You're Sweating — Everywhere
You can use your antiperspirant to control sweating in unusual areas, like between your boobs and thighs, says Dr. Audrey Kunin. She recommends using an aerosol version, which is less sticky than a roll-on or solid and won't look chalky on your skin.

The Sun Is Frying Your Hair
"The longer your hair, the more you need to treat it with special care or it can get strawlike," says celebrity hairstylist Ken Paves. Use a moisturizing shampoo and conditioner (on ends only) every other day. Rinse with water alone on off days. Avoid heat-styling (blow-drying, flat-ironing) as often as possible, but if you must, prep hair with a protective spray, such as Frédéric Fekkai Coiff Defense Pre-Style Thermal/UV Protectant, first.
Another tip: When you're at the beach, spread some of the sunscreen you use on your body through your hair so that it doesn't dry out and get crispy.

Deal with Dandruff
Even if your flakes aren't caused by dandruff (some skin conditions like seborrheic dermatitis can also result in scaly scalps), you can use a dandruff-reducing shampoo with ingredients, like zinc pyrithione (which reduces fungus) or selenium sulfide (which slows cell turnover) to prevent additional shedding. Use the shampoo at least once a week if you want to be wear dark tops with peace of mind.

Your Back Is Breaking Out
The upper back is full of oil glands, making it a prime spot for breakouts, says California-based dermatologist David Sire, M.D. Since perspiration is a main cause of clogged pores, it's not unusual to see more back acne during the hot summer months. Before bed, apply a benzoyl peroxide product directly on the pimples to dry them out and kill bacteria. Try: Clean & Clear Persa Gel 10.
To keep pores clear, wash your back in the shower with a body wash containing salicylic acid, like Neutrogena Oil-Free Acne Body Wash Pink Grapefruit or Murad Acne Body Wash, $39.50; ulta.com

You're Prone to Ingrown Hairs
To avoid unsightly razor burn, hydrate thirsty skin with a shave cream rich in essential oils, or forgo the blade altogether and use a shea-butter-infused depilating cream. New spray-on formulas mean hands stay clean, but apply more than you think you need to and stand on a towel to keep bathroom tiles slip-free. For a quick fix on the go, toss a mini electric shaver in your beach bag great for showerless fuzz-busting but remember to lube up afterward (those metal teeth are moisture-killers).

Your Armpit Skin Is Darker Than the Rest of Your Skin
Shaving and rubbing against rough fabrics create friction, and that leads to inflammation and brown or grayish patches, says Jeanine Downie, a New Jersey dermatologist. Brighten up with a lotion that contains hydroquinone (a good one: Ambi Fade Cream, $5; walgreens.com). Also, use a new razor every three shaves (dull ones irritate your pits).
Your Sunscreen Makes You Break Out
"Usually acne caused by sunscreens is not from the chemicals that provide the sun protection, but secondary to the vehicle in the sunscreen," says NYC-based dermatologist Eric Schweiger. "Try to find oil-free or non-comedogenic sunscreens."

Yellow Pit Stains Are Ruining Your White Tank Tops
"Aluminum-based antiperspirants are acidic and contain compounds that can contribute to staining," says Schweiger. "In addition, sweat has trace amounts of urea (also found in urine) and this can contribute to the dying of fabrics. If the yellow stains are really bothering you try stop using antiperspirants, and stick with deodorants that have no aluminum chloride in them. These serve only to mask the odor and not to reduce sweat production like an antiperspirant. Deodorants will thus help you with your shirts but not with your sweat!
