AI Long Hair Filter: Add Long Hair, Keep Your Face

See yourself with long hair before two years in the awkward middle — the finish line on your own photo, and proof the wait is worth it.

Before / after

Same person, two lengths

A real length change, produced on this page’s model. Drag the divider: the same woman, the same cream top, the same grey studio backdrop and the same expression — the pixie cut has become dark waves well below the shoulders, with the parting and the shadows on the shoulders rendered to match. Your own photo gets the same length, parting and shoulder shadows built around you.

Long hair filter: three lengths on the same face

One short pixie cut, grown out three ways: straight to the waist, loose waves, curtain bangs. Same smile, same top, same wall. Tap a length and drop in your own photo.

Straight to the waist

Straight to the waist

Give this person long hair: the same hair colour grown out straight and sleek to waist length, falling behind the shoulders with a soft middle part and realistic strands. Keep the same face, clothing, background, lighting and framing. Keep the exact same person — same face, identity, skin tone and expression — photorealistic, no text, no watermark.

Long beach waves

Long beach waves

Give this person long hair: the same hair colour grown into long loose beach waves past the chest, with natural volume and a few face-framing pieces. Keep the same face, clothing, background, lighting and framing. Keep the exact same person — same face, identity, skin tone and expression — photorealistic, no text, no watermark.

Long with curtain bangs

Long with curtain bangs

Give this person long hair: the same hair colour grown long below the shoulders with soft curtain bangs and a glossy blow-out finish. Keep the same face, clothing, background, lighting and framing. Keep the exact same person — same face, identity, skin tone and expression — photorealistic, no text, no watermark.

What is a long hair filter?

A long hair filter is an AI photo tool that shows you, on one photo of yourself, what you would look like with long hair, a question that is otherwise expensive to answer. Growing it out takes one to three years depending on where you are starting from, and the awkward middle is the part people quit during — so seeing the destination first is worth a lot.

Image tool

Upload a photo and the same person comes back with hair grown well past the shoulders, with realistic volume, a natural parting, individual strands and soft shadows where the hair rests. What must not move is everything else. The face, the skin tone, the expression, the clothes, the pose, the lighting and the background all carry over, because a preview is only useful if the length is the only thing that changed — if the face shifts too, you are looking at a stranger with nice hair and it tells you nothing about whether to grow yours out.

Your own hair, not a model

Your own hair, not a model

The length is grown on your own face rather than shown to you on somebody else. That sounds obvious and it is the thing most hairstyle apps quietly do not do, which is why their previews never quite answer the question you had.

Volume, parting and strands

Volume, parting and strands

Real volume, a parting that makes sense for your hairline, and strand detail — not a wig shape pasted over the head. Look at where the hair meets the shoulder: a pasted shape floats, grown hair casts a shadow and follows the fabric.

Want the extremes too? The bald filter goes the other way on the same photo, and the hair growth clip turns the transformation into video.

How to use

See the length in three steps

From one photo to a believable preview, with the cost shown before you commit.

  1. Take a straight-on photo

    Face the camera in even light with your whole head and shoulders in frame. Hair pushed back off the face gives the model a clean hairline to build from.

    Take a straight-on photo
  2. Say how long and what texture

    Mid-back, past the shoulders, collarbone length — and add the texture, because straight, wavy and curly at the same length look like three different people.

  3. Check credits and generate

    Generate, then set the new length beside the photo you started from — the moment you finally see the look you have been growing toward.

Who it's for

When you want to see it first

Getting through the grow-out, planning extensions, or settling the argument about which length suits you best.

Before you commit to growing it

Before you commit to growing it

Growing hair out takes one to three years, and most people quit in the awkward middle. Seeing the destination makes the middle easier to sit through.

Deciding with your stylist

Bring a picture of the length on your own face instead of a photo of someone else, so you are both discussing the same outcome.

Answers

Hair length FAQ

Common questions about previewing extra length on your own photo with Kavel.

It does, and that is the honest answer to what people are really asking. The face itself is meant to carry over unchanged and on a clear straight-on photo it does — but a length past the shoulders covers the jawline and narrows the visible outline of the head, so the same face can look longer or softer than you are used to. If the preview feels subtly off, that framing effect is almost always the reason rather than the model having altered your features, and it is genuinely what the length would do to you.

Yes. Even from a buzz cut, the model builds from your hairline and hair colour, so you get a clear test of the overall shape and colour on your own face before a single month of growing.

Yes, and you should. Say collarbone, past the shoulders or mid-back rather than just longer, and name the texture — straight, wavy, curly, coily — because the same length reads completely differently across textures. Adding your natural texture rather than the one you wish you had gives the more honest preview.

No. Those overlay a fixed hair shape onto your head, which is why they slip when you turn and why the hair never quite sits on your shoulders. Here the hair is rendered into the photograph with its own volume, parting and shadows, so it belongs to the picture rather than floating over it.

You can, but do it as a second run. Changing two variables at once makes the preview hard to judge — you will not know whether it is the length or the colour you are reacting to. Get the length right first, then change the colour on top of it.

Scalp hair grows roughly half an inch a month for most people, so going from a short cut to past the shoulders is commonly a two to three year project, and collarbone length around one to two. That range is exactly why previewing is worth a minute: the decision you are making is a multi-year one.

The estimate moves with the format and resolution you pick, so the cost is visible first. Failed runs are refunded automatically, and new accounts start with free credits — enough to compare two lengths before spending anything.

With their agreement, yes. Your own face is always fine, whatever the style — and it is where the preview answers the question you actually have.
