Aqua, Propanediol, Glycerin, Copper Tripeptide-1, Butylene Glycol, Niacinamide, Panthenol, Copper Tripeptide-3, Caffeine, Lecithin, Hydrogenated Lecithin, Dextran, Hydroxyethylcellulose, Zinc PCA, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, Sodium Hyaluronate Crosspolymer, Rosmarinus Officinalis (Rosemary) Leaf Extract, Allantoin, Biotinoyl Tripeptide-1, Ethylhexylglycerin, Potassium Sorbate, Sodium Hydroxide.  
Recommended Usage

Apply a small pea sized amount to your thinning areas. Massage into the scalp for 30 seconds and then let it sit over night. 
Who does this work for?

The serum works for both men and women experiencing hair loss. 
Can I use Alongside Minoxidil?

Yes! If you apply minoxidil before bed, apply this after once the minoxidil has dried.  
Can I use as a standalone product?

Yes. Many people use copper peptides on their own, and BLU Elixir is designed to work as a standalone. For hair loss, a multi-pronged approach is usually best, so it also fits into a routine you already have.

The evidence

The science of our ingredients

The key actives in BLU Elixir, what each one does, and the papers you can read yourself.

Copper Tripeptide‑13%

The primary copper peptide in the formula.

Copper Tripeptide-1 is GHK-Cu, a copper peptide your body already makes. It was first isolated from human plasma in 1973. In lab research it increases collagen, elastin, and glycosaminoglycan production and supports the fibroblasts in the skin around each follicle. That’s the environment your hair grows from.

Copper Tripeptide‑31%

The second copper peptide. 4% copper peptides total.

Copper Tripeptide-3 is AHK-Cu, the copper peptide with the most direct hair data. In a 2007 study, AHK-Cu lengthened human hair follicles grown in the lab and increased dermal papilla cell growth. Dermal papilla cells sit at the base of the follicle and run the growth cycle. The study was done on follicles in culture, not on a scalp.

Hyaluronic Acid

Four molecular weights.

Four molecular weights of hyaluronic acid. Hyaluronic acid is a glycosaminoglycan, the same family of molecules GHK-Cu increases in lab research. Researchers have paired the two directly. Hyaluronic acid bound to GHK improved wound closure over hyaluronic acid alone, and a hyaluronic acid gel carrying copper GHK sped up skin repair with denser collagen.

Niacinamide

Vitamin B3. Studied in the cells that run the hair growth cycle.

Niacinamide is vitamin B3. In dermal papilla cells, the cells that run the hair growth cycle, it lowered DKK-1, a protein that signals follicles to stop growing, and protected the cells from oxidative stress. In a 24 week placebo-controlled trial, a scalp formula containing niacinamide increased crown hair count by 17.76% over placebo.

Caffeine


The cosmetic active tested head to head against minoxidil.

Caffeine is one of the only cosmetic actives tested head to head against minoxidil. In a 6 month trial of 210 men, a 0.2% caffeine liquid improved the ratio of actively growing hairs by 10.59%. 5% minoxidil improved it by 11.68%. Researchers judged caffeine not inferior. In lab work, caffeine also blocked testosterone’s growth-suppressing effect on follicles taken from men with pattern hair loss.

Zinc PCA

Zinc bound to PCA, a moisture binder your skin already makes.

Zinc PCA pairs zinc with PCA, a moisture-binding molecule your skin makes naturally. It’s a staple in scalp and oily-skin formulas. In lab research on skin cells, it reduced UV-triggered collagen breakdown and increased collagen production.

Biotinoyl Tripeptide‑1

The anchoring peptide.

Biotinoyl Tripeptide-1 is biotin (vitamin B7) bound to GHK, the same peptide behind Copper Tripeptide-1. In lab studies on human hair follicles, it concentrated around the base of the follicle, stimulated the cells that build the hair, and helped preserve collagen IV and laminin 5, the proteins that hold the hair in place. That’s where the anchoring name comes from. These results come from follicles in culture, not a scalp trial.
