WHY AM I LOSING MORE HAIR THAN USUAL?

This article explores why hair shedding can suddenly increase, what may be behind the change, and when it deserves closer attention.
Seeing more hair than usual in your brush, shower or on your pillow can be unsettling.
Hair shedding is an intrinsic part of the hair cycle. A certain amount of daily loss is expected, as individual follicles move continuously through their own phases of growth, transition and rest.
What matters is a meaningful departure from your usual pattern.
A sudden increase in shedding can follow a temporary disruption to the hair cycle, significant physical or psychological stress, illness, hormonal change, nutritional deficiency, medication or an underlying condition.
There is also a fundamental distinction between excessive shedding and progressive hair loss.
More hair leaving the scalp does not necessarily mean the follicles have permanently lost their capacity to produce hair. Conversely, progressive thinning can develop without a dramatic increase in visible shedding.
Understanding which process is taking place is where a more informed approach begins.
HOW MUCH HAIR SHEDDING IS NORMAL?
Hair does not grow continuously from every follicle at the same time.
Each follicle moves through a repeating cycle. The anagen phase is the active growth stage, followed by catagen, a brief transitional period, and then telogen, the resting phase. The mature hair is eventually released, allowing the follicle to begin another growth cycle.
Because thousands of follicles occupy different stages simultaneously, some daily shedding is inevitable.
The amount you notice can also be influenced by your washing routine. If you wash your hair every few days, several days' worth of naturally shed hairs may be released during one wash, making the volume appear considerably greater than it actually is.
The more meaningful measure is your personal baseline.
A sustained increase in shedding, a visibly thinner ponytail, a widening part or a noticeable reduction in overall density carries more significance than the number of hairs seen after a single wash.
Hair changes are best understood as a pattern over time.
WHY CAN HAIR SHEDDING SUDDENLY INCREASE?
One of the most recognised causes of sudden increased shedding is telogen effluvium.
Telogen effluvium occurs when a greater proportion of follicles than usual shifts from the active growth phase into the resting phase. The increased shedding generally becomes apparent some time after the event that disrupted the cycle, rather than immediately afterwards.
This delayed timing can make the original trigger surprisingly difficult to identify.
A significant illness, high fever, surgery, substantial weight loss, restrictive dieting or psychological stress can precede an episode of telogen effluvium. Hormonal changes, including those associated with childbirth and menopause, can also influence the hair cycle. Certain medications, endocrine conditions and nutritional deficiencies may play a role as well.
The important point is that the trigger and the shedding are not always simultaneous.
You may notice the change in your hair long after the event itself has passed.
Other forms of hair loss can have very different mechanisms. Alopecia areata, for instance, is an autoimmune condition that can cause sudden, often patchy hair loss. Traction alopecia can develop when repeated tension places prolonged stress on the hair follicles.
Sudden shedding is therefore a symptom rather than a diagnosis. Its appearance alone cannot establish the underlying cause.
IS IT SHEDDING OR IS YOUR HAIR ACTUALLY THINNING?
This distinction is fundamental.
With excessive shedding, more hairs are leaving the scalp than usual, but the follicles may remain capable of producing healthy hair. Telogen effluvium, for instance, is generally a temporary form of excessive shedding in which new hair continues to grow.
Progressive thinning follows a different trajectory.
In androgenetic alopecia, genetically susceptible follicles respond to androgen signalling in a way that progressively reduces the size and productive capacity of the follicle.
Dihydrotestosterone, or DHT, plays an important role in this process. In susceptible follicles, its influence is associated with a shortening of the anagen phase and progressive follicular miniaturisation. The resulting hairs become finer and shorter, gradually reducing visible density.
This can occur without dramatic quantities of hair appearing in the shower.
The first signs may instead be a widening part, reduced density around the crown or a gradual change in hair calibre.
Shedding and miniaturisation can also coexist.
That is why counting the hairs that fall is only one part of understanding what is happening. Density, hair calibre, parting and the pattern of change often reveal considerably more.
