How to buy the right hair serum for you

What are hair serums used for?

We all know hair serums can help define your style, smooth frizz, and add shine and texture to your hair. But they are much more than that. With formulas that protect against heat, sun exposure, and pollutants, they’re essential for achieving salon-quality hair without leaving the comfort of your home.

What is the difference between a hair oil and a hair serum?

It’s simple: hair oils penetrate deep into your hair follicles for ultimate conditioning and nourishment. If you suffer from very dry hair, a hair oil is your best bet. Hair serums, on the other hand, coat the outside of your locks like a protective styling tool.

You can apply hair oil to wet or dry hair, and as a moisturizing mask. But you only need a few drops of hair serum, applied to wet hair, for the magic to work.

What hair serum do I need?

Consider your hair type, texture, and concerns and choose a hair serum accordingly. Finer textures will benefit from a lightweight, volumizing formula, while curlier hair types should opt for a hair serum that will smooth strands and fight humidity.
