The protection of hair against thermal damage by
Luviquat Sensation
3
The frequent blow drying of hair produces
- Cracks at the outermost cuticle cells -
Cuticle cell de-cementation and deformation
leading to cuticle cell lifting - This
produces the appearance of dullness in hair -
Increases degree of tangling in wet and dry hair

Methodology
Protection of hair cuticle cells against thermal
damage by Luviquat Sensation (LS)
Protocol

• - 25 cycles of wetting and blow drying were
  applied to
• single hair fibers ( 82 11 µm)
• - Each cycle consisted of 25 s immersion in a 1
  to 5
• shampoo dilution followed by 25 s of blow
  drying
• Shampoo 12 SLES, 3 CAPB Control No LS
• Shampoo sample with 0.25 LS

Conclusions

• The deposition of Luviquat Sensation to hair
  during shampooing
• provides smoothing and conditioning
• It also prevents the formation of steep
  de-swelling/contraction gradients
• across the cuticle cells during water
  evaporation by hair blow drying
• The overall effect is a substantial reduction in
  cuticle cell cracking
• and cuticle cell lifting by de-cementation
