Understanding hair follicle structure & pigmentation genetics: expression/methylation differences found in hair growth location.
Study on What Affects Hair Color Differences
Brief description of study.
The purpose of this study is to research on the genes that cause different hair colors in an individual using the genetic information extracted from the hair samples the study participants provide.
Detailed description of study
The purpose of this study is to investigate why there are differences in hair color between scalp and beard hair by studying genetic material and pigment measures obtained from the hair follicle/bulb samples collected from the participants.
Eligibility of study
You may be eligible for this study if you meet the following criteria:
- Conditions: healthy,hair
-
Age: 18 years - 100 years
-
Gender: Male
Inclusion Criteria
European ancestry (at least in part to show color variation)
Has multiple colors on the beard (no dyeing)
Exclusion Criteria
Dyed hair
The purpose of this study is to investigate why there are differences in hair color between scalp and beard hair by studying genetic material and pigment measures obtained from the hair follicle/bulb samples collected from the participants. This study investigates the genes that cause different hair colors in an individual using the genetic information extracted from the hair samples the study participants provide.
Participants will provide hair samples from their scalp and beard. The samples will be used to study genetic material and measure pigments to understand the differences in hair color. No payment will be provided for participation.
- Who can participate: Adults of European ancestry with natural multiple colors in their beard hair can participate. Individuals with dyed hair are not eligible.
- Study details: Participants will provide hair samples from their scalp and beard for genetic and pigment analysis to understand hair color differences.
