Making simple change to how you wash your hair will leave it looking ‘really shiny

No matter your current hairstyle or texture, everyone’s after that ‘shiny and beautiful’ mane. But nailing the perfect hair care routine can be a tricky business, and sometimes our efforts can leave it looking limp and dull instead. A hair expert has revealed how the temperature of the water you use on wash day could be a game-changer. Hair health whizz @alexiszander_ hopped onto TikTok to explain “the science behind washing your hair with cold water”. “Have you heard that you should wash your hair in cold water?” she posed to her followers. She said the logic behind opting for a chilly rinse is pretty straightforward, reassuring viewers not to fret – stick to her tips and you’re on track for luscious locks. “When heat comes in contact with your hair, it actually opens up your cuticle,” she divulged. “This is why sometimes when we do hair treatments, we use heat. It opens up the cuticle, so when we’re doing a chemical or condition treatment, it will further penetrate and get inside that hair strand”. Then she explained cold water is best for rinsing your tresses as it does the exact “opposite” of what hot water does, meaning it seals the cuticle tight. “So, if you end your shower with cold water, this will cause the cuticle to close, and when everything is flat, the light can reflect off of your hair,” Allie revealed. Wrapping up her viral video, she explained that this simple trick is the secret to achieving “really shiny and beautiful” hair. In the comments section, people were quick to express their gratitude for the tip, with some saying they’re off “to shower right now” to give it a whirl. Another joked: “There’s no hot water in my house at the moment I have no choice but to use cold water.”
