INNOVATIVE MICRONEEDLE REPAIR
A leave-in treatment with an intensive deep-delivery system specifically targets advanced, stubborn thinning to aggressively reduce severe shedding right from the root. Exclusive technology creates deep micro-pathways, driving Biotin, Peptides, Caffeine, and Brewer's Yeast Extract straight down to the roots.
MAXIMIZED HAIR DENSITY
That intense, active tingle is the physical proof of our maximum-strength formula successfully penetrating deep into the scalp layers to ignite powerful growth. By unleashing an amplified surge of essential nutrients directly into weak follicles, it actively forces all hair types to achieve a visibly thicker, fuller, and significantly denser look.
CLINICAL-GRADE SCALP RECOVERY
Trusted by salon professionals for its clinical-grade potency, this serum brings premium, high-concentration scalp therapy straight to your home. It drastically accelerates scalp rejuvenation and elasticity to firmly grip each strand at the root, building a highly resilient foundation that actively fights severe thinning.
THE ULTIMATE OVERNIGHT TREATMENT (2-3X A WEEK)
As a concentrated overnight booster rather than a daily treatment, use this powerful formula just 2 to 3 times a week before bed. It absorbs flawlessly without leaving any heavy buildup or greasy residue, letting the maximum-strength microneedling science work seamlessly while you sleep to completely revitalize your hair.

Step 1. Timing & Prep: Use as an intensive treatment on a clean scalp. It can be applied after shampooing on either a damp or a completely dry scalp, ideally as part of your evening hair care routine.
Step 2. Dispense: Unlock the dispenser and pump an appropriate amount (about 2 to 3 drops or 1 light pump) directly onto your fingers or onto the targeted areas.
Step 3. Apply: Apply the high-concentration formula directly onto your advanced or stubborn areas of concern, such as a widening parting line, a thinning crown, or a receding hairline.
Step 4. Massage & Absorb: Gently massage the serum into your scalp using clean fingertips (moving in small circles or a Z-shape). The fast-absorbing formula penetrates deeply to deliver nutrients straight to the hair roots without leaving any greasy residue.
Step 5. Frequency & Leave-In: Do not rinse or wash it out; this is a highly concentrated leave-in treatment. Use it consistently 2 to 3 times a week for intensive care (or daily every evening for aggressive treatment) to maximize follicle health and root strength.
Pro Tip: Because this is an advanced, high-intensity formula, you will feel a more noticeable, refreshing pricking or tingling sensation compared to the 400 version. This is completely normal and indicates that the 1.6 million high-purity bio-microneedles (Spioxyl™) are successfully creating deep pathways to deliver active nutrients deep into your roots.

It is an intensive, concentrated nighttime scalp care shot infused with a massive 1.6 million ultra-fine Spioxyl™ microneedles. It is formulated to deliver active hair-growth ingredients deep into 8 layers of the scalp while you sleep.
The primary difference is the concentration and frequency of use. React 400 contains 220,000 spicules and is designed as a gentle, everyday scalp primer. React 800 is a highly intensive treatment loaded with 1.6 million spicules. Because it is so concentrated, React 800 is only meant to be used 2 to 3 times a week at night.
They are designed to create the ultimate day-and-night microneedling routine! Using the React 400 provides gentle, daily scalp activation, while the React 800 steps in 2-3 times a week for high-intensity overnight repair. Together, they continuously keep deep scalp pathways open for maximum nutrient absorption, strengthening your hair from the root around the clock.
Yes. Because React 800 contains over seven times the amount of bio-microneedles compared to the 400, the tingling sensation will be more intense. This physical sensation is a normal, positive indicator that the highly concentrated nutrients are being actively pushed deep into your hair roots.
