Hair grows at an average rate of about half an inch per month (or six inches a year) . However, some outside factors can contribute to faster growing hair, and they arent all positive. These include the use of anabolic steroids, taking testosterone or applying topical stimulants such as minoxidil (found in Rogaine) which is often used to treat male pattern baldness. On the other hand, faster growing hair on the scalp can be a sign of something good, such as pregnancy, which usually causes a surge in estrogen. Other factors that can impact hair growth include:

• Heredity: The rate of hair growth varies from person to person and is mainly influenced by genetics.

• Chronic stress: Research published by the National Institutes of Health suggests that chronic stress can impact hair growth, although the connections arent well understood.

• Imbalance of male hormones: An excess of androgens could be a reason for faster hair growth in women.

• Thicker hair strands: Thicker hair (>60 µm) grows generally faster (11.4 mm per month) than thinner (20-30 µm) hair (7.6 mm per month) .

• Gentle and regular brushing: Experts believe that gentle and regular brushing can stimulate hair growth.

• Pregnancy: During pregnancy, hair is in its growth stage, which can cause faster hair growth.

• Seasonal changes: Hair growth may be different in different seasons. For example, in summer, hair growth may be faster.

Its important to note that while some of these factors can contribute to faster hair growth, there is no direct way to make hair grow faster overnight. However, keeping hair healthy with a balanced diet and good hydration can help promote healthy hair during the anagen phase.
