Spectral.F7 Astressin-B Topical Solution is technology that is years ahead of its time. DS Laboratories is the first biotechnology developer to synthesize and commercialize this cutting-edge peptide in a cosmetic product. Spectral.F7 offers a completely new mechanism of action and is therefore an important new tool in a program to maintain healthy hair. Spectral.F7 is very convenient to use: the product leaves a pleasant texture, not greasy or sticky.

• Nanosome encapsulation is used to enhance absorption.
• Additional compounds Prohairin beta4 and copper peptides are included to boost efficacy and stability.
• The treatment is completely free of common side effects like irritation, skin reactions, and other types of discomfort.
