Can salt water ruin a new perm?

Yes, salt water can potentially ruin a new perm. The high salinity can strip moisture from the hair, leading to dryness and frizz, which can cause the curls to lose their shape and definition. It's advisable to rinse hair with fresh water after swimming in the ocean and use a good conditioner to help maintain the perm's integrity. Additionally, using a protective hair product before exposure to salt water can help minimize damage.
