How to Use a Straightening Serum + 8 Serums to Try

How to get smooth and silky hair with a straightening serum.

Whenever it’s time for me to straighten my naturally curly hair, I always opt for a straightening serum. For me, it’s more about using a product that doesn’t revert my hair back to its naturally curly state after blow-drying. Plus, the shine factor that a serum provides without the weighed down feeling can’t be matched.

Over the years I’ve experimented with many straightening serums. I’ve even gone as far as trying natural oils that have a serum-like consistency like Argan oil. However, a true straightening serum is different than oil, as it acts as a barrier from heat—similar to a heat protectant—to ensure that your hair stays protected, smooth, and super shiny.

A little goes a very long way with this stuff. Another thing to love is that serums can also prevent frizz. There’s nothing like straightening your hair and having it last for only an hour. When applying the serum, focus more on the areas you tend to see the most frizz. Keep scrolling to learn how to use a straightening serum and find out some of our favorites.

There are many ways to use a straightening serum on your hair. However, one rule we suggest you don’t break is: Don’t apply too much. A few drops really goes a long way. You can also opt for applying it to your hair as you style. To do this, section off your hair, apply your serum, then blow-dry or flat-iron and continue this process with the rest of your hair.

Serums can also be applied after styling your hair for additional shine. If you’re using it as an aid for straightening your hair, it’s best to apply before heat styling.
