Dew Point Math for Humectants
Dew Point Math for Humectants. We’ll cut through hype and show you what reliably moves the needle.
Your best routine is boring in a good way—same steps, small tweaks for climate and porosity, and predictable results.
Steps
- Dry hands-off; break the cast only when fully dry
- Apply leave-in on soaking-wet hair
- Detangle with water + conditioner in sections
Toolkit
- Microfiber towel or T-shirt
- Wide-tooth comb or flexible brush
- Deep conditioner/mask (monthly)
- Satin/silk pillowcase or bonnet
- Hard-hold gel or mousse for humidity
“Balance humectants with film-formers when dew points rise.”
Example
For winter: reduce humectants, use richer emollients, and seal ends lightly; diffuse on low heat to avoid damp frizz.
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
- High porosity: seal ends; more frequent masks
FAQ
Do I need protein weekly? Only if hair feels overly soft/stretchy; otherwise rotate monthly.
How long to deep condition? 10–20 minutes under a cap is usually enough.
