Collagen for hair
Hair itself is made of keratin — but every follicle grows in a collagen-rich connective tissue that nourishes and protects it. Collagen supplies the amino acids for its build. Nails benefit in the same way. Here's how collagen strengthens hair and nails from within.
Key facts at a glance
Hair is made of keratin, but the root sits in the collagen-rich dermis — without intact connective tissue the follicle lacks its foundation. Collagen peptides supply proline and other amino acids for keratin formation. The evidence is clearest for nails: fewer breaks and faster growth after 24 weeks (Hexsel et al., 2017).

Why strong hair needs healthy collagen.
The visible hair is dead keratin — what's alive is the hair root in the follicle, deep in the dermis. This skin layer is largely collagen and surrounds each follicle with connective tissue that supplies nutrients and mechanical support. When the dermis' collagen density falls — with age or through oxidative stress — the environment in which hair grows deteriorates.
Collagen provides the body with proline and glycine, key building blocks for the keratin of hair and nails. The evidence is clearest for nails: in a clinical study with 2'500 mg of collagen peptides a day, the frequency of brittle nails fell by 42 % after 24 weeks and nail growth rose by 12 % (Hexsel et al., 2017).
What matters for collagen for hair and nails.
Whether collagen truly supports hair and nails comes down to three factors — they decide the dose, the absorption and how easily you keep it up.
A sufficient dose
The nail studies use around 2'500 mg of collagen peptides per day; for skin and connective tissue, more is better. One daily dose of Pro-Active delivers 10'000 mg — well above the study dose.
Hydrolysed & bioavailable
Only hydrolysed peptides travel via the bloodstream into the dermis where the follicles sit. A ready-to-drink shot delivers the full daily dose without mixing.
Consistent intake
Hair and nails grow slowly. The nail study showed effects over 24 weeks — a ready-to-drink shot makes daily intake over months effortless.

Collagen for hair — your questions
Does collagen really help hair growth?
Collagen is not a direct hair-growth agent, but it creates the foundation: it supplies the amino acids for keratin and supports the connective tissue the follicles sit in. The clearest evidence is for nails — more firmness and faster growth.
Is collagen good for nails?
Yes, this is where the evidence is strongest. In a clinical study, the frequency of brittle nails fell by 42 % after 24 weeks of daily collagen peptides and nail growth rose by 12 % (Hexsel et al., 2017).
How much collagen for hair and nails per day?
The nail studies use around 2'500 mg of collagen peptides daily. Collagen Pro-Active Advanced delivers 10'000 mg in a ready-to-drink 25 ml daily dose — the building blocks for hair, nails and connective tissue at once.
Do I also need biotin?
Biotin and zinc are proven to contribute to normal hair and nails. Collagen Pro-Active Advanced already contains both, so you combine collagen and these micronutrients in one product.
When will I see first results?
Many users notice firmer nails after 4 to 8 weeks. Since hair and nails grow slowly, studies recommend consistent intake for at least 12 to 24 weeks.
