Government Study Finds Biotin Promotes Hair Growth in Women
How do vitamins improve aesthetics?
Both men and women suffer the woes of hair loss, but, because the condition usually starts earlier and progresses more rapidly in men, it has become more socially acceptable than the nearly inevitable hair loss in postmenopausal (and some younger) women. While many topical and oral preparations have been used in an effort to make hair regrow, thicken, and maintain or redevelop sheen, most of the substances have not been successful. Recently, however, biotin, a water-soluble vitamin and essential coenzyme, has been scientifically evaluated for its hair growth benefits in a government research study, and the results have been extremely promising.
Since hair loss in women, as in some men, can be damaging to self-esteem and even result in serious psychological problems, finding a method of improving hair growth is important medically as well as aesthetically. At Dedicated to Health Medical Group, our focus is on treating your body holistically, realizing that just as your physical well-being shows in your healthy appearance, improving your image of yourself can increase your self-confidence, making you more radiant and attractive.
How the Study Was Undertaken
To ensure that the research would provide reliable evidence, the NCBI (National Center for Biotechnology Information) established a double-blind, placebo-controlled protocol to test the effect of an oral biotin supplement to improve the condition of women with self-perceived thinning hair.
The participants in the study were healthy women aged 21 to 75 years with Fitzpatrick skin types I to IV (those typically used by dermatologists). These women were randomly divided into two groups, one that would receive the vitamin and one, which would receive a placebo. Placebos are used in such experiments to take into account the tendency of subjects to perceive success even when none exists. By using such a control group, the study becomes more accurate. This particular study was also “double-blind” because neither the patients nor the physicians knew which group was which and therefore neither could be biased.
In order to participate, subjects agreed to maintain their usual routine of shampooing, cutting, and coloring their hair and to avoid changing their current diet, medications or exercise routines for the duration of the study. The women of childbearing age also agreed to use a medically accepted form of birth control during the study. In addition, the following potential subjects were excluded from the study:
- Those with a history of allergy or intolerance to fish, seafood, vitamin C
- Those with any allergy to shampoos or conditions
- Those who were pregnant, planning to become pregnant, or nursing
- Those who had started using hormones during the last 6 months
- Those with had had an allergic reaction to drug or light therapy within the last 3 months
- Those who had used prescription drugs to affect hair growth within the past 6 months
- Those who had other hair loss disorders, like alopecia areata
- Those who had uncontrolled diseases, such as diabetes or other autoimmune disorders, thyroid disorders, hepatitis, or active skin conditions
These subjects were eliminated from the study to keep any noticeable changes to the hair as reliably related to the biotin administration as possible.
The Testing Procedure
The subjects in one group were administered the biotin twice daily for 180 days, with a selected area of the scalp selected for hair counts by the professionals conducting the study. All participants were examined after 90 and 180 days, and the results were carefully recorded. Significantly more control-treated subjects perceived improvements in overall hair volume, scalp coverage, and thickness of hair body after 90 days. Additional improvement after 180 days included hair shine, skin moisture retention, and skin smoothness. Perhaps even more exciting, no adverse events were reported either by the subjects themselves or by the medical professionals examining their scalps.
The conclusion the scientists who were conducting the study came to was stunning — the oral supplement vitamin biotin had been found in this preliminary study to be a safe and effective means of promoting significant hair growth in women with hair loss. If you, like most of us, are trying to maximize your appearance, having fuller, shinier hair is one thing that can make a major difference in the way the world views you.
