Throughout our history – societally speaking – the common changes that occur in individuals as we age have been subject to very critical opinion. Our media-obsessed and advertising-saturated culture focuses on perceived
physical ideals of youth, slimness and esthetic perfection. These are standards that no one can live up to – not even the models presented to embody these ideals. And in all of this one particular issue comes to the forefront
for most people: hair loss.
Hair loss is an issue that affects most men and women. According to studies, 35 percent of men will experience noticeable hair loss some hair loss by the age of 35, and 60 percent of women will have noticeable hair loss by
the age of 65. The common cause of this is a condition called androgenic alopecia. It is predominantly a genetic trait and can be exacerbated by other physical, health and environmental factors.
Such hair loss is not universally seen. Androgenic Alopecia is most common among Caucasian men. Next in line for the condition are those of Asian extract, followed by African Americans. Persons of Native American descent (as
well as Eskimos) have the lowest rate of occurrence for androgenic alopecia. And while women aren’t quite as commonly affected by this condition, some 13 percent of pre-menopausal women have shown evidence of the condition,
and as many as 75 percent of women over 65 show signs of it.
Until very recently (historically speaking) the only options for dealing with the hair loss caused by androgenic alopecia were acceptance or concealment. Men and women who suffered such hair loss were forced to either
come to terms with going bald, or find some way to hide the loss of hair. This led to some unfortunate looks for some people. Bad comb-overs and fake-looking toupees topped the list of the greatest offenses.
Then around 30 years ago, a drug that was being used to treat high blood pressure was found to cause new growth of hair in men with androgenic alopecia. It eventually began being used for this secondary ability as a primary
treatment. It was applied topically and gave good success to many individuals.
A few decades later, a drug being used for the treatment of enlarged prostate in men, was seen to have a similar result in regrowing hair in men
with androgenic alopecia. In 1997, the U.S. Food and Drug Administration approved the drug for the treatment of androgenic alopecia. This drug, called finasteride, gained popularity because it was an oral medication and had
greater ease of use therefore.
The greatest problem with these treatments is the fact that they are long-term and must be continued indefinitely to maintain the results you achieve. If the medications are discontinued, the benefits gained will go away
within six to twelve months. And in the case of finasteride, there has been no evidence that it has any benefit to women regarding hair loss. In fact, women are discouraged from handling finasteride, particularly if they
are or plan to become pregnant as the drug can be absorbed through the skin and can cause defects in male fetuses.
A secondary issue is that the use of finasteride has different levels of effectiveness for different male individuals. And some men may undertake the expense of long-term treatment and maintenance only to find they get no
benefit from the drug.
In spite of these ominous warnings, finasteride has seen increased popularity as a hair loss treatment. Advances in genetic testing have enabled scientists to devise a test to determine the likelihood of androgenic alopecia
in individuals (both men and women). And further studies have led to the development of genetic testing to determine how well finasteride will work for an individual.
The hair loss test, known as HairDX test has allowed individuals to get an idea of how likely they are to experience hair loss as they get older, and how extensive that hair loss could be. While granting some individuals
peace of mind concerning the future of their hair, it allows others who aren’t so lucky to know what to expect and enables them to make an informed decision on how soon to begin treatments (if desired) to gain maximum
benefit. The test for genetic hair loss works for both men and women, even if the treatment options for women are more limited.
For men, the HairDX test for Male Pattern Hair Loss reports on the presence or absence of a specific variation of the gene that governs androgenic alopecia. A positive test result indicates that there is a high risk of
genetic hair loss. Men who test positive have approximately a 70% chance of going bald, while a negative result indicates that there is approximately a 70% chance of keeping the hair.
For women, the test offers a score (called the CAG score) which indicates the likelihood of hair loss. The lower test scores are associated with higher risks for significant hair loss, while the higher CAG scores indicate
that there is a lower risk of losing the hair. Studies have shown that only 2.3% of women with a CAG score below 15 did NOT develop hair loss.
