Ryo Nutrition

In Korean hair care, nutrition refers to delivering proteins, amino acids, vitamins, and lipids that the hair strand or scalp follicle requires but has been depleted of. For damaged hair, nutrition means protein repair - rebuilding the keratin structure in bleached or over-processed strands. For thinning hair, nutrition means follicle-support through micronutrient delivery - ginseng extracts, yeast derivatives, and botanical complexes that support the scalp environment where hair grows.

RYO separates these two types of nutrition into distinct product lines rather than using a single formula for both, which is a more targeted approach than most single-formula nutrition products.

The Extreme Damage Nutrition shampoo (480ml), conditioner (480ml), and treatment (300ml) form a complete three-step routine for severely damaged hair. The shampoo uses a gentle surfactant base that cleans without further stripping - standard high-lather shampoos continue to damage already-compromised cuticles with every wash. The conditioner seals the strand immediately after the shampoo strips the surface, preventing moisture loss between washes. The treatment provides the intensive weekly protein dose that the conditioner cannot deliver in a rinse-off timeframe.

Use the shampoo daily, the conditioner every wash, and the treatment once or twice per week. Do not skip the conditioner even on treatment days - the conditioner step maintains smoothness between treatment sessions.

The Hambit sub-line extends the Extreme Damage Nutrition formula with a broader Nutrition Care designation. The Hambit Extreme Damage and Nutrition Care Conditioner (592ml) is the largest conditioner in the range, sized for thick or long hair where conditioner volume matters. The Hambit Treatment (300ml) uses the same balanced protein-plus-moisture approach described in the treatment guide.

The Hambit variants are a slightly richer formula than the core Extreme Damage Nutrition products - appropriate for hair that is moderately damaged from heat and color but has not been bleached to severe porosity. The extra volume in the Hambit Conditioner makes it the economical choice for regular long-hair users.

The Hair Nutrition Shine Conditioner at 400ml is the everyday maintenance conditioner in the nutrition line - not focused on extreme repair, but on delivering daily nutrition that improves shine and smoothness on normal to moderately dry hair. It does not carry the Extreme Damage or Hambit designation, which means it is calibrated for hair that is mildly dehydrated or dull rather than structurally compromised.

Use it as your daily conditioner when the Extreme Damage formula is too heavy for your hair type but you still want a nutrition-forward conditioner over a basic detangler. At 400ml it lasts 3-4 months of daily use on medium-length hair.

The Red Ginseng Nutrition Shampoo at 820ml is the high-volume premium shampoo in the nutrition range. Red ginseng provides the same potent scalp-stimulating ginsenoside complex as the Red Diagnosis treatment line, but in a daily-wash shampoo format. The Nutrition designation means the formula also adds hair-shaft conditioning alongside the scalp-active complex.

At 820ml this is the most economical format for daily use - the large bottle gives approximately 4-6 months of daily washing at standard amounts for medium-length hair. It suits people who want both scalp support and strand nutrition in a single daily wash step without running a multi-product routine.

The Beer Yeast Hair Root Nutrition Talmomampu is a scalp-application ampoule product. Talmomampu (탈모앰플) refers to a leave-on scalp treatment specifically formulated for hair-loss symptom care. Beer yeast (saccharomyces cerevisiae extract) is rich in B vitamins (particularly biotin, niacin, and B5), minerals, and amino acids that support follicle metabolism and hair shaft protein production.

Apply to the scalp after washing, working into the roots without rinsing. At 600ml this is a generous size for a leave-on scalp treatment - it provides 4-6 months of daily use at 5-10ml per session. Beer yeast ampoules are used consistently over an 8-12 week period to see measurable changes in shedding frequency and strand thickness.

For bleached or heavily processed hair, the most effective RYO nutrition routine stacks three products: the Extreme Damage Nutrition Shampoo (daily cleanse with gentle surfactants), the Hambit Extreme Damage Conditioner (daily conditioning after each wash), and the Extreme Damage Nutrition Treatment or Hambit Treatment (once or twice per week intensive protein session). Between-wash care includes applying a leave-on product if the hair is extremely porous.

For hair that is thinning alongside damage, add the Beer Yeast Talmomampu to the scalp daily after the shampoo and conditioner step. The Beer Yeast addresses the scalp/follicle side while the Extreme Damage products address the strand side - two different problems requiring two different approaches.

Protein overload is a real risk when using multiple protein-rich products in the same routine. Signs include stiff, brittle hair that snaps rather than stretching, and tangles that were not present before adding protein. To prevent this, alternate protein days with moisture days: use the Extreme Damage Nutrition Treatment on Tuesday and Saturday, and use a moisture-focused treatment (such as a non-protein conditioner) on the other wash days. The Hair Nutrition Shine Conditioner is lower in protein than the Extreme Damage Conditioner and can serve as the moisture-focused alternative in the rotation.

If protein overload has already occurred, stop protein products entirely for 1-2 weeks, use only moisturizing shampoo and conditioner, and reintroduce protein gradually at once-per-week frequency.
