DS Laboratories Spectral F7

This efficacy booster agent is added to the treatment programs of men and women who already use a primary hair stimulating product, like Spectral.DNC-N® who want to optimize benefits.◊*

Use of the booster is recommended to help combat thinning and improve folliculair health. It works through a unique mechanism of action, which may not be addressed by minoxidil, finasteride, or other agents. In early stages of thinning, Spectral.F7 can serve as an effective stand-alone treatment.◊*

Complex new astressin-B peptide delivers 33 amino acids to hair follicles◊*

Users concerned about hair thinning gain a unique advantage from Spectral.F7, because this product is the first topical booster developed for use to deploy the evolutionary peptide astressin-B.◊*

This 33-amino-acid protein fragment has an acetylated N-terminus, an amidated C-terminus, and a lactam bridge containing the amino acids methylleucine, norleucine, D-phenylalanine, leucine, threonine, histidine, arginine, glutamate, glutamine, valine, alanine, lysine, isoleucine, and others.

Formation of the amide bond on the C-terminus is achieved by using a Rink amide resin, which is the solid support and starting point for peptide synthesis. Completion of synthesis and subsequent cleavage from the resin leaves the C-terminus with an amide bond intact.

Additional components of Spectral.F7 include Proharin-β4 (octapeptide 2), bis(tripeptide-1) copper acetate, and lecithin used in Nanosome encapsulation for enhanced absorption.

To be effective, ingredients must be absorbed deeply, predictably, in the right concentrations, and they must remain on site long enough to perform. Among the many innovations delivered by Spectral.F7, Nanosome encapsulation accomplishes these objectives.

Nanosome technology wraps pure active compounds within tiny liposomal microspheres made of phospholipid bilayers that have a composition similar to human scalp.

While standard products remain on the surface and dissipate quickly, Nanosomes mean that Spectral.F7 can penetrate the scalp deeply and release ingredients gradually.

So users benefit from maximum performance over a 12-hour period.
