EVAS Shasha Argan Oil Hair Care: Complete Product Guide
EVAS Shasha is a Korean hair care line that built its identity around professional-grade sizes and argan oil as the primary restorative ingredient. The brand leans into the practical side of hair care: large-format products that last three to four times longer than standard retail sizes, formulas that work with argan oil's natural affinity for hair's lipid mantle, and a product lineup that covers every step from cleansing to styling. This guide covers each product in the range and explains how to build an argan oil routine that addresses dryness, breakage, and manageability.
What argan oil does for hair and why it's in a shampoo
Argan oil (Argania spinosa kernel oil) is cold-pressed from the kernels of the argan tree native to Morocco. Its primary fatty acid composition is roughly 43% oleic acid (omega-9) and 36% linoleic acid (omega-6), alongside a higher-than-average vitamin E (tocopherol) content for a plant oil. In hair care applications, these fatty acids penetrate the hair shaft's cortex more readily than heavier oils like coconut, reducing hygral fatigue (the swelling and contracting cycle that weakens the cortex) and providing a supplementary lipid layer to hair that has been stripped by washing, heat, or chemical treatment.
Including argan oil in a shampoo means the cleansing step deposits a trace of lipid back onto the hair rather than leaving the shaft entirely stripped. The amount is small - the surfactants in the shampoo rinse most product away - but the formulation softens the net harshness of the wash compared to a standard sulfate shampoo without argan oil. The conditioning and treatment products in the Shasha line build on this base with higher concentrations.
Shasha Argan Oil Shampoo and Conditioner (1500 ml)
The Shasha Shampoo and Conditioner are the foundation of the line and are available in both 1500 ml individual bottles and a two-bottle set. The 1500 ml format is a professional or salon-grade volume - at a typical household usage rate of 15 to 20 ml per wash, a 1500 ml bottle lasts 75 to 100 washes for a single user, or roughly 4 to 6 months of daily use. For households with two users, it still covers 6 to 8 weeks each.
The shampoo is formulated for damaged or dry hair - the argan oil addition moderates the surfactant harshness common in high-lather shampoos. It builds a full lather despite the oil content, which is achieved through the balance of surfactant types in the formula rather than through a sulfate-heavy base.
The conditioner is a leave-on-for-2-minutes rinse-out formula that follows the shampoo. Its function is to restore slip and softness after the wash strips protective oils, and to deposit conditioning agents that coat the cuticle and reduce friction between strands - the practical measurement of which is tangles and breakage during combing after washing.
Shasha Argan Erseongcho LPP Hair Pack (1500 ml)
The LPP (Liquid Protein Polymer) Hair Pack is a deep conditioning treatment in the 1500 ml format. LPP technology in Korean hair care refers to hydrolyzed protein chains (typically keratin or silk) broken into small enough molecular fragments to penetrate the hair cortex rather than sitting on the surface. When these fragments enter the cortex, they temporarily fill structural voids left by chemical processing, heat damage, or mechanical stress - the practical result is reduced breakage and improved elasticity.
The Erseongcho component refers to a Korean herbal ingredient (sometimes translated as waterplantain rhizome extract) used in traditional hair care for scalp conditioning. In the context of this product it adds a botanical support layer to the protein-focused LPP treatment.
Usage protocol: apply after shampoo to towel-dried hair, focusing on mid-lengths and ends where damage typically accumulates. Leave on for 5 to 10 minutes under a shower cap if possible - the heat from the scalp improves penetration. Rinse thoroughly. Use once or twice weekly as a replacement for your regular conditioner on treatment days.
Shasha Argan Oil Hair Serum (200 ml)
The Hair Serum is a leave-in silicone-argan oil blend applied to towel-dried hair before styling. Its primary functions are heat protection, frizz control, and surface shine. The silicone component in most hair serums forms a flexible film over the cuticle that reflects light (producing shine) and reduces moisture absorption from humid air (reducing frizz).
Application: dispense 1 to 3 pumps depending on hair length and thickness, emulsify between palms, and apply from mid-lengths to ends. Avoid the scalp, where excess silicone can build up over time and require a clarifying shampoo to remove. For heat styling, the serum provides meaningful protection at temperatures up to 180°C; for tools above that temperature, a dedicated heat protectant with a higher thermal threshold should be used in addition.
