Article Synopsis
  • Dandruff is a persistent scalp condition that can be influenced by various environmental and personal factors, leading to changes in scalp health that may require treatment like Selenium disulfide (SeS2) shampoo.
  • Research focused on how SeS2 shampoo affects dandruff severity, scalp microbiome, and sebum properties during treatment and after resuming normal conditions.
  • The study found that SeS2 significantly reduced dandruff symptoms and harmful microbes in the scalp, improved the balance of beneficial bacteria, and enhanced the quality of scalp oils, showing good tolerance from users even after stopping treatment.

Article Synopsis
  • Scalp seborrheic dermatitis (SD) is a recurring inflammatory condition linked to changes in scalp microbiota, which was explored in a study involving 68 subjects undergoing treatment with ketoconazole and selenium disulfide (SeS).
  • After one month of 2% ketoconazole treatment, subjects showed a significant reduction in clinical symptoms like flaking and erythema, along with changes in fungal diversity, particularly a decrease in Malassezia spp. levels.
  • The addition of SeS further improved symptoms and reduced Staphylococcus spp. counts, indicating its potential role in enhancing scalp health and preventing future flare-ups of SD.

Objective: To determine, in vivo, the density, growth rate and percentage of anagen phase follicles of body hairs present on five different skin sites (axilla, cheek, chin, leg, upper-lip) of women and men from four different ethnics (African, Caucasian, Chinese, North African). The same characteristics of terminal hairs from the nape of all subjects were recorded as references.

Methods: The photo-trichogram technique was used on all skin sites (of different sizes) at variable times (2 or 3 days) post shaving of small skin areas (a few cm ).

Based on previous findings, from a worldwide study, classified the shapes of human hair into 8 major types, from straight to highly curly. This clearly extended the usual classification of hair into African, Asian or Caucasian types. However, determinations of hair growth parameters and hair density were excluded from such studies.

Skin ageing and gender influences on the scalp have been seldom studied. We revisited the changes in the interfollicular scalp. The study was performed on a population of 650 volunteers (300 women and 350 men) for over 7 years.

Background: Ageing of the skin, being chronological or sun induced is highly documented. Scalp, as a specific skin site, has, however, received little attention. This work attempted to describe functional and structural alterations that occur in scalp skin with ageing.

Background: For many years, cosmetic scientists have attempted to measure the physical features of human hair, such as its shape and colour, as these can be artificially modified using cosmetic products. With regard to hair shape, previous anthropologic studies have emphasized its variability within and between human ethnic groups. Many studies have broadly distinguished three ethnic human subgroups: African, Asian, and Caucasian.
