Q: Is BioBrew™ Fermented Strengthening Serum a leave-in conditioner?
A: BioBrew™ Fermented Strengthening Serum is similar to a leave-in conditioner because it contains lightweight oils that provide hydration. However, if you want to use a traditional leave-in conditioner that provides even more hydration, we suggest applying BioBrew first since it is thin before layering on a second leave-in conditioner.
