PROTEIN
Hydrolyzed Wheat Protein/Pvp Crosspolymer
- protein
A synthetic film-forming polymer. Polymers of this kind dry to a continuous film on the hair, which is how a styling product holds a shape.

At a glance
Four named levels, read from this ingredient’s chemical class, its charge, its solubility, or where it sits on the labels we have. More dots means more of the property named — never “better”.
How much of it is left on hair between washes.
What it takes to get it off the hair again.
Smaller fragments travel further into the strand.
Read from where it sits on the labels we have, not from the molecule.

What it does for a formula
What Hydrolyzed Wheat Protein/Pvp Crosspolymer does
The general function first, then how the role changes by product type where we have researched it.
Sticks to damaged areas of the surface and temporarily firms them.
Welcome on limp or damaged hair, unwelcome on hair that already feels rigid.
Fragments small enough to attach to worn areas of the strand — the protein that works.
The film is what holds a shape once the water has gone.
Charge
Charge is not recorded for this ingredient.
Solubility
Spreads through water without truly dissolving, and normal shampooing removes it.

How to read this
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order.
So position tells you about relative amount only above that line, and we never convert a position into a percentage.
Who should pay attention
Conditional formulation guidance, scoped to a hair condition and to the positions where it is meaningful. It is not a conclusion about any finished product, and not a conclusion about you.
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
Hair that reliably stiffens after protein reacts to a prominent hydrolysed protein first; near the top of a list is where it is most likely to be felt.
Read where it is listed in the first three ingredients or positions 4–8.Read from this ingredient’s chemical class. Where we have researched the ingredient itself, that reading replaces the class one.
Why it matters to shoppers
What this ingredient is evidence of, what it is not evidence of, and what our own method can and cannot tell you.
- temporary strength on damaged hair
- a protein that binds to damaged hair
- a style that holds
- a product ordinary shampooing removes
- an exact safety score — we do not publish one, for any ingredient
- how a finished product performs by itself — that is the whole formula, not one line of it
- the exact percentage in a bottle — label position never converts into a number
- a secondary protein, listed below the main ingredients in our styling gels
- it was on the label of every product we counted — we read printed ingredient lists, not marketing copy
- that it repairs hair permanently
- stiffness — only how much of it there is does that
- that a product is right or wrong for you
We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.

These ingredients tend to appear together to firm up damaged areas, improve feel after rinsing, and carry the formula and let it dry.

How this page was made
- Every number above is counted from the ingredient lists in our own product library — 7 of 3889 researched products list this ingredient. Nothing on this page is written per ingredient.
- The dots are named levels read from an ingredient’s chemical class, charge, solubility, or where it sits on the labels we have — never a score.
- US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Position tells you about relative amount only above that line, and we never convert a position into a percentage.
- The prominence bands (leading, supporting, secondary) are the same ones the product pages use to read a single label, applied here to the median position across a category.
- We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.
- Identifiers and references appear only when a published source is attached to this entry; where none is, the row is simply absent rather than filled in.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
