Overview
Not a rinse-out conditioner, the BioSilk leave-in stays in damp hair to condition, smooth frizz and guard against heat styling. Hydrolyzed silk and panthenol strengthen strands with a light, non-greasy feel.
One bottle covers detangling, curl definition, color protection and thermal protection, which simplifies a routine. The feel stays light on most hair. Severe damage needs a deeper treatment alongside it.
Who it's for
Daily stylers who want one product before the dryer suit the multitasking formula. Those with extreme breakage should pair it with a dedicated repair treatment.
Pros and cons
- Heat protection for hot tools
- Light, non-greasy feel
- Defines curls and adds volume
- Helps protect color from fading
- Light formula for severe damage
- Fragrance listed only as Fresh
Performance notes
Silk protein coats the cuticle to smooth it and cut frizz, while panthenol holds moisture. Applying to damp hair before heat lets it act as a thermal barrier. Overuse on fine hair can flatten volume.
