This one’s the most popular for a reason. Coconut oil isn’t some new-age beauty secret, it’s been used for generations. The fat molecules in coconut oil are small enough to penetrate deep into the hair shaft and strengthen it from within. Plus, it’s full of lauric acid, which helps prevent protein loss from hair, meaning less breakage and split ends.

How to use it:
Warm it up slightly so it’s easier to apply.

Massage it into the scalp using your fingertips in small circular motions. This boosts blood flow and helps the roots absorb the oil.

Work the oil through the length of the hair.

Leave it on for a few hours or overnight if you can, and then wash it out with a gentle shampoo.

People usually say it’s best when you apply it once or twice a week. It’s especially good if your hair is dry, frizzy, or chemically treated. It locks in moisture, so it’s also great if you live in places with harsh weather or hard water.
