How does Precision Dutasteride work?

Precision Dutasteride is our 0.3% topical dutasteride formulation. It uses the advanced follicular-targeting vehicle developed through a two-year research collaboration with the University of Brasília. Dutasteride inhibits both Type I and Type II 5-alpha reductase enzymes, the key catalysts responsible for converting testosterone into dihydrotestosterone (DHT), a hormone linked to follicular miniaturization and progressive hair loss.

What are the potential side effects of Precision Dutasteride?

While Precision Dutasteride is formulated to reduce systemic absorption, common systemic side effects associated with topical dutasteride include decreased libido, erectile dysfunction, ejaculation disorder, and initial hair shedding. Topical side effects include skin irritation, dryness, redness, and itching.

Who should not use Precision Dutasteride?

This medication is for men only. Women, particularly those who are pregnant or may become pregnant or are breast feeding, should avoid this formulation, as it could harm a developing fetus.

How do I use Precision Dutasteride?

Apply 1ml daily of Precision Dutasteride serum by massaging it gently into the scalp for optimal absorption. Store at room temperature, away from light and moisture. Avoid extreme heat and freezing.

What is the FDA approval status of Precision Dutasteride?

FDA Approval Status: This compounded formulation is not FDA-approved for treating androgenetic alopecia, though it is customized based on emerging clinical research to meet individual patient needs.

Why it works

We fixed the dutasteride delivery problem

Dutasteride blocks the enzymes that turn testosterone into the DHT behind hair loss. Topical treatments aim to concentrate that power at the follicle, skipping the systemic exposure of an oral drug.

But dutasteride penetrates scalp skin poorly, and standard formulas spread it across the surface or toward circulation instead of building a follicular reservoir, which reduces efficacy and raises the likelihood of side effects.

We screened over 60 delivery systems and chose the vehicle that puts 36% more dutasteride at the follicle than the next-best alternative, about twice the mineral-oil control. More of the drug goes where it is meant to work, with less in circulation.
