Does low porosity hair need protein or moisture?

Low porosity hair typically needs more moisture than protein. This is because low porosity hair has a tightly closed cuticle layer, which can make it difficult for moisture to penetrate and be absorbed into the hair shaft. As a result, low porosity hair may feel dry and brittle, despite having a healthy protein structure.

Protein treatments can be beneficial for low porosity hair to help strengthen the hair and prevent breakage, but it is important to use them in moderation. Overusing protein treatments can lead to an imbalance in the hair's moisture-protein balance, which can cause the hair to become stiff, brittle, and prone to breakage.

In general, low porosity hair benefits from regular deep conditioning treatments that focus on adding moisture to the hair. Using lightweight, water-based products that can penetrate the hair cuticle and layer with a light oil or butter sealant can help keep low porosity hair hydrated and healthy.
