TS Shampoos: A Guide to Korea's Scalp-Care Lineup
TS became one of Korea's top-selling scalp-care brands by focusing on hair loss prevention and scalp health rather than cosmetic shine. The brand's shampoos use ingredients like biotin, herbal extracts, and scalp-cooling compounds to address thinning, excess sebum, and an irritated scalp. The collection on skinsli covers 35 shampoos across multiple product lines, from small 300g packs to large 1000ml and 1000g refill-friendly formats. This guide covers the main lines, their ingredients, and how to choose between them.
TS: scalp-first Korean hair care
TS (Taeshin) built its reputation in Korea primarily on the Trust TS Shampoo, which became a bestseller by targeting androgenetic hair thinning in a market where that concern was underserved by mainstream brands. Korean pharmacies and online channels drove initial adoption, and the brand expanded from there into multiple lines targeting different scalp conditions. The focus remains on the scalp rather than the hair shaft - TS shampoos aim to create conditions where hair can grow normally, rather than coating the hair strand to make it appear thicker or shinier.
X Biotin Shampoo 500g: vitamin B7 for hair support
The TS X Biotin Shampoo 500g combines the scalp-care base with added biotin (vitamin B7). Biotin is involved in keratin production, the structural protein of hair. Biotin deficiency is associated with hair thinning and breakage, though deficiency in otherwise healthy people is uncommon. As a topical ingredient in shampoo, its main mechanism is supporting the follicle environment rather than providing the systemic effect that oral biotin supplements target. The X Biotin shampoo is the right choice if you want a scalp-care formula with additional nutritive support, particularly if your hair has become brittle or prone to breakage alongside thinning.
Cool Shampoo 500g: scalp-cooling for oily and irritated scalps
The TS Cool Shampoo 500g uses menthol and cooling agents to address scalp heat and excess sebum. An overheated scalp produces more sebum, which can block follicles and create an environment unfavorable to hair growth. The cooling effect is immediate and noticeable at rinse-out. The formula is a good match for people who exercise regularly, live in warm climates, or find their scalp gets greasy by midday. It is also popular in summer as a replacement for heavier formulas. The cooling sensation is not a surface gimmick - it actively reduces scalp temperature for a period post-wash, which is the mechanism for sebum reduction.
GD Shampoo 813ml: the large-format scalp treatment
The TS GD Shampoo is available in an 813ml size, making it one of the larger single-bottle options in the range. GD formulas in the TS line target sebum control and scalp microbiome balance alongside the standard hair thinning concerns. The larger bottle size is practical for household use or for people who wash their hair daily and go through product quickly. It is formulated for normal to oily scalps. The size also makes the per-wash cost lower than the smaller options, which matters for daily users on a longer term regimen.
Citrus and Glow Shampoo and Black Edition 500g
The Citrus and Glow Shampoo 1000g is the largest pack in the range and carries a citrus-extract profile designed for scalp clarity and a lighter, brighter feel. Citrus extracts contribute mild exfoliating acids that help break down product and sebum buildup on the scalp. The 1000g size is suited for families or for anyone running through shampoo quickly. The Black Edition Shampoo 500g takes a different approach: it is formulated for users concerned with premature graying alongside hair thinning, and uses a darker-pigment botanical base. It is not a pigment-depositing toner - it is a scalp treatment that includes ingredients associated with melanin support.
Beady Shampoo and Erseongcho Set
The Beady Shampoo 500g uses a bead-type formula where micro-capsules release actives during lathering, providing a slightly different sensory and delivery experience compared with standard gel shampoos. The capsules burst on contact with water and friction, releasing their concentrated contents onto the scalp. The Erseongcho Shampoo+Treatment Set combines a shampoo with a conditioning treatment in one purchase - a practical entry point for people who want to address both cleansing and post-wash conditioning in one order. Erseongcho refers to a Korean herbal compound used in traditional medicine for hair-related applications.
Choosing the right size: 300g through 1000ml
TS shampoos are available across a wide size range. The 300g Premium TS is the smallest and suits travel or a trial purchase before committing to a larger pack. The 500g options (Cool, X Biotin, Trust TS, Black Edition, Beady) are the standard home size and last four to eight weeks for daily users depending on hair length. The 813ml GD and 1000ml Premium TS are household or refill-tier sizes that reduce per-wash cost significantly. The 1000g Citrus and Glow is the largest single pack. If you are unsure which line to commit to, start with a 500g format - it is enough to run a six to eight week test of whether the scalp condition is improving before buying a larger refill.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Is there clinical evidence that TS shampoos reduce hair loss?
