Telogen effluvium is diffuse hair loss from the scalp lasting for 6 months but is self-limiting. The present study was undertaken to analyze data obtained from multiple investigator prescribing Q – Sera Hair Serum (combination of Biochanin A, Acetyl Tetrapeptide-3, Bioactive Signaling Molecules (Cytokines), Ethylpanthenol and Inositol) for diffuse hair loss. The subjects were on once daily application of Q – Sera Hair Serum for 21 days. The effectiveness of the product was based on reduction in number of hair loss and overall improvement as assessed by the investigators. 89.36% of the subjects reported reduction in the daily hair loss within 21 days. The percentage of improvement in the overall appearance of the hair was 61% according to the investigator’s assessment. Thus this prescriber’s observational study found the product Q – Sera Hair Serum to be effective in improving hair loss as a short term therapy.
