Undercut vs Fade: Disconnected or Blended Sides?

Disconnected vs blended: what that means in practice

'Disconnected' means the top and sides are not joined by a blend. On an undercut, we buzz the sides with one guard, often a 1, 2 or 3, up to a set height, and the long top starts immediately above it. When you let the top hang, it covers the short part like a curtain.

'Blended' means every length leads into the next. On a fade, the bottom might be skin, then a 1, then a 2, and so on, until the sides meet the top without a shelf. Our page on how barbers blend a fade explains that gradient.

You can combine them: a fade on the sides with a disconnected top is sometimes called a disconnected fade. That is still a fade on the sides; the undercut part is the sharp break at the top.

The practical differences side by side

Here is what changes day to day between the two.

How each one grows out

An undercut grows out more slowly in appearance, because one length gets longer evenly. The line between sides and top stays visible for weeks, and with a long top hanging over it most people cannot see the sides at all.

The catch comes if you want to stop wearing it. Because the sides are much shorter than the top, growing an undercut out means a few months where the sides stick out under longer hair. We usually tidy it with a scissor-over-comb shape until they catch up.

A fade shows growth earlier but grows out into something ordinary: after about a month it looks like a neat short cut, and you can keep going without an awkward stage. The full timeline is in how to grow out a fade.

Tops that suit an undercut and tops that suit a fade

An undercut needs a top with enough length to do something with, while a fade supports tops of any length.

• Man bun or top knot: undercut. The buzzed sides make tying hair back cooler and neater; see the man bun.
• Long slick back: undercut for the classic hard-part, high-contrast look, or a low fade for something softer.
• Crop, Caesar or short textured top: fade. An undercut under a short top just looks like a botched fade.
• Curly or coily top: usually a fade, which frames the curls without a shelf.
• Two-block style: this is a type of undercut; the two-block haircut page covers it.

When to choose the undercut, and when the fade

Choose an undercut if your top is 10 cm or longer, you like to tie or slick it back, you want the sides to disappear when your hair is down, or you prefer fewer visits, around every four to six weeks for the sides.

Choose a fade if your top is short or medium, you want a sharp, finished look in every direction, your workplace prefers blended cuts, or you might change styles in a few months and want an easy exit.

A hint from the chair: if the photo you brought shows a visible line between the sides and the top, you want an undercut, even if the person in the picture called it a fade.

How to ask for either one

For an undercut: 'Undercut, sides and back all with a 2 up to just below the parting line, disconnected, and keep all the length on top.' For a fade: 'Mid fade to skin on the sides and back, blended into the top, take a little off the length.' Naming the guard and the height stops any guessing.

We book either as Haircut Only, and the long top on an undercut is shaped with scissors. See our skin fades service for fades, or the full undercut style page.
