How Long Does Hair Grow In A Week, Month, And Year?

According to The American Academy of Dermatology, our hair grows 0.5 inches (1.27 cms) per month on average. That’s about 6 inches per year.

However, there are several factors that can affect this growth. This includes your age, hair type, stress levels, genes, overall health, and certain medical conditions. That said, there are some ways that can help you grow your hair faster.

In this article, we’ll talk about how much our hair grows in a week, month, and year. We’ll also talk about different ways to boost hair growth. Let’s dive right in.

How Long Does Hair Grow In A Week, Month, & Year?

On average, your hair will grow 0.125 inches (or 3 mm) in a week, 0.5 inches in a month, and 6 inches in a year. However, this is different for everyone.

If you’re blessed with good genes and take good care of your hair, you can expect your hair to grow at a faster rate than this. On the other hand, if you lead a stressful lifestyle, do not eat well, and have certain medical conditions, your hair growth could be slower. Overuse of heat styling tools can also down hair growth.

Luckily, there are ways in which you can boost hair growth.

Hair Growth Cycle

Before we dive into how to make your hair grow faster, it’s vital to understand the human hair growth cycle. There are three main stages of hair growth:

Anagen Phase

This is the active growth phase of hair that typically lasts two to seven years. On average, there are about 100,000 hair follicles on the human head. At any given time, about 90 to 95 percent of all these follicles are in the anagen phase.

Catagen Phase

Also known as the transition stage, this phase typically lasts 4 to 6 weeks. During this period, the hair stops growing, and the hair strand will slowly move up in the follicle.

Telogen Phase

The telogen phase, also known as the resting phase, is the stage where your hair starts falling out. This period usually lasts around 2 to 3 months.

On average, humans shed 100 to 150 strands of hair every day. Those strands are in the telogen phase.

How Can You Make The Anagen Phase Last Longer?

In order to get longer hair, the cells in our follicle base need to multiply and turn into hair cells. That will make the anagen phase last longer.

Unfortunately, researchers have not been able to find out what triggers human bodies to turn on the anagen phase. In short, we don’t have enough information on how we can “turn on” and make the anagen phase last longer.

However, there are things that you can do to promote healthy hair growth.

How To Promote Healthy Hair Growth?

There are a lot of things that you can do to promote healthy hair growth. These include:

Use Essential Oils

Using oils such as jojoba oil, argan oil, coconut oil, etc. can help boost hair growth. According to a study, pumpkin seeds can increase hair count in men who have suffered a significant hair loss.

Besides, these oils are very beneficial for hair as they’re packed with moisturizing ingredients. 

Eat A Balanced Diet

You need to eat well if you want healthy hair growth. Take foods rich in zinc, omega-3, vitamin C, iron, vitamin D, and biotin. While it’s best that you take these vitamins and nutrients from your diet, supplements can also help.

Keratin Supplements Can Help

Keratin is a protein that’s found in our hair. It can strengthen your follicles to make them less susceptible to breakage. So, you can consider investing in keratin supplements. According to a study, people who took keratin supplements saw a 12.5 percent reduction in hair loss. That’s an impressive number.

Try Laser Hair Growth Devices

If you’re suffering from androgenetic alopecia, then eating well or taking keratin supplements probably won’t help. However, you can use a laser hair growth device to combat hair fall. Laser devices emit photons into scalp tissues, which are then absorbed by weak cells. This, in turn, boosts circulation and promotes hair growth.

A study of 42 participants found that LLLT (Low Laser Light Therapy) provided a 39% increase in hair growth over a period of 3 months. Best of all, it’s safe to use on both men and women. All this makes laser devices an attractive hair loss treatment option.

Try Protein Masks

Protein not only strengthens your hair but also makes your hair grow faster while protecting it from environmental damage. Try hair masks that contain protein-rich ingredients such as eggs, yogurt, coconut milk, avocado oil, honey, etc. to boost hair growth.


On average, your hair will grow 15 cms in a year and 1.3 cms in a month. But this can vary depending on a lot of things. While most of the factors that determine hair growth are out of our control, there are still things that can boost hair growth.

This includes eating well, leading a healthy lifestyle, drinking plenty of water, using essential oils, and taking supplements. If you follow the steps, you can definitely grow your hair at a much faster rate.
