Wherever you look, you are guaranteed sight of an ad for a weight loss product or service. It can be a careful pitch from a local aerobics class or an over-the-top claim for a “natural” product that you can eat as much as you like and still lose weight. This evidences a sad truth. As millions of us grow steadily more overweight, there are thousands of companies and tens of thousands of products and services that target us. The intention is to exploit our fears and insecurities, and so extract the maximum amount of dollars from us. This business is worth billions every year and, truth be told, the first thing that gets lost in the marketing is the truth. Although the FDA has a specific department tasked with policing the advertizing of all weight-loss products, it has been consistently underfunded and is completely unable to stay on top of the flood of ads that compete for our attention. Similarly, the majority of states have “false claims” laws that allow action to be taken against any seller or service provider exaggerating the quality, effectiveness or value of their product or service. But states are often reluctant to interfere in the “free market” and leave it to individuals to claim they have been cheated by the companies. Read the rest of this entry »

One of the most commonly suggested causes of hair loss in both men and women is a genetic defect. The fact it may be inherited means it is not your fault when your hair thins and falls out and, perhaps more importantly, the condition is not necessarily something that can be cured. Of course, there is some evidence that hair loss does run in families, but there is more evidence that our lifestyles and medical decisions can be even more important factors in deciding who loses hair and how quickly. We will ignore the cultural effect of changing hairstyles where too much traction in pulling the hair back into a ponytail or comparable style may accelerate hair loss, the effect of a general anesthetic for surgery, increased levels of anxiety and stress, and both chemo- and radiotherapy for cancer. The most consistent cause surrounds the level of different hormones in the body.

In women, for example, the level of estrogen drops during and after pregnancy, and during the menopause. This has been directly linked to both the thinning of hair and its loss from the scalp. Some women also lose hair as a reaction to particular oral contraceptives. For obvious reasons, the level of hormones naturally occurring in the male body tends to be more stable. But, in both genders, thyroid problems can affect the production of hormones and produce early baldness in men. Similarly, for a number of reasons, the levels of the hormones may be affected artificially. The most consistent causes stem from the use of steroids which are commonly used for a variety of strictly medical, e.g. to control asthma, and other purposes, e.g. as supplements to promote growth and for strength while weight training. As an adverse side effect, many weight loss products affect the thyroid and hair suffers. Finally, it is not just athletes who discover some diet and other supplements affect the level of testosterone in their bodies. Many who take “natural” dietary and nutritional supplements find out the hard way that some “natural” chemicals affect hair growth and retention. Read the rest of this entry »
