“Cutting too short at once”: this hairdresser reveals the biggest mistake when switching to a bob

The bob haircut remains the star of salons in 2026. From the ultra-smooth old-money bob to the Italian-style blurred bob, this cut appeals as much to celebrities as to customers in a hurry to change their head before summer. However, there’s one mistake that comes up again and again for those who want to take the plunge too quickly.

Why the bob haircut is dominating hair trends

On social networks and red carpets alike, the bob is everywhere. Hailey Bieber, Emma Stone and Gracie Abrams have all adopted the bob in recent months. Naturally, this visibility is driving many women to try out the trend.

From a graphic chin-length bob to a long, shoulder-length bob, there’s no shortage of variations. So there’s a style to suit every body type. This versatility goes a long way to explaining the enduring success of the bob haircut.

Before making an appointment, it’s best to be aware of the trap many customers fall into. Hairdressers note a recurring mistake that often leads to regret.

The most common mistake according to a professional hairdresser

Pitfall number one? Cutting it way too short all at once. Keeks Reid, Cosmopolitan UK’s beauty director and a trained hairdresser, calls this “the biggest mistake” when you want to go from long hair to a bob.

“The problem isn’t necessarily the square itself, but the change that’s too radical.”

A very short haircut can be hard to live with when you’ve been used to lengths for years. As a result, many people think they don’t like their new head when they’ve simply cut it shorter than they imagined.

What’s more, a very short bob limits styling options. Styles, waves, blurred wavy effects: some possibilities quickly disappear with less length.

What to ask your hairdresser for a successful bob cut

The best thing to do is to go gradually. Keeks Reid advises you to ask for a slightly longer version than you initially imagined. You can always shorten it at the next appointment.

• A square with a little length
• Matter for texturizing
• A cut that’s easy to style every day
• A lob (long square to the collarbones) to test the trend
• A cut that preserves styling versatility

The ideal first bob? Start with a lob that reaches the collarbones or skims the shoulders. This length lets you test the style without losing all freedom of movement.

It’s better to cut step by step. You can always shorten more, but it takes months to go back. This gradual approach avoids unpleasant surprises.

Trendy variations of the square in 2026

Several styles dominate this season. The ultra-smooth old-money bob appeals to fans of sober elegance. On the other hand, the blurred Italian bob is ideal for those looking for more movement.

The graphic chin-length bob remains a daring option for the more daring. However, this length requires regular maintenance and leaves little room for hairstyle variation.

For thicker hair, certain textured versions provide lightness and controlled volume. The hairdresser can adapt the cutting technique to the nature of the hair.

How to avoid regrets after your bob haircut

Communication with your hairdresser plays a key role. Bringing in reference photos helps clarify expectations. It also helps to check that the desired length corresponds to reality.

Before taking the plunge, it’s a good idea to simulate a bob cut with pins in front of a mirror. This gives you a first idea of the result and helps you adjust your expectations.

Patience is your best ally. A square can always be shortened on a future visit. On the other hand, it takes several months to regain lengths lost too quickly.

Hairdressers generally recommend a follow-up appointment four to six weeks after the first cut. This allows time to refine the shape and adjust the length if necessary.
