RESULTS 1. Study selection procedure From the literature review study, it yielded a total of one hundred and sixty-two studies, from this fifteen of the studies were strongly relevant based on their title and also the data from the abstracts. Among these fifteen related and relevant titles and abstracts, two out of the fifteen titles investigated animals (Avci et al., 2014), and also two did not study the Androgenetic Alopecia (AGA).This left us with only eleven possible studies, and these were evaluated where one was found to be a case report, one was a case series, four were cohort studies, and the remaining five were randomized controlled trials (RCTs) 2. The study characteristics The studies yielded a total of four hundred and…show more content…
Considering the frequencies per week and the time duration per session, we can say that the differences were negligible. Considering the changes in the hair, a number of different methods were utilized which include the use of the area trichogram (UAT), phototrichogram, global photography, investigator global assessment and without forgetting the use of the direct scalp hair count (Avci et al., 2014). After this was done, the hair analysis was done to by the experts and also with the help with the help of an investigator and also through use of the computer software. Using this different hair analysis and counting tools, a number of outcomes were achieved. However what was important to this research paper is the total hair count i.e. what is sometimes referred to us as the hair density, the hair thickness i.e. the diameter of the hair shaft or the tensile strength. Furthermore the study included the secondary outcomes which were aimed at determining the level of the patient’s satisfaction and also the global assessment of the subject under study (Leavitt et al., 2009). 3. Study quality control All the randomized controlled trials (RCTs) were done randomly as the name itself suggests. Many observational studies blinded their outcomes assessors by blinding them to either the side of the patient that received treatment or through blinding of the reviewers in chronological order of the way in which the photographs of the scalp were taken or
