Real Repair. Visible Results.
Stop settling for shampoos that only coat the surface and hide damage for a day. Olaplex No.4 + No.5 works inside the strand — using patented bond-building technology to find broken bonds and relink them, wash after wash. The No.4 shampoo cleanses without stripping; the No.5 conditioner hydrates, detangles, and seals. The result is hair that's stronger, smoother, and visibly healthier — on every hair type.
Stronger Hair, Every Wash.
This isn't a quick-fix mask — it's daily maintenance that compounds. With regular use you'll see less breakage, more shine, softer texture, and easier detangling. It's sulfate-free, paraben-free, vegan, and cruelty-free, and safe for colored, curly, fine, and chemically-treated hair — so the whole household's hair gets stronger over time, not just smoother for a day.
The Science of Bond Repair.
Every time you color, heat-style, or wash in hard water, the bonds that keep hair strong start breaking — that's what causes breakage, dullness, and frizz. Olaplex's patented bond-building technology targets those broken bonds and relinks them from the inside out. No.4 and No.5 are the daily duo that maintains that repair between washes, so your hair keeps getting stronger instead of more damaged.

Breakage, dullness, split ends, and frizz are the late warning signs.
What you can expect with consistent use of the Olaplex No.4 + No.5 bond-repair duo.
From the very first washes, hair feels noticeably softer and easier to detangle. Frizz starts to settle and your hair looks healthier and shinier.
Strands feel stronger and you notice less hair snapping when you brush or style. Split ends look less obvious and hair holds together better.
With bonds being rebuilt wash after wash, hair looks shinier, feels stronger, and is far more manageable. Damage stops compounding.
Consistent use means stronger, smoother, salon-quality hair that handles coloring, heat, and daily styling far better than before.
