Solid conditioner bar: how to use it, and do you really need one?

Applying the HORIZON conditioner bar to wet lengths
✦ The short answer

A solid conditioner bar goes on after shampoo, on hair that has been squeezed out but is still damp: rub it along the lengths and ends, never the roots, leave it for one to two minutes, then rinse. It replaces bottled conditioner. It is most useful if your hair tangles, or is long, dry or curly.

How do you use a solid conditioner bar?

Many customers write to me after their first try: “I'm not sure how much to use.” That's normal, there's no visual cue, no dollop of cream in your palm. Here is the routine, in four steps.

  • Gently squeeze out your hair after shampooing. It should stay damp, not dripping.
  • Rub the bar straight onto the lengths and ends, avoiding the roots. Three or four strokes per section are enough.
  • Leave it on for one to two minutes, while you wash.
  • Rinse in lukewarm water, until your hair slides through your fingers without catching.
A customer's tip that I now pass on to everyone: hold the bar under hot water for a few seconds before applying it. The surface softens into a kind of milk that spreads much more easily.

On wet or dry hair?

On wet hair, always, for everyday use. The detangling agents need water to glide along the hair shaft.

For very dry hair, two variations work well. You can leave a little in by not rinsing the ends completely. Or use it as a mask: apply it to the lengths, leave it for five to ten minutes, then rinse.

Why are my lengths greasy after conditioning?

When it happens, it is almost always about the amount or where you applied it, rarely about the formula:

What you noticeLikely causeWhat to do
Flat roots, hair gets greasy fasterApplied too close to the scalpStart at ear level
Heavy, slightly tacky lengthsToo many strokesTwo strokes per section, no more
Oily film after dryingRinse too shortRinse longer, in lukewarm water
Fine hair weighed downApplied along the whole lengthEnds only

And if it happens anyway, nothing is lost: a shampoo the next day resets everything, and you adjust the amount next time.

Do I really need a conditioner?

Not necessarily, and I'd rather tell you so. If your hair is short, fine and detangles on its own after washing, a good shampoo is enough.

It becomes useful as soon as hair tangles: long, curly, dry or coloured hair, or hair worn out by summer sun. In those cases, skipping conditioner mostly means breaking more hair when you comb it.

Bar or bottle: what's the difference?

The most concrete difference is in the ingredient list. In a typical liquid conditioner, water usually comes first. In HORIZON, water only comes eighth: what you rub onto your hair is the active ingredients.

You notice the lack of silicones most after a few weeks. Silicones coat the hair and feel soft instantly, but they build up wash after wash. Without them, the softness comes from linseed and sweet almond oils, and nothing piles up on the hair.

Which shampoo should you pair it with?

HORIZON works after any shampoo, solid or liquid. With our shampoo bars, the pairs I recommend most are NEPTUNE and HORIZON for most hair types, ZEFIR and HORIZON for curls.

If you're just starting out, read how to use a shampoo bar first: the shampoo sets things up. And if you want the whole routine in one go, the Perfect Hair kit brings together a shampoo bar of your choice, HORIZON and a beech wood comb.

How do you store it?

Like a shampoo bar: dry, between uses. Set it on something that lets water drain, out of the shower stream. A bar left sitting in water softens and wears down twice as fast.

Frequently asked questions

What I'm asked most often about conditioner bars.

Do you rinse out a conditioner bar?
Yes, for everyday use: one to two minutes, then rinse in lukewarm water. On very dry hair you can leave the ends slightly unrinsed.
Can you use it as a hair mask?
Yes. Apply it to the lengths, leave it for five to ten minutes, then rinse. It helps at the end of summer, on dry ends.
Is it suitable for fine hair?
Yes, as long as you apply it to the ends and mid-lengths only. On the roots, it weighs down any fine hair.
How long does a conditioner bar last?
HORIZON lasts up to 60 uses, the equivalent of four 250 ml bottles. It depends on the length of your hair and on letting it dry between uses.
Does it contain silicones?
No. HORIZON detangles with rapeseed-derived agents and nourishes with plant oils. It contains no silicones and no essential oils.
