Hair Care Routine for High Porosity Hair

High porosity hair has cuticle layers that are raised, gapped, or damaged — meaning it absorbs moisture extremely quickly but loses it just as fast. The result is hair that drinks up product but still feels dry an hour later, frizzes at the slightest humidity, and tangles easily. High porosity can be genetic, but it is more commonly caused by heat damage, chemical processing (bleach, relaxers, color), environmental wear, or rough mechanical handling. The repair strategy focuses on two things: filling in the gaps in the cuticle and sealing moisture once it is absorbed. Rich, heavy products that would weigh down low porosity hair are exactly what high porosity hair needs — thick leave-in conditioners, protein treatments to fill gaps in the strand, butter and oil sealants to close the cuticle, and regular deep conditioning to maintain hydration. Cold water rinses after conditioning also help flatten the cuticle and lock moisture in longer.
