Most treatments rely on vague “hydrolyzed proteins” or “keratin complexes” — broad blends meant to coat damage, not explain it.
When those don’t work, it’s easy to assume the damage is irreversible.
But your hair doesn’t need random protein to feel normal again.
It needs L-Cysteine — the specific amino acid that forms elastic disulfide bonds.
Bounce supplies that exact building block, so hair can regain flexibility instead of feeling lifeless and beyond repair.
