Kerargan is built around a clear idea: treat hair by need, not by trend. Every formula is designed to do one job exceptionally well—whether that’s deep hydration, structural repair, nutrition & vitality, volume & density, frizz control & curl definition, scalp detox, or UV/color defense. The result is a routine that feels sensorial, fits busy schedules, and delivers visible results without product overload.

What makes Kerargan different

Targeted architecture — a calibrated blend of humectants (to draw moisture in), emollients (to cushion and smooth), and proteins (to support the cuticle temporarily) in the right ratio for each goal.

pH-smart routines — cleansing that respects the scalp barrier and care steps that help the cuticle lie flatter for gloss and easier detangling.

Short, repeatable protocols — 3–4 steps max: cleanse → treat → seal → protect. Consistency beats complexity.

Responsible claims — clear benefits like “helps reduce breakage” or “supports hydration balance,” never over-promising miracle “cures.”

The ranges (one need, one promise)

Coco — Hydration & softness

For tight, thirsty, rough-feeling lengths. Expect immediate slip, softer touch, and a healthier-looking sheen. Ideal for weekly moisture resets or after sun exposure.

Keratin — Repair & anti-breakage

For chemically processed or heat-stressed hair. Hydrolyzed keratin and amino acids reinforce weak spots so hair feels stronger and smoother, with fewer snags during brushing.

Castor — Nutrition & vitality

For dry, brittle lengths that won’t hold hydration. Castor-rich care helps lock in moisture, improving suppleness and the look of resilience over time.

Biotin & Collagen — Volume & density

For fine or flat hair. Lightweight body and touchable lift, designed to add presence without waxy residue or stiff feel.

Argan — Anti-frizz & curl definition

For curls, coils, and unruly textures. Disciplines halo frizz, enhances definition, and keeps hair soft through humidity swings.

Mud — Scalp detox & balance

For oily roots, buildup, or dull, heavy hair. Mineral-rich care purifies the scalp environment and resets roots to light, airy freshness—without stripping lengths.

UV — Color & sun protection

For color-treated or frequently exposed hair. Helps shield from UV, chlorine, and salt, supports softness, and preserves color vibrancy between salon visits.

Build your routine by goal

Hydrate (for dry/dehydrated)

Gentle cleanse (lukewarm water; avoid harsh scrubbing).

Moisture mask (Coco) 10–15 min; low heat or a warm towel boosts payoff.

Seal with a light leave-in on mid-lengths and ends.

Protect from heat/UV whenever styling or heading outdoors.

Repair (for damaged/high porosity)

Keratin shampoo (focus on scalp; let lather run through lengths).

Keratin mask 10–15 min; detangle with a wide-tooth comb in sections.

Rinse thoroughly; finish cool for extra shine.

Always add thermal protection before irons or blow-dryers.

Nourish (for brittle, dull lengths)

Hydrating cleanse.

Castor mask once or twice weekly to help “hold” moisture longer.

Light serum on ends to minimize daily wear and tear.

Lift (for fine/flat)

Volume-friendly shampoo; avoid scorching hot water.

Light conditioner 5–8 min, applied from mid-lengths down.

Meticulous rinse + brief cool shot to keep roots buoyant.

Define (for curls/coils)

Low-friction cleanse; don’t rough up lengths.

Argan mask; detangle with fingers or a wide-tooth comb.

Layer a curl cream/gel; diffuse on low heat or air-dry.

Reset (for oily roots / product buildup)

Mud care on scalp 5–8 min, then gentle shampoo.

Light mask only on mid-lengths/ends to avoid weighing roots.

Ingredient playbook

Humectants (glycerin, aloe, panthenol): draw moisture into the fiber for flexibility.

Emollients (coconut, argan, castor oils; lightweight esters): cushion, smooth, add slip for easier detangling.

Proteins (hydrolyzed keratin, amino acids, peptides): temporarily support fragile areas and enhance surface polish.

Protectives (UV filters, antioxidants): help defend color and shine against sun, chlorine, and salt.

Porosity-led guidance

High porosity (very damaged/processed): favor Keratin + richer emollients; longer dwell (up to 15–20 min) with low heat.

Medium porosity: alternate hydration (Coco/Castor) with strengthening (Keratin).

Low porosity: keep textures lighter, shorter dwell times, and use warmth sparingly to avoid buildup.

Heat & styling best practices

Limit peak temperatures; more passes at low heat beat one scorching pass.

Always apply heat protection on dry, detangled hair for even coverage.

Finish styles with a cool shot to help the cuticle lie flatter and reflect more light.

Seasonal strategy

Spring: weekly scalp reset (Mud) + hydration top-ups.

Summer: UV defense before exposure; after-sun mask + clear rinse post swim.

Autumn: alternating Castor (nutrition) and Keratin (strength) to recover from summer stress.

Winter: richer textures if indoor air is dry; avoid very hot water that strips moisture.

One-week reboot plan

Day 1 — Hydrating cleanse + light conditioner; cool finish.

Day 2 — Moisture mask 10–15 min; minimal heat styling.

Day 3 — Leave-in only; braid or protective style.

Day 4 — Keratin care (short dwell) if hair is fragile; thorough rinse.

Day 5 — Rest day; serum on ends only.

Day 6 — Curl/volume focus depending on your texture.

Day 7 — UV protection if outdoors; after-sun care if swimming.

FAQ (straight answers)

Do Kerargan formulas “fix” damage permanently?

They improve feel and appearance, help reduce breakage, and smooth the surface, but split ends still need a trim. Sustainable results come from consistent care + heat/UV protection.

Will fine hair feel heavy?

Use lighter textures and shorter dwell times, apply from mid-lengths down, and rinse meticulously. Lift should remain airy, not coated.

How often should I mask?

Maintenance: once weekly. Intensive phases: up to twice weekly, alternating moisture/nutrition with strengthening so hair stays supple and resilient.
