How Formula 01 was built

Drag through every stage, from the first draft to the bottle you can buy today.

Every decision, in order
STAGE1
58 actives

Testing 58 actives as partners for 2-DDR exposed the limits of conventional formulation.

Every active was graded on its evidence, including its true delivered yield. The finding: the failures were architecture, not chemistry. 58 actives became 35.

Incompatible chemical classes were separated into dedicated delivery systems, then tested.

2-DDR was pulled out and isolated in its own delivery system, built on an alginate gel.

Formulation review extended beyond the primary actives to every solvent, surfactant and stabilizer. Comedogenic esters, sensitizing surfactants and polymers prone to flaking in daily leave-ons were removed.

2-DDR in alginate, joined only by actives at established levels, and nothing that fights the gel.

One final adjustment, set by bench testing, before the formula was frozen.

Formula 01 is available now. Formulas 02–05 each get their own bottle, built the same way: one decision at a time.

Stage 1 of 8

58 actives, one bottle

Went in

  • He Shou Wu (Polygonum multiflorum)
    Added from its traditional use.
  • A lipid carrier system
    Added for slow release. It could never be made consistently.

Came out or moved

  • Adenosine at more than double its usual level
    Brought back down to 0.75%. More is not better.
Stage 2 of 8

The evidence audit: 58 actives down to 35

Went in

Nothing added at this stage.

Came out or moved

  • He Shou Wu
    Little support beyond traditional use, and a risk of irritation.
  • Kaempferol
    Too little of it made it into the bottle to matter.
  • Soy lecithin
    It was quietly weakening the preservative.
  • Adenosine in a liposome
    Adenosine works in a plain water-based gel. It never needed a special carrier.
Stage 3 of 8

Split by chemistry into separate bottles

Went in

  • A separate bottle for copper ingredients
    Copper ingredients need their own environment, away from ingredients that break them down.
    Formula 03

Came out or moved

  • Vitamin C next to copper
    The two react with each other.
  • Strong mineral binders next to copper
    They pull the copper loose.
Stage 4 of 8

Five separate formulas

Went in

  • Alginate gel
    The base of Formula 01, chosen for 2-DDR.
    Formula 01

Came out or moved

  • 2-DDR
    Moved out of a fast-release gel and into the alginate gel.
    Moved to Formula 01
  • Rinse-off ingredients
    Ingredients that work best rinsed off went to the shampoo.
    Moved to Formula 05
Stage 5 of 8

Closing the gaps: the excipient audit

Went in

  • Melatonin
    Added as an antioxidant partner for 2-DDR.
    Formula 01

Came out or moved

  • Isopropyl myristate
    Known to clog pores. Not something to put near the scalp.
    Formulas 02–05
  • Cocamidopropyl betaine
    A known skin allergen. We accepted less foam.
    Formula 05
  • Rosemary essential oil
    Scent and skin-sensitivity risk.
    Formulas 02–05
Stage 6 of 8

Formula 01 is built and frozen

Went in

  • Adenosine 0.75% + caffeine 1.5%
    Chosen as a pair, at established cosmetic levels.
  • Niacinamide 3.0% + panthenol 1.0%
    Together with adenosine, a well-known trio.
  • Melatonin set at 0.10%
    Raised 30-fold to its established level.
  • Sodium phytate
    Keeps stray minerals from stiffening the gel and supports the preservative.

Came out or moved

  • Zinc
    It would break down the alginate gel.
  • No peptides kept
    They brown when mixed with 2-DDR.
  • 2-DDR at 5%
    More is not better. 2.5% was chosen.
  • Caffeine above 1.5%
    No reason to go higher.
  • Pentylene glycol
    It competes with the gel for water.
  • Popular branded hair actives
    Each one clashed with the gel or the preservative.
Stage 7 of 8

The last change: a stronger gel

Went in

  • Alginate doubled
    Set by bench testing for the right texture on a dry scalp. Formula 01’s final change.
    Formula 01

Came out or moved

Nothing removed at this stage.
Stage 8 of 8

Formula 01 today. Four more to come.

Went in

  • Formula 01
    2.5% 2-DDR plus five supporting actives, each at a stated level, in a weightless alginate gel.

The system

One product. One part of a larger approach.

Hair appearance is commonly discussed as a single concern. In reality, how hair looks and feels depends on several factors, from scalp condition to fiber strength. SYNERGY45 was built as a multi-product cosmetic system so that different products can address different aspects of scalp condition and hair appearance.

Formula 01 is available first. Formulas 02–05 will follow as each completes its own testing and preparation.
