Long and extra-long hair: timing, hold and finishes
More length, more patience, and a shine that runs all the way to the ends.

Choose your finish
The essentials
On mid-length, long and extra-long hair, a blow-dry takes longer because there are more sections to dry and work through. Sleek is the finish that shows off length best: the weight of the hair helps it hold. The ends, which are more fragile, deserve particular attention.
A long, well-brushed head of hair is one of the loveliest things a blow-dry can produce. It is also the one that asks for the most patience: more length, more sections, more care at the ends.
Here is what to know before you book, so you can choose your finish well and make the result last.
Mid-length and long, or extra-long: where you stand
Length is decided before we begin, using three markers: the nape, the shoulders and the bottom of the ribs.
- Mid-length and long: your hair falls from the shoulders to just above the bottom of the ribs.
- Extra-long: it starts at the bottom of the ribs and goes beyond, towards the middle of the back or lower.
Stand with your back to a mirror, a second mirror in hand, or ask someone to look: it is the longest tip that counts, not the average.
If you are torn between two categories, our article on choosing your hair length will help you decide.
Why it takes longer
The appointment follows the same four stages as on short hair: detangling, sectioning, finishing, setting. But each of these stages grows with length.
Detangling.On long lengths, it is done from the ends up towards the roots, little by little, so as not to break the fibre. One forgotten knot ends up under the round brush.
The sections.There are more strands to separate. A section that is too thick does not dry to the core, and a strand still damp inside swells within the first hour.
Drying the ends.The brush makes a long journey from root to tip. Each strand needs several passes, then a proper cool-down.
For these reasons, plan your appointment without rushing off afterwards. Curled finishes, with the brush or the iron, take a little longer still than the others.
Sleek, the finish for lengths
On mid-length, long and extra-long hair, the sleek blow-dry has an ally: weight. The lengths naturally pull the strand downwards, and sleek holds well.
Above all, it is the finish that shows the length itself: a regular surface over which the shine runs from crown to ends.
For those who want an even sharper result, the straightener option can be ticked when booking. It makes full sense on long lengths, where the slightest deviation shows over such a long journey.
This glossy sleek look also matches a well-identified trend: according to Marie Claire UK, "glass hair" is among the trends that marked the autumn-winter 2026-2027 shows.
We explain how to achieve it in our article on glass hair, the mirror sleek. Very long lengths themselves were noticed on this season's catwalks, at Chloé and Acne Studios.
The other finishes on long lengths
| Finish | On long lengths | Good to know |
|---|---|---|
| Soft | Movement at the ends | Avoids the "curtain" effect |
| Volume | Root pulled downwards | Shows mostly at the ends |
| Brush curls | Curls that open out | Stretch under their own weight |
| Iron curls | More defined curls | Resist stretching better |
Soft keeps the hold of the blow-dry and simply rounds the ends. With volume, weight works against you, especially on fine hair: it stays more discreet than on a bob.
Long lengths, on the other hand, offer all the room curls need, opening out as they fall, under their own weight.
On long hair, every extra centimetre shows, in beauty as in flaw.
The ends, the most fragile part
The tip of a long hair may be several years old. It has known brushings, sun, friction, and it is often drier than the root.
A sleek finish puts those ends in full light: a split or dried-out end shows more on a perfectly straight surface.
Cutting is not on the M BRUSH menu. If your ends need refreshing, plan it a few days before your blow-dry, or ask for the end refresh, offered with a smoothing treatment or a hair botox treatment. And day to day:
- protect them from heat when you style them yourself, with a heat protector;
- avoid tying them in the same place every time with a tight elastic;
- beware of friction: bag straps, the collar of a wool coat, the back of a chair.
Making a long blow-dry last
Long lengths have their own enemies, and it is worth knowing them.
- Friction against the back. A backpack, a thick scarf or a coat collar crease the lengths and create static. Carry your bag on your shoulder and keep your hair out of the collar.
- At night. On a long sleek, the "wrap" keeps the lengths straight: hair wound around the head, held with flat clips. Otherwise, a very loose braid or a soft bun on a silk pillowcase. The detail is in our article on making your blow-dry last overnight.
- Humidity. Lengths absorb moisture from the air and start to wave: an umbrella and a roomy hood are your best protection.
Booking a blow-dry on long hair
On the booking page, choose mid-length and long, or extra-long, then your finish, and the iron option if you want an even sharper sleek. All that is left is to pick a free slot.
No online payment and no deposit: everything is settled on the day.
Come with clean hair, without oil, serum or styling product, even on ends that usually ask for it. Shampoo + care optional on site; otherwise, the whole appointment is devoted to the blow-dry. The only effort of the day: sitting down.

Frequently asked questions
- How long does a blow-dry take on very long hair?
- Longer than on short hair, because there are more sections to dry and work through. Curled finishes take a little longer still than sleek or soft.
- Does a blow-dry hold better on long hair?
- Sleek does, because the weight of the lengths helps it stay straight. Volume at the root, on the other hand, holds less well, precisely because of that weight.
- How can I stop long hair from tangling after a blow-dry?
- Avoid friction against the back, sleep on a silk or satin pillowcase, and detangle with your fingertips rather than with a tight brush. ---
