Most brands sell one detangling brush and hope. Olivia Garden's CurlyHair line is built the other way round: the bristle spacing and height change with the curl pattern, and each product states the curl-type range it is for. That makes choosing genuinely easy — once you know your number.
Find your curl type in thirty seconds
Look at clean, air-dried hair with no product in it.
- 2A — loose S-waves you can almost brush out. Falls flat easily.
- 2B — defined S-waves starting at mid-length, some frizz at the crown.
- 2C — waves that start at the root, a few actual spiral curls mixed in, frizz-prone.
- 3A — loose spirals roughly the diameter of a piece of sidewalk chalk.
- 3B — springy ringlets about the diameter of a marker pen.
- 3C — tight corkscrews about the diameter of a pencil, densely packed.
- 4A — defined coils about the diameter of a crochet needle.
- 4B — hair that bends in sharp Z angles rather than curling.
- 4C — tightly packed coils with little visible definition and the most shrinkage.
If you are between two, size up to the wider-spaced tool. A tool that is too wide is merely slow; a tool that is too narrow pulls the curl apart and snaps it.
Match your curl type to the tool
| Curl type | Buy this | Why |
|---|---|---|
| 2A – 3A | CurlyHair Brush (uniform bristles) or CurlyHair Splash Brush, Purple | Uniform bristle height keeps the wave pattern together instead of brushing it into a fluffy halo. Stated range 2A–3A. |
| 2C – 4A | CurlyHair Splash Dual Bristle Brush, Green | Two bristle heights: the long bristles get through the clump, the short ones catch and keep definition. Stated range 2C–4A. |
| 3B – 4C | CurlyHair Wide Bristle Brush or CurlyHair Splash Wide Bristle Brush, Pink | The widest spacing in the range. Anything narrower fights a tight coil pattern. Stated range 3B–4C. |
| All types, wet detangling | CurlyHair Comb & Pick (cone teeth) | Cone-shaped teeth taper into the clump instead of ploughing through it. Doubles as a pick for root volume on dry hair. |
| 3C – 4C, heavy tangles | Wide Tooth Comb with Handle | The widest comb we carry. The handle gives you leverage without a fistful of hair. |
| Fine or fragile curls | iDetangle for Fine Hair | Double silk memory-flex bristles — the bristle gives way before the hair does. |
How to actually detangle curly hair
- Do it wet and slippery. Conditioner still in, or a dedicated detangler. Dry-brushing a curl pattern is the single most damaging thing you can do to it.
- Work bottom-up in sections. Start at the ends, get those clear, then move up two inches at a time. Starting at the root pushes every tangle down into one solid knot at the ends.
- Hold above where you are brushing. Your other hand takes the tension so it does not reach the root.
- Stop when it is clear, not when it is straight. Curly hair that has been brushed straight has lost the clump, and that is where frizz comes from.
- Let it dry undisturbed. Touching a drying curl is the other main frizz source.
What will not help
- A boar-bristle brush. Wonderful on straight hair, wrong here — dense boar drags a curl clump apart. Use boar only if you are deliberately stretching or blowing out.
- A fine-tooth comb. It will find every tangle and rip it. Keep fine-tooth combs for parting and sectioning.
- A round brush at 4A–4C without stretching first. Blow-dry the hair straight with a paddle or comb attachment first, then use the round barrel for shape.
- Brushing dry on a wash-and-go. If you must refresh, mist first.
Beyond detangling: scalp care under curls
Dense curl patterns hide product buildup close to the scalp, and buildup is behind a lot of what gets blamed on dryness. The Scalp Diva brushes handle it — the cleansing brush works shampoo down to the scalp through a dense pattern, the exfoliating brush lifts flake and buildup, and the massage brush is for circulation on dry hair. All three are safe on any curl type because they work the scalp, not the length.
The bottom line
2A–3A: CurlyHair Brush. 2C–4A: the green dual-bristle Splash. 3B–4C: the wide-bristle brush plus the wide-tooth comb with a handle. Detangle wet, bottom-up, with something slippery in the hair, and stop when it is clear rather than when it is straight.
