How to apply Formula 01
1. Dry the scalp
Water left on the scalp dilutes the gel.
2. 1–2 pumps
Hairline, temples, roots, and crown. Not the hair length.
3. Spread
Work it into a thin film. Do not rinse.
4. Leave it on
Until the next shower, usually 12–24 hours.
A simple 90-day routine
Once a day, on a dry scalp. A routine plan, not a promised result.
- Days 1–30
Build the habit
1–2 pumps on a clean, dry scalp. Leave it on. Take a day-1 photo.
- Days 31–60
Stay consistent
Same time, same amount. Take a photo in the same light.
- Days 61–90
Compare
Set your latest photo beside day 1 and judge for yourself.
A 60 mL bottle often lasts one to two months, so a 90-day routine usually takes more than one.

What’s inside
Six actives at stated levels, in a fragrance-free alginate gel base. What each ingredient is, and its job in the formula, is on the Formula 01 ingredients page.
Key characteristics
- A thick alginate gel, by design. It spreads into a thin film on the scalp and stays there until your next wash, instead of running onto the hair.
- Clean alginate gel. No sodium chloride, zinc, or copper salts are added. A chelator is included specifically to protect the gel from stray calcium and magnesium.
- Adenosine at exactly 0.75%. The level matches established use in hair-care products and was chosen deliberately, not rounded up for a label claim.
- Sodium phytate at 0.10%. It protects the alginate gel and supports the preservative system.
- Visibly improves hair volume, body, and fullness from the root. The gel sets into a light film at the roots instead of weighing them down.
- Promotes the appearance of stronger-looking, more resilient strands. Panthenol and niacinamide condition the scalp and the hair at the root.
- Small-batch, precision-formulated. Two years of organic chemistry and applied biology work and 45 reformulations went into this formula.
- Six actives at stated, deliberately chosen cosmetic-use levels. No token doses.
- Fragrance-free.
- Designed for once-daily use on dry scalp after showering.
- Honest limits: Formula 01 is new, and every claim we make is cosmetic. What we do and don’t claim
How to use
The four steps are above: dry the scalp, 1–2 pumps to desired areas (hairline, temples, roots, crown), spread, and leave it on.

Questions before you buy
Is Formula 01 fragrance-free?
Yes. Formula 01 is fragrance-free: no fragrance or perfume is added. It is a high-concentration 2dDR cosmetic scalp serum, 2.5% 2-deoxy-D-ribose with five supporting actives in an alginate gel, so there is no scent to clash with your styling products. Every ingredient and its job is on the Formula 01 ingredients page.
Designed as part of a system
Formula 01 is the first product released from a five-formula cosmetic architecture. Formulas 02–05 target different aspects of scalp condition and hair appearance. They are intended to be used together as a coordinated regimen rather than as isolated products.
