Study Summary
The purpose of this study is to compare the differences in various chemical and biologic parameters of scalp and and hair parameters between young and old Caucasian females. The hair state and scalp blood flow in younger and older age groups with typical hair care practices will be qualified by measuring various parameters of the hair shaft and scalp with correlation back to hair and scalp satisfaction as measured in the subject. This is a single center study with an anticipated 4 month enrollment period. The investigators will compare various scalp and hair parameters between young and old Caucasian females by obtaining the following biological and chemical/structural information. Hair growth rate, anagen to telogen ratio, hair density (determined via phototrichogram and digital imaging), Vascular blood flow (Laser Doppler Flowmetry), Histamine stimulation and Hair diameter (clipped hairs). In addition, a detailed questionnaire will be administered to each subject regarding satisfaction of the subject's hair state, including typical hair care regimens and symptoms in scalp and/or hair shafts. This information will be correlated to the biologic and chemical/structural information about hair and scalp health. Approximately 50 healthy, Caucasian female subjects will be enrolled in this study. Twenty five participants will be 19-25 years-old and 25 participants 60 years or older. There will be two visits, Baseline and approximately 48 hours after baseline.
Primary Outcome
Two areas will be tested in total; one site on the scalp (parietal scalp: which is the area between top of the scalp and either ear) and one area on the forearm. Study staff will take a template and mark off the designated scalp area with a marker. This temporary ink mark will be used as a reference point. The hairs in the marked area (approximately the size of a nickel) will be cut and clipped to 1 millimeter in length for analysis. A digital photographic image of the scalp and hair shafts (pho
