Guru Nanak, the founder of the Sikh faith, started the practice of keeping hair unshorn. Guru Gobind Singh, the tenth Sikh Guru, gave the Sikh nation articles of faith (including uncut hair), which as a whole comprise the daily uniform of a Sikh. Many Sikh scholars and theologians have interpreted meanings for each of the articles of faith; as many Sikhs have also reflected on the teachings of the Gurus and inferred their own reasons.
