However, the possible damage to the hair fiber after its application is low known and/or published in the literature.Aims: This work aims to characterize hair locks treated with glyoxylic acid compared to traditional alkaline straighteners such as sodium and guanidine hydroxide and ammonium thioglycolate.Materials and methods: The morphology of the hair cuticles was observed by scanning electron microscopy. Protein loss was assessed by the Lowry method modified by Peterson and as mechanical properties that were expressed in terms of tensile strength.Results: All products (sodium and guanidine hydroxides and ammonium thioglycolate) caused protein loss of about 2.5 μg/g, except glyoxylic acid that caused the worst damage (3.5 μg/g), in relation to the untreated (virgin) hair (1.12 μg/g), indicating that the chemical treatments can cause hair damage in both cuticles and cortex. The force to break the fibers treated with traditional straighteners based on sodium hydroxide, guanidine hydroxide, and ammonium thioglycolate was statistically the same.Conclusion: The treatment with glyoxylic acid showed rupture tensile statistically equivalent to the alkaline straighteners. The mechanism of action of glyoxylic acid does not appear to be based on breaking and rearrangement of disulfide bridges, but altered them, that influenced the hair strength. However, it is also essential to consider other factors relevant: technical application technique, reaction time, and interval of reapplication of the product, as this can change the pattern of the results obtained.","PeriodicalId":14417,"journal":{"name":"International Journal of Trichology","volume":"14 6","pages":"197-203"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9273458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For female pattern hair loss (FPHL), diagnosis is primarily clinical. In the early stages, it can be confused with other conditions. Histopathology is the diagnostic method of choice but requires multiple biopsies and can be disfiguring. Trichoscopy is an alternative noninvasive, rapid tool.Aim: The aim of this study is to study the hair density and hair diameter variance in relation with severity grading of FPHL.Settings and design: Cross-sectional study.Materials and methods: Ninety women aged 18 years and above were included in this cross-sectional study conducted at the dermatology department of Bangalore Medical College and Research Institute. Trichoscopic examination was done with a videodermoscope (Firefly DE300) at 20 and 70-fold magnification. Only those patients who met the trichoscopic diagnostic criteria for FPHL were included.Statistical analysis used: Descriptive statistics, ANOVA, and Spearman's correlation test for fitness of good, using Microsoft Excel data analysis tools.Results: Increase in disease severity from grade one to grade three positively correlated with a decrease in hair density over the frontal scalp (P < 0.001) and the occipital scalp (P < 0.001), decrease in average hair shaft diameter over both frontal and occipital scalp (P < 0.001).Conclusion: Trichoscopic tools, particularly hair density and hair diameter variance over both frontal and occipital scalp can be useful to help determine FPHL disease severity and its progression.","PeriodicalId":14417,"journal":{"name":"International Journal of Trichology","volume":"14 5","pages":"162-171"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9674057/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40697613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microneedling is used for uniform delivery of topical agent to relatively larger areas may prove to be more efficacious than traditional ILCS. The present study prospectively compared microneedling to traditional intralesional delivery of triamcinolone acetonide (TA).Materials and methods: Prospective randomized comparative study in 60 patients of AA restricted to scalp not requiring systemic treatment randomly divided into two equal groups. Group 1 patients underwent microneedling with local application of injectable TA and Group 2 patients were given injectable TA intradermally for a total of three sessions at 3 weeks interval.Results: A mean regrowth of 66.36% in Group 1 and 69.75% in Group 2 at week 9 was seen which was comparative with no significant statistical difference between the two groups (P = 0.664). Thirteen patients achieved 100% regrowth at week 9 in Group 1 and 16 patients achieved 50%-99% regrowth in Group 2.Discussion and conclusions: ILCSs have been cornerstone in the treatment of limited AA, but depth of injecting drug cannot be controlled, microneedling whereas is an effective drug delivery system and also causes release of growth factors. In this study, injectable TA used intralesionally and topically with microneedling had nearly similar efficacy in causing regrowth of hair with microneedling resulting in a more uniform but less dense regrowth of hair with lesser adverse effects.","PeriodicalId":14417,"journal":{"name":"International Journal of Trichology","volume":"14 5","pages":"156-161"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9674065/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40697617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the inner surface cord-like linear structures with serpiginous, tortuous traject were seen, associated with some cavities.Conclusions: These findings suggest that this condition is due to some deficient protein synthesis/arrangement, not only due to cavities in the hair cortex. The term Tiger tail hair is a descriptive clinical term of little scientific rigor. This disorder has been reported mainly as pili annulati; however, rings are not observed. In analogy to pili canaliculi, in which well-formed grooving is observed in the hair surface, we suggest the term pili microcanaliculi to describe this condition, based in the ultrastructural findings.","PeriodicalId":14417,"journal":{"name":"International Journal of Trichology","volume":"14 5","pages":"172-174"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9674060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40697696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