The serum is also effective as an anti-frizz finisher on dry hair - a small amount (half a pump) smoothed over the hair surface controls flyaways without weighing the style down.
Shasha Argan Oil Hair Spray (250 ml)
The Hair Spray is a finishing spray for hold and frizz control. Korean hair sprays in this category typically use lighter polymers than Western maximum-hold sprays, producing a flexible hold rather than a stiff helmet effect. The argan oil addition reduces dryness that many hair sprays leave behind - the vitamin E in argan oil acts as a conditioning buffer against the drying alcohol commonly used as a propellant carrier.
Use it as a finishing step after styling is complete. For longer hold, layer with a light-hold cream or mousse before blow-drying and finish with the spray after styling. For a natural look, mist from 30 cm away rather than close-range application, which concentrates the hold polymers unevenly.
Shasha Argan Oil Wave Volume Essence (250 ml)
The Wave Volume Essence is a styling product formulated for wavy or perm-set hair that needs definition and bounce support. Volume essences in Korean hair care typically combine lightweight hold polymers with moisturizing agents to keep curl or wave formation without drying the hair structure. The argan oil component maintains flexibility in the curl so it doesn't become crunchy through the wear day.
Application: apply to damp or slightly damp hair after washing, distributing through the length and scrunching upward to encourage curl formation. Diffuse or air dry. The essence can be refreshed on day-two or day-three hair by applying a small amount to the palms with a few drops of water and scrunching over the dry style to reactivate the wave without rewashing.
Body Wash and Body Lotion (1.5 L formats)
The Shasha range extends to body care with the Argan Oil Body Wash and Body Lotion in 1.5 L sizes, plus the Milk and Honey Juisi Grapefruit Body Wash in the same format. The Argan Oil Body Wash is formulated with the same oil-inclusive approach as the shampoo - surfactants balanced with argan oil to clean without stripping the skin's lipid barrier.
The Argan Oil Body Lotion follows with intensive moisture for post-wash skin. A 1.5 L lotion is essentially a 3 to 5 month supply for a single user at a standard pump-per-use rate, making it a strong value for a daily moisturizing routine.
The Grapefruit Body Wash offers a fresh citrus alternative in the same large-format size. It uses a Milk and Honey base for conditioning alongside the grapefruit fragrance and extract. This variant is lighter on the conditioning side than the argan oil version, making it a better fit for people who prefer a squeaky-clean feel after washing rather than a heavily conditioned skin surface.
Building a complete Shasha routine for damaged or dry hair
A full EVAS Shasha argan oil routine for damaged hair works in this sequence:
- Cleanse: Shasha Argan Oil Shampoo - work through roots and scalp, let foam reach mid-lengths without aggressive scrubbing
- Treat (twice weekly): Shasha LPP Hair Pack - towel-dry after shampoo, apply pack to mid-lengths and ends, 5 to 10 minutes, rinse
- Condition (daily or on non-pack days): Shasha Argan Oil Conditioner - 2 minutes, rinse
- Leave-in: Shasha Argan Oil Hair Serum - applied to towel-dried mid-lengths and ends before styling
- Finish: Shasha Argan Oil Hair Spray - after styling is set
The professional 1500 ml sizes mean that even a twice-weekly treatment protocol uses the same bottle for several months before needing replacement. This makes the larger format particularly cost-efficient for intensive repair programs.
Why professional sizing matters: cost per wash comparison
The standard retail size for premium hair care shampoo is 250 to 300 ml. A 1500 ml Shasha shampoo contains roughly five to six standard-size equivalents in one bottle. At a purchase price below the combined cost of five premium small bottles, the value per wash is significantly better - and the convenience of fewer restocks adds a practical benefit beyond pure economics.
For households with more than one user or for anyone maintaining a consistent intensive hair care routine, the large-format Shasha products make more sense than smaller alternatives at a similar price tier. The shampoo and conditioner set bundles two 1500 ml bottles for a further reduction in per-wash cost.

FAQ
Frequently asked questions
What is EVAS Shasha and what makes it different from regular retail hair care?
