GROWUS Damage Therapy Shampoo 500ml

Professional salon repair, in your shower every day. The GROWUS Damage Therapy Shampoo is a Korean Thalassothérapie hair care treatment built around the ocean's most restorative ingredients — hydrating and moisturising dry, brittle hair through the synergistic effect of 7-layer collagen and 5 types of protein ingredients, promoting shiny, healthy hair from the roots. Whether your hair has been damaged by colouring, bleaching, heat styling, or simply time, this is the shampoo that visibly repairs it — wash after wash.

GROWUS is a premier Thalassothérapie hair and body care brand dedicated to restoring the body's natural balance through nutrient-rich ingredients derived from the ocean, the source of life. Every formula in the Damage Therapy line reflects that philosophy: real ingredients, real concentrations, real results.

Why it works:

7 types of Collagen (Hydrolyzed Collagen, Collagen Extract + 5 additional collagen forms) — deliver the healing benefits of the sea to damaged hair, leaving it moist and resilient  by replenishing lost protein at every structural layer of the hair shaft

5 types of Protein (Hydrolyzed Keratin, Milk Protein Extract, Hydrolyzed Barley Protein, Hydrolyzed Corn Protein, Hydrolyzed Soy Protein) — a double coating therapy that uses high molecular PPT to form a protective film on the hair surface and low molecular PPT to provide structural support to the hair cortex — filling damage from the inside out

Marine Pearl Complex (Pearl Extract + Himalayan Pink Salt + 7 Collagen types) — a blend that delivers the richness of the sea to damaged hair, leaving it moist and resilient , while the mineral-rich pink salt supplies essential trace elements to strengthen each strand

Salicylic Acid — provides anti-hair loss care  by gently exfoliating the scalp, removing dead skin cells and product buildup that block hair follicles and inhibit healthy growth

Niacinamide — supports a healthy scalp barrier, regulates oil-moisture balance, and soothes irritation, creating the perfect foundation for healthy hair growth 

How to use: Wet hair with warm water, apply a moderate amount of shampoo, and massage for 2–3 minutes. Only 1–2 pumps are needed, thanks to GROWUS's unique foaming technique. Rinse thoroughly with water, ensuring no residue is left behind.  Follow with the GROWUS Damage Therapy Treatment or Conditioner for maximum repair results. Use daily or as needed.

Best for: Individuals struggling with tangles and difficulty brushing or combing, dry and frizzy hair after shampooing, matted hair, a flaky scalp, or experiencing constant hair breakage.  · Color-treated & bleached hair · Heat-damaged hair · All hair types including sensitive scalp · Made in Korea 🇰🇷

Why Seoulma recommends it:

Hair care is one of the most underrated categories in K-Beauty — and GROWUS is one of the brands that is quietly changing that. The Damage Therapy Shampoo is built on the same philosophy that makes K-Beauty skincare so effective: layer the right ingredients at meaningful concentrations, address the root cause of the problem rather than just masking it, and treat the product as a genuine treatment rather than just a cleanser.

What strikes you immediately is the foam. GROWUS's unique foaming technology means just one or two pumps creates a rich, dense lather that completely saturates the hair — which is why the 500ml lasts far longer than you'd expect. Within that foam, the 7-type collagen and 5-type protein complex is doing something most shampoos simply can't: actually filling the gaps in a damaged hair shaft. 

The scalp care angle is also genuinely impressive. The Salicylic Acid, Niacinamide, and Bifida Ferment Lysate combination is a full scalp treatment in its own right — exfoliating buildup, rebalancing the microbiome, and reducing inflammation all in one wash. Healthy scalp equals healthy hair growth, and this formula takes that relationship seriously in a way that most hair care brands simply don't.

We recommend it as the foundation of any serious hair repair routine — and even more so when paired with the GROWUS Damage Therapy Conditioner and No-Wash Treatment for the full professional-grade system. If your hair has been through colour, bleach, or years of heat styling and nothing has made a lasting difference, this is the place to start.
