Argan oil is one of the OG hair and skincare oils that is still popular for good reason: It’s a pure and natural oil that “helps smooth hair, reduce frizz and add shine,” says Olivia. “It contains fatty acids and vitamin E that adds moisture to hair.” In addition to being a great bang for your buck, this one can also be used on your face and body for instant nourishment. If you have fine hair, it may not be for you; a few reviewers noted that it was too heavy for limp strands.

Boasting an impressive list of almost 100% natural plant oils and extracts including castor, jojoba and rosemary, this hair thickening oil promotes longer locks. While reviewers generally raved about its efficacy and formula, a few noted that it left hair a little greasy after applying. “I typically keep my hair silk pressed and I’ve noticed since using this oil my hair holds the press much longer and humidity isn’t as much of a hassle as it was before I used this oil,” one reviewer notes. “I also noticed that I have much denser new growth than I did before, so I believe it is aiding in my hair growing faster and thicker.”
