Resistance Bain Force Architecte Shampoo

Caution 2.5 / 5

A verified salon shampoo for damaged hair with real conditioning support and a strong fragrance footprint. It is a plausible choice for weakened hair that tolerates scented, higher-cleansing formulas, but it is less suitable for fragrance-sensitive or very dry scalps.

Hair & scalp

How it’s judged

Scored for hair & scalp — based on what its ingredients contribute.

What it may help with

Cleansing i3.5 / 4

Whether it helps remove dirt, oil, sweat, product residue, or buildup from hair or scalp — surfactants and cleansing agents score here.

From Sodium Laureth Sulfate, Disodium Cocoamphodiacetate, Magnesium Laureth-8 Sulfate, Magnesium Laureth Sulfate

Conditioning i3.5 / 4

Whether it makes hair feel softer, smoother, or more manageable — emollients, silicones, cationic polymers, and oils.

From Behentrimonium Methosulfate, Tamarindus Indica Seed Polysaccharide, Glycerin, 2-Oleamido-1,3-Octadecanediol

Detangling i3.5 / 4

Whether it reduces friction so hair is easier to comb or brush.

From Behentrimonium Methosulfate, Tamarindus Indica Seed Polysaccharide, Hydroxypropyl Guar Hydroxypropyltrimonium Chloride, Quaternium-33

Dandruff control i2.5 / 4

Whether it helps reduce dandruff, flaking, or Malassezia-related scalp issues — usually recognized anti-dandruff actives.

From Salicylic Acid

Anti frizz i2.5 / 4

Whether it helps reduce frizz, flyaways, humidity effects, or rough hair appearance.

From Behentrimonium Methosulfate, Glycerin, Citric Acid

Things to watch

Sensitization i3.5 / 4

Risk of allergic contact dermatitis or immune-based scalp reactions — fragrance, preservatives, hair dyes, and botanicals may score here.

From Butylphenyl Methylpropional, Citronellol, Fragrance, Linalool

Scalp irritation i2.5 / 4

Risk of itching, burning, redness, dryness, or discomfort on the scalp.

From Butylphenyl Methylpropional, Fragrance, Sodium Laureth Sulfate, Alcohol Denat.

Hair dryness i2.5 / 4

Whether it may make hair fibers feel dry, rough, brittle, or less flexible.

From Alcohol Denat., Sodium Chloride, Citric Acid

Scalp dryness i2.5 / 4

Whether it may dry out the scalp, strip oils, or worsen flaking and tightness.

From Alcohol Denat., Sodium Chloride, Citric Acid

Breakage damage i1.5 / 4

Whether it can contribute to weakening, brittleness, or breakage — especially harsh treatments, strong oxidizers, relaxers, and high-pH systems.

From Alcohol Denat.

About this product

This is a rinse-off strengthening shampoo for damaged, brittle, split-end-prone hair. The verified ingredient list shows a cleansing base with conditioning polymers, some humectant/support ingredients, and a small amount of salicylic acid, but it is not a minimalist or fragrance-free formula. The evidence comes from Kérastase product pages and a retailer listing that exposed the full INCI list for the same 250 ml variant.

Good signs
  • Targeted for damaged hair with conditioning and smoothing support, not just basic cleansing.
  • Includes film-forming and cationic conditioning agents that can reduce roughness and improve slip.
  • Contains humectant/support ingredients that may help limit the feel of dryness in a wash product.
  • Has salicylic acid, which can help with scalp buildup in some users.
Watch-outs
  • Contains a substantial fragrance system with declared allergens, so it is not a good fit for fragrance-sensitive use.
  • The cleansing base is relatively strong, which may be too stripping for very dry or highly processed hair.
  • Repair claims should be read as cosmetic support rather than true hair reconstruction.
  • Contains alcohol denat., which may add to a drying feel in some hair types.
Best for
  • Damaged or weakened hair that benefits from a stronger cleansing shampoo with conditioning support.
  • Users who want a salon-style repair shampoo and are not sensitive to fragrance.
  • Scalps with some buildup, if tolerated well.
  • normal
  • dry
  • oily
  • sensitive
How to use it
  • Use on wet hair, massage into the scalp, then rinse thoroughly.
  • Pair with a conditioner or mask if lengths are dry, bleached, or fragile.
  • Patch testing is reasonable for fragrance-sensitive or reactive scalps.
