Seeing flakes? Massage some almond, peppermint or tea tree oil onto your scalp before shampooing (or add a few drops straight into your shampoo) to soothe itchiness, nix dryness and increase circulation to your hair follicles. Also, if you suffer from any other scalp conditions (i.e. dermatitis, psoriasis), consider using kalahari melon seed oil to soothe the irritation.

Though it’s true that thin hair is prone to getting greasy, this doesn't mean you should eliminate oils all together. Fruit oils like avocado or Abyssinian (aka organic crambe seed oil) have a lightweight texture that absorbs quickly so you get conditioning benefits without weighing things down. Also avoid applying it directly to the roots. Mix it into your pre-heat styling product or use it as deep conditioning treatment to protect hair against damage and boost shine.

Fact: More moisture equals more defined curls. Massage a few drops of a heavier oil like coconut, kukui nut or black castor oil into damp hair (or mix some in with your styling cream) to reduce frizz and add shine as it dries. When it comes to coconut oil specifically, less is more, so try to focusing on the ends rather than the scalp.

If you haven’t quite made the transition back to your natural hair, let oils help make the process a little bit easier (even if you’re not up for the big chop). Relaxing hair can chemically alter its texture (aka make it straighter) and lead to breakage, thinning and preventing any new hair growth. So, consider using argan, castor or jojoba oil to repair and replenish dry ends, reduce frizz and encourage healthy hair over time.

When you have chemically treated or processed hair, chances are your strands can get very dry. Look for something with baobab, argan or marula oil. Both have high levels of antioxidants, which will improve elasticity in your hair (key to preventing breakage) and protect against UV rays (key to preserving your color).

If you’re lacking moisture, chances are heavier oils like argan, moroccan (which is just even a more purer form of argan), macadamia or jojoba can bring your hair back to life. Both are rich in fatty acids and vitamin E and can be used as a pre-shampoo treatment to tame any frizz, soften your strands or put on split ends to seal them in. Just a dime-sized amount (or a nickel-sized if your hair is really dry) can do the trick.

Yup, you read that correctly. Just because you have oily hair doesn’t mean you can’t get the benefits of hair oils. Tea tree, rosemary, lemon and lavender oil can help remove excess buildup and improve the scalp. It's important to note you want to use a small amount to avoid the oils weighing down your hair and leaving your scalp greasy.
