Buying Guide: ILJIN COSMETICS Professional Hair Care
ILJIN COSMETICS covers 65+ SKUs across chemical treatments, hair color, conditioning, and styling products. The range spans the full salon workflow from perm/straightening chemicals to post-treatment LPP repair, through to finishing sprays and waxes. This guide maps the product categories, explains LPP treatment, the perm and straightening chemical options, and the hair dye and styling range.
ILJIN COSMETICS: Professional Salon Supply
ILJIN COSMETICS is a Korean professional hair care brand serving salon professionals and informed home users. The range covers the chemical service workflow - from pre-treatment to post-chemical repair - alongside hair color and styling. At 65+ SKUs, it is one of the more comprehensive professional hair brands on skinsli. Products are labeled and dosed for professional use, meaning some require familiarity with chemical application to use correctly. The Iljin brand name appears in most product titles indicating the brand's own product line rather than a sub-brand distinction.
Iljin LPP Treatment 1000ml: Post-Chemical Repair
The Iljin LPP Treatment 1000ml is a high-capacity protein treatment used for hair repair and strengthening, particularly after chemical processes like perming, coloring, or straightening. LPP stands for Lipid, Protein, and Polysaccharide - the three bond types in the hair structure that chemical treatments disrupt. The 1000ml size is a professional salon format providing many treatment applications per bottle. LPP treatments are applied either in-salon between chemical steps or as a standalone conditioning treatment for severely damaged hair. At this volume, the cost per application is significantly lower than small-size retail protein treatments.
LPP Treatment Hair Pack: Aroma and Chitocyanin Variants
The Iljin LPP Treatment Hair Pack comes in two formula variants: Aroma and Chitocyanin. The Aroma variant is a scented formula for general conditioning use. Chitocyanin is the more specialized version: chitosan (from crustacean shells) combined with cyanin (a plant pigment antioxidant) creates a formula that seals the hair surface while providing antioxidant protection. The Chitocyanin variant is suited for color-treated hair where oxidation protection is valuable alongside the LPP structural repair. Both are leave-in or short-contact treatments used as a mask after shampooing.
Chemical Services: Arene Acid, Cysteine Wave, Volume Magic Straight
Three chemical treatment products cover wave and straightening services. Arene Acid is an acidic permanent wave solution - acid waves are gentler on the hair than alkaline perms and produce softer, looser wave patterns, making them suitable for fine or color-treated hair. Cysteine Wave uses cysteine (an amino acid) rather than ammonium thioglycolate, reducing the chemical damage typical of traditional perms while still creating a curl pattern. Volume Magic Straight is a chemical straightening product, reducing curl and increasing body without fully flattening the hair the way a Japanese straightening treatment does. These products are intended for trained professional application.
Cream Color Hair Dye: Shade 05DB Natural Black Brown
The ILJIN Cream Color Hair Dye in shade 05DB Natural Black Brown is a professional permanent cream dye requiring a developer (oxidant) for activation. 05DB is a shade code: 05 indicates the depth level (medium dark), DB is the base tone direction (dark brown). This shade sits between black and brown, suitable for covering grey on naturally dark brown or dark hair. Professional cream color is mixed with developer at a ratio specified by the brand, applied with a brush, processed for 30-45 minutes, then rinsed. The ILJIN range is a salon-supply dye, meaning it is intended for consistent professional results when used with the correct developer concentration.
Mist Wax 150ml: Flexible Finish
The ILJIN Mist Wax 150ml is a hybrid styling product combining the flexible hold of a wax with a spray delivery format. Mist wax is applied to dry or damp hair for light-to-medium hold, texture definition, and shine without the stiff or crunchy finish of traditional sprays. At 150ml in spray format it is easy to distribute evenly without heavy hand-contact. It suits both natural-texture definition for wave or curl patterns and smooth finish work for straight styles. The mist format dries faster than a cream wax and does not weigh down fine hair.
