Finding hair on your pillow, in your brush, or in the shower is a common experience that can cause concern. Am I losing too much hair? Is this amount normal? It’s natural to wonder if the hair loss we’re experiencing is expected or if it’s a warning sign that needs attention. At D’Atri Medicina Capilar, we understand your concerns and want to help you differentiate between natural hair renewal and a problem that requires diagnosis and treatment.
The key question many people ask is: How many hairs do you normally lose per day? The answer, supported by trichology (the science that studies hair), is that losing between 50 and 150 hairs a day is considered completely normal.This figure may sound high, but it represents a tiny fraction of the total number of hairs on our heads (between 100,000 and 150,000 on average) and is a natural consequence of our hair’s life cycle.
Understanding the Hair Life Cycle: Why Does Hair Fall Out?
To understand why hair loss, it is essential to understand the hair life cycle. Each hair on our head goes through different phases, and not all of them are in the same stage at the same time. It is important to remember that the hair itself is a lifeless structure; what is alive is the hair follicle,the structure in the skin where hair grows.
This cycle is mainly divided into three phases:
- Anagen (Growth) Phase: This is the longest phase, lasting between 2 and 7 years. During this time, the hair actively grows from the follicle. Approximately 90% of our hair is in this phase at any given time.
- Catagen (Transition) Phase: This is a short phase, lasting about 2-3 weeks, where hair growth stops. The follicle shrinks, and the hair prepares to shed. This is a stage of “programmed cell death” for that particular hair.
- Telogen Phase (Resting and Shedding): It lasts about 3 months. The hair no longer grows and remains loosely anchored in the follicle while, underneath, a new hair in the anagen phase begins to form and pushes the old one out. Eventually, the telogen hair falls out. It’s normal for about 10-15% of our hair to be in this phase, which explains the 50-150 hairs we lose every day.
Therefore, that number of hairs that fall out per day is mostly hair that has completed its natural cycle and is being replaced by a new one.
Normal Fall or Warning Sign? Key Differences
Knowing that losing up to 150 hairs a day is normal is reassuring, but how do you know if your particular case requires attention? Here are some clues:
- Look at the shed hair: Hair that sheds naturally (in the telogen phase) usually has a small whitish bulb at the root. If you see many hairs without this bulb, they could be splitting due to cosmetic damage (harsh dyes, straightening, excessive heat use) and not falling out from the root. This requires different care.
- Sustained shedding:If you consistently notice a shedding of significantly more than 150 hairs per day (for example, large clumps in the shower or when combing your hair) for several weeks, this could indicate a problem such as Telogen Effluvium.
- Progressive thinning:If you notice your hair becoming finer, your scalp becoming more transparent than before, or your hairline receding (a receding hairline), you could be facing Androgenetic Alopecia. This type of alopecia, the most common, is characterized by follicle miniaturization (increasingly thinning and shorter hair) due to hormonal and genetic factors, rather than sudden massive hair loss. It is crucial to detect the presence of hairs of different diameters in the same area.
- Specific areas of hair loss: The appearance of “patches” or circular areas of hair loss can be a sign of Alopecia Areata, an autoimmune condition.
- Itching, flaking, or pain:These scalp symptoms can accompany certain types of alopecia (especially scarring) and should always be evaluated by a specialist.
It’s common to wonder how many hairs fall out in the shower (men or women) or how many hairs fall out when bathing. It’s normal to notice more hair in these situations because the water and massage help loosen hairs that were already in the telogen phase (ready to fall out). What matters is not so much the exact amount in a single wash, but the total daily average and whether it increases dramatically or is accompanied by other signs.
Factors That Can Increase Hair Loss
If you notice a temporary but significant increase in hair loss (more than 150 hairs per day), it may be due to Telogen Effluvium. This occurs when an increased number of follicles prematurely enter the resting (telogen) phase due to a trigger. Some common factors include:
- Intense physical or emotional stress: Stress is one of the main causes behind hair loss. These include surgeries, illnesses with high fever, accidents, the loss of a loved one, and periods of high work or personal stress.
- Hormonal changes: Postpartum, starting or stopping birth control, thyroid problems.
- Nutritional deficiencies: Lack of iron (anemia), zinc, biotin, protein, or essential vitamins. Very restrictive diets.
- Medications:Some medications can have hair loss as a side effect.
- Systemic diseases.
The good news is that, in most cases of telogen effluvium, once the underlying cause is resolved, hair loss usually normalizes within a few months. However, a correct diagnosis is essential to rule out other conditions.
When to Consult a Hair Medicine Specialist?
If you have questions about your hair loss, if you notice any of the warning signs mentioned above, or if you simply want a professional evaluation for your peace of mind, it’s time to consult. At D’Atri Medicina Capilar, we believe in the importance of early diagnosis. The sooner the cause is identified, the more effective the solutions can be.
Don’t rely on myths. It’s important to know that shampoo does NOT cure baldness. While a good shampoo helps keep the scalp clean and healthy, creating an environment conducive to growth, it cannot reverse established alopecia or stop significant hair loss on its own. There are no magic or immediate solutions; Hair treatments require time, consistency, and medical follow-up.

- Regenerative therapies: Capillary mesotherapy, Platelet Rich Plasma (PRP).
- Hair implant with FUE Technique: For cases of advanced androgenetic alopecia or other permanent alopecia. This minimally invasive technique redistributes your own follicles from a donor area (usually the nape of the neck, which is hormone-resistant) to the recipient area, without linear scarring, with local anesthesia and a quick recovery. It is essential to understand that the implant does not replace basic medical treatment in cases such as androgenetic alopecia, but rather complements it to achieve greater density.
In addition, for medical professionals interested in specializing, we offer excellent training courses in the FUE Techniquewith practice on real patients.
