Porosity is not always visible, but you can feel it when you work the hair. Recognizing it helps you choose the treatment and anticipate how the fiber will respond to products.
What signs does porous hair show?
It usually feels rough and looks dull, frizzy, or lacking shine. In the salon you may notice it absorbs water and product quickly but soon loses that hydration. It can also take color unevenly.
Why does hair become porous?
Brulier's manuals link fiber deterioration to chemical processes, heat sources, and external aggressors. The Carbon manual describes how, once its structure is compromised, hair becomes fragile, porous, and dull.
How do you assess it during the consultation?
Run your fingers along a strand from ends to root and compare the feel of the length with the area near the root. Watch how it behaves when wet and while drying, and ask about recent chemical services. This is a guiding read, confirmed by professional experience.
Which line should you offer for each case?
Dry and porous: Diamond helps correct porosity and distribute hydration better.
Damaged and porous: Golden Protocol 01 is indicated for dry, porous, dull hair, and Protocol 02 for extremely damaged hair.
Which Diamond actives help?
Hydrolyzed wheat protein helps reduce porosity and stabilizes the structure so hydration can spread. Hyaluronic acid works on water retention, and dendê oil forms a protective layer that reduces water loss.
In summary
A rough feel, dullness, and hydration that does not last are common signs of porosity. Confirm during the consultation and work with Diamond or Golden depending on the level of damage.
