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.
In newly published clinical research, the stress-hormone-blocking peptide astressin-B is credited with prevention of hair loss due to stress hormones.
Now Spectral.F7 is the first over-the-counter topical formula to incorporate astressin-B, whose mechanism of action offers a completely new modality. In trials conducted by DS Laboratories, the foremost innovator of topical therapies, astressin-B shows unique benefits and high efficacy. Our evaluation of efficacy with volunteers has shown very promising results when used either in early stages of thinning hair or in conjunction with other therapies in later stages.
Because this result was obtained through a totally new modality, 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.
