Brief Summary

The goal of this study is to determine how safe and effective it is to improve hair growth by applying a serum daily on the scalp of men and women with 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 usage of Xtressé serum.

Participants who qualify will complete 4 visits after voluntary consent has been given. Participants will be given 4 bottles of serum to use during the study. The product will be applied daily over a 4-month period. Photographs and scalp analysis will be performed at each visit to measure changes in hair volume, thickness, and growth. Participants will complete a survey at the end of the study.

• Follow study rules such as avoiding certain medications and treatments
• Provide information on any medications, treatments or reactions that started after the study began
