If your hair has low porosity, it means your hair bonds are tightly packed and resistant to receiving moisture. If you take the strand test, your hair strand will float on the top due to its incapability to absorb water. This shows that low porosity hair cannot absorb products easily.
1. Use Lightweight products to avoid product sitting on the hair.
2. Clarify the hair to open cuticle and remove product buildup.
3. Use water based moisturizers
4. Deep conditioning treatments after wash, avoid protein treatments until porosity normalizes.
