're at a Crossroads

Her birthday dinner under the chandelier, her hair down on her shoulders

I used mine every day for 3 months before I was sure. You get 90 days. If it does nothing for you, you send the photos and get your money back. The only way to lose is to keep doing what you're doing now.

Path 1: nothing changes. The clumps in the drain. The clip. The hair tie on its 3rd loop. Checking the lighting before you sit down. Another appointment where someone smiles and says it'll pass. And the stress, the DHT and the wear keep piling on, with estrogen as the last straw.

Path 2: you start tonight. In a few weeks, less in the drain. Around month 1, baby hairs at your part. By month 3, the volume your hairdresser notices. And one morning, a hair tie that goes around twice again.

Nothing changes if nothing changes.

Jen

P.S. People ask me if it lasts. I'm 11 months in and I still put it on every morning, like brushing my teeth.

P.P.S. Last week I wore my hair down to dinner and didn't check the lighting once. If yours is still in a clip, it was never you. It was the last straw nobody told you about, and 3 others nobody treated.

Comments

Sara: How long do I have to use this and if I stop, will the hair that grew up to tha point fall out?

Jen (reply): I'm 11 months in and still use it every morning. Nobody can promise it's permanent and I wouldn't trust anyone who did. Mine is just part of getting ready now.

Diogo: I tried them all! This worked 2 months in and its working! I love that its no greasy! Try this!

Michelle: Does it make your hair nasty and sticky like so many scalp products?

Jen (reply): Not at all. With thin hair I was worried about that too. It isn't sticky, and I use it on wet or dry hair.

Karen: Mine working. My hairdresser is blown away

Lori: How long does it take to work? I'm on week 3 so maybe too soon to see any changes? ❤️

Jen (reply): Week 3 was too soon for me too. The drain changed first, around week 6. The baby hairs came after that.

Denise: $74 for 1 bottle but if it works, that's not a bad price. Got the 5 so I'd actually stick with it.

Tracy: Sending this to my sister. She's been crying over her ponytail since the summer.
