The wide, contoured brush built for hair the Heart Brush doesn't fully reach, and an honest answer on who should buy the other one instead.
If you have already read Which ReFa Brush Is Best?, you know the AILE BRUSH in outline: wider head, same three-level bristles, built for thicker or longer hair. This is the fuller answer on that one model alone, the questions people actually type before buying it rather than a shared verdict box. If the Heart Brush is the one you are actually deciding on, we cover that separately in our standalone Heart Brush review.
Our shoppers hear the same handful of questions about this brush on every Tokyo trip. Is it actually different from the Heart Brush, or just a bigger version of it? Can it get wet? Does the wider head suit fine hair, or only thick? Here is the plain answer to each, plus where it falls short.
The quick answer
- Thick, long or slow-to-detangle hair: the ReFa AILE BRUSH, this one.
- The classic dressing-table shape, in more colourways: the ReFa HEART BRUSH.
- A routine that starts in the shower: the ION CARE BRUSH PREMIUM, not this brush.
- Fine hair or a rough, tangle-prone texture: the AILE BRUSH RAY's natural bristle finish.
Every AILE BRUSH we carry comes from authorised Tokyo retailers, factory sealed. Runs are limited to what our shoppers bring back each trip, and colourways move at different speeds. If the finish you want is not showing, message Live Chat and we will flag you for the next shipment.
What does the ReFa Aile Brush actually do?
The wide, contoured head is the whole point. Where the Heart Brush sits in the palm as a compact heart, the AILE BRUSH stretches out to follow the curve of the skull, so one stroke gathers a broader section, back layers and inner layers included, instead of the narrower pass a smaller head allows.
Underneath that shape is the same three-level bristle logic ReFa uses across the range. Detangling bristles, taller and set at varied angles, work into a knot from more than one direction and ease it apart rather than dragging through. Shorter polishing bristles follow behind and lay the surface flat, which is where the shine comes from: a roughed-up hair surface scatters light, a smoothed one throws it back in one direction. Every tip is rounded, and the bristles carry an antistatic agent. How much static it actually cuts varies with humidity and the hair's own condition on the day, which is the honest version of that claim rather than a blanket promise.
Is the ReFa Aile Brush waterproof?
Not quite yes, and not quite no. ReFa's own guidance sits in between: the brush can get wet without being ruined, but it is built for detangling and polishing dry hair, and that is what it wants to be used for. If it does get wet, the instruction is straightforward: shake off the water, wipe away what is left, and let it air-dry somewhere shaded and ventilated.
What it is not built for is the shower. ReFa is specific here too, directing shampoo and conditioning use to the ION CARE BRUSH PREMIUM instead. So the honest line is this: a splash will not damage the AILE BRUSH, but a shampoo routine belongs with a different tool entirely. Worth noting because the standard Heart Brush sits at the opposite end of this same question: ReFa states plainly that it is not waterproof and is for dry hair only, no ambiguity there. Two brushes, two different answers, and this is exactly the kind of detail worth checking per model rather than assuming one ReFa brush behaves like another.
Aile Brush or Heart Brush? What's actually different day to day
On a spec sheet the two brushes look nearly identical: three-level bristles, dry-hair use, an antistatic agent. In the hand, the difference is the head. The HEART BRUSH's compact heart shape sits neatly for control, front sections, a fringe, the last brush-through before you leave the house. The AILE BRUSH's wider, flatter head trades some of that precision for coverage, fewer strokes to clear the same amount of hair, and it reaches the back of the head more comfortably than a smaller brush held at an angle.
| AILE BRUSH | HEART BRUSH | |
|---|---|---|
| Shape | Wide, contoured, follows the head | Compact heart, sits in the palm |
| Bristles | Three-level: detangling plus polishing | Three-level, same principle |
| Best use | Broad sections, back and inner layers | Precision, fringe, front sections |
| Wet hair | Can get wet; built for dry-hair use, not the shower | Not waterproof; dry hair only |
| Finish | Four finishes: Rose Gold, Silver, Matte Black, Pearl White | Ten finishes, including the M Collection pastels |
Colourways are the other real difference. The HEART BRUSH runs to ten finishes; the AILE BRUSH keeps to four. If a specific shade matters more than the head shape, that alone can decide it. If your hair is thick or takes a while to get through, the wider head earns its keep every single brush-through, and that is worth more than an extra colour choice. See the full three-way picture, including where the ION CARE BRUSH PREMIUM sits, in Which ReFa Brush Is Best?, and every other tool in the range in Every ReFa Hair Tool, Ranked.
