The patient is then asked to look at the photographer and order sildalis 120mg with visa, after center parting the hair buy generic sildalis 120mg online, asked to tip the head down to look at the oor. An alignment is again obtained and the focusing steps are repeated before the photo is taken. The chin support rotates into a 45-degree position for the temporal hairline view. At follow-up it is very important to have the baseline images viewable either as reference prints or on screen so exact angles can be matched. Macrophotography coupled with computer analysis offers a quantitative method for understanding the dynamics of hair (7 10). Hair count, width, and color can be made with a single visit using a single image. Anagen/telogen ratios (referred to as a phototrichogram) and growth rate can be calculated by having the patient return 1 3 days after the rst photo and measuring the anagen hairs (hairs which have grown). In Cauca- sian patients with light color hair, the application of hair dye on the target site will aid visual- ization (lash and eyebrow dye is preferred). Selecting an appropriate target site is critical when trying to understand the current phys- iological state of the hair loss condition. Most clinical trials have relied on the selection of a representative target site in a transitional area with active thinning. If you are planning on fol- lowing the patient over time, placing a permanent dot tattoo to identify the exact same area at follow-up may be necessary. Recording measurements from the nose and ears may be useful in nding the dot tattoo at follow-up but are not adequate on their own to accurately identify the same area. While clipping of the target area to ~1 mm in length is not necessarily required, it is currently the most common method (clipping to mm may be required if you are capturing anagen/telogen ratios or growth rate 1 3 days later). The bigger the better from a statisti- cal perspective, but your patient might not agree. Currently, most clinical studies have used a 1 cm2 circular area with a dot tattoo placed in the center to allow for relocation of the same target site at follow-up visits. The camera is tethered to the computer, allowing for complete camera control, analysis, and image management. The combination of a coupling uid (clear hair gel works well) and the fact that the hairs in the target site are forced at against the scalp by the contact plate allow for more accurate width and length measurements. There are several software systems available for detecting and analyzing scalp hair (11 13). Considerations include reliability of measurement, types of measurement, ease of use, and ultimately cost. For clinical studies, the system used must also be validated and conform to the requirements of regulatory authorities. Current measurements include hair count and width from a single visit, and anagen/telogen ratios and growth rate if the patient returns two days later. By capturing and storing individual hair length and width measurements, any threshold can be selected and reported. By having and following a basic photographic protocol, reproducible high quality images can be obtained that can be used for both qualitative and quantitative analysis.

Initial studies were limited to gross and light microscopic exami- nation of the hair follicle. Further progress was made later in the twentieth century through sci- entic research involving molecular biology. Gross and microscopic hair follicular analyses were primarily performed on white populations. A basic understanding of the differences in the physical, morphologic and histologic hair properties of the different ethnic groups is important in the assessment, diagnosis, and management of patients with hair loss. In addition, a working knowledge of the microscopic anatomy of the normal hair follicle in both vertical and horizontal sections is vital in the understanding of hair follicle disease, leading to accurate interpretation of scalp hair biopsies. Microscopic cross-sectional views of an Asian hair shaft reveal a round or oval shape, dark pigmentation, and a wide diameter. The curvature of the black hair shaft is programmed from the follicular bulb (Fig. Hispanic hair has a structure comparable with white hair, in the authors experience. There are approximately 5 million hair follicles on the body and around 100,000 to 150,000 scalp hairs present on a normal scalp.
