Instructions for use

Shake before use. Apply once daily, to wet or dry scalp, about one or two dropper squeezes or more (about 0.8 mL to 1.6 mL). Part your hair and apply directly to the scalp, especially in the areas that are thinning. The measurement does not need to be exact; apply enough serum for good coverage. Massage in with fingertips, then wash hands well. Since hair growing cycles can take at least 1 to 4 months, it may take a while to notice beneficial effects. Remember that results from any legitimately effective hair densifying regimen can take between 6-12 months to begin, and several years before optimal results are reached since the anagen or growing phase of the hair is at least two years in duration.

Use in addition to, and before applying, your regular styling products or products such as minoxidil. Discontinue use if irritation develops. For external use only. Store at room temperature.

Do not use the optional Triaminodil vial if you are pregnant or breastfeeding.

Dispensers

The package comes with a glass medicine dropper applicator. We also offer alternative dispensers: a fine-mist sprayer and a lotion-style treatment pump. The fine-mist sprayer is better for large coverage areas, for even disbursal of the serum. The treatment pump is better for specific thinning treatment areas/spot treatment, and to avoid applying to hair (by targeting only the scalp); the dropper acts similarly. Select any optional add-on dispenser(s) above.

The nominal output for the optional fine mist sprayer is 0.16 cc (mL), so that equals about 6 sprays per 1.0 mL.

The nominal output for the optional treatment pump dispenser is 190 MCL (microliters) or 0.19 mL. Therefore about 5 pumps would be the equivalent of 1.0 mL.

CUSTOMIZE YOUR SERUM with multiple add-in booster vials
DHT Thwart vial

DHT Thwart vial

Powerful new booster actives

OPTIONAL DHT THWART ADVANCED ACTIVES

This extra ingredients vial is optional for those who specifically want to target DHT in the scalp, with the latest cutting-edge actives. Ideal for addressing scalp hair loss but not for facial or body hair, which requires DHT to thrive.

This newest revolutionary booster vial contains four remarkable and powerful new ingredients: RootBioTec hairy basil root culture; Yerba Santa Bioferment; Fullerenes; and Nonanedioic Acid. Cutting-edge technology includes:

  • RootBioTec HW, a "hairy root culture" molecule from a type of herbal Basil. RootBioTec HW helps reduce hair loss by targeting the inhibition of 5a reductase activity (the enzyme that converts testosterone into 5a-dihydrotestosterone, a major cause of hair loss), and the stimulation of dermal papilla cells.
  • Yerba Santa Bioferment targets both hair loss and greying with high concentrations of sterubin and other novel flavonoids.
  • Fullerenes are a novel (and expensive) carbon structure, also known as "buckeyballs" or "Buckminsterfullerenes." They are typically neither water-soluble nor oil-soluble, but we've found a way around that. They penetrate into hair and bulb for robust benefits, including antioxidant protection inside the hair shaft itself. With this permeability, fullerenes even protect hair dye from fading by UV damage, and inhibit cysteic acid production by UV irradiation. Our version also improves and retains hair sheen.
  • Nonanedioic Acid, a linear saturated dicarboxylic azelaic acid derived from grains such as barley, targets the inhibition of 5a-reductase. This process works by tricking 5-alpha-reductase to “swallow” the nonanedioic acid instead of free testosterone at the scalp.
Triaminodil vial

Triaminodil vial

"Chemical cousin" of minoxidil

OPTIONAL TRIAMINODIL® 5.0% (PYRROLIDINYL DIAMINOPYRIMIDINE OXIDE)

A chemical cousin of minoxidil (which is a Pyrimidinediamine Piperidinyl Oxide), PDPO has been shown to act similarly on the appearance of hair, but without many of the side effects, possibly because of its lower molecular weight. This ingredient is in the "cosmetic" category. Triaminodil is shown to stimulate & extend the appearance of the anagen phase of hair follicles, and help prevent the hardening of the hair shaft and collagen buildup around it. It is believed to target the opening of ion channels. Nanoxidil™ and Aminexil™ are other trade names for this type of ingredient.

This extra ingredient vial, meant to be added to the included RevivHair Max Hair Stimulating Serum bottle before use, is optional for those users who want to target growth-regulating effects. This optional vial is a customer add-on for a small additional fee. Click the checkbox above to add it to your product selection.

REV booster vial

REV booster vial

Grey reverse with Darkenyl + Greyverse

OPTIONAL REVIVHAIR REV GREY HAIR REVERSAL BOOSTER VIAL

This extra ingredients vial, meant to be added to the included RevivHair Max Serum bottle before use, is optional for those users who also want to target grey hair reversal - without dyes or colorants!

RevivHair REV booster vial revives the appearance of natural pigment without having to resort to harsh dyes. Revolutionary new peptides draw natural hair pigment out from the roots without the use of colorants, simultaneously stimulating the hair bulb to produce hair that appears thicker, denser, longer. Regardless of gender, hair type, or hair color.

Into the RevivHair Max bottle, the REV vial ingredients yields 2.0% Greyverse + 1.0% Darkenyl (novel anti-greying ingredients) — the strongest recommended levels for clinically proven hair repigmentation action.

PRODUCT SPECIFICATIONS

Fragrance-free, minoxidil-free, and quick-drying, this unisex serum is a light, almost clear, formulation safe for all hair colors, hair types, and ethnicities. It contains novel polymers that also instantly thicken and help moisturize the hair shaft, without adding too much weight. And no oiliness or greasiness. Safe for color-treated hair. It also works on beard and sideburn areas!

