Start a visible-repair regimen with Olaplex’s bestsellers: N°3PLUS pre-shampoo treatment, the #1 cleansing and conditioning duo N°4 and N°5, the scalp-soothing concentrate N°0.5, and styling powerhouses N°6 and N°7. This curated value set combines repair, moisture, heat protection, and shine support into one kit so you can address breakage, frizz, and dullness across coily, curly, wavy, and straight hair.

How quickly will I see repair and reduced breakage?

Many users notice improved texture and less snapping after the first use of N°3PLUS followed by the N°4 and N°5 ritual. N°3PLUS is formulated as a concentrated pre-shampoo treatment designed for short contact time; combine it with the full wash and conditioning routine to build cumulative improvements.

• N°3PLUS: targeted 3-minute pre-wash repair treatment
• N°4: sulfate-free shampoo to gently cleanse and fortify
• N°5: conditioner to hydrate, detangle, and reduce breakage
• Repeat weekly or as needed for progressive strengthening

Can this kit protect hair when I heat style?

Yes — N°6 and N°7 are styling allies that smooth, reduce frizz, and add surface shine while providing thermal defense for daily styling. N°7 is formulated to help protect hair from heat tools, and N°6 creates a smoother finish that complements protection and manageability.

• N°7: lightweight oil that boosts shine and heat protection up to 450°F/232°C (tested on bleached hair)
• N°6: leave-in styling cream for smoother, softer hair and frizz control
• Use N°6 on damp hair and N°7 on dry or damp hair for flexible results

What role does N°0.5 play in scalp and strand health?

N°0.5 is a concentrated bond-building serum formulated to soothe and visibly improve the appearance of hair texture and scalp comfort when used as part of a layered repair system. It primes hair to receive the benefits of the follow-up treatments in the set for a more complete repair cycle.

• Apply N°0.5 to damp hair and scalp before styling for immediate calming effect
• Pairs with N°3PLUS and in-shower products to amplify bond rebuilding
• Helps hair appear softer and healthier with regular use

How should I use these products together for best results?

Follow a stepwise routine: apply N°3PLUS as a pre-shampoo treatment, cleanse with N°4, condition with N°5, apply N°0.5 to damp hair and scalp, then style with N°6 and/or N°7. Consistent use creates the best cumulative improvements in strength, moisture, and smoothness.

• Step 1: N°3PLUS on dry hair for 3 minutes, then rinse and shampoo
• Step 2: N°4 wash, N°5 rinse and detangle
• Step 3: N°0.5 as a leave-on primer; finish with N°6 and N°7 for styling
