Self-tanners: Are they safe?
Sunless tanning products, also called self-tanners, can give your skin a tanned look without exposing you to harmful ultraviolet (UV) rays. The active ingredient in most sunless tanners is the color additive dihydroxyacetone (DHA). DHA reacts with dead cells in the skin's surface layer to temporarily darken your skin. The coloring gradually fades within a few days. Caution: Most self-tanners don't contain sunscreen. If you spend time outdoors, sunscreen is essential.
Applying sunscreen? Don't be stingy
Most people use sunscreen too sparingly. If you use sunscreen generously and frequently, a bottle of sunscreen shouldn't last long. Generally, a liberal application is 1 ounce (30 milliliters) — the amount in a shot glass — to cover exposed parts of the body. You might need to apply more, depending on your body size. If you have a 4-ounce (118-milliliter) bottle, you'll use about one-fourth of it during one application.
Sunscreen: One dose doesn't do it
You can't put on sunscreen in the morning and expect to be protected for a full day in the sun. To maximize sun protection, apply generous amounts of sunscreen to dry skin 15 minutes before you go outdoors. Reapply sunscreen every two hours — or more often if you're swimming or sweating.
Sunscreen shopping tips
When you're shopping for sunscreen brand matters less than how you use the product. Look for water-resistant, broad-spectrum coverage with an SPF of at least 30. Check the sunscreen's expiration date. Also, find a sunscreen you like. If you don't care for the sunscreen, you're not as likely to use it consistently.
Is stress to blame for hair loss?
Stress and hair loss can be related. Extreme stress could take a toll on your tresses. But any hair loss may be temporary. Be sure to talk to your doctor if you notice sudden or patchy hair loss or more than usual hair loss when combing or washing your hair.
Sunless tanning tips
Want to avoid orange palms, knees and elbows when you're using sunless tanning products? Before applying a sunless tanning product use a washcloth to exfoliate, especially in areas with thick skin such as your knees and elbows. This will help remove excess dead skin cells. Apply the tanner to your body in sections. Wash your hands with soap after each section to avoid discoloring your palms. Knees, elbows and ankles tend to absorb more of sunless tanning products. To dilute the tanning effect in these areas, gently rub them with a damp towel.
Don't believe shaving myths
Contrary to popular belief, shaving hair doesn't make it grow back thicker. And shaving doesn't affect how dark your hair is or how fast it grows. Shaving facial or body hair gives the hair a blunt tip that can feel coarse as the hair grows out. During this phase, the hair might appear darker or thicker, but it's not.
