If you have any women in the house, hair ties are WAY more plentiful, lol.  I usually find them near the shower, or on the bedroom doorknob.  I've use rubber bands, but after about a week in the sun, they are done.  A nice hairband will last you a season or more.

I’ve been using the same rubber bands for over a year now without complaint. Daughters have been out of the house for some time and my wife rarely uses a hair tie. So, left to my own resourcefulness .... https://www.officesupply.com/office-supplies/general-supplies/clips-tacks-rubber-bands/rubber-bands/universal-rubber-bands-size-gauge-beige-pack/p47593.html?ref=pla&utm_source=google&utm_medium=cpc&adpos=&scid=scplp47593&sc_intid=47593&gclid=EAIaIQobChMI1YfnkYPk6wIV6xatBh202QjQEAQYASABEgKJtfD_BwE
