However, both parameters must be considered when designing a product. If the concentration in a given formulation is above C*, the product might not be able to be sprayed, so the application will be limited. On the flip side, if the product is sprayed onto the hair but the polymer is not large enough to entangle, the product will be unsuccessful. For a more in-depth study including the physics of these phenomenona, consult Wool’s review.3
