Whereas low porosity hair needs lightweight products that won't cause buildups, Bailey explains that for high porosity hair, "It is best to use products that pack a punch with moisture." In that vein, she advises, "I always use a leave-in conditioner on the hair as a layer prior to applying any styling products on the hair."
Other maintenance of this hair type revolves around combatting dryness and ensuing breakage. Bailey says, "I encourage regular cuts and trims, using a moisturizing and reparative shampoo, followed by a moisturizing conditioner."
Because of this emphasis on moisture, those with high porosity hair should also avoid products with harsh ingredients. Bailey suggest steering clear of haircare formulas with alcohol and sulfates, and recommends using clarifying shampoos in great moderation, if at all.
