Targets:

1 Exosome, NAD+ & Triple PDRN Hair & Scalp Care Shampoo
Deep structural repair and targeted moisture therapy post-cleanse. Restructures keratin bonds.
Anti-Hair-Loss Care with Exosome & PDRN
Exosome and PDRN, among biotechnology's most advanced ingredients, are delivered to the scalp to trigger cellular renewal starting from the roots. Powered by NAD+ and Caffeine, this formula deeply stimulates roots weakened, thinning, or receding due to genetic or environmental factors — supporting denser, fuller hair with a stronger hold.
Strengthening from Root to Tip
Supported by a Peptide, Biotin, and B-Vitamin Complex, the formula strengthens the internal structure and bonds of weakening, thinning strands. It helps prevent breakage at the root, protecting the scalp throughout the day for hair that looks more voluminous, thicker, and more resilient.
Direct Root Stimulation with the Specialized Brush Applicator
The product's integrated brush applicator delivers active ingredients straight to roots affected by hair loss. The massaging action on the scalp triggers circulation, allowing for maximum absorption of actives — providing clean, refreshed, and strengthening care all day without oiliness, stickiness, or weight.
Exosome
A next-generation biotechnology against hair loss and thinning, exosomes trigger cellular communication to stimulate weakening roots. They help create a strong foundation that supports the growth of new, resilient hair in thinning areas.
PDRN
A molecular powerhouse that helps roots anchor more securely to the scalp, PDRN renews the scalp barrier and delivers repair at the cellular level. It helps heal sensitized tissue prone to shedding, helping to secure roots in place.
NAD+ & Caffeine
Instantly triggers microcirculation — the most critical factor in fighting hair loss. By maximizing the flow of nutrients, oxygen, and energy to the roots, it helps weakened roots grow back stronger.
Peptide, Biotin & Keratin Complex
A protein and vitamin complex that thickens thinning, easily-breaking strands from root to tip. It strengthens hair bonds to help reduce breakage and shedding, giving hair a fuller, more voluminous look.
