The 4-step DHT defense made for women whose hormones turned on their hair.

— 01 · The Problem

You did everything "right." Your hair thinned anyway.

Maybe it started a few months after you came off birth control. Maybe you've carried PCOS your whole adult life. Either way, you know the signs: a part that keeps getting wider. A ponytail that wraps one extra time. A drain that makes your stomach drop every single morning.

You've tried the biotin. The gummies. The spearmint tea, the expensive shampoo, maybe even the spiro your doctor finally agreed to. Some of it helped a little. None of it fixed it.

Here's what no one connected for you: the pill was suppressing your androgens. PCOS raises them. Both roads end in the same place — a hormone called DHT reaching your scalp and choking the follicle until the hair grows back finer, then wispier, then not at all.

That's why nothing you tried worked. You were feeding a strand that was never starving. It was being strangled.

And every product on the shelf was built to feed hair. Not one was built to fight the hormone doing the damage.

— 02 · Lead Scientist

"No one was treating hormonal hair loss where it actually happens — at the scalp."

We built rebloom because the entire category was aimed at the wrong place. Oral saw palmetto has to survive your gut, your liver, and your bloodstream before a fraction of it ever reaches a follicle. We asked a simpler question: what if you put the DHT fighters directly on the skin where DHT is made?

The 4R Method came out of that question. Not one ingredient blocking one enzyme, but four steps rebuilding the scalp DHT scorched.

— 03 · The Science

They block DHT once. We block it, calm it, feed it, and wake it back up.

DHT binds to the follicle and miniaturizes it. When your androgens were low, or the pill was masking them, that damage stayed quiet. Now the shield is gone and DHT is getting through.

But blocking DHT is only step one. By the time you notice thinning, the hormone has already inflamed the scalp, strangled its circulation, and put the follicle to sleep. Block DHT alone and you stop the bleeding, but the ground it burned is still dead. That is why single-ingredient products plateau.

R1 · Reduce

Cut the DHT at the source

Saw palmetto, applied where DHT forms, slows the enzyme that converts testosterone into DHT.

R2 · Relieve

Put out the fire

Baikal skullcap and rosemary calm the low-grade inflammation DHT leaves behind on the scalp.

R3 · Restore

Re-water the soil

Arginine reopens the microcirculation DHT strangled, so oxygen and nutrients reach the root again.

R4 · Regrow

Wake the follicle

Five signal peptides tell the dormant follicle it's safe to grow now that the poison is cut and the fire is out.

The others give you a lock on the door. We rebuild the whole house behind it.
— 04 · The Timeline

What happens once you finally treat the root.

Your follicle runs on a 90-day cycle, so real change takes real time. This is the timeline most women report.

01
Week 2

Shedding slows

Less hair in the shower and the brush. The scalp feels calmer, less itchy, less reactive.

02
Month 1

The damage stops

DHT stops choking the follicles you still have. What's on your head stays on your head.

03
Month 3

Baby hairs return

New growth along the hairline and part. Dormant follicles start switching back on.

04
Month 6+

Visible density

A fuller part, a thicker ponytail, and a mirror that finally starts agreeing with you.

— 05 · Why rebloom

Built around the layer every capsule misses.

Most "hair vitamins" feed the hair. They never touch the hormone driving the loss, and even the ones that try send it the long way around, through your whole body. rebloom works on the scalp, at clinical intent, once a night.

On the scalp, not through your gut

Saw palmetto applied where DHT is made, not swallowed and diluted before it arrives.

Four steps, not one

Reduce, relieve, restore, regrow. The others stop after the first.

No hormones, no dependency

Nothing synthetic. Stop whenever you want without losing your progress.

Made for hormonal hair

Formulated for PCOS and post-pill thinning, not repackaged men's prostate pills.

— 06 · The Ingredients

The right actives. Where they can actually reach.

Having the right name on the label isn't the same as putting it where the damage happens.

Reduce · at the source

Saw Palmetto

Slows the enzyme that turns testosterone into DHT, applied directly to the scalp instead of routed through digestion.

Relieve · the inflammation

Baikal Skullcap & Rosemary

Antioxidant botanicals that calm the perifollicular inflammation DHT leaves behind.

Restore · the circulation

Arginine

A nitric-oxide precursor that reopens the microcirculation feeding the root.

Regrow · the signal

5 Signal Peptides

sh-Polypeptide-1, 9, 11 and sh-Oligopeptide-2, 10 — the messengers that tell a dormant follicle to grow again.

"I've watched patients get results in the same range as topical minoxidil, without the shedding rebound or the facial-hair side effects that terrify this group."

— Dr. Lena Okafor, board-certified dermatologist

Questions women like you ask

I have PCOS and I'm already on spiro/metformin. Does this fit? +

Yes. rebloom is the topical scalp layer, made to sit alongside whatever your doctor has you on. It doesn't touch your hormones or your metabolism — it works on the scalp, where your prescriptions can't reach.

My shedding started after I came off the pill. Is it too late? +

Post-pill androgen rebound is exactly the window this was built for. Follicles don't die easily, they shrink. The earlier you start once the shedding begins, the more you protect.

My labs came back "normal." Doesn't that mean it's not hormonal? +

Standard panels miss a lot, and "normal range" isn't the same as optimal. If your part is widening, your scalp is telling you something your bloodwork glossed over.

Will it make me grow facial or body hair? +

No. Unlike oral minoxidil, this is applied only to the scalp and does not drive unwanted body-hair growth.

How do I use it? +

A few drops to the scalp at night, massaged in. That's it. Consistency for the full 90-day follicle cycle is what moves the needle.

From "nothing works" to "I can finally feel it."

"Came off the pill two years ago and my hair started falling out in the shower. Biotin did nothing. By week five on rebloom the drain finally looked different. I actually cried."

Priya N. — Verified

"I've had PCOS since I was 19. Accepted the weight, the chin hairs, all of it. The hair was the one I couldn't accept. Three months in and my part looks like it did before."

Danielle R. — Verified

"My doctor told me to just accept it. I tried four supplements before this. rebloom is the only thing that has actually moved the needle."

Rachel D. — Verified

"28 years old and studying my scalp in the car mirror every morning. Baby hairs along my hairline by month three. I didn't think that was possible for me."

Karen M. — Verified
The Final Word

Every day you wait is another day DHT keeps choking the follicle.

The good news is follicles are stubborn. They don't die easily — they shrink when DHT keeps attacking, and they wake back up when you finally give the scalp what it needs.

Biotin was never going to do that, because biotin is a vitamin and you're fighting a hormone. Your hair can come back. But it needs you to treat the thing actually causing the loss.
