Olaplex Healthy Hair Discovery Set — 6-piece bond-building kit for repair, hydration & frizz control

This curated collection brings together Olaplex's bestselling formulations—N°3PLUS, N°0.5, N°4, N°5, N°6 and N°7—so you can rebuild, maintain and style hair using the same bond-building technology salon pros rely on. The set pairs a fast-acting pre-shampoo treatment with cleansing, conditioning, scalp care and two styling products to address damage, moisture and frizz without layering conflicting ingredients.

How quickly will I notice improvements after using the set?

Many users observe improved manageability and visible smoothing after the first full routine; N°3PLUS is formulated to start repairing in minutes when used as directed. Cumulative benefits for strength, reduced breakage and shine typically appear over repeat use as the bond-repairing ingredients act on weakened areas of the hair fiber.

• N°3PLUS: 3-minute pre-shampoo repair treatment
• N°4 + N°5: cleansing and hydration to reduce breakage
• N°0.5: immediate scalp soothing and protection
• N°6 + N°7: instant smoothing, frizz control and heat protection

Which products should I use first and how do they fit into a routine?

Start with N°3PLUS as a pre-shampoo step to target weakened bonds, then rinse and cleanse with N°4. Follow with N°5 conditioner, treat the scalp with N°0.5 as needed, and finish styling with N°6 and N°7 for smoothness, softness and heat protection.

• Pre-shampoo: N°3PLUS applied to dry hair for three minutes
• Wash: N°4 shampoo to cleanse without stripping
• Condition: N°5 to hydrate and detangle
• Scalp care & style: N°0.5, then N°6 and N°7 for finishing

Is this set suitable for colored, chemically treated, or heat-styled hair?

The kit is formulated to be compatible with color-treated, lightened and heat-styled hair: Olaplex bond-building ingredients work on strands weakened by bleaching, chemical services and thermal tools. Individual responses vary, but the set is designed to support strength, moisture retention and styling resilience across common salon and home treatments.

• Safe to use alongside color and chemical services
• N°3PLUS targets damage often caused by bleaching or processing
• N°7 provides heat protection up to 450°F/232°C for styling tools
• Routine reduces breakage and improves manageability

How do I know which products in the set to use daily versus as a treatment?

N°4 (shampoo) and N°5 (conditioner) are intended for regular use according to your washing schedule. N°3PLUS is a concentrated repair treatment used less frequently—follow label directions—while N°0.5, N°6 and N°7 are targeted treatments and styling aids you can add as needed for scalp care, smoothing and thermal protection.

• Daily or routine: N°4 shampoo and N°5 conditioner
• Periodic intensive repair: N°3PLUS pre-shampoo treatment
• As-needed scalp care: N°0.5 for instant soothing
• Styling protection: N°6 and N°7 before heat styling

Who is this for: The Olaplex Healthy Hair Discovery Set is ideal for anyone seeking a comprehensive introduction to bond-repairing hair care—people with chemically treated, heat-styled or naturally dry and weakened hair will find it especially useful. It suits anyone who wants a practical, step-by-step regimen that combines short treatments with everyday cleansing, conditioning and styling products, all in a compact kit for trial, travel or to establish a new baseline routine.
