Does keratin extensions damage your hair?

“Keratin hair extensions can potentially damage your hair,” Hazan says. “Particularly if you leave them in for too long of a stretch of time, and if you never let your hair breathe and grow without the heavy weight of long extensions.” They typically last around 3–5 months, depending on how well you take care of them.

Can you swim with keratin extensions?

It’s OK to go swimming, of course, but don’t allow extensions to soak in water for too long, and dry them as soon as you get out of the pool or ocean. Arussi recommends rough-drying the bonded areas every time they get wet to help extensions last longer. You can let the rest of the hair air-dry.
