BALDNESS CURES
Research using STEM CELLS from the follicles of your own locks transplanted into your scalp is under way. Scientists have already discovered that stem cells from adult mice implanted in the rodents can make fur grow back in bald patches, but human trials have yet to begin.

WRINKLE REPAIR
Doctors will HARVEST COLLAGEN from your face, grow it in quantity, and inject it into sunken or wrinkled areas to make them smooth. DNA-ALTERING pills or creams will instruct skin to produce more collagen or continue turning over cells to keep the complexion fresh.

COSMETIC DENTISTRY
Dentists may be able to take your DNA and use it to GROW BACK MISSING TEETH. Whitening will be lightning fast, and veneers will be superthin and strong. And some think braces and cavities may become obsolete.

HAIR
Topical GROWTH REGULATORS will speed or slow hair growth—meaning you can go longer between pricey trims. Other treatments will spur hair follicles to keep producing pigment instead of turning gray.

BREAST ENLARGEMENT
Instead of implants, physicians may use TISSUE ENGINEERING: They'll harvest the patient's own fat cells, which will be used to grow tissue that can then be inserted into the breast like an implant.

BODY WORK
Monitored by a doctor, HUMAN GROWTH HORMONE will be used to sculpt the body and combat muscle deterioration that accompanies aging. Handheld devices will use HIGH-FREQUENCY ULTRASOUND WAVES to break up fat (which can then be metabolized). And MAGNETIC BRAIN STIMULATION will transform offensive body odors into the pleasing scent of your choice.

FACE
RADIO-FREQUENCY WAVES will be used for mini lifts: By heating the subcutaneous collagen, they'll cause it to contract, eventually tightening the skin. BOTOX will be longer lasting, and lasers will zap acne by shrinking oil glands.

WEIGHT CONTROL
GASTRIC PACERS, which stimulate the stomach with electrical impulses to create a feeling of fullness, are being used in trials and could replace riskier gastric bypass. DRUGS, including those that block grehlin—a hormone that triggers hunger—will help quell the urge to eat.

That '70s GlOW
Back then, looking fab was tough

•SURGICAL LIFTS
Only stars had them. Others used devices like Face Up, a velour headband meant to pull facial skin up and back.

•SEEING PRETTY
Instead of specs, there were hard contacts so painful that 50 percent of wearers tossed them in the first year.

•CUTTING-EDGE WEIGHT-LOSS MEASURE
Having your jaw wired to keep your mouth shut.

•BREAST ENHANCEMENT
Silicone implants—not yet regulated by the FDA.

•NONSURGICAL ALTERNATIVE
The Mark Eden Bust Developer, an exercise gizmo supposed to add inches to the bustline. (From the same company: Vacu-Pants and the Sauna Belt Waistline Reducer.)
