Hold on to more hair longer with Spectral.RS. Arrest hair shedding. Stimulate hair growth. Increase the diameter of hair strands. This nonirritating, drug-free, leave-in treatment delivers powerful results.
Targets numerous causes of hair thinning
Unlike simple minoxidil products to treat androgenic alopecia, this formula addresses multiple etiologies, including perifollicular fibrosis, stress, hormones, medications, and nutrition.
Drug-free for thicker hair without side effects
Spectral.RS derives hair-growth effects from natural extracts, peptides, and ion-channel openers that mimic minoxidil, plus antioxidant and anti-inflammatory agents for scalp health.
Advanced Nanosome ingredient delivery
Our proprietary Nanosome delivery technology encapsulates key compounds in microscopic liposomes to penetrate deeper into epidermal cells for maximum hair growth results.
  • Men and women concerned about hair loss
  • Men and women in early stages of thinning hair
  • Those wishing to retain existing hair and prevent future shedding.
Shake well before use. Apply six sprays twice per day directly on the affected area. Rub in the liquid evenly. Wash hands with soap and water immediately after use. This is a leave-on treatment, which should not be rinsed after application. Use regularly as directed, without interruption, for optimal hair growth. For best results use Revita Shampoo & Conditioner to increase the efficacy of your treatment.

Clinical Studies
First and foremost, DS Laboratories is a technology company aggressively focused on innovation. All our products have active pharmaceutical ingredients that ensure the best quality and provide high added value in the care of hair problems.
To preserve hair and prevent shedding, Spectral.RS results from volumes of biotechnical research on the causes of hair loss, including perifollicular fibrosis, stress, hormones, medications, and nutritional deficiencies, as well as androgenetic alopecia, alopecia areata, and telogen effluvium. The formula combines multiple compounds known to support hair regrowth.
Biotinoyl Tripeptide-1
To achieve longer, stronger hair growth, this peptide promotes microcirculation in hair follicles and boosts production of keratin, the fibrous protein that forms the chemical basis of hair fibers.
To increase hair density, this key compound mimics ion-channel openers like minoxidil. It inhibits perifollicular fibrosis, in which collagen at the roots becomes rigid, common in alopecia.
This anti-inflammatory agent works for hair regrowth through biochemical processes like energy transfer and signal transduction. To treat male pattern baldness, it regulates the expression of growth factors in dermal papilla cells.
Сopper Peptides
Copper Peptides have two main properties as 1) potently protective anti-inflammatory agents that limit oxidative damage after tissue injury, and 2) as tissue remodeling agents. Several studies conducted by research institutes found that copper peptides improved hair transplant success, increased hair follicle size, stimulated hair growth, and reduced hair loss.
Retinoids promote hair regrowth by developing new epithelial cells and improving scalp condition. Topical retinol increases blood flow to follicles and encourages new vessel formation.
Taurine is the body’s most abundant amino acid. It helps promote keratin production, which makes hair stronger and helps stop premature hair loss.
Shea Butter
Rich in vitamins A and E and essential fatty acids, the properties of this extract include anti-inflammation to mitigate damage, collagen support to minimize aging, and moisturizing to reduce frizz.
Candellila Wax
The candelilla plant produces a natural, nutrient-rich butter, absorbed easily, that strengthens the protective barrier function of scalp to retain endogenous moisture and promote hair growth.
Nanodome advanced
Advanced Nanosome Delivery System encapsulates key active ingredients and delivers them to the scalp and skin for a prolonged release and higher efficacy.
