Before and After

FAQ

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.

Because of its high intensity, you only need to use it 2 to 3 times a week as a nighttime treatment.

Im in my 40s and

"Im in my 40s and recently started noticing that my hair wasnt as full as it used to be, especially around the sides. I came across Spioxyl and gave it a shot after reading about the spicule technology and clinical results. It feels amazing when you apply itcool, clean, and super light. I love that theres no sticky residue. After a few weeks, my scalp feels healthier, and Ive noticed stronger, thicker roots. Its honestly become a self-care ritual I look forward to every day."

"To be honest, I didnt have super high expectations when I bought this, but I figured it couldnt hurt. Im SO glad I tried it. Within a week, my scalp just felt healthierless itchy, less tight, and way less flaky. And now, almost a month in, my hair looks fuller at the roots. Ive been applying it to my part line and the sides of my head, and its definitely made a difference. Feels like Im actually doing something good for my scalp, not just covering up a problem."

"Its easy to use, and I love that I can apply it directly where I want. After use, I could really feel it absorbing deeply not just on the surface, but way down into the scalp with an immediate cooling effect. Now I get why they say it penetrates 8 scalp layers with good absorption."

800 spicules sounds intense�� but

"800 spicules sounds intense�� but my scalp LOVES it I got this scalp ampoule after hearing it packs 800 spicules (wild, right?) and has ingredients that are clinically proven to wake up those sleepy hair follicles. Supposedly it goes all the way down to the 8th layer of your scalp with over 300% better absorption?which honestly sounded too good not to try. Surprisingly, even with all those spicules, it didn��t sting or irritate my scalp at all. I applied it with my bare hands and felt zero discomfort (though of course, your experience might vary). What I did feel was this super refreshing, cooling sensation that makes it a treat to use every day. Since I started seen way less hair in the drain after washing, and I get noticeably more volume when I blow-dry. It��s also compact and really easy to use perfect for everyday scalp care on the go. The results speak for themselves. I��m already planning to repurchase."
