Straw hats have always been a popular choice for beach-goers, but the styles today are much more fashionable than ever. Right now, the hottest hat is a straw cowboy-style hat. The issue with any kind of straw hat is that the sun can get through, so if you're worried about chemically-treated hair becoming dry or color-treated hair changing color, you may want to apply a protective product underneath or even wear a scarf underneath the hat to ensure no sun exposure.
Minimize your hair's exposure to the sun between 10 a.m. and 3 p.m. when the rays are the most potent. If you must be out during those times, wear a cover-up to shield your strands from sun exposure.
Don't assume that all hair care products contain SPF agents. Although many brands have some level of sun protection, not all products contain agents like octyl methoxycinnamate. The potency may vary greatly. Since SPF formulas can make products heavy or oily, products may only contain a maximum SPF level of 10.
