RYO Shampoos
RYO shampoos span 70+ SKUs across multiple product lines, from sensitive and mild daily washes to targeted scalp treatments and strengthening formulas. Key variants include the Red Ginseng Nutrition Shampoo (820ml economy size), Obella Shampoo Herb Citron (600ml), Lutzen Women's Custom Shampoo (available in 242ml and 515ml), and Deep Cleansing Cooling Shampoo (480ml). Most bottles range from 400ml to 820ml, covering everyday and large-family use. Each line targets a specific scalp or hair concern, so the right pick depends on whether you are addressing sensitivity, root strength, nutrition, or cooling cleanse.

RYO Shampoos: Which Formula Fits Your Scalp and Hair?
RYO offers 70+ shampoos on skinsli, covering concerns from sensitive scalp to thinning hair to oily root cleanse. The brand structures its shampoos by scalp condition rather than hair texture - so the first question to ask is not hair type (straight, wavy, curly) but scalp state (oily, dry, irritated, thinning). This guide maps the major RYO shampoo lines to their intended use, covers size and format differences, and outlines how to layer a second step from the same range.
Sensitive and Mild Line: Daily Use Without Irritation
The RYO Sensitive Mild Shampoo (480ml) is listed in two near-identical SKUs - Sensitive Mild Shampoo and Sensitive and Mild Shampoo - both targeting scalp sensitivity and daily cleanse. These are lower-foam, lower-irritation formulas intended for people who shampoo every day or who have a reactive scalp. They are not medicated; rather, they minimize common sensitizing ingredients found in standard shampoos. The 480ml size suits about two months of daily use for medium-length hair. If you experience scalp tightness or redness after shampooing, the Sensitive line is the appropriate entry point in the RYO range.
Hair Root Strengthening Shampoo: Targeting Thinning at the Root
The Hair Root Strengthening Shampoo (480ml) is formulated for a scalp prone to hair fall or weak roots. Korean haircare brands typically use plant-derived extracts - including various ginseng, fermented ingredients, or algae - to address root fragility. This shampoo works best as a daily cleanser rather than an occasional treatment; consistent use over four to eight weeks gives a better baseline for evaluating its effect on shedding. It should not replace a dermatologist consultation if hair loss is rapid or patterned.
Red Ginseng Nutrition Shampoo: Large-Format Nourishment
The Red Ginseng Nutrition Shampoo comes in an 820ml format - the largest single bottle in this collection - making it a good choice for households that go through shampoo quickly or prefer fewer repurchases. RYO's red ginseng formulas use fermented or extracted red ginseng as a scalp-nourishing active, a well-established ingredient in Korean haircare for its circulation-supporting and antioxidant properties. The larger bottle reduces cost per wash significantly compared to 400-480ml bottles.
Deep Cleansing Cooling Shampoo: Removing Buildup and Sebum
The Deep Cleansing Cooling Shampoo (480ml) combines a higher-cleansing surfactant blend with a cooling agent, providing both thorough scalp cleanse and a physical refreshing sensation. It suits oily scalp types or people who use styling products that leave residue. The cooling effect comes from menthol or camphor-adjacent ingredients - the sensation is immediate on application and lasts through the rinse. This is not a daily formula for dry or sensitive scalps; it is best used two to three times per week as a deeper cleanse, alternating with a milder shampoo on other days.
Obella Shampoo Herb Citron: Herbal and Citrus Formula
The Obella Shampoo Herb Citron (600ml) is among the larger standard-size bottles in this collection. Citron (yuja) is a common Korean haircare ingredient known for its clarifying and scalp-brightening properties, and herb citron formulas typically include a blend of botanical extracts. The 600ml size is a practical middle ground between the 480ml standard and the 820ml economy Red Ginseng bottle. Obella is a sub-line of RYO, so the formulas align with the same scalp-first approach but with a botanical-herb scent profile.
Lutzen Women's Custom Shampoo: Sizes and Personalization
The Lutzen Women's Custom Shampoo is available in two sizes in this collection: 242ml and 515ml. The 242ml is a home or travel-mid size - compact enough to test the formula before committing to a larger bottle. The 515ml is the full-size version for sustained use. Lutzen is RYO's scalp-precision sub-line, and the Women's Custom formula is tailored to typical female scalp concerns (hormonal sebum variation, stress-related shedding). It sits at a mid-price point in the RYO range - above the Sensitive line, below the premium Luxury HBX products.
