What it does
- Conditions hair and adds body, volume and manageability.
- Forms a light film that improves moisture retention and shine.
- A vegan alternative to animal-derived proteins.
How it works
Hydrolyzed wheat protein consists of water-soluble peptides that deposit on the hair and skin surface, widely documented to improve conditioning, film-forming moisture retention and a fuller feel. It is supplied as a dilute solution, so the use level refers to that material.
Use level
- Typical use level
- typically 1–5% of the (dilute) solution
Commonly used at 1–5% of the supplied (dilute) solution; follow the supplier's guidance.
Formulation considerations
- Water-soluble; add to the cool-down phase.
- Balance proteins with conditioning agents to avoid a stiff feel.
- Vegan alternative to keratin/silk proteins.
What it pairs with & what to avoid
Pairs well with
- Panthenol and conditioning agents
- Humectants and hair oils
Use with care / avoid
- Protein overload (stiff feel)
- Gluten-sensitivity positioning considerations
Regulatory status
Hydrolyzed wheat protein is listed in the EU CosIng database and is a well-established hair-care ingredient.
