As the seasons shift, so should your hair care. Here's exactly how to adjust your wash day routine for low, medium, and high porosity hair before the cooler months take a toll.
Why Fall Is the #1 Hair Crisis Season
Summer may feel like the culprit — and yes, UV exposure, pool water, and humidity do a number on your strands — but fall is when the real damage shows up. Cooler, drier air pulls moisture from your hair faster than warm, humid air can replenish it. The result? Unexpected dryness, brittleness, excess shedding, and frizz that your summer routine simply can't fix.
The secret to thriving hair this season isn't buying more products. It's understanding your hair porosity — and adjusting accordingly.
What Is Hair Porosity and Why Does It Matter in Fall?
Hair porosity refers to how well your hair absorbs and retains moisture. Your cuticle layer (the outer protective shield of each strand) determines this — and seasonal shifts in temperature and humidity directly affect how it behaves.
- Low porosity hair: Tightly closed cuticles that resist moisture absorption. In fall, product buildup increases and moisture sits on the surface rather than penetrating the strand.
- Medium porosity hair: Balanced cuticles that absorb and retain moisture well — but still need extra hydration support as the air gets drier.
- High porosity hair: Raised or damaged cuticles that absorb moisture quickly but lose it just as fast. Fall's dry air can make high porosity hair feel perpetually parched and prone to breakage.
Your Fall Transition Routine by Porosity Type
Low Porosity Hair: Clarify First, Then Hydrate
Low porosity hair accumulates product buildup faster in cooler months because the cuticle is already resistant to letting things in. Before you can add moisture, you need to open the door.
Step 1 — Clarifying Wash
Start with a gentle but effective shampoo that removes buildup without stripping. GrowPoo Moisturizing Shampoo is ideal — plant-powered to lift buildup while infusing strands with shea butter, pumpkin seed oil, and hemp seed oil. No harsh sulfates, no stripped feeling.
"This is literally my go-to shampoo — she's very low lather but cleanses the scalp without too much strip." — Abriana M., verified buyer
Step 2 — Lightweight Leave-In
After washing, reach for a lightweight leave-in that hydrates without adding weight or contributing to more buildup. Hair Dew Low Porosity Leave-In is a 3-in-1 mist that delivers daily hydration, heat protection, and UV shielding in one effortless spray.
"My 4C curls thrive with the Hair Dew — soft, shiny, and super hydrated!" — Verified buyer
Pro tip for low porosity in fall: Apply your leave-in on warm, damp hair just out of the shower. The warmth helps the cuticle open slightly so moisture can penetrate instead of sitting on top.
Medium Porosity Hair: Maintain Your Routine, Add Moisture
Medium porosity hair handles seasonal transitions better than the other types — but "better" doesn't mean immune. As fall kicks in, your hair will start craving a little more moisture and nourishment than it did in summer.
Step 1 — Keep Your Cleansing Consistent
Don't skip wash day. Stick with your moisturizing shampoo to keep your scalp clean and your strands prepped. GrowPoo Moisturizing Shampoo works beautifully for medium porosity — the botanical blend of green tea and chamomile helps soothe the scalp while panthenol (Pro-Vitamin B5) strengthens and softens.
Step 2 — Condition with Intention
Medium porosity hair benefits from a protein-balanced conditioner that fortifies without overloading. Pair with a leave-in mist to seal hydration in and protect against the elements before you style.
Pro tip for medium porosity in fall: Add a weekly deep conditioning step to your routine if you aren't already doing one. The seasonal dryness is subtle at first — catch it early.
High Porosity Hair: Seal, Seal, Seal
High porosity hair is the most vulnerable in fall. Because the cuticle is already raised or damaged, dry air will pull moisture out of your strands almost immediately after wash day. Your entire fall focus should be on sealing moisture in after every step.
Step 1 — Strengthen at the Wash
GrowPoo Moisturizing Shampoo contains hydrolyzed soy protein and panthenol to help reduce breakage and support strand integrity from the very first step.
"OrganiGrowHairCo has completely healed my hair multiple times. Been supporting since 2018 and will always support!" — Verified buyer
Step 2 — Condition with Protein Support
High porosity hair craves a conditioner that fills in the gaps of the cuticle and supports elasticity. The Condish (Protein) delivers Hemp Protein, Macadamia Butter, and Avocado Oil to fortify strands and make detangling effortless — without leaving hair stiff or overloaded.
Step 3 — Lock in Moisture with a Leave-In
After conditioning, use a leave-in to seal everything in before the fall air can pull it back out. Layer a lightweight mist first, then follow with a butter or cream sealant to keep moisture locked in all day.
Pro tip for high porosity in fall: The LOC method (Liquid → Oil → Cream) is your best friend this season. Apply your leave-in mist, then layer an oil and a cream sealant on top to prevent moisture from escaping.
