Your hair isn't "dry." It's stripped.
When hair feels like straw, the instinct is to reach for "moisture." But dryness is the symptom, not the cause.
Every strand is wrapped in a cuticle — a layer of tiny overlapping scales, like tiles on a roof. When that cuticle lies flat and sealed, hair feels smooth and catches the light. Colour, bleach, hot tools — and if you live anywhere in this country, relentless sun, hard water and humidity — all do the same thing: they lift those scales, strip out the protein and moisture underneath, and leave the surface rough, cracked and porous.
That's why damaged hair tangles, frizzes, snaps, and drinks up product without ever actually feeling better. It isn't thirsty. It's stripped and unsealed. And every wash with the wrong thing strips it a little further.
Once you see the real problem, everything else on this list makes sense.
