You may have seen the ads in the back of men's magazines, you've heard the commercials on the radio, and you've seen the infomercials promoting miracle treatments for hair loss. The bottom line is that most advertised "treatments" do not work for the prevention and treatment of hair loss. If a hair loss treatment is not approved by the FDA or recommended by the American Hair Loss Association, chances are you are wasting your time and money.

With those pinned down, it wasn’t hard to determine which don’t actually work. Pretty much all the “active” ingredients listed in ineffective treatments — from biotin and zinc to emu oil and saw palmetto — have never been proven, and are instead marketed based on logical-seeming correlations. It would make sense that biotin, a B vitamin readily found in hair, skin, and nails, could help hair grow more quickly. And caffeine is a stimulant that works in coffee, so rubbing some on your scalp might wake some of those sleepy follicles… right?

"Despite some of the claims, a shampoo or conditioner won’t be able to stop or slow hair loss, nor help with a receding hairline or thicken hair that’s becoming thinner," says trichologist Anabel Kingsley from The Philip Kingsley Trichology Clinic in London. "At best, a thickening shampoo will make hair temporarily thicker for a short period of time, but they certainly won’t help with hair loss or thinning."
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
