DS Laboratories Spectral.F7 is the first hair treatment to incorporate Astressin-B, a peptide that is very long and complex, with a 30+ amino acid sequence, and includes a cyclo-lactam bridge. Astressin-B contains some unusual amino acids, and unlike virtually all peptides in cosmetic use, it is particularly difficult to synthesize. This advancement in the art and science of hair solidifies DS Laboratories reputation for developing cutting-edge technologies and bringing them to our customers first.

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 was developed to be used as a booster in conjunction with existing treatments. For early stage thinning hair, it can be used as a single-line therapy. It is very convenient to use, and the product leaves a pleasant texture, not greasy or sticky.

• To enhance an existing topical therapy, apply 10 sprays of Spectral F7 and massage it into the scalp after your regular morning treatment.
• Wait at least 10 minutes between products.
• If Spectral F7 is used as a stand-alone therapy, usually in the early onset of hair thinning, then use it both morning and evening.
