CP-1 Shampoos
CP-1 shampoos by Esthetic House cover the main reasons Koreans visit a hair salon in one wash: protein repair, scalp purification, moisture retention, and targeted anti-hair-loss care. The 10+ shampoos on skinsli range from the 3 Seconds Hair Fill-Up formula - which uses a rapid peptide complex to fill surface damage in the time it takes to lather and rinse - to the ginger-based Purifying Shampoo, which clears scalp buildup without stripping the lengths. Sizes run from 100ml travel to 500ml daily bottles.

CP-1 Shampoos: How to Choose Between Protein, Ginger, Moisture, and Scalp Formulas
CP-1 by Esthetic House is a Korean professional hair care line built around targeted scalp and strand repair. The shampoo range on skinsli spans five distinct functional families: protein fill-up, ginger scalp purification, daily moisture, scalp anti-hair-loss, and a mint cooling option. Picking the right one means matching your primary hair concern rather than reaching for a general-purpose cleanser.
CP-1 and the Esthetic House system
Esthetic House is a Korean professional brand whose CP-1 sub-line was originally formulated for salon back-bar use. The shampoos contain higher concentrations of active ingredients than typical retail formulas and are designed to work within a layered routine - shampoo followed by a matching CP-1 conditioner or treatment. The name refers to a "complex protein" philosophy: most formulas include at least one keratin or amino-acid component alongside the primary active.
3 Seconds Hair Fill-Up Shampoo: fast peptide repair
The 3 Seconds formula is the most distinctive in the range. It uses a rapid-bind peptide complex that the brand calls a "micro-filler": small protein fragments penetrate surface cuticle gaps while you lather, smoothing the strand before you rinse. The name reflects the claimed action window - the fill-up process is essentially complete within a standard 3-second rub. It does not rebuild internal cortex structure (that requires deeper treatment) but it visibly reduces roughness and frizz from the first wash.
Best suited to hair that is regularly heat-styled or chemically treated.
Ginger Purifying Shampoo: scalp reset
The Ginger Purifying Shampoo uses a ginger root extract base to stimulate circulation and break down scalp sebum and product buildup. It is available in 100ml and 500ml formats on skinsli. The 100ml is positioned as a travel or occasional-use size, while the 500ml is for those who need a regular scalp reset. It is not a daily shampoo for most hair types - the clarifying action can be drying if used every wash on fine or dry hair. Once or twice per week is typical.
Aquaxyl Complex Intense Moisture Shampoo: dehydrated hair
Aquaxyl is a patented humectant complex (xylose + glucose + sodium glucuronate) that helps hair retain water throughout the day rather than just during the wash. The CP-1 Aquaxyl shampoo is primarily for hair that feels dry and brittle even after conditioning - often a sign of chronic dehydration rather than damage. It cleanses gently and pairs well with the matching CP-1 Aquaxyl conditioner for maximised moisture retention.
Anti Hair-Loss Scalp Infusion Shampoo: thinning and shedding concerns
The Scalp Infusion Anti Hair-Loss Shampoo is formulated with ingredients targeted at the scalp environment rather than the strand itself. It includes agents to reduce scalp inflammation and excess sebum, which are both linked to premature hair loss in Korean hair care research. It is available in the 250ml size on skinsli and is typically used as part of a scalp-focused routine alongside a scalp serum or ampoule.
Note that cosmetic anti-hair-loss products address scalp conditions and do not treat androgenetic (hormonal) hair loss, which requires a medical consultation.
Head Spa Cool Mint Shampoo: oily scalp and post-workout
The Head Spa Cool Mint Shampoo is a cooling-sensation formula using menthol and peppermint to reduce scalp heat, a common cause of excess sebum production in humid conditions. It gives a strong cooling effect within 30 seconds of application - more pronounced than most salon mint shampoos. Useful for anyone with an oily scalp or for regular post-exercise washes where a normal shampoo leaves the scalp feeling heavy.
Daily Moisture Natural Shampoo: every-day use
The Daily Moisture Natural Shampoo is the gentlest formula in the range and the only one CP-1 positions as a true daily cleanser for all hair types. It uses a mild sulfate-free base with a basic amino acid moisture complex. For people who need one shampoo that works for frequent use without scalp dryness, this is the starting point before adding a more targeted formula a few times per week.
