High Porosity · Routine Guide
High porosity hair drinks moisture in seconds — and loses it nearly as fast. The goal of this routine isn't getting moisture in. It's keeping it there.

The Why
The cuticle is the outermost layer of every hair strand. On low porosity hair, the cuticle scales lie flat and tight. On high porosity hair, those scales are raised, lifted, or chipped — sometimes naturally, sometimes from heat, color, or chemical processing.
Open cuticles let water in instantly. They also let it leave just as easily. That's why your hair can feel completely soaked one minute and dry, frizzy, and thirsty an hour later.
High porosity hair is also more vulnerable in humidity, because the open cuticle absorbs ambient moisture from the air — which is the technical reason behind sudden, no-warning frizz.
Lock It In
Start with a water-based liquid leave-in. Follow with an oil to seal the water against the strand. Finish with a cream to add a final moisturizing layer. This is the most reliable starting point for high porosity hair.
Same idea, different order. Cream goes before the oil. Some high porosity hair holds moisture better this way. Try both — your hair will tell you which feels softer at day three.
Shea butter, mango butter, castor oil, and avocado oil are denser than light oils and physically slow moisture escape. Use them as the sealing layer, not as the moisture itself.
Finish wash day with a cool water rinse to encourage the cuticle to lay flatter. It won't fix high porosity, but it gives your sealing layer a better starting condition.
A diluted ACV rinse (1–2 tablespoons in a cup of water) periodically helps temporarily smooth the cuticle and remove buildup. Use sparingly — once every 2 to 4 weeks.
The Balance
High porosity hair almost always needs more protein than low or medium porosity hair. Protein treatments fill in gaps in the damaged cuticle, temporarily strengthening the strand and helping it retain moisture better.
But too much protein swings the pendulum the other way: hair becomes brittle, stiff, and snaps easily. The fix is alternation.

High porosity hair has open or raised cuticles. That means water and product enter quickly, but they also escape just as quickly because the cuticle can't form a tight seal. The fix is a layered moisture routine paired with a sealing step that physically slows that escape.
The LOC (Liquid, Oil, Cream) and LCO (Liquid, Cream, Oil) methods both work well for high porosity hair. LOC is often preferred because the oil sits between the water and the cream, slowing moisture loss most effectively. The exact order can vary by hair — both are worth trying.
Often yes. High porosity strands have a weakened cuticle structure that benefits from protein treatments to fill in gaps and strengthen the strand. The trick is balance — too much protein leads to brittleness, so alternate protein with deep moisture treatments and watch how your hair responds.
Most high porosity hair benefits from daily light moisturizing — a quick spray of water-based leave-in plus a sealing step. Wash day deep conditioning every 7 days, and a protein treatment every 4 to 6 weeks, is a strong starting cadence.
Take the free 2-minute Hair Porosity Test. It uses behavior questions — how fast your hair dries, how it reacts to humidity, how long moisture lasts — to tell you whether you're high, medium, or low porosity, then builds a routine to match.
