Highlights and SwimmingQ: After getting my hair highlighted blonde, how long should I wait before swimming in a chlorinated pool?
A: While I don't advise jumping into the pool immediately following the highlighting service, the amount of time you need to wait depends on the condition of your hair following the service. After a hair color or highlighting service, the hair is usually conditioned to help seal the cuticle layer. This helps to prevent fading and lock in moisture to keep the hair from becoming dry and brittle.
If your hair is in good condition following the highlighting, you should be fine to go swimming. Just remember to rinse the hair with fresh water and condition the hair after you come out of the pool. You can also visit your local beauty supply store and look for "anti-chlorine" shampoos and conditioners that will help to remove the chlorine from your hair after swimming.
Keep an eye on your hair if you swim frequently, to make sure you can avoid any adverse effects to the highlights, and to head off any possible damage to your hair. In addition, look for a leave-in conditioner with a sunscreen, since the highlighted hair can be susceptible to bleaching in the sun and could cause you to have lighter highlights than you intended with prolonged exposure.
