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.

HOW IS THIS OIL ANY DIFFERENT?

Most oils only moisturize the strand. Rennora targets the root cause — follicle inflammation. Our formula penetrates the scalp to reduce inflammation, restore blood flow, and reactivate dormant follicles that other products simply can't reach.

HOW TO USE THIS OIL?

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.

INGREDIENTS

Jamaican Black Castor Oil, Peppermint Oil, Rosemary Oil, Biotin Complex, Vitamin E, Argan Oil, Tea Tree Oil, Black Seed Oil, Horsetail Extract, Saw Palmetto, Nettle Root Extract, and 27 additional clinically studied botanicals.

SHIPPING & RETURNS

Free shipping on all orders over $60. Orders ship from our Atlanta facility within 48 hours. Domestic delivery in 3–5 business days. Not satisfied? We offer a full 120-day money-back guarantee — no return required.

With so many fakes flooding the market, Rennora's Oil stood out as the purest we tested. It shows proven efficacy in supporting scalp health, strengthening follicles, and promoting visibly thicker hair growth, including visible improvements along thinning edges and alopecia patches.

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.

Inside the Bottle

what's in the formula.

38 ingredients. Grouped by what they do for your hair. 

Job 01

Reduces scalp inflammation

● Calendula

 

● Tea Tree

 

● Chamomile

 

● Neem

Title

The inflammation calming the chronic swelling that's choking off your follicles.

Job 02

Restores blood flow

● Rosemary Oil

 

● Peppermint

 

● Ginger Root

 

● Ginkgo Biloba

Title

Rosemary alone has been clinically shown to perform comparably to 2% minoxidil.

Job 03

Blocks DHT at the root

● Saw Palmetto

 

● Pygeum

 

● Stinging Nettle

 

● Fenugreek

Title

DHT is the hormone that shrinks your follicles. These four shut it down without drugs.

Job 04

Stimulates new growth

● Bhringraj

 

● Amla

 

● Gotu Kola

 

● Biotin

Title

Ancient Ayurvedic actives that extend your hair's growth phase and wake dormant follicles.

The Real Reason Your Hair Stopped Growing

three minutes. three steps. that's it. 

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

01

Title

Apply directly to scalp

Use the precision dropper to place a few drops directly on your problem areas - edges, crown, thinning spots, or anywhere the scalp is visible.

Works between braids and under weaves

02

Title

Massage for 2-3 minutes

Use your fingertips in small circular motions. This activates blood flow and helps the 38 plant compounds penetrate down to the follicle.

No rinse. No mess. No residue.

03

Title

Repeat daily for 120 days

Morning or night, whichever fits your routine. Consistency is what wakes dormant follicles. Skipping days resets the clock - so make it a habit.

One bottle lasts ~30 days

The most common mistake: Women quit at day 30 because they don't see "miracle" results overnight. Your follicles need the full 90-120 day cycle to wake up, repair, and grow new strands. That's why we built the guarantee around 120 days - it gives the biology time to work.

Questions Answered

the most common questions before buying.

What if I've tried everything and nothing has worked?

Most of our customers tell us they tried everything before Rennora Hair Growth Serum... The reason those didn't work isn't that you didn't stick with them long enough. They never worked because they were never built to wake dormant follicles - they were built to condition healthy ones. Your follicles aren't dead, they're just inflamed and shut down. Rennora hair growth serum is the only formula targeting the inflammation first. And if it still doesn't work for you, the 120-day guarantee means you don't lose a dollar trying.

How long until I see results?

Many women see noticeable new growth within 2 to 4 weeks. The most dramatic before-and-after results - fully filled-in edges, regrown crowns, restored bald spots - typically come at the 90 to 120 day mark with consistent daily use. That's why we recommend the 4-bottle bundle: it matches the full guarantee window.

How long does each bottle last?

About one month. 

What are the ingredients?

While other products have just ONE ingredient, we have 38 natural, researched ingredients that can help stop hair loss. 

 

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

Can I buy Rennora Hair Growth Serum in stores?

Currently, Rennora Hair Growth Serum is available exclusively through our website. This allows us to ensure the highest quality and best pricing for our customers.

Is it safe to use with braids, weaves, or color-treated hair?

Yes. The serum is designed to be applied directly to the scalp - between braids, under weaves, or on natural hair. It's drug-free, sulfate-free, paraben-free, and gentle enough for daily use on color-treated and chemically processed hair.

How fast does it ship?

We ship from our Atlanta facility within 48 hours of your order, often same day. Tracking is emailed the moment your package leaves the warehouse. Most US orders arrive in 3 to 5 business days.

How do I get my money back if it doesn't work?

Email support@rennorabeauty.com within 120 days of receiving your order. You don't need to return anything. We refund the full purchase price to the same card you used. Real refunds, real fast. We're a small Atlanta team, not a faceless conglomerate.
