The American Academy of Dermatology says that hair grows about 1/2 inch per month on average. That’s a grand total of about 6 inches per year for the hair on the head. Hair growth will depend on age, specific hair type, overall health, other health conditions.

Hair grows in three stages, and each strand of hair follows its own timeline. These three stages are, anagen: active growth phase of hair that lasts 2-8 years, catagen: transition phase where hair stops growing, last 4-6 weeks, telogen: resting phase where hair falls out, lasts 2-3 months

The average scalp has 90-95 percent of the hair follicles in the anagen phase. This means about 5-10 percent are in the telogen phase, which accounts for the 100-150 hairs that fall out every day.

How long the anagen phase lasts depends on how long the hair is and if the cells in the follicle base are continuing to multiply and become hair cells. Hair grows because matrix cells shed some of their structure as they reach the upper follicle. The shed structure combines with keratins to form hair strands that exit the skin’s surface.

Hair is made up of keratin and dead skin cells. While there’s no direct method to make the hair grow faster overnight, there are steps people can take to keep the hair healthy and long. Talk to your doctor before trying supplements such as biotin, keratin, or other nutritional supplements. They may interact with medications and cause unintended side effects.

While many companies promote vitamins or supplements for hair growth, they don’t always directly affect hair length. But the body does require a lot of energy to make the hair grow. Missing out on balanced meals and nutrients can affect hair growth.
