Hair is one of human’s most distinctive features and one important component in digital human models. However, capturing high quality hair models from real hairstyles remains di cult because of the challenges arising from hair’s unique characteristics: the view-dependent specular appearance, the geometric complexity and the high variability of real hairstyles. In this thesis, we address these c...

Skin of color comprises a diverse and expanding population of individuals. In particular, women of color represent an increasing subset of patients who frequently seek dermatologic care. Acne, melasma, and alopecia are among the most common skin disorders seen in this patient population. Understanding the differences in the basic science of skin and hair is imperative in addressing their unique...

AIM To analyze two phenotype characteristics--eye and hair color--using single-nucleotide polymorphisms (SNPs) and evaluate their prediction accuracy in Slovenian population. METHODS Twelve SNPs (OCA2 - rs1667394, rs7170989, rs1800407, rs7495174; HERC2 - rs1129038, rs12913832; MC1R - rs1805005, rs1805008; TYR - rs1393350; SLC45A2 - rs16891982, rs26722; SLC24A5 - rs1426654) were used for the d...

Hair dysplasias are congenital or acquired alterations which often involve the hair shaft. Hair shaft abnormalities are characterized by changes in color, density, length and structure. Hair shaft alterations often result from structural changes within the hair fibers and cuticles which may lead to brittle and uncombable hair. The hair of patients with hair shaft diseases feels dry and looks lu...

Hair is a very important for our self-confidence as well as a very important part of appearance and self-concept. It reflects our personality and hair loss or hair damages are considered aesthetic imperfections and social handicap. Outward part of the hair is a "hair shaft" keratin fiber structure sensible to external effects whether they are mechanical, physical or chemical. Excessive sun expo...

Differences in skin and hair color are principally genetically determined and are due to variation in the amount, type, and packaging of melanin polymers produced by melanocytes secreted into keratinocytes. Pigmentary phenotype is genetically complex and at a physiological level complicated. Genes determining a number of rare Mendelian disorders of pigmentation such as albinism have been identi...
