Q: How do you determine if you are protein sensitive?
A: If your hair feels hard or dry (strawlike) after using something with protein, that is often a sign of protein overdose (similar to how hair feels after a very strong PT, then you need to DC). People who are protein sensitive get this feeling easier/quicker than those who are not, and their hair often feels like this even when it is wet. For instance, I do not use protein products daily, because after a few days my hair feels gross, while someone who is not PS may use light protein daily with no issues. If I use a protein conditioner on my hair sometimes, it will instantly feel like straw, nothing like a conditioner should feel. Low porosity and coarse hair are also more prone to protein sensitivity.
