Dry & damaged hair

Hair is dead. That is not a pessimistic framing, it is the whole reason nothing you buy can repair it. Everything below the scalp is protein and keratin with no blood supply and no ability to heal. What products can do is coat, smooth and slow further damage, and that is genuinely worth doing. What they cannot do is undo.

What's actually going on: the cuticle is a layer of overlapping scales protecting the cortex inside. Heat, bleach, sun, chlorine, hard water and mechanical friction lift and chip those scales. Once enough are gone, the cortex is exposed, water leaves, and hair becomes rough, dull and prone to snapping mid-strand.

Tier 1, dry but intact: condition every wash → focus mid-length to ends, never the scalp → rinse in cooler water → detangle wet with conditioner still in, from the ends upward. Air dry when you can. Two weeks of this is often the whole fix.

Tier 2, rough and breaking: add a weekly mask, use heat protectant every time without exception, and drop your straightener down a setting. Most people use far more heat than they need. Sleep on a smoother pillowcase or braid loosely, because a night of friction undoes a day of care. Give it eight weeks.

Tier 3, snapping when wet, gummy, or stretching: this is structural damage, usually from bleach or a chemical treatment. Cut it. Nothing rebuilds a cortex, and continuing to treat it wastes months. A trim every eight to ten weeks while it grows out is the fastest route to hair you like.

Honest expectations: texture improves in two to four weeks. Damage does not reverse. Hair grows roughly a centimetre a month, so a bleached mid-length will take the better part of a year to leave your head, and every product in between is buying you time and smoothness, not repair.

Watch out for: the word repair on packaging. It is unregulated and means nothing specific. Watch out too for hard water, which coats hair in minerals and makes everything feel worse, and for the assumption that expensive means gentler. A cheap conditioner used every wash beats an expensive mask used monthly.

Plays well with: silicones, which smooth the lifted cuticle better than anything else at the price, panthenol for flexibility, and squalane as a light finishing oil that does not sit greasy.

If hair is breaking close to the scalp rather than at the ends, that is not damage from styling and it is worth seeing someone about.