Sizes and how to pair with CP-1 treatments
Most CP-1 shampoos on skinsli are available in the 500ml size, with the Ginger Purifying also stocked in 100ml and the Scalp Infusion and Magic Styling available in 250ml. The 500ml bottles are value-sized for daily use. CP-1 shampoos are designed to work best when followed by a CP-1 conditioner or the 3 Seconds Hair Filler treatment, which extends the protein repair initiated in the shampoo step.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does '3 Seconds' mean in the CP-1 3 Seconds Hair Fill-Up Shampoo?
The name refers to the speed of the protein fill-up action. The micro-peptide complex in the formula is designed to bind to surface cuticle gaps within approximately 3 seconds of contact - a standard lather time. You do not need an extended leave-in period. Rinse normally and the smoothing effect is retained.
Can I use the CP-1 Ginger Purifying Shampoo every day?
The Ginger Purifying Shampoo is a clarifying formula rather than a daily cleanser. Using it daily on most hair types will over-strip the scalp and lengths. Once or twice per week is the typical cadence, alternating with a gentler daily shampoo. The 100ml size on skinsli is sized for this occasional-use pattern; the 500ml is for people replacing their main shampoo with a more frequent ginger rotation.
Is the CP-1 Bright Complex Intense Nourishing Protein Shampoo suitable for fine hair?
It can be, used once or twice per week. Heavy protein overload can make fine hair feel stiff and brittle over time, so daily use of a concentrated protein shampoo is not recommended for fine strands. For everyday washes, the Daily Moisture Natural Shampoo is a better base; reserve the protein formula for sessions after heat styling or chemical treatments.
When should I choose the Aquaxyl Moisture Shampoo over the protein shampoo?
Choose Aquaxyl when your hair feels dry and limp even after conditioning - a pattern that suggests lack of moisture retention rather than protein loss. Protein shampoos are better for hair that snaps, has rough texture, or has been chemically straightened or permed. If you are unsure, try the Daily Moisture Natural first and assess after two weeks of use before adding a more targeted formula.
How effective is the CP-1 Anti Hair-Loss Scalp Infusion Shampoo for hair loss?
The shampoo targets scalp-environment factors: buildup, inflammation, and excess sebum that can contribute to premature shedding. It is most effective for hair loss caused by scalp conditions or lifestyle factors. It does not treat androgenetic or hormonal hair loss, which is driven by internal causes requiring medical treatment. Results are typically felt as reduced daily shedding over 4-8 weeks when used consistently.
How strong is the cooling sensation in the CP-1 Head Spa Cool Mint Shampoo?
The cooling effect is strong relative to most commercial mint shampoos - comparable to a professional scalp treatment at a salon. The menthol activates within 20-30 seconds of application. Some users with a very sensitive scalp find it intense at first; if so, leaving it on for a shorter time before rinsing reduces the effect. It is not recommended directly before bedtime if you are sensitive to cooling sensations disrupting sleep.
Do I need to use a CP-1 conditioner with these shampoos?
A conditioner is recommended after any of the CP-1 shampoos, but it does not have to be from the CP-1 line. Pairing with a matching CP-1 conditioner (such as the Aquaxyl conditioner after the Aquaxyl shampoo) reinforces the active ingredient system and gives more consistent results. That said, any quality conditioner suited to your hair type will give acceptable results when used after a CP-1 shampoo.
Should I buy the 100ml, 250ml, or 500ml size?
The 100ml Ginger Purifying is a trial or travel size, ideal for occasional scalp resets. The 250ml formats (Scalp Infusion, Magic Styling) are good for once-a-week-use shampoos where a 500ml would take months to finish. The 500ml is the best value for daily-use shampoos like the Aquaxyl, Daily Moisture, or Mint where you will go through the bottle in 2-4 months of regular washing.
Are CP-1 shampoos safe for color-treated hair?
The Daily Moisture Natural and Aquaxyl shampoos are color-safe - they use mild bases that do not strip hair color. The Ginger Purifying is a clarifying shampoo and can accelerate color fade with frequent use; limit it to once a week at most on color-treated hair and use cool water when rinsing. The protein shampoos are color-safe and actually help stabilize chemically treated strands.
Are the CP-1 products on skinsli authentic and sourced from Korea?
Yes. Skinsli sources CP-1 directly from Korean distributors and all products are authentic Esthetic House products manufactured in South Korea. Products arrive in original packaging with Korean labeling and include English sticker translations where applicable.
