Porosity 101: Test Methods & Meaning — Deep Dive #2

Porosity 101: Test Methods & Meaning — Deep Dive #2. Here’s a field-tested path you can run for two or three wash days, then decide.

The core idea: fewer, better steps. Cleanse the scalp well, condition until slip, style on soaking-wet hair, then hands-off until dry.

Steps

1. Apply leave-in on soaking-wet hair
2. Layer gel/foam; rake then scrunch
3. Soak thoroughly before applying anything

Toolkit

• Satin/silk pillowcase or bonnet
• Hard-hold gel or mousse for humidity
• Deep conditioner/mask (monthly)
• Microfiber towel or T-shirt
• Wide-tooth comb or flexible brush
• Chelating/clarifying shampoo (as needed)

“Hands-off until fully dry is half the battle.”

Example

For workouts: quick refresh—mist water + a touch of leave-in at the hairline and crown.

Science angle: porosity governs water movement; humectants pull moisture; film-formers create a cast; proteins patch weak spots temporarily.

Porosity & Climate Notes

• Humidity: pair humectants with film-formers
• Low porosity: lighter layers; avoid heavy oils
• High porosity: seal ends; more frequent masks