The percentage of Redensyl in RevivHair Max is at its most potent: 5% maximum strength, and its RCP actives are liposomal for timed-release. The total concentration of active technologies in the formula is over 80%.

If you use minoxidil, RevivHair Max can be used in addition, and the order of application isn't important. Many customers apply both, but if you don't like the side effects of minoxidil, you may prefer to use RevivHair Max by itself.

RevivHair Max can be used with scalp dermarolling / microneedling, as long as the strength is in the "cosmetic" category (less than about 0.5 mm). For medical microneedling, we recommend waiting 12 to 24 hours before applying RevivHair Max.

The 60 mL bottle should last between 37 to 75 days (about one to two dropper bulb squeezes, 0.8 mL to 1.6mL, once daily). The measurement does not need to be exact, and we recommend applying enough serum for good coverage. For some, this might mean using more product than the instructions specify.

DISPENSERS

The package comes with a glass medicine dropper applicator. We also offer alternative dispensers, like a fine-mist sprayer and a lotion-style treatment pump.

The fine-mist sprayer is better for large coverage areas, for even disbursal of the serum. The treatment pump is better for specific thinning treatment areas/spot treatment, and to avoid applying to hair (by targeting only the scalp); the dropper acts similarly. Select any optional add-on dispenser(s) above.

The nominal output for the optional treatment pump dispenser is 190 MCL (Microliters) or 0.19 mL. Therefore about 5 pumps would be the equivalent of 1.0 mL. The nominal output for the optional fine mist sprayer is 0.16 cc (mL), so that equals about 6 sprays per 1.0 mL.

CUSTOMER REVIEWS

What OUR CUSTOMERS SAY

FAQ

You asked, answered

What is Reviv Serums and what makes your products different?

Reviv Serums creates breakthrough serums for hair, skin, lashes, and brows that combine cutting-edge cosmetic science with exceptional value. Our formulations match or exceed the potency of professional and physician-dispensed brands — but at rare direct-to-consumer pricing.

Each product is crafted by experts in advanced cosmetic chemistry, using clinically tested yet new-to-market actives that deliver visible, real-world results. From fuller hair to smoother skin, our mission is to bring “leapfrog” innovation directly to you — without the inflated markups or middlemen.

Do you ship internationally?

Yes! We offer free U.S. shipping on all orders, with no minimum purchase required. Orders are typically processed within 1–3 business days, and standard delivery takes about 2–8 business days depending on your location.

We also ship to many countries worldwide — including to the EU, UK, Australia, New Zealand, and Singapore for a flat-rate of $10 USD. International orders generally arrive within 7–10 business days, although customs and local delivery times can occasionally extend this window slightly.

Is it safe to order from your website?

Absolutely. RevivSerums.com uses advanced SSL encryption to secure every transaction from checkout to confirmation. This ensures your data — including payment information — is transmitted safely and cannot be intercepted or viewed by anyone else.

We also partner with trusted third-party providers for fraud protection and chargeback prevention. Ordering online is the safest and fastest way to place your order, and we never store your full credit card details on our servers.

What is your return or refund policy?

We want you to love your results. If for any reason you’re not completely satisfied, you can return your product within 30 days of receipt for a refund or exchange. Simply contact our support team to receive a return authorization and instructions.

Returned items must be in their original packaging and no more than about 50% used. Once we receive and inspect your return, refunds are processed back to your original payment method, typically within 10 business days. Shipping fees are non-refundable.

Are your products cruelty-free and safe?

Yes — all RevivSerums products are cruelty-free and made in the USA under strict manufacturing standards. We source high-quality ingredients and verify purity through independent third-party lab testing. Each batch is formulated to meet GMP-level (Good Manufacturing Practice) quality standards.

Our products are cosmetic, not pharmaceutical. They’re designed to cleanse, beautify, and enhance the appearance of hair and skin, not to diagnose or treat any medical condition. Individual results may vary depending on your skin and hair type.

Can I combine multiple serums in my routine?

Yes, absolutely. Each Reviv Serums product is formulated to complement others in our range, allowing you to create a complete self-care or anti-aging regimen. Many customers layer or alternate serums to address multiple goals — for example, using RevivHair Max Serum with RevivScalp Masque for hair, or pairing TelomErase with Revivinol for facial rejuvenation. All our hair serums can be layered together, and all our skin serums can as well.

Our team designed these formulas to be compatible, lightweight, and easy to integrate into your daily routine. You can safely mix and match based on your personal needs or focus areas without compromising results.

What results can I expect, and how long will it take?

Most customers begin to notice improvements within 3–8 weeks of consistent use, depending on the product and individual factors like skin type, hair cycle, or age. Serums for skin tend to show faster results, while hair products work gradually as follicles renew.

Consistency is key — results build with daily use, and long-term use leads to better visible outcomes. Always follow product directions and use as part of your regular routine for best results.

Are your ingredients clinically tested?

Yes. Every Reviv Serums formulation includes scientifically validated ingredients, many of which have been tested in clinical trials for safety and performance. We use actives like Redensyl®, Capixyl™, and Sytenol-A™, which are well-documented for their cosmetic benefits.

We publish transparent ingredient lists for each product on our site, so you can see exactly what you’re applying. If you have allergies or sensitivities, we recommend reviewing the full list and consulting a dermatologist before use.

How can I contact your support team?

We’re always happy to help. The fastest way to reach us is through the contact form on our website or by emailing [Support Email]. You can also use our live chat feature during business hours for quick assistance.

If you prefer to call, our toll-free U.S. number is 1-844-REVIVSERUMS. Our friendly team is based in San Francisco and typically responds to messages within 24 hours on business days.
