The Overall Winner

Brazilian Blowout Daily Smoothing Serum (Brazilian Blowout)

It's a clash of titans developed by the same salon pioneers. Brazilian Blowout Daily Smoothing Serum edges out the overall win for coarse, curly hair needing heavy-duty 85% humidity blocking and daily cuticle smoothing. However, Leaf & Flower CBD 7-Minute Blowout is the superior choice for fine to medium or bleached hair where cutting blow-dry time in half and mending damaged split ends is the primary priority.
