I'm a guy with fairly long, receding hair (yes!, I do the Italian comb-over -- it's vanity, ya know!), and I've been using the Goody latex (I assume) elastics. They work very well for me. They start out about an inch from end to end, and end up about three inches long from end to end, before I discard them. However, I haven't been able to find any (at Shopper's Drug Mart or Walmart in Canada), so I bought a similar brand. Put one in my hair the first morning and it was gone a while latere. Did the same thing the nextday, with the same results. Luckily, I still had one of the stretched ones and am currently using it, while I await a (hopefully) new shipment to come in. PLEASE, PLEASE, PLEASE, Don't discontinue these!
