Quick Overview:

A hair growth booster in conjunction with existing treatments. A single-line therapy for early stage thinning hair. Leaves hair a pleasant texture, not greasy or sticky.


Spectral.F7 Hair Revitalization Efficacy Booster

Spectral F7 is an efficacy booster agent. Now men and women in treatment for thinning hair can add astressin-B, a complex new peptide, to maximize hair-follicle benefits, because Spectral.F7 is the first solution to incorporate this protein fragment for human use in a topical booster agent. Spectral.F7 augments primary therapies like Spectral.DNC-N, and it can serve as an effective stand-alone treatment in early stages of thinning.

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.

This peptide has received extensive media coverage due to remarkable results observed in laboratory animals. Further testing by DS Laboratories on human volunteers revealed a surprisingly high level of efficacy.

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.


  • Spectral.F7 features ultra-high-purity astressin-B, a complex peptide with 33 amino acids.
  • Nanosome encapsulation is used to enhance absorption.
  • Additional compounds Prohairin β4 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.
  • It is so new and unique that it is revolutionary.

Directions for Use

To enhance a primary therapy like Spectral.DNC-N® or minoxidil, apply 10 sprays of Spectral.F7 and massage it into the scalp after your regular morning treatment or before your regular evening treatment. Wait at least 10 minutes between products. To use Spectral.F7 as a stand-alone therapy, usually in the early onset of thinning, apply it both morning and evening. Spectral.F7 is for topical use only.



Frequently Asked Questions

The introduction of Spectral.F7, a new topical hair-growth booster, was met with both excitement and skepticism, which included questions about the authenticity of the astressin-B contained in it. DS Laboratories is the first biotech developer to synthesize and commercialize the astressin-B peptide for human use in a cosmetic.

Indeed, the astressin-B contained in Spectral.F7 is authentic. The DS Laboratories team of chemists worked quickly to develop it, and the company invested heavily to introduce it first. Spectral.F7 was released less than a year after publication of the peptide

    I heard about Spectral F7 from DS Laboratories and got it first from Fabove. It is great for FABOVE as so many people out there are so excited to try this new product. Spectral F7 was touted by DS Labs to enhances the efficacy of other hair regrowth treatments. I use it with DNC-L on Sundays, and the new DNC-N on weekdays. Spectral F7 looks, smells, sprays like water. Hopefully I can see the better results soon.
