4. Crimped hair

Everyone from Christina Aguilera to Britney Spears rocked crimped hair, which was the terrible lovechild between straightened and curly hair. A crimping iron helped you achieve tight, zig-zag waves. People wore it in sections, which wasn’t that bad, but as an all-over look, it was way too much.

5. Liberty spikes

This trend involved applying gel to short—to medium-length hair until it formed stiff, vertical spikes. Back in the day, it was very punk and rock n’ roll, but is it worth it to ruin your hair with so much product? Plus, it looked very messy when it started to sag and needed a touch-up.

Although a revamped version of the butterfly clip style is making a comeback, in the 1990s, it was often combined with badly done highlights and used way too liberally, with an overload of tiny clips pulling back random sections for a busy, mismatched look.
