DS Labs is First with Astressin-B

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.

This formulation contains compounds that have been evaluated in clinical trials and subsequently tested and optimized in our own extensive trials. These materials are encapsulated in a range of Nanosome microspheres to enhance absorption, and others are delivered in free form for optimal delivery. Our evaluation of efficacy with volunteers has shown very promising results when used either in early stages of thinning hair or in conjunction with others therapies in later stages.

Technological Highlights

  • A totally new mechanism to stimulate hair follicles.
  • May induce follicles into anagen growth phase.
  • Stress-blocking peptide astressin-B.

Who should use Spectral.F7?

Men and women concerned about thinning hair and overall hair health can combine Spectral.F7 with existing therapies such as Spectral.DNC for maximum benefit, or they can use the product as an effective stand-alone treatment.

Spectral.F7 features astressin-B, a peptide (protein fragment) with a very complex sequence newly discovered to block the receptors for corticotropin-releasing factor (CRF), involved in the stress response. An in-vivo murine study investigated whether CRF blockade might influence hair growth when stress hormones are over-expressed, and it showed a promising new mechanism of action on atrophic hair follicles.

Spectral.F7, from DS Laboratories, is the first topical solution to incorporate astressin-B.

제품 사용법

Shake before use.

To enhance an existing topical therapy, 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. 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.


Spectral.F7 is for topical use only.

Di water, astressin-B, prohairin-ß4, lecithin, GHK-CU, sodium oleate, glycerin, phenoxyethanol, caprylyl glycol.
