Shea Moisture Jamaican Black Castor Oil Strengthen & Restore Treatment Masque (£11) is worth every bit of its five-star review that you'll find on most websites. The reason it's a bestseller is because of the incredible cocktail of ingredients. "Anything with Jamaican black castor oil works incredibly with type 4 Afro hair, in addition to shea butter, which is lauded for its thick, superhydrating consistency," says Kia. It also contains peppermint which not only feels invigorating on your scalp, but also has antibacterial and antimicrobial properties that relieve dry scalp." Apple cider vinegar is also great for calming irritation and relieving dandruff. "This mask works wonders on bleached Afro hair, and make sure to try it as an overnight treatment, because it will get you hooked," she adds.
