No 5 Curl

No 5 Hydrating Curl Conditioner is made for coily, curly, and wavy hair across every pattern and porosity level. Powered by Olaplex’s patented 3D Bond Shaper™ and Hydra-Define™ Technology, it works throughout the hair to strengthen vulnerable areas, smooth the cuticle, lock in moisture, and support softer, more defined curls while helping protect length over time. The fragrance is a reimagined take on Olaplex’s signature scent, opening with crisp Sugared Mint and bright Grapefruit Zest and Ginger before settling into a sophisticated base of Crushed Sage.

When used with No 4 Hydrating Curl Shampoo, users experienced seven days of hydrated curls, 50% less frizz—even in high humidity—and instantly stronger hair with less breakage. In testing, 96% of users also agreed that their hair was easier to detangle.

The silicone-free, protein-free formula is Trichologist Approved, Stylist and Dermatologist Tested, vegan, color-safe, and suitable for chemically treated hair. It is also free from SLS/SLES, parabens, phthalates, phosphates, and MIC/MIT.
