Olaplex Healthy Hair Discovery Set — travel-size bond-building kit with N°3PLUS, N°4 & N°5 for repair and shine

Olaplex Healthy Hair Discovery Set is a complete starter routine that repairs bonds, hydrates, soothes the scalp, and styles for smoother, shinier hair in one curated kit.

This discovery collection brings together Olaplex’s most trusted formulas — including the updated N°3PLUS pre-shampoo treatment, N°0.5 scalp protectant, the #1 N°4 shampoo and N°5 conditioner, plus styling favorites N°6 and N°7. Designed to work as a sequence, the set targets breakage, dryness, frizz, and heat styling protection with Olaplex’s patented bond-building technology. It’s sized and selected to let you test the system before committing to full sizes.

How does the N°3PLUS treatment fit into my routine?

N°3PLUS is a concentrated pre-shampoo repair step meant to strengthen hair in minutes. Apply to dry or damp hair, leave for the recommended time, then rinse and follow with the shampoo and conditioner for best results.

• Use as the first step to target broken bonds and visible damage.
• 3-minute application for a quick at-home repair boost.
• Works before shampooing to maximize bond-repair benefits.

Will the N°4 and N°5 duo reduce breakage and hydrate effectively?

N°4 (shampoo) and N°5 (conditioner) are formulated to cleanse gently while rebuilding strength and restoring moisture. Together they help smooth the hair cuticle, reduce tangling, and leave strands more manageable after rinsing.

• N°4 cleans without stripping natural moisture, preparing hair for conditioning.
• N°5 delivers targeted hydration to improve softness and manageability.
• Regular use supports reduced breakage and smoother texture over time.

What do N°0.5, N°6 and N°7 do for scalp health and styling?

N°0.5 is a lightweight scalp serum that soothes and primes the hair, while N°6 and N°7 are styling concentrates that smooth, reduce frizz, and add shine. N°7 also offers heat protection up to high temperatures, making it ideal before blow-drying or using hot tools.

• N°0.5 calms and nourishes the scalp, creating a healthy base for hair growth.
• N°6 tames frizz and conditions hair for a softer finish during styling.
• N°7 adds instant shine and helps protect hair from heat up to 450°F/232°C when styling.

How quickly will I see improvement and how should I use the set?

Many users notice smoother, shinier-looking hair after the first full routine; cumulative strengthening and reduced breakage develop with consistent use. Follow the sequence: N°3PLUS pre-shampoo treatment, N°4 shampoo, N°5 conditioner, N°0.5 scalp primer, then styling with N°6 and N°7 as needed.

• Start with N°3PLUS before shampooing for targeted repair.
• Follow with N°4 and N°5 for cleansing and hydration.
• Finish with N°0.5 on the scalp and N°6/N°7 for styling and protection.

Who is this for: The Olaplex Healthy Hair Discovery Set is ideal for anyone seeking a trial-sized, science-backed routine to address visible damage, dryness, frizz, or heat styling concerns. It suits all hair types — color-treated, chemically processed, or natural — when you want a coordinated system to rebuild strength, improve texture, and add shine without guessing which products to pair. Use it as an introduction to Olaplex bond technology or as a travel-ready kit to maintain healthier-looking hair between salon visits.
