Appearance

Rastas use their physical appearance as a means of visually demarcating themselves from non-Rastas. Male practitioners will often grow long beards, and many Rastas prefer to wear African styles of clothing, such as dashikis, rather than styles that originated in Western countries. However, it is the formation of hair into dreadlocks that is one of the most recognisable Rasta symbols. Rastas believe that dreadlocks are promoted in the Bible, specifically in the Book of Numbers, and regard them as a symbol of strength linked to the hair of the Biblical figure of Samson. They argue that their dreadlocks mark a covenant that they have made with Jah, and reflect their commitment to the idea of 'naturalness'. They also perceive the wearing of dreads as a symbolic rejection of Babylon and a refusal to conform to its norms regarding grooming aesthetics. Rastas are often critical of black people who straighten their hair, believing that it is an attempt to imitate white European hair and thus reflects alienation from a person's African identity. Sometimes this dreadlocked hair is then shaped and styled, often inspired by a lion's mane symbolising Haile Selassie, who is regarded as "the Conquering Lion of Judah".

Rastas differ on whether they regard dreadlocks as compulsory for practicing the religion. Some Rastas do not wear their hair in dreadlocks; within the religion they are often termed "cleanface" Rastas, with those wearing dreadlocked hair often called "locksmen". Some Rastas have also joined the Ethiopian Orthodox Tewahedo Church, the Christian organisation to which Haile Selassie belonged, and these individuals are forbidden from putting their hair in dreadlocks by the Church. In reference to Rasta hairstyles, Rastas often refer to non-Rastas as "baldheads", or "combsome", while those who are new to Rastafari and who have only just started to grow their hair into dreads are termed "nubbies". Members of the Bobo Ashanti sect of Rastas conceal their dreadlocks within turbans, while some Rastas tuck their dreads under a rastacap or tam headdress, usually coloured green, red, black, and yellow. Dreadlocks and Rastafari-inspired clothing have also been worn for aesthetic reasons by non-Rastas. For instance, many reggae musicians who do not adhere to the Rastafari religion wear their hair in dreads.

From the beginning of the Rastafari movement in the 1930s, adherents typically grew beards and tall hair, perhaps in imitation of Haile Selassie. The wearing of hair as dreadlocks then emerged as a Rasta practice in the 1940s; there were debates within the movement as to whether dreadlocks should be worn or not, with proponents of the style becoming dominant. There are various claims as to how this practice was adopted. One claim is that it was adopted in imitation of certain African nations, such as the Maasai, Somalis, or Oromo, or that it was inspired by the hairstyles worn by some of those involved in the anti-colonialist Mau Mau Uprising in Kenya. An alternative explanation is that it was inspired by the hairstyles of the Hindu sadhus.

The wearing of dreadlocks has contributed to negative views of Rastafari among non-Rastas, many of whom regard it as wild and unattractive. Dreadlocks remain socially stigmatised in many societies; in Ghana for example, they are often associated with the homeless and mentally ill, with such associations of marginality extending onto Ghanaian Rastas. In Jamaica during the mid-20th century, teachers and police officers used to forcibly cut off the dreads of Rastas. In various countries, Rastas have since won legal battles ensuring their right to wear dreadlocks: in 2020, for instance, the High Court of Malawi ruled that all public schools must allow their students to wear dreadlocks. The decision to begin to be enforced before the 30th of June 2023 of schools will be in breach of the country's constitution.
