Blow-outs after blow-drying, unruly tangle-prone locks, course hair: there are no two ways about it, your hair is porous. You need a big-hitting treatment to get your hair back into tip-top condition fast!
Hair becomes porous when its cuticles, which form a protective barrier around it, are lifted up so much that they absorb moisture but do not retain it. Conversely, non-porous hair has cuticles which are firmly closed. To wash hair that's distressed like this, go for a mild hydrating shampoo which cleanses without aggravating your locks, even with daily use.
To deeply regenerate your very dry and brittle locks, you can count on a formulation high in keratin. This protein made by the hair itself is an active ingredient like no other for filling in fissures in the hair fibre. Used as a hair mask, it pampers and boosts the hair fibre instantly.
Porous hair finds it hard to benefit from the treatments lavished onto it due to its lifted cuticles which allow keratin, water and nutrients to escape again. To resolve this issue, rinse your hair in cider vinegar, whose acidity will smooth down the cuticles, locking moisture in the core of the hair fibre.
So as not to ruin all your hard work, use plant oils which restore the hair's hydrolipidic film and will help your locks benefit from any treatments you apply. They can be used as a leave-in emulsion applied after washing, like Bi-Phase Shine and Soft spray, or as an oil soak for those who have more time to spare.
