Datasets for: Prior bleaching of virgin or colored hair has minimal impact on SERS-based hair dye identification

These datasets were used to generate the results in the corresponding manuscript. Information on what each dataset contains can be found below: BleachHair_Raw: Raw SER spectra of all dyed/undyed hair. BleachSol_Raw: Raw SER spectra of dyes and bleaches alone. processed_BleachComb: Individual bleach solutions were labelled together (e.g., BV1-BV3 = B). processed_BleachNoComb: Individual bleach solutions were labelled separately (e.g., BV1, BV2, BV3). processed_BleachSol: Processed SER spectra of dyes and bleaches alone. For label characterizations, please consult the manuscript.
