Brush before the wash, not after. Dry detangling removes shed hair and loosens tangles when the hair is at its strongest, so the wash goes faster and gentler. After the wash, detangle with conditioner and a wide-tooth comb, and save the brush for when the hair is mostly dry.

## Why dry hair handles brushing best

Hair is strongest when dry. Water swells the hair shaft and lifts the cuticle, which makes wet hair stretchier and more fragile: it can stretch up to 30 percent before breaking, and each stretch weakens the fiber a little. Brushing dry hair works with the fiber at full strength, so the same tangles that would snap wet strands slide out dry.

A dry pre-wash brush also removes the day's shed hair before it hits the drain. Most of the hair you see in the shower is hair that was already shed and caught in the rest. Brushing it out dry keeps the drain clearer and makes the wash itself faster, because the shampoo does not have to work through a mat of loose strands.

## The pre-wash routine

Work in sections, starting from the ends and moving up toward the roots. This is the single most important detangling rule: starting at the roots packs every tangle downward into a knot, while starting at the ends clears them progressively. Use a brush with flexible bristles or a detangling brush, not a stiff paddle, and be especially gentle at the crown where hair is thinnest.

If the hair is very tangled, a little oil or a detangling spray on the dry ends gives the brush slip. Five minutes of dry detangling can easily save fifteen minutes of wet detangling, and it saves the breakage that wet detangling causes.

## What to do after the wash instead

After shampooing, do not reach for the brush. Apply conditioner generously and detangle with your fingers or a wide-tooth comb, still working ends to roots. The conditioner gives the slip that water alone does not, and a comb's spaced teeth separate strands without the tension a brush applies.

Rinse, squeeze out excess water with a microfiber towel or a cotton t-shirt, and let the hair get to about 80 percent dry before any brush touches it. If you must brush damp hair, use a vented brush lightly and never force it through a snag: stop, add a little leave-in, and work the tangle out with your fingers first.

## The exceptions

Very curly and coily hair often skips dry brushing entirely, because brushing dry curls disrupts the curl pattern and creates frizz. For these hair types, the rule adapts: detangle on wet, conditioned hair in sections with fingers or a wide-tooth comb, and treat that as the brushing step. The principle is the same, only the timing moves to when conditioner provides the protection.

Fine, straight hair is the opposite case: it benefits most from dry brushing, because it tangles easily and wet fine hair snaps readily. If your hair is fine and straight, the pre-wash brush is the highest-value two minutes of your routine.

## The order that works

Dry brush in sections before the wash, wash, condition and comb with conditioner in, towel dry gently, brush again only when mostly dry. Curly and coily hair moves the detangling to the conditioned step. Follow that order and the brush stops being a breakage tool and goes back to being a styling tool.

## Frequently asked questions

### How often should curly hair be washed?

Most curls thrive on one to two washes a week, adjusted for scalp oiliness, workouts, and product load. The scalp's comfort is the guide: an itchy, flaky scalp wants more washing, not less.

### What does porous hair mean?

Porosity is how easily hair absorbs and loses water. High porosity hair takes up water and product fast and dries fast too, so it needs richer conditioning and gentler handling.
