Abstract

OBJECTIVE:

The purpose of this six-month, randomized, double-blind, multi-center, placebo-controlled study was to determine if the administration of a new oral supplement will promote terminal hair growth.

DESIGN:

A randomized, double-blind study.

SETTING:

Two private practices (dermatology and facial plastics).

PARTICIPANTS:

Women 21 to 75 years of age with self-perceived thinning hair.

MEASUREMENTS:

The primary efficacy endpoint was the change in terminal and vellus hairs in a 4cm(2) target area of the scalp after 90 and 180 days of treatment. Secondary endpoints were change in hair diameter and responses to Quality of Life and Self-Assessment questionnaires.

RESULTS:

Subjects treated with the new oral supplement achieved a significant increase in the number of baseline terminal hairs at 90 and 180 days (for each, p<0.0001, respectively) and were significantly greater then placebo (p<0.0001). Treatment with the new oral supplement was also associated with a significant increase in baseline terminal hair diameter after 90 (p=0.006) and 180 days of treatment (p=0.001) which was significantly greater than placebo at the end of the study (p=0.003). Improvements in hair growth and hair diameter were associated with significant improvement in most responses to Self-Assessment and Quality of Life Questionnaire responses. There were no adverse events.

CONCLUSION:

The daily administration of a new oral supplement was associated with significant increases in the number of terminal and vellus hairs and hair diameter. Most study participants believed the use of the oral supplement resulted in significant improvement in skin and hair quality and quality of life.
