MYRTLE BEACH (WPDE) -- Cars, electronics, and haircuts all top the list of things your might not have budgeted to pay for this summer, but might need to.

Scot Collins is a hairdresser at Dulce Lusso Salon in Market Common. He says while it's a bit of an urban legend that your hair grows more in hot weather, the temperature may have a bit of an indirect role in hair growth.

"It's more linked to metabolism. People are more active in the summer, and the increased activity will increase you metabolism, and that makes your hair, your skin, your nails all grow faster."

Collins also adds that for his clients who get their hair colored, the summer heat, humidity, and sunlight could land them back in his chair quicker. "Artificially colored hair fades faster than naturally pigmented hair. "

He recommends products with SPF in them for people to spray on their hair instead of spending money on the extra color. Those products online can cost approximately $20, compared to $60 or more for a trip to the salon.

The heat can also take a toll on your new cell phone battery. Randell Jennings, a manager with Batteries Plus in Myrtle Beach says the average cell phone and laptop batteries last 2-3 years. In the South Carolina summer, he says that's cut in half.

"Not necessarily having it out walking around in the heat today, but leaving it in the car that's 120, 130 degrees just kills the battery."

Speaking of your hot car, the way the heat affects the air you put in your tires could also mean the difference between a quarter at the gas station air pump, and several hundred for a tow and the cost of replacing a flat.

Gordon Spencer, service manager at Mason's Tire, says the air pressure in your tires is affected by both the friction caused by driving on them as well as the hot temperatures outside. The air in your tires can expand causing a blowout. He suggests when filling your tires with air, check the maximum tire air pressure number listed on the inside of your car door, rather than the number listed on the tire, which is usually much higher.

Blasting your car's air conditioning on high could cost you hundreds in repairs over time and wears on the car's performance. Spencer says there's a cheaper, "right way" to cool down your vehicle.

"It's 90 degrees outside, and it's like 115 inside the cab of your vehicle. [When you] start your car, put your air conditioning on, set it to outside air. Not max, not [recirculation]," he says.
