And unless you know your hair is lacking protein (more on this later), stay away from protein treatments that can make your hair feel dry and stiff. Instead, leave oils and conditioners in a little longer to give your hair more time to absorb moisture. Don't over-apply product or be heavy-handed. This could be why your hair feels dry! Use heat when applying moisture (steam, warm water, or a heat cap) to open your cuticles. If you have low porosity hair, your hair has a tight cuticle layer and struggles to take in moisture.Since porosity affects how your hair retains moisture, it also affects how you should moisturize your hair.
