Afro-Caribbean natural hair care can be tricky, because the shops don’t tend to sell many specialty products, and even less so organic vegan ones. Many people simply use shea butter (avoid for latex allergies) or coconut oil on dry frizzy hair (the latter is sometimes used for dreadlocks). Be careful in cold climates, as coconut oil solidifies at low temperatures, so could make hair stiff (best to use on your scalp, as the heat from your head will prevent this).
The book Kink Alchemy (by the Caribbean cookbook author above) has recipes for Moringa Hair Butter, Coconut Styling Conditioning Milk and Lemon Twist Mist, Black Soap Hair Wash and Papaya Reverse the Breakage Mask.
Dreadlocks are where the hair coils naturally matt. Some people (like Rastafarians) do this for religious reasons, others do it simply because they like the look. The hairstyle was made popular in the music world when Bob Marley had them.
If you have dreadlocks, wash your hair every few days, after ‘giving your head a good shake’ to dislodge fibres. Avoid conditioner as it can cause dreadlocks to untwist. London Dreadlocks uses organic products to build, detangle or remove dreadlocks.
