DS Laboratories Spectral F7 Hair Booster Serum 60ml — Astressin-B
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
- Astressin-B — a potent peptide that targets the corticotropin-releasing factor (CRF) pathway associated with stress-induced hair loss, supporting follicle health and reducing shedding
How to Use
- After applying Spectral DNC-N or Spectral RS to a clean, dry scalp, apply Spectral F7 to the same thinning zones
- Massage gently until fully absorbed
- Do not rinse — allow to dry before styling
- Use daily as part of your hair care routine
