Smoothing treatment or hair botox: which should you choose?

Two salon appointments, two durations, one shared length guide.

By Manel, M BRUSH5 min read

The essentials

The deep hair botox treatment lasts around 2 to 2.5 hours; the smoothing treatment takes 4 to 6 hours depending on length. In both cases, the consultation and the blow-dry are included, with no extra charge for the blow-dry or the straighteners. Hair botox is a treatment distinct from the smoothing treatment, with its own page and its own booking.

"Smoothing treatment or hair botox?" The question comes up with every client discovering the smoothing bar and the hair care bar at M BRUSH. Both are salon appointments, long ones, that end with a blow-dry. But they are two distinct services, each with its own page and its own booking.

Here is what Manel sets out for each, with no promise of a result she does not deliver: the duration, the steps included, the length grid, the options. It is up to you to see what fits your day and your wishes.

What sets the two appointments apart

The two names point the way: a treatment on one side, a smoothing treatment on the other. In practice, here is what is written on the House page.

The deep hair botox treatment hydrates the lengths, without touching up the roots; depending on the product and the consultation, an optional smoothing effect with a flat-iron finish is possible, without giving the result of a smoothing treatment. In both cases, the blow-dry is included, with no extra charge for the blow-dry or the straighteners. You will find the up-to-date prices on the smoothing bar page and on the hair care bar page.

Two appointments, one same promise: leaving with your hair done.

Duration, the first criterion

It is the simplest difference to measure. The deep hair botox treatment takes around 2 to 2.5 hours. The smoothing treatment takes 4 hours on short and mid-length hair, and 5 to 6 hours for long and beyond.

If your afternoon is limited, the treatment fits more easily into a schedule. If you can free up half a day, the smoothing treatment becomes possible. In both cases, the slot is blocked in full at booking: no one goes before you, no one waits after.

Lengths, the second criterion

Both appointments share the same length guide, seen from behind: short to the nape, mid-length to the shoulders, long below the armpits, extra-long below the ribs, extra-long to the waist. Beyond the waist, it is by quotation.

The prices are not the same, and the smoothing treatment adds a supplement for dense or very dense hair. Look at the total on screen before confirming: it displays for the length you have chosen.

Unsure? Send Manel a photo of your hair from behind: she will confirm the right category before you come.

Choosing according to your situation

Rather than looking for the right answer in the abstract, start from your diary and your wishes:

  • You have around two and a half hours: hair botox fits into a late morning or an early afternoon.
  • You can free up half a day: the smoothing treatment is possible, with its 4 to 6 hours.
  • You want a shorter service: the blow-dry remains our signature blow-dry, from 30 to 60 minutes depending on length.
  • You are still unsure: write your question in the "note" box at booking. Manel replies before the appointment.

To gauge the difference with a blow-dry, see how long a blow-dry lasts.

The options, common to both

With either one, the tidy-up of the ends is complimentary, if you wish: only the ends are trimmed, the cut does not change. The care kit, a trio of shampoo, mask and serum, is offered at a gentler price when bought with a smoothing treatment or a hair botox, and it can also be bought on its own.

All textures are welcome, with no supplement linked to texture: only length changes the price.

On the day, in practice

Whichever appointment, the journey is the same. You book online, Manel confirms, and the directions arrive with the confirmation. The salon is at Avenue d'Yverdon 4, 1004 Lausanne. No deposit is required: everything is settled on site, in cash or by TWINT.

Something unexpected? The appointment can be cancelled or postponed by giving at least 24 hours' notice.