Hair Nourishing Shine Shampoo: For Hair Texture and Gloss
The Hair Nourishing Shine Shampoo (400ml) addresses hair texture and surface gloss rather than scalp-specific concerns. It is the most hair-length-focused formula in this collection, making it a better fit for people whose scalp is healthy but whose hair mid-lengths and ends are dry or lacking shine. At 400ml it is the smallest bottle in the current RYO shampoo range on skinsli, suitable as a secondary or alternating shampoo. It can be rotated with a scalp-targeted formula - use Nourishing Shine on wash days focused on hair condition, and a scalp shampoo on cleanse-focused days.
FAQ

FAQ
Frequently asked questions
How many RYO shampoos are available on skinsli?
There are 70+ RYO shampoos in this collection. They span sensitive and mild formulas, scalp-strengthening shampoos, the Red Ginseng Nutrition line, Deep Cleansing Cooling, Obella Herb Citron, Lutzen Women's Custom, and Super Room Premium, across bottle sizes from 242ml to 820ml.
Which RYO shampoo works for daily washing on a sensitive scalp?
The Sensitive and Mild Shampoo (480ml) is formulated for daily use on a reactive or sensitive scalp. It uses a lower-irritation formula without the high-foam cleansing agents common in standard shampoos. It is one of the gentler options in the RYO range and suits people who shampoo every day or every other day.
Is the 820ml Red Ginseng Nutrition Shampoo significantly cheaper per wash than the 480ml bottles?
Yes. The 820ml bottle holds roughly 70% more product than the 480ml standard bottles at a proportionally lower cost per milliliter. For households with two or more people washing frequently, the 820ml format reduces how often you reorder and lowers the cost per wash compared to repeatedly buying smaller bottles.
Is the Deep Cleansing Cooling Shampoo suitable for an oily scalp every day?
It can be used daily if your scalp is consistently oily, but most users with moderately oily scalps find two to three times per week is sufficient. Daily use of a strong-cleansing formula on a scalp that only leans oily can strip too much sebum and trigger rebound oiliness. Alternating with a milder formula on lighter-cleanse days is a common approach.
Should I buy the Lutzen Women's Custom Shampoo in the 242ml or the 515ml?
The 242ml is a reasonable size to test whether the formula suits your scalp before committing to the 515ml. If you already know the Lutzen Women's Custom works for you, the 515ml lasts about twice as long and costs less per wash. The 242ml is also practical if you want to use it as a second shampoo alongside a different formula.
Does the Hair Root Strengthening Shampoo actually reduce hair shedding?
RYO's Hair Root Strengthening Shampoo is a cosmetic product designed to support scalp condition and reduce shedding linked to a weakened scalp or hair roots. Results vary by individual and scalp condition. Users typically report changes after consistent daily use over four to eight weeks. It is not a treatment for alopecia or hormonal hair loss - for rapid or patterned hair loss, consult a dermatologist.
What does the Obella Herb Citron Shampoo smell like?
The Obella Herb Citron Shampoo has a botanical-herbal scent with a citrus top note from the yuja (citron) ingredient. It is fresher than the earthy or herbal scent profiles of ginseng-based RYO shampoos. The fragrance fades after rinsing and does not typically linger on the hair after drying.
Can I use a RYO shampoo alongside a RYO scalp hair pack from the same collection?
Yes. The shampoo and pack serve different steps: shampoo cleanses the scalp, and the weekly pack provides a concentrated nourishment treatment. Use the shampoo first, then apply the pack to the damp scalp and hair lengths, leave 5-10 minutes, and rinse. Keeping both in the same brand family means the formula philosophies (scalp-first, herbal actives) are aligned.
Are RYO shampoos on skinsli the same formula as in Korean stores?
Yes. Skinsli sources directly from Korean B2B suppliers, so the RYO shampoos here are the same Korean-market formulas and packaging sold in Korean pharmacies and beauty retailers. Labels are in Korean; skinsli listings include translated product names and descriptions.
