THE HUMAN HAIR CYCLE

Your Hair Grows In 3 Month Cycles

Real change requires one full cycle. This is why The Hair Multiplier® was made around the science of how hair actually grows.

Hair cycle illustration Hair cycle illustration mobile
Month 1 Reset & Rebalance

The first month is quiet on the surface, but it's when the foundation gets set. Years of buildup, inflammation, and DHT-driven stress have left your scalp in survival mode. Applying 2mL each evening, the Awakening dose, saturates the scalp with Swiss 7-Stem Concentrate® and calms inflammation while signaling shedding follicles back into the anagen growth phase. Visible changes are minimal. The biological work is happening beneath the surface.

Month 2 New Density Begins

The work beneath the surface starts to show. Baby hairs emerge along your part line. Strands at the temples feel sturdier. Shedding has stopped. With the foundation set, 1mL nightly is now enough to keep Swiss 7-Stem Concentrate® strengthening each follicle and extending its time in the active anagen phase, the only phase where hair actually grows. Density quietly returns.

Month 3 Extended Growth & Length

By month three, your hair feels and looks noticeably different. Existing strands are thicker, fuller, denser at the root. Hairs that were shedding in Month 1 have re-entered anagen and are emerging as new length. One full cycle is complete. Density has returned to the root and mid-lengths — and with every cycle that follows, the fullness travels further down the strand, toward your ends.

"My hair used to stay around bra-strap length, but now it’s growing longer and looks healthier. I truly feel beautiful with my natural hair again."

I started with one bottle, and after that I subscribed to receive a refill every three months. I am now finishing my third bottle after about two and a half months, and I can’t wait for my next refill to arrive. I’ve noticed such a beautiful difference in my hair. It feels softer, shinier, and much stronger than before. I also feel like my hair is growing faster.

It feels softer, shinier, and much stronger than before. I also feel like my hair is growing faster. For many years I had blonde hair because I was covering my grey hair. Recently I decided to return to my natural color, and this product has been part of that journey. My hair used to stay around bra-strap length, but now it’s growing longer and looks healthier. I truly feel beautiful with my natural hair again. I’m excited to continue this journey and keep using this brand.

Results: Gained length, hair feels softer and stronger

"I'm so happy I didn't quit...my hair is noticeably thicker"

It actually works!!! This is the first time in my life I am writing a review about something because THIS WORKS. Not sponsored and not a paid review. These are around 4 months apart. My sides have nearly filled in plus my hair is noticeably thicker when I tie it up or run my fingers through it. Consistency is KEY, about 80% of the new hairs you're seeing didn't even appear until early month 3.

Frequently Asked

Questions

Most women notice less shedding within the first few weeks. Followed by softer, healthier-feeling hair by month one. Baby hairs and added density typically become visible by month two. From month three, visible length and ongoing growth can start to show.

Results compound. The women who see the most significant transformation are the ones who stay consistent, supporting their hair through its ongoing natural growth cycle.

When application is inconsistent, build-up and oxidative stress return. This signals to the follicle that the scalp environment isn't suited to growth. Hair transitions out of active growth and into resting and shedding.

Most hair growth products coat the strand or force growth with synthetic ingredients. The Hair Multiplier works differently. It targets the scalp environment and follicle directly, restoring the conditions your hair needs for healthy ongoing growth. This is why women who have tried everything else are finally seeing results with The Hair Multiplier.

Yes. Apply the serum directly to your scalp every evening, focusing on the areas where you'd like to encourage new growth.

Because extensions can place extra tension on fragile strands, we recommend gentle, low-tension styles while your hair strengthens. New hair is at its most delicate as it grows, so treat it with care.

No. The Hair Multiplier's weightless consistency absorbs into the scalp in seconds and leaves behind no residue. This means you can apply the formula daily without washing more often or hair becoming heavy or oily.

Yes. The Hair Multiplier® is ideal for those with compromised hair. Formulated with pure alpine botanicals, selected for their strengthening and restorative properties, its bioactive ingredients repair weakened strands, revitalize dormant follicles, and restore a healthy growth environment, leading to reduced breakage and revealing visibly healthier hair.

The Hair Multiplier® is fragrance-free and contains no synthetic perfumes to prevent scalp irritation.

Some women notice a slight, temporary increase in shedding in the first few weeks. This is usually a small portion of resting hairs completing their natural cycle and releasing, making room for new, stronger strands to form.

Meanwhile, the rest of your hair continues to strengthen and thicken in its active growth phase. Think of it as a gentle reset of the growth cycle: the hairs that release are gradually replaced by healthier, more resilient ones.

The Hair Multiplier® is plant-based and non-hormonal, formulated without minoxidil, finasteride, or hormonal actives. Many of our customers first come to us during the postpartum stage, when shedding is especially common, and use it to support their hair through that transition. That said, every pregnancy is different, and we can't make individual medical recommendations. If you're pregnant, breastfeeding, taking medication, or managing a health condition, please check with your doctor before use.

Shocked, in the best way!
I have been using Le Jardin for about two months now and am shocked by how much thicker my hair has become and how much faster it is growing. I had my hair done in February and generally I can go 4-5 months before having my hair highlighted again because my hair grows so slowly and you usually can't see the root fully grow out until around that 4 month mark. However, I have had to move my June appointment up because my hair has grown so fast! Even my boyfriend has commented on how thick it feels and is starting to look. I had a lot of doubts starting out because I have tried so many things so I did not take a before photo but i am posting how much growth I have had in length! I started using Le Jardin at the beginning of February, right after my last highlight appointment, and the photo was taken today (4/8/26). Will continue to use and update more!

It’s Worth the Investment, Ladies!
Let me tell you what a journey my hair loss has been! Post-divorce my hair started falling out, and vitamins and proper nutrition alone weren’t cutting it. A year later and my hair wasn’t regrowing properly. I decided to give this serum a try and I’m SO glad I did! I use the product 2x per day - morning and night. I’ll use the micro needling roller once per week. The one downside is I felt like the bottle didn’t quite last a month, but based on my results it’s worth the investment! Don’t hesitate to try it. Before and after photos attached. Good luck with your hair journey!! Let me tell you what a journey my hair loss has been!

Less shedding, more volume
By month two the drain situation had improved a lot. Hair along my part is visibly fuller now. Simple as that. By month two the drain situation had improved a lot. Hair along my part is visibly fuller now. Simple as that.
