Discover Paul Mitchell’s Super Skinny Serum
Paul Mitchell Super Skinny Serum is a lightweight smoothing serum designed to help cut down blow-dry time and calm frizz. Getting the most out of it comes down to how much you use and where you apply it, a formula this concentrated can work against you if it's applied the wrong way.
How much to use

One pump is generally enough for most hair types. Because the formula is concentrated, using more than you need can leave hair looking weighed down rather than sleek, it's worth starting with less and adding more only if you need it, particularly on finer hair.
Step-by-step application
● 1. Apply to damp, towel-dried hair. Rub one pump between your palms to warm the serum through before it touches your hair, this helps it distribute more evenly.
● 2. Focus on mid-lengths and ends first, where hair is driest and most prone to frizz, then smooth any remaining product upwards towards the roots.
● 3. Blow-dry as normal. The serum is designed to help support a faster, smoother dry, so you may notice less time at the mirror than usual.
● 4. Optional finishing step: once hair is dry, a very small amount smoothed over the surface can help tame flyaways and add shine, a little goes a long way here too.
Application tips by hair type
Fine hair: keep application strictly to mid-lengths and ends, and consider using slightly less than one full pump, fine hair shows weight and product build-up more quickly than thicker textures.
Curly hair: applying to soaking-wet rather than towel-dried hair can help the serum distribute more evenly through the curl pattern before styling.
Common mistakes to avoid
Applying too close to the roots is the most common issue, it's one of the fastest ways to end up with hair that looks greasy rather than smooth. It's also worth applying to damp rather than soaking-wet hair (unless you have curly hair, per above), since too much water can dilute how evenly the serum spreads. Finally, skipping the palm-warming step can leave the product sitting unevenly on the surface of the hair rather than working through it.
Pairing it with the rest of your routine

Super Skinny Serum is one part of a wider smoothing routine, for hair that's especially prone to frizz, it can help to pair it with a smoothing shampoo and conditioner rather than relying on the serum alone.
You can explore the rest of the Smooth range to find a shampoo and conditioner suited to your hair type.
