The breakthrough booster for stress-related hair shedding. DS Laboratories Spectral F7 incorporates Astressin-B — a powerful peptide specifically developed to address the stress hormone CRF (corticotropin-releasing factor) pathway that triggers hair loss. Applied alongside Spectral DNC-N or Spectral RS, it targets shedding from a different biological angle for a comprehensive approach to thinning hair.

Key Benefits and Features
  • Stress-Related Shedding — Astressin-B targets the CRF pathway that triggers stress-related hair loss, addressing a common but often overlooked cause of shedding
  • Follicle Support — supports follicle health and helps address shedding at the source
  • All Hair Types — suitable for all hair types and both men and women
  • Lightweight Leave-In — fast-absorbing, non-greasy formula for daily use
  • Booster Formula — designed to enhance results when used alongside Spectral DNC-N or Spectral RS
Who It's For

Designed for adults experiencing hair thinning or shedding — particularly effective for stress-related hair loss. Use as a daily booster alongside Spectral DNC-N or Spectral RS for comprehensive thinning-hair support.

Key Ingredients

How to Use
