We Built the Product We Couldn't Find

When GLP-1 medications changed the weight loss landscape, millions of women experienced an unexpected side effect. We built the first topical protocol specifically for them.

The Problem No One Was Solving

GLP-1 medications like semaglutide and tirzepatide have helped millions of people lose weight. But up to 25-33% of women on these medications experience significant hair shedding — a side effect that catches most people completely off guard.

They search for solutions. What they find are generic biotin supplements, hair gummies designed for genetic thinning, and doctors who can only say "wait it out."

None of these were designed for what's actually happening: rapid metabolic change triggering a massive telogen shift, with nutrient depletion making recovery harder.

Our Approach

Provant Labs was founded on one premise: if the problem happens at the follicle, the solution should go to the follicle.

We assembled a formulation advisory board of dermatologists and peptide researchers. We reviewed over 40 published clinical studies on hair follicle biology, telogen effluvium, and topical peptide delivery. We identified five bioactive peptides with published evidence for supporting hair follicle health.

The result: the PD-5 Complex™ — a topical peptide serum that delivers active ingredients directly to the scalp, bypassing the gut entirely.
