Hair Intelligence — Hair Loss
Why is my hair
falling out?
You noticed it on your pillow. Then in the shower drain. Then on your hands after running them through your hair. If you're asking yourself this question, you're not alone — and you're not imagining it.
Hair loss is one of the most Googled health concerns in the world, and yet most of the answers you'll find are either too clinical or too vague to actually help you understand what's happening to your hair specifically. So let's have a real conversation about it.
First, something that might calm you down a little: losing between 50 and 100 hairs a day is completely normal. Your hair goes through constant cycles of growth, rest, and shedding. The problem starts when the shedding outpaces the growth — when you're losing hair faster than your scalp can replace it.
"Hair loss is rarely random. Most of the time, it's your body trying to tell you something — and once you understand what, the path forward becomes much clearer."
The most common reasons your hair is falling out
01
Stress — and not just the obvious kind
You already know that stress is bad for you. But what most people don't realize is that hair loss from stress is delayed — it usually shows up 2 to 3 months after a stressful event. So if your hair is falling out now, think back to what was happening in your life a few months ago. A breakup, a job change, moving countries, a period of insomnia. Your scalp keeps score even when you think you've moved on.
02
Hormonal changes
Pregnancy, postpartum, stopping birth control, perimenopause — any significant hormonal shift can trigger what's called telogen effluvium, where a large number of hairs enter the shedding phase at once. If you're postpartum and watching your hair fall out in clumps, know that this is one of the most common and temporary forms of hair loss. Your body is recalibrating. It takes time, but it usually stabilizes.
03
Nutritional deficiencies
Your hair needs iron, zinc, biotin, vitamin D, and protein to grow. When you're deficient — especially in iron or vitamin D — your body deprioritizes hair growth and redirects resources to more vital functions. This is particularly common in women who eat restrictively, have heavy periods, or follow plant-based diets without careful supplementation. The frustrating part is that the deficiency can be subtle enough to not show up in how you feel day-to-day, but your hair notices.
04
Scalp health — the one nobody talks about
A congested, inflamed, or imbalanced scalp is one of the most underdiagnosed causes of hair loss. Product buildup, hard water mineral deposits, dandruff, and scalp inflammation can all compromise the follicle environment and slow or stop hair growth. If your scalp is itchy, flaky, or constantly oily no matter what you do, that's not a cosmetic problem — it's a hair loss risk factor. A healthy scalp is the foundation of healthy hair growth.
05
Mechanical damage from how you wear your hair
Tight ponytails, braids, and extensions worn repeatedly in the same position cause traction alopecia — hair loss along the hairline and temples from the constant pulling. This type of hair loss is entirely preventable, but if it's been going on for years, the follicle damage can become permanent. If your hairline has been receding and you wear your hair up every day, the connection is worth investigating.
06
Genetics
Female pattern hair loss — a gradual thinning at the crown and widening of the part — affects more than one in three women at some point in their lives. It's driven by sensitivity to androgens (male hormones that all women have in small amounts) and tends to become more noticeable after menopause. If you have a mother or grandmother who experienced significant thinning, your risk is higher. But genetic predisposition is not destiny — there's a lot that can be done to slow progression and support the follicles you have.
What you can actually do about it
The most important thing you can do is stop guessing and start understanding your specific situation. Hair loss is not one condition with one solution — it's a symptom with many possible causes. Using the same shampoo your friend swears by, or adding biotin because you saw it on TikTok, is unlikely to work if those aren't addressing your actual root cause.
Before you invest in products or treatments, it's worth doing a proper assessment of your scalp condition, your hair's current health, and the likely contributing factors in your lifestyle and history. That's exactly what Hebra was built to do.
Hebra analyses photos of your actual hair alongside your personal history — your stress levels, hormone changes, chemical treatments, water quality, and more — and gives you a specific diagnosis, not a generic checklist.
It takes about 10 minutes. And it's free.
