0
Study will determine the change in microbial composition following the application of 1e8 cfu per dose serum containing Micrococcus luteus Q24 serum to the scalp. The statistical analysis will be carried out to compare the participants skin swab data from baseline to 15 days across one site with a level of significance of p\<0.05. Overall colonization based on percentage of population colonized for different interventions will also be analyzed using appropriate statistical analysis software. Analysis will be performed using bacterial genome sequence analysis of the skin swab samples collected.
