Overview
BioSilk Silk Therapy Lite is an ultra light leave-in that coats fine, thin hair with silk protein for a smooth, silky look. A small amount goes from mid lengths to ends on wet or dry hair, with no rinsing.
BioSilk gives fine hair the smoothness of a silk treatment without the oil that flattens it. It needs a good shake each time, and it adds polish rather than deep moisture.
Who it's for
Thin strands that turn greasy with heavier serums are the right match for this leave-in. Coarse or very dry hair may find it too light to make a difference.
Pros and cons
- Light enough for fine hair
- Works on wet or dry hair
- Silk protein smoothing
- No rinsing required
- Must shake before each use
- Too light for coarse hair
- Listed volume units conflict
Performance notes
Silk protein forms a thin film along the strand that reflects light and reduces friction, which reads as shine and smoothness. Applying only to mid lengths and ends avoids flat roots.
