70–80 hairs per day is normal, especially when washing or brushing hair. However, if noticeably larger amounts are coming out regularly, it usually signals that something internal needs to be investigated by a qualified trichologist.
Hair naturally cycles through growth, rest and shedding phases. Because many loose hairs collect on the scalp between washes, it can look alarming when they release in the shower all at once. In most healthy scalps, this daily shedding is simply part of renewal, and the hair replaces itself continuously.
When the shedding becomes heavier or persistent, one common cause is diffuse hair loss, also known as telogen effluvium. This type of hair loss affects the entire scalp evenly rather than forming bald patches. Importantly, this condition does not lead to permanent baldness because the follicles remain active and are capable of regrowth.
There are two main types of diffuse hair loss.
Acute diffuse hair loss, it develops quickly and usually lasts less than three months. Shedding often increases suddenly and may follow a major stress to the body. Common triggers include high fevers exceeding 39.5°C, food poisoning, starting or stopping oral contraceptives, pregnancy or pregnancy cessation, surgery, rapid weight loss or beginning a restrictive diet. In most cases, acute shedding is self-correcting and resolves naturally without medical treatment once the body stabilises itself.
Chronic diffuse hair loss behaves differently. You will notice the signs around three months after the original trigger and it continues gradually for six months or longer. It is often linked to nutritional deficiencies, anaemia, hormonal imbalances, underlying medical issues, or reactions to ongoing medications. This form does not self-correct. Hair shedding will usually continue until the underlying cause is properly identified and addressed through professional assessment and targeted care.
If shedding feels excessive or sudden, a scalp assessment in Brighton can clarify the cause.
