A growing body of evidence shows that surface\u2010enhanced Raman spectroscopy (SERS) could be a confirmatory, minimally destructive, and fully noninvasive analysis of hair colorants. In SERS, a signal that provide the information about the chemical structure of both permanent and semipermanent dyes present on hair is enhanced by a million\u2010fold using noble metal nanostructures. However, it is unclear whether the information of hair colorants can be revealed if hair was contaminated or exposed to harsh environments such as sunlight and heat. In this work, we determine the effect of a short\u2010 and long\u2010term heat exposure on SERS\u2010based analysis of hair colored with blue and red permanent and semipermanent dyes. We found that short and especially long\u2010term heat exposure at 220\u00b0C could alter chemical structure, and consequently SERS spectra, of permanent and semipermanent colorants. This thermal degradation of permanent dyes complicates their direct identification using SERS. We also found that partial least squares discriminant analysis can be used to overcome this issue allowing for highly accurate identification of both permanent and semipermanent dyes on colored hair that was exposed to 220\u00b0C for 6\u201312\u2009min. These results show that heat exposure of colored hair should be strongly considered upon their SERS\u2010based examination to avoid both false positive or false negative identification of chemical dyes.<\/jats:p>","DOI":"10.1111\/1556-4029.15235","type":"journal-article","created":{"date-parts":[[2023,3,15]],"date-time":"2023-03-15T12:44:30Z","timestamp":1678884270000},"page":"807-814","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Elucidation of the effect of heat exposure on hair colored by permanent and semipermanent colorants using surface\u2010enhanced Raman spectroscopy"],"prefix":"10.1111","volume":"68","author":[{"given":"Mackenzi","family":"Steczkowski","sequence":"first","affiliation":[{"name":"Department of Entomology Texas A&amp;M University  College Station Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6040-4213","authenticated-orcid":false,"given":"Dmitry","family":"Kurouski","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Biophysics Texas A&amp;M University  College Station Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,3,15]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.4103\/0974\u20107753.125610"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/cber.18940270194"},{"key":"e_1_2_9_4_1","first-page":"411","article-title":"Oxidation products of p\u2010phenylenediamine in hair dyes","volume":"19","author":"Dolinsky M","year":"1968","journal-title":"J Soc Cosmetic Chemists"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/cosmetics2020110"},{"issue":"4","key":"e_1_2_9_6_1","first-page":"662","article-title":"Extraction, PCR amplification and sequencing of mitochondrial DNA from human hair shafts","volume":"18","author":"Wilson MR","year":"1995","journal-title":"Biotechniques"},{"issue":"2","key":"e_1_2_9_7_1","first-page":"1","article-title":"Forensic hair comparison: background information for interpretation","volume":"11","author":"Oien CT","year":"2009","journal-title":"Forens Sci Commun"},{"key":"e_1_2_9_8_1","first-page":"202","volume-title":"Criminalistics: an introduction to forensic science","author":"Saferstein R","year":"1995"},{"key":"e_1_2_9_9_1","first-page":"79","volume-title":"Forensic examination of hair","author":"Harding H","year":"1999"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac504068a"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.forc.2017.08.001"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0AY01068E"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.analchem.6b01597"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1039\/c7cc07951f"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1039\/c2cp42598j"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.anchem.1.031207.112814"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja104174m"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.275.5303.1102"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac504405u"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2022.123762"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/1556\u20104029.15165"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467\u20102494.1984.tb00378.x"},{"key":"e_1_2_9_23_1","unstructured":"Dyson.Dyson scientists delve into the damage caused by lockdown DIY hairdressing.2020.https:\/\/www.dyson.com\/newsroom\/features\/technology\/dyson\u2010hair\u2010scientists\u2010on\u2010hairstying.
