  2. Has a history of recurring dandruff symptoms or seborrheic dermatitis, evidence of excoriations, or other history that might indicate an inability to use the products supplied for the duration of the study.
  3. Has consistently used any medicated shampoos or anti-dandruff shampoo treatment products over the past year or at all during the two months prior to the Baseline visit.
  4. Has a history of alopecia areata, totalis, universalis or any other hair loss disorder except male pattern baldness.

5. Study Description

Brief Summary
The purpose of this study is to determine whether Minoxidil treatment affects hair growth in patients with male pattern baldness or androgenetic alopecia.
Detailed Description
The most common type of hair loss is androgenetic alopecia (AGA), also known as male pattern balding, or hereditary thinning. In AGA, there is a gradual transformation of large terminal hair follicles to miniaturized ones under the influence of circulating androgens that produce smaller and finer hairs with a shorter anagen cycle. This transformation, which can be seen as early as the prepubescent years, occurs only in certain regions of the scalp: the frontal hairline, top and vertex scalp. The temporo-occipital region is largely unaffected even in those with extensive balding. The first drug to be approved for the FDA for the treatment of AGA was topical minoxidil solution (TMS). Despite its successful use, the mechanism of action of TMS is not well understood. Minoxidil is a potent vasodilator and potassium channel opener, but its mechanism of action in promoting hair regrowth appears to be independent of its vasodilation properties. Improved knowledge of the changes in gene expression associated with AGA before and after treatment with TMS and compared to placebo may lead to a greater understanding of the underlying mechanisms of action of TMS. Furthermore, there is potential for identification of those patients who would best respond to or benefit from treatment.
