Along with hair type and porosity, trichologist Angela Onuoha sees another piece to the hair puzzle. “I wouldn’t focus too much on porosity but rather on how your hair appears and feels,” she says. “Knowing your hair type may aid in the selection of a suitable regimen for your hair requirements. I believe that, together with knowing your hair density (how thick or thin your hair is), this is the most essential information.”

There’s a lot to understand. Understanding my hair porosity has been more helpful than perplexing me in my own hair journey – I now know why my hair gets dried up so fast and can adjust my regimen as needed. With each wash day, I’m getting closer to knowing my head from the inside out.
