Description

PROHALL's flagship professional keratin treatment — the protocol that launched everything. Built around a proprietary glyoxylic acid-keratin complex that rebuilds broken disulphide bonds inside the cortex in the same way formaldehyde-based treatments do, but without releasing any toxic compounds at activation temperature (220°C).

Hydrolyzed keratin fragments (<1,000 Da) penetrate below the cuticle. Argan oil seals the cortex flat. A precision 18-amino-acid complex fills micro-damage and locks moisture in. Over the 72-hour post-application window, the bonds consolidate — permanently. Treated hair stays treated until it grows out.

Expect: 60–80% frizz reduction · 4× measured shine · 10–12 weeks of smoothness through daily washing, styling, humidity, and swimming.

17 oz / 500 ml · Formaldehyde-free · Color-safe · Vegan

How to use
  1. Clarify — Wash twice with sulfate-free clarifying shampoo. No conditioner. Rinse completely.
  2. Towel-dry to ~80% moisture. Section into 4 parts. Wear the included gloves.
  3. Apply with the applicator brush — root to tip, fully saturating each section.
  4. Comb through to distribute evenly.
  5. Leave 20 minutes. Use a shower cap for coarse/resistant hair.
  6. Blow-dry completely on medium heat. Do not rinse.
  7. Flat-iron at 220°C in 2 cm sections, 3–5 slow passes each until glassy.
  8. Wait 72 hours. No water, no ties, no clips. This is when the bonds consolidate.
  9. Rinse and reveal — shine, restored.

Maintenance rule: Sulfate-free shampoo only. This one change adds 3–4 weeks to your results.

FAQ

Is it safe for color-treated hair? Yes — formaldehyde-free, pH-balanced, actually extends color vibrancy by sealing dye molecules in the cortex.

How long does it last? 10–12 weeks with sulfate-free maintenance. More with a shower filter.

Does it straighten hair? It smooths and repairs — 60–80% frizz reduction. Keeps your natural pattern intact. Use a flat iron for pin-straight days.

Why can't I wash for 72 hours? The glyoxylic acid bonds take 48–72 hours to fully consolidate. Water interrupts the chemistry and locks any fold/crease permanently into the hair.

The benefits

Why your hair needs this.

Six clinical benefits — all backed by peer-reviewed research, not marketing.

Bond repair

Hydrolyzed keratin penetrates the cortex to rebuild broken disulphide bonds — the biggest factor in hair strength and elasticity.

◦ 98% less breakage after first use

Mirror shine

Argan oil seals the cuticle flat — creating the reflective surface that makes hair visibly glossy under any light.

◦ 4× more shine measured

Frizz control

Amino acids rebalance hair's moisture profile so humidity can't swell the shaft and trigger frizz.

◦ 12 weeks frizz-free

Color safe

Formaldehyde-free and pH-balanced — preserves your color, no strip-out, no dulling, no oxidative damage.

◦ Safe up to 10 sessions / year

Heat protection

Keratin coating raises your hair's heat-damage threshold from 180°C to 230°C — safe for daily styling.

◦ Up to 230°C tolerance

Dermatologist safe

Zero formaldehyde, parabens, sulfates, or silicones. Safe for sensitive scalps, color-treated hair, and daily use.

◦ Derm-tested panel approved

THE FORMULA

Four actives, one mechanism.

Every ingredient earns its place. Nothing decorative, nothing filler — each molecule contributes to a specific step in the bond-repair cascade.

ACTIVE · BOND REPAIR

Hydrolyzed Keratin

Keratinum Hydrolysatum

Fragmented protein molecules (<1,000 Da) penetrate below the cuticle and form new covalent bonds with damaged protein chains. Structural repair — not surface coating.

Benefit Rebuilds disulphide bonds
ACTIVE · CROSSLINKING

Glyoxylic Acid Complex

Acidum Glyoxylicum

Our proprietary formaldehyde-free crosslinker. Performs the same bond-reformation chemistry as formaldehyde — without releasing toxic vapor at heat activation.

Benefit Formaldehyde-free crosslinking
BOTANICAL · NUTRITION

Argan Oil

Argania Spinosa

Cold-pressed, cold-chain preserved. Rich in vitamin E and squalene. Seals the cuticle flat creating measurable optical shine, and deposits lipid nutrition into the cortex.

Benefit Mirror shine & softness
ACTIVE · AMINO MATRIX

18-Amino Acid Complex

Acidi Amino Complexus

Precision blend mirroring hair's natural keratin composition. Fills micro-damage, rebalances electrical charge (a major frizz driver), and locks moisture inside the cortex.

Benefit Lasting frizz control

Loved by customers

Is this safe for color-treated hair?

Yes. Our formula is 100% formaldehyde-free and pH-balanced at 6.5–7.0 — the range that preserves dye molecules without oxidizing or lifting color. Many clients apply Miracle Therapy 2 weeks after coloring — the treatment seals the cuticle flat around dye molecules, extending color vibrancy by an additional 2–3 weeks.

◦ SAFETY
How long do the results last?

10–12 weeks on average. Three factors determine longevity:

  • Shampoo — sulfate-free is non-negotiable. Sulfates are the number-one cause of early fading. This single change adds 3–4 weeks.
  • Water quality — chlorine and hard mineral water accelerate bond degradation. A shower filter helps significantly.
  • Heat — daily flat-ironing above 230°C gradually degrades the keratin coating.
◦ DURATION
Will it straighten my hair completely?

Miracle Therapy smooths and repairs — it doesn't break your natural curl pattern (that's what chemical relaxers do, and what causes long-term damage). Expect 60–80% frizz reduction and softer, more defined wave or curl. For pin-straight results, finish with a flat iron after rinsing — the treatment makes straightening much easier and longer-lasting.

◦ RESULTS
How is it different from Brazilian Blowout?

The crosslinking agent is completely different. Brazilian Blowout uses formaldehyde — a Group 1 IARC carcinogen that releases toxic vapor above 60°C (which is why salon treatments require ventilation and PPE). Our glyoxylic acid-keratin complex performs the identical crosslinking chemistry without releasing aldehydes at activation temperature. Same bond-repair mechanism. Zero toxicity.

◦ INGREDIENTS
What hair types does it suit?

All textures benefit. Most dramatic transformations on:

  • Wavy-to-curly (2A–3C) — frizz control and shine
  • Chemically treated (colored, bleached, relaxed) — structural bond repair
  • Heat-damaged — elasticity restoration
  • Humidity-reactive — impermeable cuticle seal

Fine hair also benefits — the results are lighter and body-preserving.

◦ HAIR TYPES
Why can't I wash my hair for 72 hours?

The glyoxylic acid crosslinks take approximately 48–72 hours to fully consolidate and anchor into the cortex. During this window, the bonds are still forming. Water disrupts the chemical process and locks any wave, crease, or fold permanently into the treated hair. This isn't a recommendation — it's the mechanism. Sleep on silk. Avoid tucking behind ears. No glasses resting in hair.

◦ PROTOCOL
How often should I reapply?

Every 8–12 weeks. More frequent application (6–8 weeks) is safe and sometimes used by professionals on very resistant or coarse hair for a cumulative strengthening effect. Earlier than 6 weeks won't add benefit — the repair cycle completes in a single protocol.
