In our May 2011 "A Smarter Shampoo" Get Gorgeous section opener, hairstylist River Lloyd of the John Frieda Salon in New York City explains that the chlorine and chemicals in your shower water may be hurting your hair—but that a shower filter can remedy the problem. Here, three tell-tale signs that your shower water may be damaging your strands:
1. Your hair "steams" when it's heated under a blowdryer.
2. When it's damp, your hair has a slight "wet-dog" smell to it.
3. Even after a proper blowout, your hair still feels tangled.
Do any of these sound familiar? If so, you may want to consider attaching a shower filter to your showerhead: They remove up to 91 percent of chlorine, leaving your strands softer, smoother, and more manageable, and keeping your color truer longer, Lloyd says.
