Understanding your hair’s growth cycle can help you grow and maintain longer, stronger strands. The four stages of hair growth: anagen (growth), catagen (transition), telogen (resting) and exogen (shedding) are different phases requiring their own attention and hair care. If you’re ready for your longest, strongest head of hair yet, you’re in the right place. Because we’re breaking down everything you need to know about the hair growth cycle- including tips for healthy hair and the best products for each phase in the cycle.

Key Takeaways

Breaking Down Hair Growth

The hair growth cycle has four stages: anagen (growth), catagen (transition), telogen (resting), and exogen (shedding).
Each phase affects how your hair grows, rests, and renews itself.
Factors like stress, diet, and hormones can disrupt this natural cycle and cause excessive shedding or thinning.
Support your hair through every phase with balanced nutrition, gentle care, and scalp-focused products.
Davines products help maintain healthy growth by stimulating the scalp, strengthening strands, and restoring balance throughout the cycle.

Basic Understanding of the Hair Growth Cycle

Understanding each stage of the hair growth cycle and its impact on your hair’s health will help you build the best hair care routine for your strands. The science behind the hair growth cycle goes like this. Your hair grows in four different stages. Strands start out in the first one, known as the anagen phase, where they spend three to five years growing. Then they move into a transitional stage for about ten days, called the catagen phase. The next stage your strands go through is the telogen phase, going dormant for up to four months.

The last stage of the hair growth cycle is the exogen phase, when strands are finally shed from the follicle, before starting in anagen all over again.

Each Hair Growth Cycle Stage

Hair grows in four distinct stages. The first three phases- anagen, catagen, and telogen- are the actual growing period of the strands. The last, or exogen phase is when the old strand finally sheds from the follicle. Each phase has its own timeline, affected by age, nutrition, and overall health. Let's take a deeper dive into each phase of the hair growth cycle below.

Anagen: The Phase of Active Hair Growth

Your hair starts off in the anagen phase, where cells are rapidly dividing for active growth. During this phase, your hair grows around half an inch a month, or about 6 inches a year. Anagen lasts an average of 3-5 years.

Catagen: The Shortest Transition Stage of Hair Growth Cycle

After anagen, your hair enters a short transitional phase called catagen. During this stage hair follicles shrink and detach from their blood supply. The catagen phase signals the end of active hair growth and lasts around 10 days.

Telogen: The Resting Phase Where Hair Can Shed

The next phase in the hair growth cycle is telogen, also known as the resting stage. Here, strands remain in the follicle, but are no longer actively growing. This period of dormancy lasts from 3-4 months before shedding begins.

Exogen: The Shedding Phase of Hair Growth Cycle

Next up is exogen, and if you’ve been wondering ‘what is the phase of the hair growth cycle in which the hair can shed?’ this is it. In this final stage, strands are released from their follicles and fall out, before the whole cycle begins again.

Factors Influencing the Hair Growth Cycle

Remember that hair follicles are independent of each other and have their own growth cycles, so new hairs are introduced as the previous cycle sheds. A disruption in this cycle, however, can force more follicles than normal enter the telogen resting phase, causing noticeable hair loss or thinning. Hair loss shows up as one of the following disruptions-

Handling Disruptions in the Hair Growth Cycle

Androgenetic alopecia

A widening of the hair’s natural part strongly links to both genetics and hormones and is more common with age

Alopecia areata

An autoimmune disorder where the immune system attacks hair follicles, leading to sudden, round patches of hair loss

Telogen effluvium

Excessive hair shedding that temporarily occurs after a stressful event, hormonal imbalance or certain medications

Traction alopecia

Hair loss caused by prolonged tension from tight hairstyles that pull on the hair, leading to permanent follicle damage

Maintain your hair health during all phases of the hair growth cycle and handle disruptions by managing your stress, eating a balanced diet rich in vitamins and minerals, using high quality products made from natural ingredients on your hair and scalp, limiting heat and harsh chemicals and avoiding tight hairstyles.

Personalizing Your Hair Care Routine According to Your Hair Growth Cycle

A healthy hair care routine recognizes each phase of the hair growth cycle. In addition to using the right formulas for your hair type, your routine should focus on stimulating the scalp for the hair in anagen, managing the ones in catagen and minimizing breakage during the telogen phase. Use gentle detangling practices to help with shedding of strands in the exogen phase, and focus on scalp health throughout the cycle to support healthy hair growth at each stage.

FAQs

Still have questions about the hair growth cycle? We’re breaking down some of your most pressing hair growth questions and answers. Let's take a look below.

How long does it take for hair to go through a cycle?

The full hair growth cycle of growing, resting, and shedding typically lasts between 2 to 7 years, depending on the individual. Hairs spend most of their time actively growing in anagen, which can take anywhere from 2 to 6 years. Each hair follicle goes through its own cycle over this timeframe meaning strands are constantly in different stages, all the time

What stage is the shortest hair growth cycle?

You know that anagen is the longest, so what stage is the shortest hair growth cycle? If you guess the transitional phase between active growth and resting, or the catagen phase, you’d be correct. The shortest stage of growth typically only lasts around 10 days.

How long does a hair shedding cycle last?

The hair shedding phase, or exogen, is the final stage of the hair growth cycle. It’s during this phase, where hair strands are shed and released from the hair follicle. The entire shedding process can last anywhere from 2-5 months.
