Q: Do elastic hair bands damage hair?
A: Damage usually comes from bands with a metal join or from wearing one at the same tension in the same spot all day. A band with no metal fastening has no join to catch or snag.
Q: How often should you replace hair elastics?
A: Once a band has stretched and no longer springs back it needs pulling tighter to hold, which is when it starts causing tension. Replace them rather than doubling them up.
Q: Do elastic hair bands work on thick hair?
A: Yes. The stretch means one or two will hold most thicknesses without digging in, and with no metal crimp there is nothing to press against the hair.
