Nail Dehydrator, Explained
Quick definition
A prep liquid stripping oils from the nail plate so products grip properly.
Dehydrators remove the invisible lipid layer that makes polish lift. Applied after shaping and before primer/base, they double adhesion — especially on oily nail plates.
Skip it and even premium gel can bubble or peel within days; it costs under $10 and solves most mystery-chipping complaints.
