You read about the reconstruction. Here's what it does to damaged hair.
ANATOMY rebuilds the broken bonds inside the cortex with Nobel-recognised click chemistry — independently measured at SGS Proderm at a 135% tensile-strength increase on bleached hair, versus untreated. Not a surface coating, and not a dupe of Olaplex or K18 — the next generation. Take the 60-second match to see where to start, or read the science first.
Microscopy: a damaged fiber before reconstruction
Two bonds per molecule
Thiol-yne click chemistry forms covalent crosslinks that single-bond chemistry can't.
90% cortex penetration
The work happens inside the fiber — not just on the surface.
The reconstruction brief
Get the 1-page science breakdown — and 10% off your first order.
The mechanism, the measured proof (135% vs untreated; 13–15% vs the leading bond builder), and a protocol matched to bleach, heat, or breakage — plus a private first-order code. Sent by email, no filler.
Is bond repair — Olaplex, K18 — enough?
What bond repair does (Gen 2)
Olaplex and K18 reconnect or fill some damage with single-bond or peptide chemistry. Real, but limited: one new bond per molecule, much of it where it can wash away.
Why it plateaus
Patching can't fully explain a structural strength gain. Independently, ANATOMY tested 13–15% stronger than hair treated with the leading bond builder — the headroom it leaves on the table.
What reconstruction does (Gen 3)
ANATOMY forms two new covalent bonds per molecule, deep in the cortex. The upgrade, not a swap — and the result is structural: 135% stronger, measured.
The mechanism, in three steps
If you've used enough repair products, skepticism is earned — most improve feel, then the weakness returns once the cosmetic finish wears off. We report what we measured, not a wellness promise: if the result is stronger hair, the mechanism has to account for the inside of the fiber, not only the outside.
Damage breaks bonds in the cortex
Bleach, color and heat don't just roughen the surface — they break the disulfide and structural bonds that hold the fiber together inside.
Aminalyl S + Pro-amino X find the damage
Two molecules do the work: Aminalyl S rebuilds the bridges between separated keratin chains; Pro-amino X forms a new crosslink network via thiol-yne click chemistry.
The result shows up under load
If reconstruction is real, it shows up when the fiber is stressed — a measured 135% stronger, and roughly 3× more flexible than the leading bond builder.

Is ANATOMY just a dupe of Olaplex or K18?
No — it's the next generation, not a swap. Olaplex and K18 patch or reconnect with single-bond or peptide chemistry. ANATOMY forms two new covalent bonds per molecule via Nobel-recognised click chemistry, deep in the cortex. Independently tested: 135% stronger than untreated, and 13–15% stronger than the leading bond builder.
Does “135% stronger” mean my hair is 135% healthier?
No, and we won't pretend it does. It's a specific instrument reading — a 135% increase in tensile strength on bleached hair, measured at SGS Proderm versus untreated. We report what we measured, not a wellness promise.
Where should I start — and what if it doesn't work for me?
If you're new, the Leave-In is the strongest single-step entry ($85). If your hair is already compromised, the complete system rebuilds fastest. Either way you're covered by a 30-day money-back guarantee — if it's not for you, we refund it. Not sure? The 60-second consultation matches you to the right start.
