KeraGuard is described by the ingredients player as ‘powerful protection and repair for hair’, and offers a mix of tara tannins and organic sunflower sprout extract to carry out the following:
Protects hair against heat and UV stress
Repairs chemically treated hair
Prevents color fading of hair
Restores the resilience of hair
In comprehensive ex-vivo studies KeraGuard was shown to repair chemically treated hair and to protect hair against physical stresses, Mibelle says.
On top of this, 0.5% KeraGuard was shown to protect dyed hair from color fading as well as to reduce the damaging effect of heat on the hair cuticle scales. It performs effectively in leave-on and rinse-off formulations.
Why tara tannins?
According to Mibelle, tara tannins are extremely potent antioxidants and radical scavengers that naturally bind to the protein structure of the hair.
In combination with the compounds of the sunflower sprouts, they are capable of neutralizing negative daily effects on the hair, the ingredients player suggests.
“Hair is constantly exposed to a variety of stress factors,” Mibelle explains. “There is physical stress, such as blow drying as well as environmental stress factors like ROS, UV and pollution.
“In addition, there is chemical stress, which includes coloring and straightening. All of these different factors induce structural damage to the F-layer, the outermost protective layer of the hair, as well as to the hair fiber.
“As a result, the hair becomes more porous, brittle, dull looking and is actually even more exposed to further damage.
“KeraGuard helps to repair the hair and make it healthy and lustrous,” Mibelle asserts.
