The Truth About Sun-In Hair Product

With the hottest months on the horizon, many of us are looking into getting summer-ready, lighter locks. Whether just wanting a few golden highlights or going full-on blond, lightening your hair can put you in the right mood for all that summer has to offer. That being said, if you're planning on using Sun-In instead of hitting the salon, there are a few things you need to know before taking the plunge.

As per Bellatory, Sun-In is one of the most popular highlighting products out there. The easy-to-use spray is designed to be spritz-and-go, letting it work with sunlight or heat to naturally bleach the hair. It is very cost-effective at just around $5, which wouldn't even cover the tip at a professional salon! While all of that sounds amazing, the outlet asserts that Sun-In does not work for everyone and can cause "irreversible damage" to some.

Sun-In's bottle warns against using the hair product on dark hair, and for good reason. As Bellatory explains, Sun-In can leave permanent brassy, orange streaks on dark hair, and should only be used on blond to light-brown hair. The spray can irreversibly discolor dark hair, so if you're looking to go lighter for the warmer months, consider going to a professional hairstylist instead.

Others who should avoid Sun-In's natural bleaching? Anyone who has dyed their hair in the last six months. The chemicals in hair dye or other hair treatments can negatively react to Sun-In, possibly causing your strands to break right off. Ouch!

What to know before using Sun-In

Even if your hair is naturally on the lighter side and you've never dyed it, you should still consider avoiding Sun-In hair product if looking into dyeing your hair professionally in the future. As explained by Bellatory, Sun-In makes hair more unpredictable, so your stylist won't be able to know the final product of the dye process. Unless you want rainbow brights instead of buttery blond, you might want to consider avoiding the cult-classic spray.

Bevoir makes the case for Sun-In, though, saying the chemicals in the formula aren't necessarily worse for your hair than traditional bleach. While best for those with blond hair, the outlet also says that brunettes can eventually get their desired shade, but it will take quite a few tries to get there (which risks damage). According to Bevoir, the spray is completely permanent so it should be used with caution, and you should strictly avoid getting its chemicals on your face.

The hair professionals at Botox Capilar, meanwhile, says you should follow up Sun-In lightening with moisturizing hair masks, overnight coconut oil treatments, an extremely moisturizing shampoo and conditioner with coconut or argan oil, and to use any hot tools sparingly. Sun-In can be a great way to lighten hair naturally, but should be used with caution in order to get the golden, shiny results you're dreaming of.