TS conducted internal consumer studies in Korea showing improved scalp condition and reduced shedding with consistent use. Independent peer-reviewed clinical trials are not widely available in English-language literature for TS specifically. The mechanism - clearing scalp sebum, reducing inflammation, and supporting follicle health - is supported by broader dermatological research on how scalp environment affects hair cycling. Results vary by hair loss type: TS shampoos address sebum-related and inflammation-related thinning most effectively; androgenetic alopecia (genetic pattern baldness) responds more to oral or topical minoxidil and requires a dermatologist's input.
Should I choose the X Biotin Shampoo 500g or the Trust TS Shampoo 500g?
The Trust TS Shampoo focuses on scalp environment - reducing excess sebum and scalp inflammation that can impede healthy hair growth. The X Biotin Shampoo adds biotin (vitamin B7) to that base, targeting the keratin production side of hair health. If your primary issue is scalp oiliness, congestion, or inflammation, Trust TS is the cleaner choice. If your hair is also brittle, breaking easily, or growing slowly alongside any thinning, the X Biotin version adds a nutritive layer to address that simultaneously.
How often should I use the Cool Shampoo 500g if I have an oily scalp?
For an oily scalp, daily use of the TS Cool Shampoo is appropriate - it is formulated to handle frequent washing without stripping. The cooling and sebum-control action is cumulative: daily users typically notice scalp greasiness extending longer between washes after two to four weeks of consistent use. If you have a dry scalp but use the Cool Shampoo for the cooling sensation in warm weather, reduce to three or four times per week to avoid over-drying.
Does the Black Edition Shampoo 500g reverse gray hair?
No. The TS Black Edition Shampoo does not reverse or mask gray hair - it contains no pigment-depositing agents and does not work like a color-depositing shampoo. Its 'Black Edition' positioning refers to a formula that includes ingredients associated with supporting melanin production in the scalp environment, such as black soybean extract or similar botanicals. These may slow premature graying that is related to oxidative stress or nutrient deficiency, but they do not re-pigment hair that has already gone gray. Manage gray-reversal expectations realistically; this is a scalp treatment, not a colorant.
What does the treatment in the Erseongcho Shampoo+Treatment Set do?
The treatment in the Erseongcho set is a conditioning product applied after shampooing. Erseongcho is a Korean herbal compound (a combination of traditional medicinal plants) applied to scalp and hair to condition and add moisture while supporting scalp health. The treatment step re-adds moisture that the shampoo's cleansing action removes, which reduces breakage and improves manageability. Using shampoo and treatment from the same line keeps the ingredient interaction predictable - neither product is designed to work against the other's active ingredients.
What does the TS GD Shampoo 813ml smell like?
The GD Shampoo has a clean, slightly herbal scent profile typical of TS scalp-care formulas - not heavily perfumed. Most TS shampoos use light fragrance rather than the strong floral or fruity scents common in mainstream hair care. The herbal notes come from the plant extracts in the formula. The scent dissipates quickly after drying; it is not designed to linger in the hair as a fragrance product. If fragrance sensitivity is a concern, the minimal scent profile of TS products is generally easier to tolerate than Western supermarket brands.
Do the micro-capsules in the TS Beady Shampoo 500g scratch the scalp?
No. The micro-capsules in the Beady Shampoo are soft and dissolve on contact with water and the friction of massage. They do not function as physical exfoliants in the way that scrub beads do - they burst to release their contents rather than abrading the skin. The sensation is slightly different from a standard gel lather, but it is not scratchy or rough. People with a very sensitive or broken scalp should still patch-test before full use, as with any new shampoo.
Are TS shampoos on skinsli.com imported directly from Korea?
Yes. TS is a Korean brand and all shampoos in this collection are imported directly from Korea. The packaging carries Korean-language text and is the same product sold domestically in Korea. Skinsli does not carry reformulated or licensed versions of TS products. Korean-language labeling on the bottle confirms the origin.
Is the Citrus and Glow Shampoo 1000g good for removing scalp buildup from styling products?
Yes. The Citrus and Glow Shampoo's citrus extract base includes mild organic acids that help break down product residue and sebum buildup better than most standard shampoos. If you use dry shampoo, styling sprays, or volumizing powders regularly, the citrus formula is more effective at clearing that buildup than a plain scalp treatment shampoo. Use it as your primary wash on days after heavy styling product use. For routine maintenance washing without styling products, any TS shampoo works; the citrus formula is not required for non-buildup days.
