Mibelle Biochemistry presents KeraGuard for hair repair and protection


KeraGuard combines tara tannins derived from Caesalpinia spinosa pods and organic sunflower sprout extract.

This unique combination is revealed as a powerful antioxidant elixir for hair care applications.

Although hair is a physiological phenomenon, it is also a social one. Indeed, hair is an object of intense elaboration and preoccupation in almost all societies.

Hairstyles and rituals surrounding hair care and adornment tend to convey powerful messages about the beliefs, lifestyles and commitments of a person. Therefore, our hair is regularly subjected to weathering.

Hair weathering is the deterioration of the hair shaft from root to tip and is the result of a range of cosmetic and environmental factors.

Cosmetic practices such as combing, brushing, straightening, perming, dyeing, etc., as well as environmental factors such as exposure to UV light and polluted air (significant amounts of free-radical molecules) can induce structural damage to the F-layer and the hair fibre.

The cuticle becomes raised and porous, which exposes the cortex to further damage. A decrease in hair shine, colour, elasticity and strength is observed, which ultimately leads to hair damage.

In different studies measured utilising state-of-the-art technologies, KeraGuard revealed a capacity to protect hair against free radicals and physical stresses.

It was also shown to protect dyed hair from colour fading as well as to repair chemically treated hair. In plus, KeraGuard showed a protective effect from heat damage.

Formulating with KeraGuard

  • Recommended use level: 0.5% – 2%
  • Incorporation: For cold processes, dissolve KeraGuard into the aqueous phase. In hot / cold
 processes, add during the cooling phase below 40 °C
  • Thermostability: Temperatures of up to 40 °C for a short time will not affect the stability of KeraGuard.
