BENEFITS

Rennora's 38-ingredient formula blocks DHT at the scalp, wakes dormant follicles, and rebuilds density at the hairline, crown, and beard. No harsh chemicals, no drugs, no prescription. Made for Black men and the hair loss patterns we actually deal with. Every bottle is 1 ounce and lasts about 30 days. The full protocol is 3 bottles.

HOW IS THIS OIL ANY DIFFERENT?

Made for Black men, by a Black-owned brand. Rennora was built for our hair, our texture, and the hair loss we actually deal with: the pushed-back hairline, the thinning crown, the patchy beard. It works by stopping hair loss at the root cause. Most products just moisturize the surface. Rennora blocks the DHT that shrinks your follicles and calms the inflammation that blocks blood flow, so dormant follicles can wake back up and grow again.

WHAT ARE THE INGREDIENTS?

Castor Oil, Soybean, Grape Seed Oil, Olive Oil, Chili Oil, Argan Oil, Tea Tree, Amla, Bhringraj, Stinging Nettle, Peppermint, Mustard Seed, Basil, Sesame Seed, Rosemary, Sage, Thyme, Aloe, Garlic Seed, Onion Seed, Pygeum, Biotin, Ginkgo Biloba, Black Tea, Neem, Aritha, Calendula, Chamomile, Dandelion, Lemongrass, Saw Palmetto, Ginseng, Fenugreek, Ginger Root, Gotu Kola, Hibiscus, Lavender, Horsetail.

Every bottle is 1 ounce and lasts about 30 days. 

HOW TO USE THIS SERUM?

Apply to the hairline, crown, or beard patches daily, morning or night. Massage gently for 2 to 3 minutes with your fingertips, and leave in. No rinsing. The protocol is 90 days of daily use. Skipping days resets the clock.

120-DAY GUARANTEE 

(THE PROTOCOL + 30 DAYS)

Run the full 90-day protocol. If you don't see the difference, you have a 30-day cushion beyond it to get every dollar back.

This is the schedule. Screenshot it. Every checkpoint has a job for the follicle and a job for you.

DAy 14

Shedding slows

Title

Inflammation calmed. Count the drain. Fewer strands is the first win.

DAY 30

Stubble in the thin spots

Title

Fingertip check along the hairline and crown. Touch finds it before the mirror does.

DAY 60

The barber notices

Title

The line holds the fade. Thin spots filling. He'll say something before you do.

DAY 90

The Transformation

Title

Line-up photo day. Your before and after moment.

You're not alone. And you're not stuck.

The Real Reason Your Hair Stopped Growing

your follicles aren't dead. they're starving.

Most growth oils only moisturize the strand. Rennora targets what's actually happening at the root.

01 - THE TRIGGER

DHT Floods the Follicle

The same hormone that gave you your beard turns on your hairline with age, shrinking follicles at the temples and crown first. Tension from braids, durags, and tight fades squeezes from the other side.

02 - THE BLOCKAGE

Blood

Flow Cut Off

Shrunken, inflamed tissue strangles the tiny capillaries that feed each follicle. No nutrients in. No oxygen in. Your follicle goes dormant. But it's still alive.

03 - THE REVIVAL

Rennora

Wakes It Up

Saw palmetto, pygeum, and nettle block DHT at the scalp — no pill, no prescription. Rosemary and peppermint restore blood flow. 38 plant compounds total, so your follicles can finally do what they were built to do.

Why 90 Days? 

 

Because that's how long the biology takes. Weeks 1 and 2 calm the inflammation. Weeks 3 to 8 let reopened blood flow wake the follicle. Weeks 8 to 12 push the new strand past the scalp. The protocol isn't patience for its own sake. It's the follicle's actual schedule.

Questions Answered

the most common questions before buying.

Why 90 days? Other products say 2 weeks.

Anything that changes your hair in 2 weeks is coating the strand, not growing it. A follicle takes 8 to 12 weeks to wake, repair, and push a new strand past the scalp. We'd rather tell you the truth and be there at day 90.

What if I miss a day?

One missed day won't erase your progress, but the follicle responds to consistency, and skipping days resets the clock. If remembering refills is the hard part, the subscription ships every 28 days so the protocol never gaps.

Will it work on my hairline? My crown?

The hairline and temples usually answer first — feel for stubble around day 30. The crown follows around day 60, because those follicles have been dormant longer. That's exactly why the protocol runs 90 days, not 30.

Does it work on beards?

Same follicle biology. Apply it to the patchy areas on the same daily schedule. Beard follicles are usually younger than a receded hairline's, so they often answer faster.

Is it safe with waves, braids, locs, durags, and dye?

Yes. The formula is 100% drug-free and plant-based, applied to the scalp, not the strand. It works under durags, braids, and locs, and it won't interfere with dye or your brush routine.

How long does a bottle last?

About 30 days of daily use. That's the arithmetic behind the 3-bottle protocol: one bottle per month, three months to your photo day.

Is this just the women's bottle relabeled?

Same core follicle science, formulated for the patterns men fight: the hairline and crown, driven harder by DHT. That's why the DHT blockers — saw palmetto, pygeum, nettle — carry the formula here, at the scalp, with no pill and no prescription.

How does the 120-day guarantee actually work?

Run the full 90-day protocol. If you don't see the difference, you have a 30-day cushion beyond it, all the way to day 120, to get your money back. Just email us support@rennorabeauty.com
