CONCRED W Hair Mist vs Hair Serum: Two Mist Routines and What 1% and 5% Mean

CONCRED W Hair Mist and Hair Serum: the layered mist has in-bath and leave-in routes; the white-pump serum is leave-in, mainly for ends. Their 1% and 5% describe different ingredient blends. Japan Drugstore Guides
Look for W HAIR MIST on the CONCRED bottle first. This particular mist has two ways to fit into a hair-care routine, with different rinsing steps. The separate HAIR SERUM has its own leave-in instructions.

IreneI’m Irene, a Taiwanese pharmacist working in a Japanese drugstore. This guide connects the two labels with their application steps and percentage claims, so you can choose a place for them in your existing routine.

Start with the step you want to add.

  • Before your usual rinse-out conditioner: consider the mist’s in-bath route.
  • A spray on towel-dried or dry hair: consider the mist’s leave-in route.
  • A product spread by hand, mainly through the ends: compare the serum, which the brand positions for curly, wavy and dry hair.

This guide covers these two selected Japanese-market products. The current CONCRED range also includes a hair oil, shampoos and other treatments. Match the full name before borrowing instructions from another bottle.

Identify the bottle by its name

  • W Hair Mist | 100mL
    Japanese label: ハイインテンシブケア シルキーモイスチャー 1%濃度 Wヘアミスト
    JAN barcode: 4571242819256. A spray with two separate liquid layers.
  • Hair Serum | 100mL
    Japanese label: ハイインテンシブケア ストレート 5%濃度 ヘアセラム
    JAN barcode: 4571242819263. Dispense into your hand before applying.

Both were listed at ¥1,980 including tax for an ordinary one-time purchase from the official online shop on November 11, 2026. Branch prices and stock can differ. With the same stated volume and checked price, application style is more useful than the larger percentage on the label.

One W Hair Mist, two routes

CONCRED W Hair Mist 100mL with visible liquid layers and a 1% ingredient-blend callout
Image: MatsukiyoCocokara & Co., via its July 23, 2025 PR TIMES release. The 1% refers to a specified combined ingredient amount, explained below. Check the packaging of the product you buy.

Shake well to mix both layers before use. Hold the spray about 10–15cm from your hair. Then follow the route that matches your routine:

Route A: during washing

Shampoo, then remove excess waterSpray an appropriate amount through your hairApply your rinse-out conditioner directly afterwardRinse togetherThe official sequence puts conditioner over the mist. It does not add a separate rinse between those two steps.

Route B: leave-in care

Start with towel-dried or dry hairSpray an appropriate amount and distribute evenlyDry your hair; no rinse

The directions allow small additions to areas where damage is a concern. This does not call for another full application everywhere.

Original workflow based on the Japanese directions. “2WAY” describes two permitted routes; it does not instruct you to repeat both at every wash.

The checked directions give no universal spray count or waiting time. Choose a place in your routine first. Adding one change at a time also makes it easier to judge how your hair feels afterward.

Hair Serum: apply by hand, mainly to the ends

CONCRED Straight Hair Serum 100mL with a TOSTEA 5% ingredient-blend callout
Image: MatsukiyoCocokara & Co., via its July 23, 2025 PR TIMES release. The 5% includes the water base in the TOSTEA blend, rather than a single pure ingredient. Check the packaging of the product you buy.

The brand positions this serum for curly, wavy and dry hair. Take an appropriate amount in your hand and work it mainly through the ends. It can be used on wet or dry hair as leave-in care.

The checked instructions give no fixed pump count and require neither blow-drying nor a styling iron. Treat “Straight” as the product’s positioning for everyday hair management, without expecting permanent straightening or a change to your natural curl pattern.

Do you need to buy both?The launch announcement describes standalone and combined use. If you choose to layer them after washing, the brand places mist before serum. That is an option, not a requirement to complete a set. If your existing leave-in product already suits you, start by deciding which additional step you actually want.

What do 1% and 5% measure?

The mist’s 1% refers to the brand’s specified blend, whose listed components include hydroxyethyl urea, gamma-docosalactone and diethyl sebacate. It does not mean 1% of each ingredient or a pure-active concentration.

The serum’s 5% refers to the TOSTEA blend. The brand’s footnote includes diammonium aminoethyl thiosuccinate (アミノエチルチオコハク酸ジアンモニウム) and water as its base. It should not be shortened to “5% pure active ingredient.”

These percentages describe different mixtures, so they cannot establish which product works better or by how much. “Spray or hand-applied serum?” and “During washing or afterward?” are more useful buying questions.

Ingredients and precautions

Both official ingredient lists include fragrance and silicones, but the formulas differ. The mist lists hydroxyethyl urea and gamma-docosalactone; the serum lists the TOSTEA ingredient, cetearyl alcohol and several silicones. An individual ingredient is not enough to predict which whole formula will suit you.

  • If you have a known reaction to fragrance or a particular ingredient, check each full list and the purchased pack.
  • Both official shop pages say to stop use if the cosmetic does not suit your skin. Avoid storage in extreme heat, extreme cold or direct sunlight.
  • This is cosmetic hair care, with no guarantee of permanently mending split ends, straightening hair or treating a scalp condition.
  • Follow the purchased product’s complete directions and precautions. This guide supplies no styling-tool temperature or extra heating step.

Before buying, check the full name, 100mL volume and the step where you plan to use it. For W Hair Mist, remember to shake first and keep its two application routes separate.
