Step 02 of 05 · The LINEONE ritual

The LINEONE ritual
Five products, one sequence. Built to be used together on extension-worn hair.
Why it's safe on extensions
Formulation
Sulfate-free, paraben-free, color-safe
No sulfates to strip color from blends, and nothing that softens or slips a keratin bond over repeat washes.
Method coverage
Keratin, tape-in, hybrid, sewn-in
Formulated for every method we install. Apply mid-length to ends and keep product off the bond line.
