Type 2 hair in general has a looser curl pattern that makes it easy for natural oils to moisturize the hair shaft. 2C textures are known for a thick and defined wavy pattern that tends to struggle with unwanted frizz. Strands in the 2A range have waves that can lack body and volume, while 2B hair has S-patterned waves that are easy to style but are prone to frizz. That means products like creams and oils that can deeply penetrate your strands to achieve lasting hydration are a necessity. All type 4 hair is typically dry and can use an extra boost in moisture. 4C hair textures have tight, densely packed coils that are prone to extreme dryness. Hair in the 4A range is dense with a visible curl pattern that can lack definition, and 4B hair has a zig-zag pattern that makes it prone to dryness and breakage. It’s also essential to keep the texture of your hair in mind. Our study suggests that careful assessment of the target population prior to the implementation of forensic DNA phenotyping to case work is beneficial.The Best Pre-Poo To Use Based On Your Hair TypeĪs mentioned, there are a variety of treatments you can use when learning how to pre-poo hair. To our knowledge, this has not been reported in other studies. ![]() Assessment of phenotype-genotype associations of eye colours using a quantitative eye colour score (PIE-score), revealed that rs12913832 AA individuals of Norwegian descent had statistically significantly higher PIE-score (less brown eye colour) than individuals of non-northern European descent. Utilising the prediction guide approach increased the correct predictions to 75%. The main error was observed for individuals with brown hair colour that were predicted to have blond hair. For hair colour, 65% of the individuals were correctly predicted when using the highest probability category approach. We also observed that more than half of the incorrect predictions were for individuals carrying the rs12913832 GG genotype. Therefore, the error rates of the overall eye colour predictions were 37% with no predictive probability threshold (pmax) and 26% with a probability threshold of 0.7. None of the individuals was predicted to have intermediate eye colour. The AUCs for blond (0.72) and brown (0.70) hair colour were considerably lower. Prediction accuracies in terms of AUC were high for red (0.97) and black (0.93) hair colours, as well as blue (0.85) and brown (0.94) eye colours. In samples with DNA input < 125 pg, false homozygotes were observed with as many as 92 reads. DNA-profiles were successfully typed with DNA input down to 125 pg. As part of an in-house validation, this study presents the genotyping and predictive performance of the HIrisPlex SNPs in a Norwegian study population, using Verogen’s ForenSeq™ DNA Signature Prep Kit on the MiSeq FGx system and the HIrisPlex webtool. ![]() To genotype a DNA sample, massively parallel sequencing (MPS) has brought new possibilities to the analysis of forensic DNA samples. The HIrisPlex model for simultaneous eye and hair colour predictions was developed for forensic usage. Prediction of eye and hair colour from DNA can be an important investigative tool in forensic cases if conventional DNA profiling fails to match DNA from any known suspects or cannot obtain a hit in a DNA database.