EVAS Shasha is a Korean professional hair care line built around argan oil in large-format sizes (1500 ml shampoo, conditioner, and hair pack; 1.5 L body wash and lotion). The size difference is the defining practical distinction - a 1500 ml bottle contains five to six standard retail-size equivalents, making cost per wash significantly lower. The argan oil formulation targets damaged, dry, or processed hair with oleic and linoleic fatty acids that supplement the hair shaft's lipid layer.
Does argan oil actually help with damaged or frizzy hair?
Yes, with nuance. Argan oil's fatty acids (primarily oleic and linoleic) penetrate the hair cortex more readily than heavier oils, reducing hygral fatigue - the cycle of swelling and contracting that weakens the cortex over time. The vitamin E content also provides antioxidant protection against environmental damage. For frizz, the oil creates a lipid film over the cuticle that reduces humidity-triggered swelling. The effect is most pronounced with the leave-in serum; in a rinse-out shampoo or conditioner, the deposit is smaller but still softens the harshness of the wash.
How often should I use the Shasha LPP Hair Pack?
Once or twice a week is the standard protocol for a deep conditioning hair pack. On treatment days, use it in place of your regular conditioner after shampooing. Leave it on for 5 to 10 minutes - covering with a shower cap traps heat that improves penetration. On non-pack days, the Shasha Conditioner provides daily conditioning without the protein intensity of the LPP treatment. Over-using protein treatments can make hair feel stiff or brittle, so twice weekly is the practical upper limit for most hair types.
How much Shasha Argan Oil Hair Serum should I use and where does it go?
1 to 2 pumps for short to medium hair; 2 to 3 pumps for long or thick hair. Emulsify between your palms and apply to towel-dried hair from mid-lengths to ends, avoiding the scalp. Applying serum to the scalp area causes silicone buildup that makes hair look limp over time. The serum can also be used on dry hair in a smaller amount (half a pump) to tame flyaways and add surface shine without reapplying to wet hair.
How do the Argan Oil Body Wash and the Milk and Honey Grapefruit Body Wash differ?
The Argan Oil Body Wash is heavier on the conditioning side - it is designed for dry skin that benefits from an oil-inclusive cleanse. The Milk and Honey Grapefruit variant uses a milk and honey base for some conditioning but has a lighter overall feel and a fresh citrus scent. If your skin feels tight after washing and you prefer a more hydrating result, the Argan Oil version fits better. If you prefer a clean, light feel with a brighter fragrance, the Grapefruit version suits you better.
Is the 1500 ml size practical for home use or is it only for salons?
Fully practical for home use. At 15 to 20 ml per wash, a 1500 ml shampoo lasts a single user roughly 75 to 100 washes - about 4 to 6 months of daily washing. For a two-person household it covers 6 to 8 weeks each. The bottle format is the standard pump-top design and stores in a shower corner or bath caddy without any special handling. Professional-grade sizing simply means better cost per wash, not salon-only use.
Is the Wave Volume Essence only for permed hair or does it work for natural waves?
It works for both. The formula supports wave and curl definition regardless of whether the wave is natural or chemically set. For natural waves and 2b to 3a curl patterns, apply to damp hair and scrunch upward to encourage formation before air drying or diffusing. For permed hair, it helps maintain the wave shape between washes and reduces the drying effect that alcohol-based styling products can have on chemically treated hair.
What level of hold does the Shasha Argan Oil Hair Spray provide?
Light to medium hold with a flexible finish rather than a stiff or crunchy result. This is typical of Korean finishing sprays which prioritize natural movement over maximum hold. The argan oil in the formula reduces the dry or brittle feeling that high-alcohol sprays sometimes leave. For styles that need strong hold throughout the day, layering a light mousse or cream before blow-drying and finishing with the spray gives more reliable longevity.
Are Shasha Argan Oil products suitable for color-treated or chemically processed hair?
Yes - the argan oil formulation is well-suited to processed hair, which typically has elevated porosity and reduced natural lipid content from the chemical treatment. The shampoo's balanced surfactant system is gentler on color than high-sulfate formulas, and the LPP Hair Pack's protein component temporarily fills structural damage in the cortex that chemical processing creates. The hair serum's protective film also reduces color fade from heat styling.

Yes. EVAS Shasha products on skinsli come through Korean wholesale channels. Products arrive with original Korean-language packaging including full ingredient lists in compliance with Korean cosmetics regulations. The brand is Korean and the manufacturing and distribution are based in Korea.
