Vitamin C shower filter claims to eliminate dandruff, frizz, and eczema Flu season's favored antidote - Vitamin C - is now being taken out of the vitamin capsule and into the shower - but not to ward off sickness. By reducing water's chlorine content, Vitamin C filters - which can be purchased online for between $35 and $125 - are said to leave the hair and skin in better condition. The devices are said to neutralize, and therefore reduce chlorine's residual side effects like dry skin, dandruff, frizzy hair, headaches, and itchy eyes, researchers say. They can even help subside eczema. Vitamin C Showers: A new bathroom trend says Vitamin C showerheads are a cure for dry skin and hair Much like its use in pool maintenance, chlorine is typically deployed into public water supplies to disinfect the water as it travels through pipelines. While the chlorine loses its purpose once it reaches your tap, it can still leave behind the aforementioned reactions. Vitamin C has been deemed as a foil to these side effects. Vitamin C "eats" or consumes the chlorine, and has been promoted by the U.S. Department of Agriculture as a proven chlorine neutralizer. Chlorine filtering devices loaded with Vitamin C are already being installed in luxury hotels and condominium buildings in cities across the U.S. The MGM Grand in Las Vegas says that Vitamin C shower filters are a key tool in "promoting healthy hair [and] skin." The hotel has installed the filters in its "Stay Well" rooms. The filters are popping up in luxury apartments too. Leonardo DiCaprio is reportedly moving into a New York City "health-centric" condominium complex where the showers come furnished with Vitamin C filters. The devices, some of which are offered as complete filtering showerheads, and others as screw-on showerhead attachments, each come with refillable cartridges that last somewhere between one and three months. But do they work? Online reviewers seem to offer a range of opinions - making the filters" effectiveness seem unclear. For the home: Sonaki's Lotus showerhead costs approximately $95 and uses refillable cartridges to help neutralize chlorine The standby: Vitashower's SF 1 filter costs approximately $25 on Amazon Apartment Therapy writes: "During my shower, there wasn't the usual chlorine smell I'd become accustomed to, and the very first time I washed my hair in the filtered water it was noticeably softer and less frizzy." However, the website noted: "I was hoping that the filter would be a cure-all and it definitely wasn't. I will say, I was hoping that the longer I used it, the better the results would be, but that wasn't the case. I found that the improvement I experienced the first time was the best it ever got. Amazon reviews of the Vitashower SF-1 filter, a more popular style, were more positive. Reponses ranged from "My skin cleared up completely after using this for about a week," to, "gone is the dry, lifeless, body-less frizzy hair and dry skin. I had just assumed it was my diet or something that was causing the problem. It was my WATER. But Neal Langerman, an officer for the American Chemical Society's Division of Chemical Health and Safety told Bloomberg Businessweek that the filters are not as purposeful as they may seem. "First off, chlorine and chloramines do not cross the skin barrier, nor does vitamin C ... [Also] I don't think the reaction would be complete - the neutralization, if you will - by the time the water hits your head or flows down the drain," he said Langerman added that, "there are much, much better ways to spend your money, more healthy ways to spend your money."
