Evaluation of Scalp and Hair Shaft With Biologic Markers in African American and Caucasian Hair

July 3, 2018 updated by: Wake Forest University
The purpose of this research study is to better understand African American hair and scalp, its biologic appearance and how this relates to African Americans' perceptions of their hair and scalp health. Since most hair studies have looked at Caucasian hair and scalp, we will use a population of Caucasian subjects for comparison in evaluating various hair and scalp parameters.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 60 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Healthy female subjects between the ages of 21-60 will be enrolled in this study. These subjects will be recruited from Wake Forest University Health Sciences Dermatology clinic and our Institutional Review Board (IRB) approved advertising. Half of the participants will be African American and the other half will be Caucasian.

  • Must be willing to discuss hair care regimen currently and in the past
  • Must have washed hair at least 48 hours prior to initial study visit
  • Pregnant and nursing females will not be allowed in the study; a baseline pregnancy test will be done to exclude pregnancy on females of childbearing potential
  • Must be >6 months (26 weeks) postpartum
  • Must have sufficient contrast between scalp skin color and hair color
  • Must have hair at least 2 inches long
  • May have mild itching and mild scaling of the scalp
  • Must be willing to have hair clipped and shaved to 1mm within an approximately 2.5cm test site
  • Must be in good stable general health, with no current infections.

Exclusion Criteria:

  • May not have sewn-in or glued hair pieces or extensions at the time of the study
  • Must not cut hair during the study
  • Must not have hair loss beyond what is considered normal in the opinion of the Investigator at the time of the study
  • Must not color hair or have other salon-type procedures (relaxer, permanent, highlighting, etc.) performed within 2 weeks of the initial visit
  • Must not have any other underlying scalp disorder that could interfere with the test procedures or findings
  • Must not have lost ≥10% of body weight within the past 12 months
  • Must not have been on a weight reduction program overseen by a physician or nutritionist within the past 12 months
  • Has used hair growth products e.g. minoxidil in the past 18 months
  • Has undergone a hair transplant or scalp reduction surgery
  • Has participated in a hair growth study within the past 15 months
  • Is currently participating in another clinical study at this or any other facility
  • Is taking, for a chronic condition, any prescription or over the counter medication(s) that in the opinion of the Investigator are likely to affect the hair properties (e.g. immunosuppressive agents, corticosteroids; or chronic use of anti-inflammatory medication)
  • Application of any over-the-counter or prescription drug to the scalp on a routine basis within the past 3 months including but not limited to retinoids (e.g. retinal, tretinoin, retinyl palmitate, retinyl acetate, retinyl propionate), topical corticosteroids, benzyl peroxide, or any topical hormone therapy (e.g. Eterna 27)

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
