Most people first notice hair loss in the shower drain or on a pillow, and the first reaction is to start counting. Counting doesn’t tell you much. Everyone sheds, usually somewhere around 50 to 100 hairs a day, and a clump in the brush always looks worse than it is. The signs that matter are shedding that goes on for weeks, a part that keeps getting wider, or a hairline that is moving back.

Finding the cause matters more than anything else, because different causes need different handling.

Common causes#

Pattern hair loss. This is the most common cause by a wide margin. It runs in families. Your follicles respond to the hormone DHT by shrinking a little with each growth cycle, until the hairs come in thin and short and eventually stop coming. In men it usually starts at the temples and crown. In women it tends to show up as a wider part and thinner hair on top, while the hairline mostly stays where it was. It’s slow, and you can lose a lot before anyone else notices.

Shedding after a shock. Surgery, a high fever, a bad illness, childbirth, crash dieting, a stretch of heavy stress: any of these can push a lot of hairs into the resting phase at once. They fall out about two to three months later, which is why people rarely connect the two. You have the flu in August, your hair comes out in November, and you blame the shampoo. This type (telogen effluvium) usually grows back after the trigger is gone, but it takes months.

Nutrition and thyroid. Low iron is a frequent culprit, especially in women who menstruate. Low vitamin D, too little protein, and long stretches of very low calories show up as well. Thyroid problems, overactive or underactive, can thin hair over the whole scalp. All of these are fixable, but you have to know which one you have, and guessing with supplements is a poor way to find out. Some supplements cause shedding when overdone, vitamin A being the usual example.

Pulling. Tight ponytails, braids, weaves, and extensions keep tension on the follicle. Do that for years and the loss can become permanent. It’s one of the more preventable kinds and one of the most ignored.

Medications and medical conditions. Certain blood pressure drugs, antidepressants, blood thinners, and chemotherapy can cause shedding. Alopecia areata, an autoimmune condition, produces smooth, round bald patches, sometimes quickly. Scalp infections and scarring conditions can destroy follicles outright. If you suspect a prescription is involved, talk to whoever prescribed it before changing anything.

What you can actually prevent#

Pattern hair loss can’t be prevented with lifestyle. Genetics decides most of it. What you can do is catch it early, because the treatments work by holding on to follicles you still have, not by reviving ones that are gone. Minoxidil (over the counter) and finasteride (prescription, and not suitable for everyone) have the best evidence behind them. Both take months to show anything, and the benefit fades if you stop. A dermatologist can tell you which one fits.

For nearly everything else, the list is short and unglamorous:

  • Give your scalp a break from tension. Rotate hairstyles, loosen what you can, and don’t sleep in tight braids.

  • Eat enough, and enough protein. Skip the crash diets. If you suspect a deficiency, ask for bloodwork (ferritin, vitamin D, thyroid) before you buy anything.

  • Go easy on bleach, relaxers, and hot tools. These mostly cause breakage along the shaft, not loss at the root, but breakage makes thin hair look thinner.

  • Treat scalp problems. Persistent dandruff or an itchy, flaking scalp is worth dealing with early.

  • Quit smoking. It’s linked with earlier thinning, and you have plenty of other reasons.

  • Take sleep and stress seriously. You can’t remove them, but they are triggers for the shedding described above.

Most of the oils, gummies, and serums marketed for hair growth have little solid evidence behind them. Some are harmless, and many are expensive.

When to see a doctor#

Go sooner rather than later if the loss is sudden or patchy, if your scalp is red, painful, or scaling, or if the hair loss comes with fatigue, weight changes, or irregular periods. Some scarring conditions destroy follicles for good, and the window for treating them is short.

If you only suspect something is changing, photograph your part and hairline in the same light, once a month. It’s the cheapest way to find out whether you’re imagining it.
