Hair loss is often associated with something sudden, almost obvious. In reality, the first signs are often progressive and subtle. They set in gently, to the point where we sometimes get used to them without really noticing.
The first signs to look for
The most common first sign is an increase in daily hair loss. You notice more hair on your brush, in the shower, or on your pillow, without necessarily immediately understanding whether it's normal or not.
Another frequent indicator is a loss of density. Hair appears less voluminous, finer, and certain areas of the scalp become slightly more visible, particularly along the part.
You might also notice a slowdown in regrowth. Hair falls out, but seems to be replaced less quickly, giving an impression of less dense hair over time.
Situations that should raise concern
Hair loss becomes more concerning when it persists over time with no visible improvement. If the loss remains significant for several weeks or months, it is generally advisable not to wait any longer.
It's also helpful to have a simple benchmark. Losing between 50 and 150 hairs per day is considered normal. This corresponds to hair in the telogen phase, the natural shedding phase of the hair cycle, which falls out to make way for new growing hairs. On average, about 90% of hair is in the growth phase and 10% in the shedding phase.
However, when the loss exceeds this threshold, it can become a real warning sign. More significant hair loss, visible daily, is often the right time to intervene before the situation becomes established.
It's also important to remember that perception can vary. The same amount of lost hair can seem more impressive on long or thick hair than on short or fine hair.
Sudden and diffuse hair loss, with no apparent reason, can also be a signal to consider, especially if it occurs after a hormonal change, significant stress, or prolonged fatigue.
Finally, when you observe thinning areas on the top of the scalp or temples, it is best to act quickly.
When to consult?
It is recommended to consult when hair loss becomes persistent and visibly impacts overall density. The goal is not to wait for an extreme situation, but to intervene at the right time.
A professional opinion helps identify the exact cause of the hair loss, whether it is hormonal, stress-related, due to a deficiency, or an imbalance of the scalp. The earlier the diagnosis, the more effective the solutions.
Hair loss is often progressive, and the first signs are easily missed. The most important thing is to observe the evolution over time and not wait for the situation to become established before taking action.
