BENEFITS

Rennora's 38-ingredient formula wakes dormant follicles, strengthens weak strands, restores thinning edges and bald spots, and promotes visibly thicker, fuller hair — all without harsh chemicals or drugs. Made for black women and our unique hair issues. Every bottle is 1 ounce and lasts about 30 days.

HOW IS THIS OIL ANY DIFFERENT?

Made for Black women, by a Black-owned brand. Rennora was built for our hair, our texture, and the hair loss we actually deal with: edges, thinning, crown loss, and more. And it works by stopping hair loss at the root cause. Most products just moisturize the surface. Rennora goes deeper, calming the follicle inflammation that blocks blood flow and puts your follicles to sleep, so they 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 a small amount directly to the scalp 2–3 times per week. Part your hair in sections, massage gently for 2–3 minutes to stimulate circulation, and leave in. No rinsing required. For best results, use consistently for at least 8–12 weeks. Every bottle is 1 ounce and lasts about 30 days.

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

Follicle

Inflammation

Hormonal shifts, tension from braids and weaves, menopause, stress, and product buildup create chronic inflammation around your follicles.

02 - THE BLOCKAGE

Blood

Flow Cut Off

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

38 plant compounds reduce the inflammation, restore blood flow, block DHT, and extend the growth phase - 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 edges? My bald spot?

Edges usually respond first. Baby hairs typically show along the temples around day 30. Deeper areas like the crown and bald spots follow around day 60, because those follicles have been dormant longer. That's exactly why the protocol runs 90 days, not 30.

Is it safe with relaxers, color, braids, weaves, and wigs?

Yes. The formula is 100% drug-free and plant-based, and it's applied to the scalp, not the strand. It works under braids, locs, weaves, and wigs. One of our reviewers is a board certified trichologist who uses it with her color clients.

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.

What does it feel like on my scalp?

It absorbs with no greasy residue and no rinsing. Most women feel a light tingle in the first week. That's circulation returning, and it fades.

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
