Importance of Hair Visibility in Passport Photos

Head hair refers to the strands that grow on the scalp of humans. The average person has between 90,000 and 150,000 head hairs, a number that is determined by their genetics.

Facts about Hair

There are many interesting facts about hair that you may not know:.

• Hair grows at a rate of about 1 centimeter per month, or 0.3 millimeters per day.
• People typically have between 100,000 and 250,000 head hairs.
• Hair length is determined by a variety of factors, including genetics and hormones. Men's hair typically doesn't grow as long as women's hair. The maximum length for men is about 40 to 50 centimeters, whereas for women it is 70 to 80 centimeters.
• The hair growth cycle is an important aspect of hair biology. All hair strands are replaced by new ones within two to six years. This process, known as the hair growth cycle, occurs up to 12 times in a person's lifetime. After the twelfth cycle, new hair growth ceases in that area.
• Hair color and texture also play an important role in determining the number of hairs on a person's head. Blondes have the most hair, with around 140,000 strands, followed by brunettes with approximately 100,000 hairs. Redheads have the least, with only about 85,000 hairs.
• Hair grows faster in the summer than in the winter, and women are more likely to have gray hair than men, and often at an earlier age. Additionally, cutting your hair does not affect the rate of hair growth.

Rules for Hair on Passport Photos

When it comes to passport photos, there are a few rules to keep in mind regarding hair. Your hair can be styled in any way you like, as long as it is a good likeness of you.

However, the hair should not cover your eyes or eyelids. If your hair falls over your ears, make sure the earlobes are visible so that the width of your face can be accurately determined. If you have a large head of hair, it is not necessary to depict all of it in the passport photos.
