Collagen

What is Collagen?

A structural protein, sold as powders and capsules.

Key facts at a glance

How it's thought to work

Supplies amino acids — but your body breaks it down like any protein.

What the research says

Skin studies exist; hair studies are scarce.

How it's used

Powder in drinks, daily.

Protein needs and marketing

Collagen is digested into amino acids and peptides; it is not delivered intact to the hair shaft. Hair is primarily keratin. Adequate nutrition matters, but adding collagen when protein intake is sufficient has not been established as a treatment for pattern hair loss.

A fair comparison

Compare supplement cost with ordinary dietary protein and the reason your hair is changing. A collagen powder, a FOLIGAIN® cosmetic product and OTC Minoxidil make different claims and should not be treated as substitutes. Ask about unexplained diffuse shedding before committing to months of supplements.

The good and the not-so-good

A quick, balanced look before you decide whether it belongs in your routine.

What it pairs well with

People often combine ingredients. These combinations are common — check with a pharmacist or doctor if you use prescription products.

• A protein-rich diet

A friendly safety note

This page is general education, not medical advice. Patch-test new topicals, stop if your scalp becomes irritated, and see a doctor or dermatologist for sudden, patchy or painful hair loss. Talk to a professional before starting supplements if you are pregnant, breastfeeding, take medication or have a health condition.
