We offer a 150-day money-back guarantee on all unused and unopened serums. If you change your mind for any reason, simply contact us within 150 days of delivery and we’ll issue a full refund — no questions asked.

Due to strict hygiene and safety protocols, we’re unable to accept returns of any opened or slightly used serums. We also cannot offer refunds on dermarollers, as they are considered personal care tools.

Our guarantee is designed to give you complete confidence in your purchase — while upholding the highest standards of product integrity and safety.

We simply ask for honesty. This guarantee exists because we’ve seen what’s possible when the right ingredients meet consistency. 

As long as your serums are unused and unopened, you’re eligible for a full refund within 150 days of delivery. We simply can’t accept opened or slightly used bottles, since we uphold strict hygiene standards and never resell returned product.

No forms. No hoops. Just a thoughtful return policy designed with your trust (and your scalp) in mind.

We reserve the right to approve or deny any guarantee request at our sole discretion. Abuse of this policy may result in ineligibility for future claims. If your request is approved, we’ll ship you a fresh 3-pack completely on us—free shipping included. No fine print. No loopholes. Just our way of standing behind what we make.

Because we didn’t rush this. The Hair Multiplier was born out from years of development and frustration from an industry full of empty promises. Our formulas are backed by clinical testing, 95% organic ingredients, and real results from real women. You deserve more than a promise — you deserve something that actually works.

The Hair Multiplier isn’t just another serum—it’s a return to what actually works. While most treatments rely on synthetic compounds that disrupt your scalp’s balance, our formula is guided by generations of Swiss tradition and designed in harmony with your biology.

We use 95% organic ingredients that your scalp recognizes—not resists—including our signature Swiss 7-Stem Complex™, organic caffeine extract, and bio-fermented hyaluronic acid. It’s hormone-disruptor free, clinically tested, and rooted in the belief that real change doesn’t come from force—it comes from alignment.

We don’t promise overnight miracles. But with consistent daily use, most women see reduced shedding, stronger strands, and baby hairs emerging around the 90-day mark. That’s why we offer our industry-first 90-Day Baby Hair Guarantee—because we believe results should be both natural and visible.

No. The Hair Multiplier was designed for daily use—even for women who wash only a few times a week. It absorbs quickly into the scalp without leaving a greasy residue and is formulated without heavy oils or silicones. If your scalp tends to get oily, we recommend applying it at night so it works while you sleep.

Yes, you can absolutely use The Hair Multiplier if you have dandruff. The key is to apply the serum directly to your scalp and ensure consistent, proper application. For the best results, follow these tips:

• Apply the serum to a clean scalp, ideally after washing and towel- or blow-drying your hair.
• Use the serum at night to align with your body’s natural restorative process.
• Massage the serum into your scalp with your fingertips (not nails) to boost circulation and improve absorption.
  

Taking these extra steps will help maximize the benefits of the serum and promote healthier hair growth.

Yes. The Hair Multiplier is safe for color-treated, bleached, or chemically processed hair. In fact, many of our customers use it to restore strength and density after years of coloring or damage. The formula is free from harsh chemicals and contains only clean, non-stripping ingredients designed to support scalp health and stimulate natural growth—regardless of your hair’s history.

Hair grows in natural 90-day cycles, which is why most women begin to notice new baby hairs around the 3-month mark. In clinical usage, the most visible results appeared in women who applied the serum daily for at least 90 days. For best results, we recommend consistent, uninterrupted use—because real progress doesn’t happen overnight. It happens with rhythm.

We always recommend speaking with your doctor before using any new product during pregnancy or breastfeeding. While The Hair Multiplier is free from hormones, minoxidil, or prescription drugs — and formulated with gentle, plant-based ingredients — it does contain caffeine. Everyone’s body is different, so it’s best to share our full ingredient list with your healthcare provider to determine what’s right for you.

Many women experience postpartum shedding, and The Hair Multiplier was designed to help support hair health during that recovery phase.

Yes. The Hair Multiplier was specifically formulated with sensitive scalps in mind. It’s 95% organic, free from hormone-disrupting chemicals, and contains no sulfates, silicones, or synthetic fragrances. Every ingredient is chosen for its purity, gentleness, and harmony with the scalp’s natural biology. That said, if you have known sensitivities or active scalp conditions, we always recommend doing a patch test before full use.

For best results, apply twice daily—ideally on a clean, dry scalp. Part your hair in sections and use one full dropper to apply directly to the scalp, focusing on areas of concern. Gently massage in with your fingertips or use a scalp massager to stimulate absorption. On days you use our dermaroller (3x/week), apply the serum after rolling. Skip serum application only on roller days if your scalp feels sensitive.

Consistency is key—think of it as a daily ritual that supports your scalp’s natural growth cycle.

Use the dermaroller 3 times per week on a clean, dry scalp. Gently roll it back and forth over areas of concern—front hairline, temples, crown—for about 5 minutes total. Apply light, even pressure without dragging.

On dermaroller days, do not apply The Hair Multiplier immediately before or after. Instead, allow your scalp to rest and resume serum application the following day. This helps avoid irritation while still supporting consistent results.

For hygiene, always disinfect your dermaroller with rubbing alcohol before and after use.

Each bottle is designed to last 30 days with consistent daily use, when applied as directed to the scalp. For best results, we recommend using it twice daily—either on its own or alternating with dermarolling days.

Our community includes women of all ages—from postpartum to postmenopause—who have seen real, visible results using The Hair Multiplier. If you scroll through our reviews, you’ll find stories from customers navigating everything from hormonal shifts to age-related thinning.

For medical conditions like alopecia, Hashimoto’s, or other health-related concerns, we always recommend speaking with your healthcare provider before starting any new product.

Like any hair serum product, the results from our serums will last as long as you continue using them.

The good news is that for hair The Hair Multiplier, the enhanced hair growth cycle lasts longer, meaning it may take a few months for your hair to gradually return to its natural state after discontinuing use.

Yes—while The Hair Multiplier was designed with women’s biology in mind, many men have used it and shared excellent results. The core mechanisms of hair growth and scalp health are shared across genders, and our formula works by supporting the root environment rather than relying on hormone-altering ingredients. That said, it’s especially well-suited for those looking for a gentle, non-irritating, and hormone-disruptor-free approach to regrowth.
