We’ve all been there: That one trip to the salon where things got a little too scissor happy. The stylist promises just to cut off your split ends. You wait patiently watching your hair fall to the floor and as soon as your chair is swiveled around to reveal the results of the snip, you realize they've cut off more than you anticipated. You grab your phone and furiously Google "how fast does hair grow??" with one too many question marks. Fortunately, hair grows back ... it's just a matter of how long it'll take.

As it turns out, much like the rest of the body, healthy hair is a reflection of overall health. Hair wellness, including the hair growth process, is a holistic process that starts from within.

How Fast Does Hair Grow?

The average rate of hair growth per year is six inches for most people, which translates to half an inch per month. According to The American Academy of Dermatology, all the hair follicles we will have in our lifetime are already in place when we are born. We enter the world with approximately 100,000 hair follicles on the scalp. Hair has two distinct components: The hair follicle, which is in the skin, and the hair shaft, which is visible above the scalp.

Hair does grow relatively quickly — the only faster growth within the human body is bone marrow. Hair growth tends to occur more quickly in males than it does in females.

There are many factors that influence how hair grows, including:

Now that you know how much hair growth you can expect over the next year, let's find out exactly how hair grows, how to grow your hair and how to integrate hair care into a self-care routine.

Exactly How Hair Grows

The hair growth cycle consists of four different stages:

  • Anagen
  • Catagen
  • Telogen
  • Exogen

Anagen Phase

Anagen is the hair growth phase; during this phase, new hair growth pushes old hair up and out of the hair follicle. This phase is about two to six years long in duration. The good news is that approximately 90% of your hairs are in this anagen phase at any given time. The bad news is that a shorter anagen phase can stunt hair growth and the amount of hairs in this phase continues to decline as we age.

“As we age, some hair follicles do slow or stop growing,” said Michelle Henry, MD, Clinical Instructor of Dermatology, Weill Cornell Medical College. “This is why many people may notice hair thinning or baldness with age.” 

Other factors play a role in stunting hair growth and damage. This can include the overuse of heat styling or using an improper brush on wet hair, leading to split ends on strands.

"Many people aren't aware that certain surgeries and/or anesthesia impact the rate of hair growth," said New York City Hairstylist Jasmine Anna Galazka. These procedures may stunt the rate in which the hair does grow, Galazka said.

Catagen Phase

Next is the catagen phase, when hair growth stops, acting as a transitory phase from the growth cycle to the hair shedding process. Those with thinning hair may have a disproportionate amount of hair during this phase, preventing hair growth and leading to hair loss. The catagen phase is typically around three weeks long but can be as long as four months.

Telegen Phase

The telegen phase is when the body is preparing to shed hair and begin a new growth cycle. This phase lasts about three months.

Exogen Phase

Finally, the exogen phase is the shedding process, in which it is normal to experience hair loss of about 100 hairs each day. While that sounds like a lot, remember we have about 100,000 hair follicles. This is the shortest of the hair growth cycles, lasting only a few days.

How Hormones & Ethnicity Impact Hair Growth 

“A decrease in estrogen hormones (often with age) as well as increase in thyroid hormones can lead to hair loss,” Dr. Henry explained. “ Mental and/or physical stress can also trigger a hair loss condition called telogen effluvium which can cause excessive shedding for many months.” 

And, while many people tend to feel that their hair grows faster in the summer months, there is little conclusive evidence or research-backed studies that link increased hair growth to any particular season, explains the doctor. Hair tends to grow based on its cycles, rather than seasons.

According to The International Journal of Dermatology, ethnicity can also play a role in how quickly one's hair grows. The study reported racial differences in hair growth, citing the average hair growth rate of Asian women was nearly six inches per year. African-American women had the slowest growth at four inches per year whereas Caucasian women experienced about five inches of hair growth per year.

You Are What You Eat

The body is a mirror of what is going on within it. Adopting a nutrient-dense diet, including protein, fatty acids, oils rich in omega 3 and fatty acids, vitamins and minerals, supports overall health and healthy hair. Maintaining a vitamin- and mineral-rich diet can help stimulate the natural production of natural oils on both the hair and scalp and may also help in preventing or reducing split ends and hair damage.  

Inflammatory ingredients such as excess sugar can hinder the absorption of protein, ultimately leading to hair thinning, hair loss, damage and breakage, so reducing such ingredients can also be helpful for healthy hair. Incorporating the regular use of supplements such as a daily gummy vitamin containing folic acid, zinc, selenium, biotin or Vitamin D, may also help nourish hair, especially for those with deficiencies.

Opt for hair care products that include powerful plant-based phyto-actives that address both the symptoms and causes of visible hair thinning and hair loss. Detangle your hair only when your hair is damp and saturated with a revitalizing conditioner to minimize friction-induced breakage or damage.
