Jsoop Keratin

Silk keratin formulas combine two protein sources. Silk amino acids are small enough to penetrate the hair cuticle and coat the internal fiber, reducing friction between strands, adding smoothness, and increasing reflectivity (shine). Keratin proteins - larger molecules that form the main structural component of hair - are used to reinforce the outer cuticle layer and fill surface damage on the hair shaft. Together, the silk-keratin complex targets both the internal smoothness and the external protective layer of damaged hair.

This approach is particularly relevant for hair that has been chemically treated (coloring, bleaching, perming, relaxing), heat-damaged from repeated styling, or naturally fine and prone to breakage. Results from a silk keratin regimen build over several weeks of consistent use - single-session improvement in smoothness and shine is noticeable; deeper structural repair requires ongoing application.

The JSOOP Silk Keratin Shampoo appears in multiple formats: 200g and 1000g (standard formulas measured in grams as a denser gel-type product) and 2X in 500ml and 1000ml. The 2X designation indicates a concentrated formula - double the active protein content per application compared to the standard version. This means less product is needed per wash to achieve the same effect, effectively making the 2X bottles more economical per use despite the same or similar price.

For highly damaged or protein-depleted hair, the 2X shampoo is the more efficient choice. For normal or mildly processed hair where keratin support is a maintenance rather than emergency measure, the standard shampoo (200g or 1000g) is sufficient. The 1000g standard and 1000ml 2X are the household economy sizes; the 200g standard and 500ml 2X are the smaller entry-point options.

The Silk Keratin Foam Treatment (200ml) is the most format-distinctive product in the JSOOP Silk Keratin range. A foam treatment is a leave-on or rinse-off conditioning product dispensed as a foam mousse rather than a traditional cream or gel. Foam format allows for even distribution through the hair without over-saturating any one section - it spreads quickly and is particularly practical for fine hair that weighs down under heavy cream treatments.

Apply to damp hair after shampooing, distribute evenly through mid-lengths to ends, leave for 3-5 minutes, then rinse. The foam texture disappears on contact with wet hair, making it feel lighter than cream treatments while still delivering the silk keratin complex. At 200ml foam, the actual product volume is compressed and may last slightly longer than a 200ml cream treatment of the same weight.

The Silk Keratin Protein Hair Essence (150ml) is a leave-in hair care product applied to damp hair after washing. Hair essences in Korean hair care are concentrated treatment serums - a step up from a standard serum in active content, typically applied when hair needs intensive repair rather than maintenance conditioning. The protein essence delivers the silk keratin complex directly without rinsing, allowing longer contact time for protein absorption into damaged areas.

Apply a small amount (about the size of a coin) to towel-dried damp hair, focusing on the mid-lengths and ends. Comb through and style as usual without rinsing. At 150ml and the small amount used per application, the essence lasts approximately 2-3 months at once-daily use. It is the most concentrated single-use protein treatment in the Silk Keratin range and the right step for hair that needs intensive repair between wash sessions.

The Silk Keratin Water Pack 2X (200ml and 200g) is a concentrated hair treatment mask - one step above a standard treatment in protein delivery. 'Water Pack' in Korean hair care refers to a highly hydrating and protein-rich mask that penetrates deeply into the hair cortex for intensive repair. The 2X concentration in the Water Pack matches the elevated formula approach in the 2X shampoo.

Apply to clean, damp hair after shampooing (without regular conditioner), leave for 10-20 minutes (or under heat for faster penetration), then rinse thoroughly. The Water Pack is used once or twice per week as a targeted intensive treatment, not as a daily rinse-out conditioner. It is the highest-intensity treatment step in the Silk Keratin range and best suited for hair that is visibly damaged, brittle, or has lost elasticity from chemical processes.

The JSOOP Silk Keratin Pitch Edition includes the Silk Keratin Treatment Pitch Edition (1000ml) and the Silk Keratin Pitch Edition Gift Set. 'Pitch' in JSOOP's product naming suggests a richer, more viscous formula - a 'pitch' treatment has a denser texture and a higher conditioning ingredient load compared to the standard treatment. The Pitch Edition is positioned as the premium tier within the Silk Keratin treatment range.

The Gift Set bundles the Pitch Edition treatment with other Silk Keratin products for a curated gift or a complete routine trial set. It is the most gift-appropriate format in the Silk Keratin range and one of the few gift sets in the JSOOP collection. For committed Silk Keratin users who want the most intensive conditioning treatment in the range, the Pitch Edition 1000ml is the direct upgrade from the standard Silk Keratin treatment.

A basic Silk Keratin maintenance routine uses: Silk Keratin Shampoo (standard or 2X, depending on damage level) + Silk Keratin Foam Treatment or standard treatment as the rinse-out conditioning step + Silk Keratin Protein Hair Essence (leave-in, daily). This covers wash days with protein conditioning and provides ongoing protein delivery between wash sessions through the essence.

For damaged hair requiring intensive repair: replace the foam treatment with the Water Pack 2X (applied once or twice per week as a deep treatment, left on 10-20 minutes before rinsing) + add the Protein Hair Essence daily. Reserve the Pitch Edition Treatment for weekly conditioning sessions when maximum richness is needed. The 2X shampoo versions are the right choice for damaged hair in either routine - the higher active concentration per wash accelerates the repair timeline.

Some JSOOP Silk Keratin products list their size in grams (200g, 1000g) rather than milliliters. This typically indicates a denser, gel-type formula rather than a liquid - gel shampoos are often measured by weight because the viscosity makes volume measurement less precise. The practical difference for the buyer is minimal: 200g of shampoo gel corresponds approximately to 200ml for most gel formulas. The 1000g Silk Keratin Shampoo is the household economy size equivalent of 1000ml, and the 200g is the smaller entry size.

When comparing the standard gram-format shampoo with the 2X ml-format shampoo, both sizes are comparable in quantity; the 2X version simply delivers double the protein concentration per application. If the product lists grams, assume close equivalence to milliliters for practical purchasing purposes.
