Sebastian Potion 9: The Cult Leave-In, Explained

Potion 9 has been in salons for decades and still sells out. It's a leave-in that does two jobs at once, it conditions and gives a light, workable hold, which is why people get hooked on it.

What it actually does

It's built around nine botanical ingredients that smooth and soften, while a light styling base lets you shape hair without it going crunchy. Think of it as a treatment you can also style with.

How to use it

Work a small amount through towel-dried hair, mid-lengths to ends, then style as normal. A little goes a long way, so start small and build up. It's just as happy on dry hair as a midweek refresh.

The range

Alongside the original there's a Lite version for finer hair, a leave-in conditioner and styling cream, and the Pro Grade Powder for instant texture and lift at the roots. See the Potion 9 range →

Who it suits

If your hair drinks up product and still wants movement, Potion 9 is a safe bet. Drier and coarser hair loves the original; finer hair will get on better with the Lite.