Which hair types does the Aile Brush suit?
Thick, long or slow-to-detangle hair is where this brush earns its shape. The wider head means fewer strokes to clear the same section, which matters most on hair that takes real time to work through. Permed hair is fine too, ReFa's own guidance is to brush it gradually rather than pulling, the same care any permed hair needs regardless of the brush.
Fine hair or a short cut will not get much extra from the wider head, since there is less hair per stroke to justify it, and the compact HEART BRUSH will feel more precise for framing sections. If the texture itself is the issue, tangles easily, feels rough at the ends rather than simply long, the AILE BRUSH RAY is worth a look instead. Same wide shape, a different bristle mix: flexible nylon pins for the tangles, then natural pig bristles for the polish, and it is not waterproof at all, so it sits at the stricter end of the range's water rules rather than the AILE BRUSH's middle ground.
Can you use the ReFa Aile Brush with hair oil?
Yes. Brushing through after hair oil is one of the uses ReFa names directly, and the mechanism is simple: the same three-level bristles that detangle and polish also help distribute the oil evenly through the lengths instead of leaving it sitting where it was applied. One brush, one extra job, no separate tool required.
It is worth flagging that this is where the AILE BRUSH and the AILE BRUSH RAY part ways again. ReFa recommends the RAY on bare hair rather than after oil, since its natural pig bristles hold onto moisture and oil differently than the standard bristle mix. Same shape, same shelf, genuinely different advice, which is why checking the model rather than the family matters here too.
How do you clean the ReFa Aile Brush?
Clear loose hair and dust from the bristles as you would with any brush, that alone covers most days. If it needs more than that, a rinse under water is fine given what the waterproof answer above already covers: shake off what is left, wipe away any remaining droplets, and let it dry somewhere shaded and well ventilated rather than in direct sun.
Skip the hair dryer for this part. ReFa is specific that sitting the brush in hot air for any length of time can warp or damage it, so patience does more good here than speed. Bristles are not replaceable on this model either, so a brush that is starting to fray or feel worn after heavy use is a sign to replace the whole unit rather than a part.
Honest limitations: what it won't do
It will not treat a scalp. The rounded bristle tips are comfortable against the head, but there is no ion plate, no massage structure, nothing built specifically for scalp circulation the way the ION CARE BRUSH PREMIUM or the AURA are. Buy this for the lengths and let it be gentle on the scalp as a side effect, not the reason you bought it.
It will not replace a shower brush, and it should not try to. If your routine wants a tool in the shower distributing conditioner, that is the ION CARE BRUSH PREMIUM's job, not this one's. It also runs in fewer finishes than the HEART BRUSH, four against ten, so anyone shopping on colour first may find the decision made for them before the bristles come into it at all. None of that makes it a lesser brush. It makes it a specific one, built for a specific head of hair, and that specificity is the actual case for buying it.
The pairing our shoppers keep choosing: the AILE BRUSH alongside TAMBURINS Chamo. A hair tool and a fragrance from two different cities, the kind of pairing that turns up in the same order more often than either alone, and together they comfortably clear the free shipping threshold to Australia and New Zealand.

Frequently asked questions
Is the ReFa Aile Brush the same as the Heart Brush?
No. Both use the same three-level detangling and polishing bristles, but the AILE BRUSH has a wider, contoured head built for broader sections and thicker or longer hair, while the HEART BRUSH is a compact heart shape built for precision and comes in more colourways.
Is the ReFa Aile Brush waterproof?
Not fully, but it is not fragile either. It can get wet without being damaged, but it is designed for dry-hair detangling and polishing rather than shower use. For shampooing and conditioning, ReFa points to the ION CARE BRUSH PREMIUM instead.
Can you use the Aile Brush with hair oil?
Yes. Brushing through after applying hair oil helps distribute it evenly through the lengths and can make tangles easier to work through.
Which hair types suit the Aile Brush best?
Thick, long or slow-to-detangle hair, where the wider head clears more per stroke. Fine or short hair generally suits the compact HEART BRUSH better, and rough or tangle-prone texture is better matched to the AILE BRUSH RAY's natural bristles.
How many colours does the Aile Brush come in?
Four: Rose Gold, Silver, Matte Black and Pearl White.
Where can you buy the ReFa Aile Brush?
SoJan sources it in person from authorised retailers in Tokyo. Free delivery is available, and we ship to Australia and worldwide without customs surprises for local buyers.
