Hair Porosity Architect™: The Secret to Hydrated, Frizz Free Hair

If you have ever followed a viral hair routine only to find your strands feel greasy or remain stubbornly dry, you likely have a porosity mismatch. Most shoppers focus on hair "type" (curly vs. straight), but the real key to a successful routine is understanding how your hair cuticles absorise and retain moisture.

Use my Hair Porosity Architect™ tool below to identify your hair’s structural needs and discover the exact product weights, from lightweight milks to heavy butters, that will actually work for you.

Safety & Usage Note

This tool is for educational purposes to help you customise your home hair care routine. If you are experiencing sudden, extreme hair loss or scalp irritation, please consult a trichologist or medical professional. Always patch test new intensive treatments, especially those containing high concentrations of protein.

Why Porosity is the Key to Your Best Hair Day
Most of us choose products based on "damage" or "curls," but porosity is the structural blueprint of your hair. It dictates how the cuticle, the protective outer layer of your hair, behaves.

Low Porosity: The Resistance
If you have low porosity hair, your cuticles are tightly packed like shingles on a roof. This makes it incredibly difficult for water and treatments to penetrate. You may notice that hair products seem to "bead up" on the surface or that your hair takes an age to air dry. To manage this, browse the Look Fantastic promo offers for lightweight, water based hydrators that won't sit on top of the strand.

High Porosity: The Sieve
High porosity hair is often the result of chemical processing, heat styling, or genetics. The cuticles are raised or missing, leaving "gaps" in the hair shaft. While your hair "drinks" moisture instantly, it cannot hold onto it. Without the right sealants, your hair will quickly become dry and frizzy. You should prioritise occlusive butters and protein rich masks found in the Sephora UK offers section to help reinforce the structure.

Frequently Asked Questions

Can I change my hair porosity?
‍While genetics play a huge part, your porosity can change over time. Over processing with bleach or excessive heat can turn healthy, medium porosity hair into high porosity hair. You cannot "repair" the cuticle permanently, but you can neutralise the effects by using the correct product weights found in our Hair Porosity Architect™.

What is the "Glass of Water" test?
‍You may have seen the test where you drop a strand of hair into a glass of water. If it sinks, it's high porosity; if it floats, it's low. However, this is often inaccurate due to surface tension or product residue on the hair. Our diagnostic tool provides a much more reliable result by analysing how your hair behaves during the cleansing and drying process.

Does porosity affect hair colour?
‍Absolutely. High porosity hair absorbs dye very quickly but loses it just as fast (leading to "fading"). Low porosity hair is often "resistant" to colour, meaning you might need longer processing times to get the dye to take.
