Low Porosity · Routine Guide
Low porosity hair isn't difficult — it just refuses to play by the same rules as everyone else's. Here is a routine built for the way your cuticle actually behaves.

The Basics
Rules of Thumb
What to Reach For
Used every 4 to 6 weeks to remove buildup that low porosity hair accumulates quickly. Without clarifying, your other products simply won't penetrate.
Look for thin, water-based conditioners that rinse clean. Heavy, butter-based conditioners often coat low porosity hair without delivering moisture.
Choose deep conditioners with smaller-molecule humectants and emollients. Apply to damp hair, then use indirect heat for 15–30 minutes.
A spray or thin cream leave-in absorbs better than a thick lotion. The first ingredient should be water or aloe.
Argan, grapeseed, jojoba, or fractionated coconut oil seal moisture without weighing low porosity hair down. Use sparingly on the ends.
Step-by-Step
Step 1
Apply a lightweight oil or conditioner to dry hair, cover with a warm towel for 15–20 minutes. Heat gently lifts the cuticle so the wash that follows can actually clean and condition.
Step 2
Use a clarifying shampoo every 4–6 weeks; a moisturizing sulfate-free cleanser between. Focus the cleanser on the scalp.
Step 3
Warm water keeps the cuticle relaxed and open through the rinse. Skip the cold rinse here — it seals the cuticle before product goes in.
Step 4
Apply deep conditioner to damp hair. Use a steamer, hooded dryer, or plastic cap with a warm towel for 15–30 minutes.
Step 5
Section the hair, mist with a water-based leave-in spray, then apply a thin cream. Smaller amounts in more sections beat globs in fewer.
Step 6
Use a light oil only on the bottom inch or two. Sealing the entire length traps water — but on low porosity hair, often traps it on the outside.
Step 7
Air-dry or diffuse on low. Sleep on satin or silk to reduce friction and protect the moisture you just locked in.

Low porosity hair often looks healthy and shiny because the cuticle lies flat. The catch: products tend to sit on the surface rather than absorbing, which can leave the hair feeling coated, weighed down, or perpetually under-moisturized despite a packed shelf.
Most low porosity hair does well with a wash every 7 to 10 days, paired with a clarifying wash every 4 to 6 weeks to remove buildup. Because product struggles to absorb, residue accumulates faster than people expect — clarifying on a schedule keeps the cuticle accessible.
Indirect heat — like a steamer, hooded dryer, or warm towel — during deep conditioning is one of the most effective tools for low porosity hair, because it gently lifts the cuticle so moisture can enter. Direct high heat from flat irons and blow dryers should still be used sparingly.
Heavy butters, thick oils (like castor oil applied throughout the hair), and protein-heavy products used too frequently can all sit on top of low porosity strands and cause buildup. This does not mean never — it means use sparingly and watch how your hair responds.
The clearest way to confirm is a behavior-based hair porosity quiz. Take the free 2-minute Hair Porosity Test to see if your hair behaviors match low, medium, or high porosity — and get a routine built for whichever one is yours.
