What you need to know

After colouring, the difficult balance is cleansing the scalp without making the hair routine feel harsher. No.4 is the cleansing step in Olaplex home care.

The listing describes a nourishing shampoo for chemically treated or damaged hair and calls it colour-safe. Claims about excluded ingredients should still be checked against the pack's current INCI list.

It can prepare hair for a weekly treatment, while everyday frequency should follow scalp oil and dry lengths; washing more often is not automatically more restorative.

  • Verify volume, full ingredients, fragrance, sensitivities and seller authenticity before buying.
  • Use the live bol page for Olaplex No.4 Bond Maintenance shampoo to confirm the final variant, delivery and return conditions.

Hokimi field note: Start with a small amount at the scalp and let the lather pass through the ends instead of repeatedly rubbing fragile lengths.
