How much hair loss in the shower is normal? What 50 to 100 hairs a day looks like

Reviewed by The Wellness Team. Last reviewed October 2026.

Short answer: losing 50 to 100 hairs a day is normal, according to the NHS. A clump in the shower drain can look alarming, but most of it is hair that had already shed and was waiting to come out. What matters is whether the amount has changed, and whether your hair looks thinner.

Why the shower looks worse than it is

Hair that has finished its growth phase stays in the scalp until something moves it. Washing, brushing and tying your hair all release it. If you wash every three or four days, you collect several days of normal shedding in one go. That is why the drain looks full on wash day even when nothing has changed.

Normal shedding is spread across the scalp and you do not notice thinning. In the hair cycle, about 15% of scalp hairs are resting and ready to shed at any time, according to the British Association of Dermatologists (BAD).

A simple way to check

Do this for two weeks, so one odd day does not mislead you:

• Wash on your usual schedule and keep the routine the same.
• After each wash, collect the hair from the drain and your hands, and count it or photograph it on a white towel.
• Take a photo of your parting and temples under the same light each week.
• Write down any illness, stress, crash diet, new medicine or childbirth in the last six months.

If your count is regularly above about 100 on a wash day with no gap between washes, or you can see more scalp than before, ask for an assessment.

When shedding is a sign of something

Telogen effluvium. This is a sudden rise in shedding. The BAD says the share of resting hairs can rise from 15% to 30% or more, and it often starts around 3 months after a trigger. Common triggers include illness with a fever, major stress, rapid weight loss, childbirth and some medicines. Shedding usually lasts 3 to 6 months and then settles without treatment. It is called chronic if it lasts longer than 6 months, and it can come back if a cause such as iron deficiency is not treated.

Pattern hair loss. This is slower. Hairs get finer, the parting widens or the temples recede. It does not settle by itself. Finasteride and minoxidil are the main treatments the NHS lists for male pattern baldness, and minoxidil for female pattern baldness. They do not work for everyone and only work for as long as they are used. The NHS also says no treatment is 100% effective.

Patchy loss, scalp pain, scarring or broken hairs. These need a proper look at the scalp. See our guide to trichoscopy, which is a magnified scalp check that helps tell the types apart.

The pull test, and why it can mislead

A clinician may gently pull a small bundle of hairs to see how many come out. The BAD notes that this can give a falsely negative result if you washed your hair within 48 hours beforehand. If you are booked for an assessment, ask when to wash.

What to check first

The NHS advises seeing a GP first to find out what is causing hair loss before going to a commercial hair clinic, and we agree. The usual first step is to find out why. Ask your GP or clinic about:

• ferritin (iron stores) and a full blood count
• thyroid function
• vitamin D
• hormone tests if you have irregular periods, acne or excess hair growth

Our guide to blood tests for hair loss explains what each result means.

Where PRP fits

Platelet-rich plasma (PRP) is made from a small sample of your own blood and injected into the scalp. The research on PRP for pattern hair loss is mixed. Trials are small and methods differ, so results vary between people. It is not a treatment for shedding that will settle by itself, so we would not suggest it for a recent telogen effluvium until blood tests and time have had their chance.

If the cause is pattern hair loss, PRP can be one part of a plan alongside other treatments. We are open about the limits, and we do not guarantee regrowth.

Our prices are plain: PRP for hair is £450 per session, or £1,215 for a course of three.

When to be seen sooner

• Hair is coming out in patches, or you have bald areas.
• Your scalp is painful, red, flaky or scarred.
• You have lost a lot of hair within a few weeks.
• You are also very tired, have lost weight without trying or have heavy periods.

Next step

If your hair looks thinner, not just messier in the drain, we can take a magnified look at your scalp, talk through your history and tell you honestly whether PRP suits you.
