Hair serum or hair oil—which one should you reach for? While both play a vital role in hair care, they serve different purposes. Hair serum is your go-to for instant shine, frizz control, and heat protection, while hair oil dives deep to nourish, strengthen, and hydrate your scalp and strands.
The best choice? It all depends on your hair type, concerns, and styling routine! Let’s break it down so you can pick the perfect match for your locks.

Using Heavy Oils on Fine Hair:
Choose lighter oils like argan or jojoba if you have fine or thin hair.
