A lightweight bond-building conditioner that detangles fine hair without flattening it
OLAPLEX Nº5 Fine Bond Maintenance Conditioner is a lightweight conditioner for fine hair that wants hydration and long-lasting volume. It contains OLAPLEX's patented bond-building technology (bis-aminopropyl diglycol dimaleate) to strengthen the hair fibre and protect it from daily stress. Flexible polymers help give lift, low molecular weight hyaluronic acid adds softness without coating the strands, and a Hydra-Balancing Matrix keeps the formula weightless. Hair detangles easily, stays airy and looks fuller and healthier over time. It is vegan and safe for colour-treated hair.
The texture
A light cream conditioner that spreads easily from mid-lengths to ends and rinses out quickly with no heavy residue. Pleasant fruity scent.
Who it suits
- Fine or flat hair that lacks body
- Fine hair damaged by colour, bleach or heat
- People who find classic conditioners too heavy
- Daily or frequent washing
Worth knowing before you buy: The formula contains fragrance. On very dry or thick hair it may not be rich enough; the regular Nº5 is better there. Nº3 used once a week before shampooing boosts the repair.
How long one bottle lasts
Used three or four times a week, the 100ml bottle lasts about four to six weeks. Good as a travel size.
