Why Is My Hair Falling Out in the Shower? 9 Common Causes (and What You Can Do)

The wash-day effect: When you wash your hair less frequently, several days of naturally shed hairs may be released during one shower. Longer hair can also make the amount look larger.

“The most useful question is not simply how many hairs you are losing, but whether your normal shedding pattern has clearly changed.”

01

Physical or emotional stress

A significant physical or emotional stressor can disrupt the normal hair cycle. More follicles may enter the resting phase, with increased shedding becoming noticeable several weeks or months after the triggering event.

Possible triggers include illness, surgery, high fever, rapid weight loss, emotional stress or a prolonged period of exhaustion.

02

Postpartum hormonal changes

During pregnancy, hormonal changes can keep more hairs in the active growth phase. After birth, hormone levels change again and many of those retained hairs may begin shedding within a similar period.

This can cause a noticeable increase in shower shedding and thinning around the temples. Although postpartum shedding is often temporary, seek professional advice when it feels severe or does not begin settling.

03

Perimenopause and menopause

Hormonal changes during perimenopause and menopause can affect hair density, texture and the length of the growth phase. Some women notice that their hair becomes finer, their part widens or their ponytail gradually feels smaller.

Thyroid changes, stress and nutrient deficiencies can also contribute during this stage of life, so ongoing thinning is worth discussing with a healthcare professional.

04

Female or male pattern hair loss

Pattern hair loss usually develops gradually. In women, it may appear as a widening part or reduced density through the crown. In men, it commonly affects the temples, hairline or crown. Early professional assessment can help identify suitable treatment options.

05

Nutritional deficiencies or restrictive dieting

Hair growth can be affected when the body is not receiving enough energy, protein or essential nutrients. Low iron stores and other deficiencies may contribute to increased shedding in some people.

Avoid guessing with high-dose supplements. A healthcare professional can advise whether blood tests or dietary changes may be appropriate.

06

Illness, medication or thyroid changes

Certain health conditions, hormonal changes and medications can influence the hair cycle. Shedding may also occur following a significant illness, high fever or major medical treatment.

Never stop prescribed medication because of hair loss without first speaking with the clinician who prescribed it.

07

Scalp irritation, flaking or inflammation

An itchy, inflamed or heavily congested scalp can increase scratching, discomfort, breakage and visible shedding.

Use gentle cleansing products and avoid anything that causes burning or persistent irritation. Redness, thick scale, sores or scalp pain should be assessed professionally.

08

Tight hairstyles and repeated tension

Regularly wearing tight ponytails, extensions, braids or buns can place repeated tension on the hair and follicles, especially around the hairline. Alternate your styles and avoid pulling the hair tightly in the same position every day.

09

Hair breakage mistaken for shedding

Not every strand in the shower has fallen from the root. Bleaching, frequent heat styling, rough brushing and chemical processing can cause hair to snap along the shaft.

Naturally shed hairs are often full-length strands. Broken hairs are usually shorter and may vary considerably in length.

A consistent scalp ritual

Support the environment your hair grows from

Scalp care cannot correct every cause of hair loss, but a gentle and consistent routine can help keep the scalp feeling refreshed, comfortable and balanced.

Tui & Moon’s Rosemary & Caffeine Scalp Spray is a lightweight leave-on botanical formula designed for direct daily application without leaving the roots feeling oily.

Wash gently

Use your fingertips rather than your nails, avoid aggressive scrubbing and detangle your hair carefully.

Do not avoid washing your hair from fear

Washing generally releases hairs that had already entered the shedding stage. Leaving the scalp unwashed will not reattach them.

Reduce tension, heat and chemical damage

Choose looser hairstyles and reduce very hot tools or repeated chemical processing when breakage is contributing to visible hair loss.

Eat a balanced and adequate diet

Include sufficient protein and a varied range of foods. Seek professional advice before starting high-dose hair supplements.

Track changes monthly rather than daily

Photograph your part, temples and hairline in similar lighting once a month. This gives you a more useful comparison than checking anxiously every day.
