Heat-styled hair · molecular reconstruction
Your hair snaps when you brush it — and you're not giving up the iron.
That snapping isn't dryness. Heat breaks the disulfide bonds inside the cortex — the structure that lets hair bend instead of break. Coatings can't rebuild those bonds. ANATOMY's click chemistry forms new ones — measured by SGS Proderm at a 135% strength increase on bleached hair, the hardest case there is.
The One-Cycle Guarantee — run the Complete System through one full 60-day cycle. If your hair isn't visibly different, we refund it.
Independently measured · not a consumer panel · also −15% E‑modulus (bends further before it breaks).

View detailsNew to ANATOMY? Most people start with the Leave-In.
Where should I start?
If you style with heat regularly, start with the Leave-In: it stays on the hair longest and is the most practical single-step entry. If your hair is already compromised (breakage, porosity, colour), the complete system rebuilds fastest because each step primes the next.
Is heat protection not enough?
Protection limits new damage. It does not rebuild bonds that are already broken. Reconstruction comes first; protection works better once the fiber underneath is less compromised.
What if it doesn't work for me?
Every order is covered by The One-Cycle Guarantee — run the system through one full 60-day cycle. If your hair isn't visibly different, we refund it.
Rebuild the structure underneath the styling.
Begin the full protocol for the fastest rebuild, or start with the Leave-In if you want one step first. Either way, you're treating the damage, not just coating it.
