Study Evaluating Xtressé Gummy Supplement in Women With Self-Perceived Thinning Hair

Pilot Study to Evaluate the Efficacy and Safety of Xtressé™ Gummy-Based Nutraceutical Supplement in Women With Self-Perceived Thinning Hair

The goal of this study is to determine how safe and effective it is to improve hair growth using an active gummy treatment in women with self-perceived thinning hair.

The main aims of this trial are:

1. To confirm using photographic analysis, changes in the quality, volume, and thickness of hair.
2. To gauge patient satisfaction with hair changes and application process.
3. Monitor and report any adverse events associated with the daily intake of Xtressé

Participants who qualify will complete 5 visits after voluntary consent has been given. Participants will be given a 30-day supply of the gummies at each visit over a 4-month period. Photographs and scalp analysis will be performed at each visit to measure changes in hair volume, thickness, and growth.
