- HOW TO USE
A slow-aging scalp & hair ritual powered by the ocean.
This two-step marine-powered duo helps restore youthful vitality to thinning or aging hair from root to tip.
The detoxifying shampoo clears scalp buildup, firms the roots, and boosts bounce, while the no-rinse elastic treatment smooths, plumps, and protects each strand with lasting hydration.
Formulated with upcycled seaweed extracts, Marine Filler Complex, and oyster peptides, this set visibly reduces signs of hair aging — including thinning, dullness, and loss of elasticity — while promoting fuller, shinier, and more resilient hair.
Clean, conscious, and backed by science.
Kelp & Seaweed Extract (Upcycled Seaweed from Korea)
Locally harvested, upcycled kelp and seaweed rich in marine minerals and alginic acid help purify scalp pores, restore elasticity, and strengthen thinning hair.
Marine Complex
A nutrient-rich blend of marine botanicals and minerals that replenishes moisture, soothes the scalp, and supports a healthy scalp barrier.
Oyster-Derived Peptide (from Tongyeong)
Hydrolyzed oyster protein from the clean waters of Tongyeong delivers amino acids to help improve scalp firmness and repair damaged hair.
PDRN from Laver (Seaweed DNA)
Extracted from Korean laver (seaweed), this DNA-based ingredient helps support scalp cell regeneration, improve elasticity, and reduce visible signs of aging.
Q1: How often should I use the Algae Therapy Shampoo and Treatment together?
A: The Algae Therapy Shampoo is gentle enough for daily cleansing, while the no-rinse Treatment can be used daily or as needed on towel-dried or dry hair. For optimal results, use the shampoo to detoxify the scalp and follow with the treatment to deeply hydrate and strengthen hair strands.
Q2: Is this duo suitable for sensitive, aging, or thinning hair?
A: Yes. Both products are formulated with marine minerals and upcycled seaweed to soothe sensitive scalps, support elasticity, and restore volume to thinning or aging hair without irritation.
Q3: Will the treatment or shampoo make my hair heavy or greasy?
A: Not at all. The shampoo creates a clean, balanced base, while the no-rinse treatment absorbs quickly with a lightweight texture—perfect even for fine or flat hair.
Q4: Can I use this duo on color-treated or chemically processed hair?
A: Absolutely. The sulfate-free, nutrient-rich formulas are safe for treated hair and help restore softness, shine, and resilience without stripping color.
Q5: Does this set help with hair loss or breakage?
A: While not a medical treatment for hair loss, the duo supports scalp health, pore detox, and nutrient delivery—creating the ideal environment for stronger roots, reduced shedding, and improved hair density over time.
