HUMIDITY & FLYAWAYS
Hair frizzes when the cuticle lifts and air moves in — in dry rooms, in humid ones, out of the shower, almost always after heat. The fix is rarely more product; it is sealing what is already there in the right order.
THE SCIENCE
Pulls moisture from the air into the shaft. Great in damp climates, unhelpful in desert-dry rooms — check where you actually live.
Fills the micro-gaps in damaged cuticles so they lie flat again. Look for it mid-ingredient list, not last.
Unfashionable but effective: a thin film that blocks humidity from inflating the shaft. Clarify weekly so it does not pile up.
Lightweight, oleic-rich sealing for fine-to-medium hair. Apply to soaking-wet ends, never to dry frizz after styling.

DO THIS TONIGHT
Condition in the shower, then rinse with the coldest water you can stand.
Apply leave-in to soaking-wet hair — within three minutes of the towel.
Never brush dry curls; it breaks the cast and re-lifts the cuticle.
Finish styling with a cool-air pass to set the cuticle down.
STRAIGHT ANSWERS
Cold air holds less water, indoor heating dries it further, and static lifts the cuticle. A heavier sealant and a leave-in stop the static before it starts.
Split ends cannot be repaired — they can only be trimmed. Everything above them responds to hydration and sealing; book a cut every 8–10 weeks to stop it travelling up.
