Overview

Morpho-keratin and lipids do the smoothing in Kerastase Discipline Fondant Fluidealiste, coating each hair fiber to tame frizz. A small amount is worked into wet mid-lengths and ends after shampoo, left briefly, then rinsed.

Controlling frizz while keeping hair light and moving is the argument, so it suits fine but unruly hair that heavy conditioners flatten. Bottle size is missing from the listing, which makes comparing salon conditioners harder.

Who it's for

People whose hair puffs up and loses shape, especially fine or dry hair that wants softness and shine. Those needing heavy moisture for very coarse curls may want a richer mask.

Pros and cons

Pros
  • Smooths frizz without heaviness
  • Adds softness and shine
  • Short leave-on time
  • Part of a full Discipline routine
Cons
  • Bottle size not listed
  • Designed around the matching shampoo
  • Scent not described

Performance notes

Smoothing comes from morpho-keratin and lipids coating the fiber, which flattens the cuticle so hair reflects light and resists humidity. Keeping it on mid-lengths and ends avoids weighing down the roots. Pairing with a heat protectant before blow-drying extends the smooth finish.
