Why is cutting hair on Wednesday forbidden? Unveiling the ancient belief all Thais should know.

Many Thais have heard elders warn, "Do not cut your hair on Wednesdays." People often notice that most barbershops close on Wednesdays, leading to curiosity about the origin of this belief and whether it still needs to be observed today. Thairath Online will provide the answers.

Unveiling the origin: Why did ancient people forbid haircuts on Wednesdays?

The belief in not cutting hair on Wednesdays is not mere superstition but has roots linked to historical and social contexts of the past. The main reasons can be divided into two points as follows.

1. The day of the monarch and senior nobility

Historical records state that in ancient times, Wednesday was typically when the king and royal family performed water-pouring ceremonies and haircuts (hair trimming). Skilled barbers, called "kalabok" (barbers), were summoned to serve in the royal palace. As a result, general barbershops outside the palace lacked skilled barbers, and common people adopted the custom of not cutting hair on Wednesdays to show respect and avoid equating themselves with royalty.

2. Agricultural strategy and astrological beliefs

According to ancient beliefs, Wednesday is the day of growth and fertility (often associated with Mercury in agriculture). Using sharp objects to cut anything on Wednesday was seen as disrupting growth or destroying auspiciousness. Therefore, people forbade cutting hair, trimming trees, or performing cutting-related auspicious activities on this day.

Besides the Wednesday taboo, the Brahma Chart text and ancient beliefs also specify "good days" for haircuts to bring good luck, as follows.

  • Monday is believed to enhance charm and attract love and kindness.
  • Thursday, the Teacher's Day, is believed to offer protection and bring wealth if hair is cut on this day.
  • Friday enhances attractiveness, popularity, and smooth success in endeavors.
  • Sunday boosts auspiciousness, longevity, and good health.

NoteThe belief in auspicious days is a matter of personal discretion.

Is the "no haircut on Wednesday" belief still necessary today?

Nowadays, social contexts and lifestyles have changed significantly. The prohibition against cutting hair on Wednesdays has gradually lost its strictness. Many barbershops now open on Wednesdays to meet consumer needs. However, some traditional barbershops may still observe the custom of closing on Wednesdays.

Ultimately, choosing which day to get a haircut depends on individual convenience and personal preference. If it causes no harm to oneself or others, any day can be considered a good day.
