Hair Shedding:
What's Normal and When to Pay Attention
Finding hair in your brush, shower drain, or on your pillow can be concerning, but some degree of shedding is completely normal. In fact, most people lose between 50 and 100 hairs every day as part of the body’s natural hair growth cycle.
Because we shed hair gradually throughout the day, it’s often more noticeable when washing, brushing, or styling your hair. For many people, daily shedding is simply a sign that healthy new hair growth is making room for older strands to fall away.
The Natural Life Cycle of Hair
Every strand of hair follows a continuous growth cycle made up of three phases:
Growth Phase (Anagen)
This is the active growing stage of the hair follicle. About 85–90% of your hair is typically in this phase at any given time. Hair can remain in the growth phase for several years before transitioning to the next stage.
Transition Phase (Catagen)
During this brief phase, hair growth slows and the follicle begins preparing for rest. Only a small percentage of hairs are in this stage at any one time.
Resting and Shedding Phase (Telogen)
This is the stage where older hairs naturally separate from the follicle and are shed. Approximately 10% of your hair is in the shedding phase at any given time, making daily hair loss a normal part of healthy hair renewal.
When Hair Loss May Be More Than Normal Shedding
While everyday shedding is expected, a sudden increase in hair loss or noticeable thinning may signal that something else is affecting the hair growth cycle.
Signs that may warrant further evaluation include:
- Excessive hair shedding for several weeks or months
- Widening of the hair part
- Noticeable thinning around the crown
- Bald patches or areas of reduced hair density
- Increased hair accumulation during brushing or washing
Understanding the cause of hair loss is the first step toward finding an appropriate solution.
The Connection Between Stress and Hair Loss
Physical and emotional stress can have a significant impact on hair growth. One common form of temporary hair loss is called telogen effluvium, which occurs when stress causes more hair follicles than usual to enter the shedding phase.
Potential triggers may include:
- Significant illness or infection
- Major life events
- Emotional stress
- Surgery or injury
- Rapid weight loss
- Hormonal changes
Hair shedding related to stress often appears several weeks or even months after the triggering event, making it difficult to identify the cause immediately.
The good news is that this type of hair loss is often temporary, and normal hair growth may return once the underlying trigger is resolved.
Common Types of Hair Loss
Hair loss can occur for a variety of reasons, and not all forms are the same.
Pattern Hair Loss
Also known as androgenetic alopecia, this is the most common form of hair loss in both men and women. Genetics, age, and hormonal influences all play a role. Women often notice thinning near the crown or a widening part, while men commonly experience a receding hairline.
Traction Hair Loss
Repeated tension from tight hairstyles such as braids, ponytails, extensions, or locs can place stress on hair follicles and contribute to hair loss over time.
Alopecia Areata
This autoimmune condition causes the body’s immune system to attack healthy hair follicles, leading to patchy hair loss that can vary in severity.
Hair-Pulling Disorders
Conditions such as trichotillomania involve repetitive hair pulling and can result in noticeable thinning or bald patches.
Taking the Next Step
Hair health is influenced by many factors, including genetics, hormones, nutrition, stress levels, and overall wellness. If you’re experiencing increased shedding or noticeable thinning, speaking with a healthcare provider can help identify possible causes and discuss treatment options that may be appropriate for your needs.
The Bottom Line
Not all hair loss is cause for concern. Daily shedding is a normal part of the hair growth cycle, and most people lose dozens of hairs each day without noticing a change in hair density. However, sudden increases in shedding, thinning, or patchy hair loss may be worth discussing with a healthcare professional to better understand what’s happening and what options are available.
