Key Ingredients
VITAMIN E
Protects bleached hair.
Renowned for its anti-oxidant properties.
It is capable of neutralizing oxidative
molecules by binding to them to help
protect hair from external aggressions.
CAMELLIA OIL
Nourishes dry hair.
Camellia oil is mainly composed of oleic acid
omega-9 (82% of its composition), and linoleic
acid (around 12%).
This oil boosts suppleness and gives lasting
radiance to the hair fiber with intense
nourishment.
POLYPEPTIDE
Fights humidity-induced frizz.
Peptides have the ability to target the
weakened part of the fiber.
They smooth the damaged part of the surface
and protect it against the variations of humidity
and the appearance of frizz.
LACTIC ACID
Resurfaces & illuminates dull,
color-treated hair.
Known for its chelating properties, it can
“trap” dulling minerals (such as calcium)
that can compromise hair shine.
It has also the ability to help the
deposition of the caring agent of the
formula (pro-deposition) on the damaged
part of the fiber
PROTEIN
Repairs damaged hair.
This vegetal protein have the ability to
target the most damaged part of the fiber
thanks to electrostatic interactions.
Once close to the damaged part of hair,
it can smooth the surface, and acts like a
bandage to repair the most damaged
areas of hair.
