Olaplex no 4 shampoo

Select No 4 Bond Maintenance Shampoo if you want to address bond maintenance while cleansing. It’s suitable for all hair types seeking strength and resilience from within. Consider your scalp type and level of dryness; if you have very oily or extremely curly hair, you may need to pair it with No 5 conditioner for optimal results. Use it consistently, alternating with conditioner to maintain moisture balance.

The key complexity is its bond-maintenance chemistry. It aims to rebuild disulfide bonds within hair damaged by coloring, heat, or mechanical stress, improving elasticity and strength. The formula is designed to be gentle, with hydrating ingredients that help reduce breakage. For best results, pair No 4 with the corresponding No 5 conditioner and follow the recommended use cycle to support healthy, resilient hair.

Beginners should start with a regular cleansing routine, using No 4 a few times per week, while gradually increasing as needed for hair repair. Seasoned users may integrate it into a full bond-maintenance regimen with complementary products like conditioners or treatments. Pay attention to how your hair responds; if you notice buildup, adjust frequency or rinse thoroughly. Consistency is key to achieving the targeted bond-rebuilding effects.

Apply a generous amount to wet hair, massaging into scalp and through lengths, then rinse. For enhanced results, follow with No 5 Conditioner to lock in moisture and bonds. If you use other Olaplex tools, follow the prescribed order in the set. Avoid mixing with harsh ingredients that may counteract bond repair, and adjust frequency based on your hair’s needs.

This shampoo is designed to be gentle, but if you have sensitive or reactive skin, perform a patch test before full application. Look for fragrance-free or hypoallergenic variants if you are prone to irritation. If irritation occurs, discontinue use and consult a dermatologist. Always check ingredient lists for potential allergens you may react to.

Store in a cool, dry place away from direct sunlight to maintain formula stability. Close the cap tightly after use to prevent contamination. Use within the recommended period after opening and avoid transferring to other containers that may introduce bacteria. Keep out of reach of children and follow local guidelines for recycling the packaging.
