Hair follicles are sensitive to nutrient shortfalls — biotin, collagen and key vitamins have each been studied for their role in supporting normal hair structure. Proco's hair essentials are dosed to the same amounts used in those trials, every ingredient on the label.
Common questions
Will this regrow my hair?
Proco's hair essentials are formulated with nutrients studied for their role in supporting normal hair structure and growth — they're not a treatment for hair loss conditions, and results vary person to person. If you're experiencing significant hair loss, talk to a doctor or dermatologist.
What's in these products?
Every ingredient is dosed to published human-trial ranges, with nothing hidden behind a "proprietary blend." Full ingredient panels are on each product page.
How long before I notice a difference?
Hair growth cycles are slow — most trials measuring nutrient effects on hair track participants over 3–6 months of consistent daily use.
Are Proco supplements safe?
Every product is dosed to published human-trial ranges, made in GMP/HACCP-certified facilities and batch-tested with a Certificate of Analysis. If you're pregnant, nursing or taking medication, check with your clinician first.
