Hair growth may seem simple from the outside, but every strand of hair follows a natural biological cycle. Hair follicles move through different phases of growth, transition, rest, and shedding. Understanding these stages—anagen, catagen, and telogen—can help you better understand why hair grows at different rates and why some shedding is completely normal.
At Just For Hair, also known as OP Hair Salon, located at 1170 W 135th St, Overland Park, KS 66221, United States, we believe that understanding how hair behaves is an important part of creating a thoughtful, personalized hair-care routine.
What Is the Hair Growth Cycle?
Hair doesn’t grow continuously at the same rate forever. Each follicle independently moves through a repeating cycle.
The three primary stages are:
- Anagen — the active growth phase
- Catagen — the transition phase
- Telogen — the resting phase
After the resting phase, the old hair may shed and the follicle can eventually return to the growth phase.
The length of each stage varies from person to person and can also differ between individual follicles.
1. Anagen: The Active Growth Phase
Anagen is the phase in which the hair follicle is actively producing a hair strand.
For scalp hair, this is typically the longest stage of the cycle. The longer a follicle remains in anagen, the longer the hair has an opportunity to grow.
Factors such as genetics, age, overall health, and other biological influences can affect the length of the growth phase.
This is one reason why some people can grow very long hair while others naturally reach a shorter maximum length.
Caring for Hair During the Anagen Phase
While you can’t control your genetic growth cycle through salon treatments, you can protect the hair you already have.
Gentle brushing, appropriate conditioning, heat protection, and minimizing unnecessary chemical or mechanical damage can help maintain the appearance and manageability of growing hair.
2. Catagen: The Transition Phase
After the active growth period, the follicle enters catagen, a relatively short transition stage.
During this phase, the follicle reduces its growth activity and begins transitioning toward a resting state.
Hair growth slows or stops temporarily as the follicle prepares for the next phase.
Because catagen is much shorter than anagen, it represents only a small portion of the overall hair cycle.
3. Telogen: The Resting Phase
Telogen is the resting stage of the hair cycle.
During this phase, the follicle is inactive for a period of time while the existing hair remains in place. Eventually, the old hair can shed, making room for a new growth cycle.
Seeing some hair in your brush, shower drain, or on your clothing can therefore be a normal part of the hair cycle.
What Is Exogen?
You may also hear the term exogen when discussing hair biology.
Exogen refers to the shedding process in which the existing hair is released from the follicle. It is often discussed as part of or alongside the telogen stage.
This helps explain why normal hair shedding doesn’t necessarily mean that your hair is becoming thinner.
Why Does Hair Shedding Happen?
Because individual follicles are at different stages at different times, your entire scalp doesn’t normally shed its hair simultaneously.
Some follicles may be actively growing while others are transitioning, resting, or shedding.
The result is a continuous cycle of growth and normal shedding.
However, sudden or substantial changes in shedding can have many possible causes and should be evaluated by a healthcare professional.
How Fast Does Scalp Hair Grow?
Scalp hair commonly grows around 1 centimeter per month on average, although the actual rate varies among individuals.
Growth can be influenced by genetics, age, health, hormones, nutrition, and other factors.
Because growth happens gradually, patience is important when working toward longer hair.
Why Hair Length Depends on More Than Growth
You may wonder why your hair doesn’t seem to get longer even though it continues to grow.
One reason is breakage.
If hair is growing from the follicle but breaking at the ends because of heat, chemical processing, tension, or mechanical damage, you may struggle to retain length.
This is why hair-length goals require both growth and length retention.
The Role of Professional Hair Care
Salon services don’t change the biological phases of your hair follicles, but professional hair care can help you protect the hair you already have.
A stylist can help you:
- Choose haircuts that support your desired length.
- Manage split ends and visible damage.
- Develop a heat-styling routine.
- Select products appropriate for your hair texture.
- Plan color services with hair condition in mind.
- Reduce unnecessary mechanical stress.
- Create a manageable long-term maintenance schedule.
Healthy-looking hair is often about protecting the strands while they naturally move through their growth cycles.
Nutrition and Hair Growth
Hair follicles require nutrients to function normally, which is one reason overall nutrition is important for general hair health.
A balanced diet that provides adequate protein, vitamins, minerals, and other essential nutrients supports overall wellness.
However, hair supplements aren’t a universal solution for hair-growth concerns. If you experience unusual shedding or thinning, it’s better to discuss the issue with a qualified healthcare professional before taking supplements.
When Hair Shedding May Need Professional Evaluation
Normal shedding is different from sudden or excessive hair loss.
Consider speaking with a dermatologist or healthcare professional if you notice:
- Sudden increases in shedding
- Noticeable thinning
- Bald patches
- A widening part
- Significant changes in hair density
- Scalp pain, inflammation, or persistent itching
- Hair loss that continues or worsens
A healthcare professional can investigate potential underlying causes and recommend appropriate treatment when necessary.
How Your Hair-Care Routine Supports Length Retention
While you can’t simply force a follicle to remain in the anagen phase, you can take steps to protect the hair produced during that phase.
A practical routine may include:
Gentle cleansing → Conditioning → Careful detangling → Heat protection → Minimal unnecessary tension → Regular trims → Professional maintenance
The objective is to reduce preventable damage so that more of your naturally growing hair can remain strong and manageable.
Understanding Your Hair Helps You Care for It Better
The hair growth cycle explains why hair growth and shedding are ongoing processes rather than overnight changes.
Anagen is active growth.
Catagen is the transition.
Telogen is the resting stage.
Exogen describes the shedding process.
Understanding these stages can help you set realistic expectations about hair growth and recognize why healthy hair care is largely about protecting the strands you already have.
