Collarbone Length Haircuts and Sleek Armpit-Length Cuts

A sleek cut that ends at the collarbone or just below, around armpit length, is one of the easiest lengths to wear. It frames the face, stays off the shoulders and still lets you tie your hair back. Bring a photo to your stylist and say where you want the ends to land: on the collarbone, or a hand's width lower.

Below are the versions worth saving, who each one suits, and how to keep the finish smooth without a daily fight with a flat iron.

Section 01

What counts as a collarbone-length cut?

The ends sit at or just under the collarbone, and the hair touches your shoulders when you turn your head. Armpit length is a few inches lower, so the ends fall onto the chest and move more when you walk. Sleek simply means the surface is smooth and the ends are cut cleanly, whether that comes from blunt cutting, a blowout or naturally straight hair.

The two lengths read differently. Collarbone length looks sharper and more tailored. Armpit length looks softer and a bit more relaxed, and it gives you room to wear a low ponytail.

Who does collarbone length suit?

Most people can wear it, which is why collarbone length haircuts for women are so common. The length adds almost no weight at the jaw, so it works with round, square, oval and long face shapes. What changes is where the cut puts its emphasis.

• Round or soft faces: keep the front pieces a little longer than the back so the lines run downward.
• Strong jaws: a slight bend at the ends softens the outline.
• Long faces: a blunt, full line at the collarbone adds width where the face needs it.
• Fine hair: stay blunt. A one-length cut looks thicker than a heavily thinned one.

Through the lens of evidence-based design, I'd look at the outline first. The eye reads the shape of a haircut before it reads color or texture, so the line where the hair ends does most of the work.

Sleek and straight styles

For collarbone length haircuts straight hair is the easiest starting point. A blunt cut with a very slight bevel on the underside makes the ends turn in a little without any styling. A center part looks formal and symmetrical. A deep side part is softer and adds some lift at the root.

If you smooth with heat, the American Academy of Dermatology advises that flat irons should be used on dry hair on a low or medium heat setting, no more often than every other day. A good blowout and a smoothing brush can do the rest on the days in between.

Layers and face-framing pieces

Collarbone length hair with layers works best when the layers are long and kept mostly in the front. Short layers on a cut this length can make the ends look thin. Ask for pieces that start around the chin and blend into the length, so the sleek look stays and your face gets some movement.

If you want the same idea at a longer length, the armpit-length layered haircut shows how the layers change as the hair gets longer.

Section 05

Bangs: curtain, wispy or none

Collarbone length haircuts with curtain bangs are a good in-between choice. The bangs part in the center and sweep to the sides, so they grow out without an awkward stage. They also keep a sleek cut from looking too severe.

A blunt fringe is a bigger commitment and needs a trim often. If you want a lighter option, the shoulder-length wispy haircut has the same airy feel.

Section 06

Waves, curls and low-maintenance options

Naturally wavy or curly hair can wear this length too, but it looks different. Curl pulls the hair up, so a cut that starts at the collarbone when wet can sit closer to the shoulders when dry. Ask for the cut to be shaped on dry hair, and see the armpit-length wavy haircut and the armpit-length curly haircut for more texture ideas.

Low maintenance collarbone length haircuts share a few traits: one main length, a few soft face pieces, and a shape that looks fine air-dried. Skip anything that depends on perfect daily styling.

Section 07

How to keep a sleek finish

Smooth hair is mostly about the surface staying intact. Detangle gently, because the AAD notes that hair is delicate when it's wet, so a wide-tooth comb is better than a brush for detangling wet hair.

A leave-in conditioner can help too. Board-certified dermatologist Zoe D. Draelos, MD, FAAD, says of using one: "You should see less frizz. Your hair should be easier to brush or comb, so you'll have less breakage."

As an architect trained in evidence-based design, I'd also pay attention to shine. A smooth surface reflects light in one direction, which is why sleek hair looks darker and more saturated than the same color with frizz. If you want a quick comparison at a similar length, the shoulder-length sleek haircut is the shorter version, and the bra-strap length haircut is the next step down.

Plan a trim every couple of months to keep the ends crisp. With a blunt line, split ends show up quickly.
