Q. I have terrible dandruff that just doesn't seem to ever clear up. What can I do to treat it?

A. For most people, using a dandruff shampoo once or twice a week can control this annoying condition, in which the skin on the scalp becomes dry and flakes off. But in some cases, the condition doesn't clear up and actually requires medical attention.

Eczema is an itchy rash that's often hard to get rid of. Most people can't help scratching it, which further irritates the skin. Eczema is often, but not always, related to allergies. A common cause is your skin overreacting to everyday irritants, such as dust, soaps and detergents, or even dry, cold air, which triggers an intensely itchy allergic reaction.

Skin affected by eczema becomes dehydrated and dry easily, so treatment involves rehydrating the skin. Baths and showers must be short and not too hot. Afterwards, gently pat your skin dry and promptly apply moisturizers while your skin is still moist. Thick creams that lock in the moisture help the most. Be sure to choose creams or lotions without fragrances or preservatives. Limit the use of soaps and shampoos, too. These products remove the skin's natural oils and worsen dryness. And over-the-counter oral antihistamines can help with the ferocious itch.

A widely-advertised facial moisturizer claims to be the best on the market — and sells for $225 per bottle. Should you buy it? Another brand offers a complete skin care regimen — but it comes in 10 different bottles of lotions and potions that all need to be applied daily. Is it worth your time?

Despite manufacturers' claims, many cosmetic products will remove more cash from your wallet than dirt and oils from your skin. You don't need an expensive or lengthy skin care routine — and the good news is, the most effective and reliable regimen is also quick and inexpensive.

Using a CPAP machine is beneficial for people with obstructive sleep apnea, but if the machine isn’t kept clean it could lead to an illness. There are sanitizing systems available, but cleaning the parts by hand is just as effective.

PrEP (pre-exposure prophylaxis) is a daily medication taken to prevent HIV infection. While multiple studies show PrEP is effective, relatively few of those who might benefit are taking it. Will a 10-year initiative to reduce rates of HIV and a new formulation of PrEP help?

Approximately 1% of the population has vitiligo, a skin condition in which areas of skin lose their color. While topical treatments and light therapy help some, research with a class of medications not previously used for this condition has shown promising results.
