Overview

Conditioning with this formula coats the cuticle in Biomimetic lipids that restore the natural lipid layer and form a water-repelling barrier against humidity. Protein actives work inside the strand for strength, and the formula is free of silicones.

Frizz control without weight is the case, using a lipid-mimicking ingredient in place of silicones to smooth the surface. The longest humidity claims apply to the shampoo and conditioner used together, so the conditioner alone may fall short of them.

Who it's for

People whose hair puffs up in humidity and who avoid silicones fit this conditioner. Those wanting a rich fragrance should look elsewhere, as it is unscented.

Pros and cons

Pros
  • Silicone free smoothing
  • Lightweight, no weigh-down claim
  • Protein actives for strength
  • Adds shine by sealing the cuticle
Cons
  • Top humidity claims need the matching shampoo
  • Hair type listed only as normal

Performance notes

Frizz starts when a damaged cuticle lets water swell the fiber. The conditioner lays down a lipid-like layer that repels water and seals the cuticle, so hair stays smoother as humidity rises, while protein actives add internal strength.