Finisher Hairspray 400ml: Setting and Hold
The ILJIN Finisher Hairspray 400ml is a professional-size finishing spray for setting completed styles with medium-to-firm hold. At 400ml it is significantly larger than retail finishing sprays and is designed for salon throughput or home users who go through spray product quickly. Finisher sprays are applied as a final step after styling to lock the shape and reduce frizz from humidity exposure. The Finisher label indicates a post-styling setting function rather than a thermal protection spray used before heat tools.
A. J. Krimkala: Specialty Treatment
The ILJIN A. J. Krimkala is listed as a specialty treatment product in the range. Krimkala in the Korean professional hair market typically refers to a keratin or bond-repair treatment used after chemical services or as a standalone hair strengthening step. The A. J. designation differentiates it as a specific formula variant within the ILJIN treatment lineup. It sits alongside the LPP Treatment and Hair Pack as a post-chemical or maintenance conditioning option for professional use.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does Iljin LPP Treatment 1000ml treat in hair?
LPP stands for Lipid, Protein, and Polysaccharide - the three structural components of hair that chemical treatments (perms, color, straightening) disrupt. The Iljin LPP Treatment replenishes these components, reducing breakage, restoring softness, and improving shine after chemical services. At 1000ml it is a professional salon volume with lower cost per application than small retail treatments.
Which Iljin LPP Hair Pack should I choose - Aroma or Chitocyanin?
The Chitocyanin variant adds chitosan and cyanin to the LPP base, providing antioxidant protection alongside structural repair. It is better suited for color-treated or heavily processed hair where oxidation is an ongoing concern. The Aroma variant is a standard conditioning LPP pack with fragrance, appropriate for regular maintenance without a specific color-protection need.
What is the difference between ILJIN Cysteine Wave and Arene Acid?
Cysteine Wave uses an amino acid (cysteine) as the active rather than traditional thioglycolate. This reduces chemical stress on the hair and produces a softer wave, suitable for fine or previously colored hair. Arene Acid is an acid perm using acidic chemistry rather than alkaline, also gentler than traditional alkaline perms and producing a looser curl pattern. Both are less damaging alternatives to standard alkaline perms, with different active mechanisms and texture outcomes.
Does the ILJIN Cream Color Hair Dye 05DB come with developer?
Professional cream color dyes require a separate developer (oxidant) for activation. The ILJIN Cream Color is sold as the color component only; developer is not included and must be sourced separately at the appropriate volume (typically 3%, 6%, or 9% depending on the desired lift and coverage). Mix at the brand's recommended color-to-developer ratio before application.
Is the ILJIN Mist Wax 150ml suitable for fine hair?
Yes. Mist wax in spray format distributes evenly without the weight of cream wax, making it appropriate for fine hair that is easily weighed down. The spray delivery allows a light, even application for texture and light hold without buildup. Use a light pass from 20-30cm away; build up if more hold is needed.
Is ILJIN Volume Magic Straight a permanent straightening treatment?
Volume Magic Straight is a chemical straightening product that reduces curl and adds body without fully flattening hair. Like other chemical straightening treatments, the effect is permanent on the treated hair but new growth comes in at the natural texture. It is not the same as Japanese straightening (which fully eliminates curl) - it is a softening and volumizing straightener.
Is the ILJIN Finisher Hairspray 400ml suitable for home use?
Yes. While the 400ml size is a professional salon format, it is usable at home for anyone who goes through finishing spray regularly. At typical use (2-3 sprays per styling session), a 400ml can covers 60-100 sessions. The Finisher is a setting spray applied after styling is complete, not a thermal protectant used before heat tools.
What shade of hair is ILJIN Cream Color 05DB Natural Black Brown for?
Shade 05DB targets naturally dark brown to near-black hair for grey coverage. The depth level 05 is medium-dark; DB (dark brown) is the base tone. On naturally black hair, it blends greys to a dark brown tone. On naturally dark brown hair, it closely matches the natural shade while covering greys. It will not lighten hair - it is a deposit-only shade at this depth level without bleaching power.
Are ILJIN COSMETICS products on skinsli genuine Korean professional products?
Yes. Skinsli sources ILJIN COSMETICS through verified Korean supplier channels. All 65+ SKUs in this collection are genuine ILJIN COSMETICS products manufactured in Korea for the professional and consumer hair care market.
