The national average price of gasoline this Labor Day weekend will be its lowest at this time of year since 2004, a result of low oil prices and a quiet hurricane season that has allowed refineries to churn out gasoline and diesel.
Many scalp problems such as hair loss, bumps, zits, dandruff and itchiness are caused by stress. According to Mountain Auburn Hospital, flaking, itching, pimples and crusting on the scalp are more often a result of either stress or a condition called lichen planus.
For example, how often you wash your hair can lead to the condition. Infrequent washing can cause a buildup of oil and skin cells and lead to dandruff flakes. Hair that's washed too often, on the other hand, can also lead to itchy scalp, because the oil that protects the scalp gets stripped away. Cold weather and the dry indoor air can also lead to a dry scalp [source: Mayo Clinic ]. Stress can affect dandruff, too. For instance, it can cause conditions like seborrheic dermatitis, which is characterized by an oily, waxy scalp and white or yellowish-brown flakes, to flare up [source: American Academy of Dermatology ]. One major contributor to itchy scalp is the skin condition called psoriasis.
