Hair loss can feel overwhelming, whether you are noticing thinning at the crown, a widening part, or more shedding in the shower. Understanding the causes of hair loss can help you take control of the situation and get the right treatment. You’re not alone. Millions of men and women experience hair thinning every year, and the reasons for hair loss can vary widely from person to person.
In this guide, we break down the most common reasons of hair loss, explain why hair falls out, and share the solutions that can help restore your hair and confidence.
Hair loss can be gradual or sudden. It may be temporary or progressive. While every situation is unique, the following are the most common, medically recognized causes of hair loss.
Genetics are one of the most common reasons for hair loss, and this type is known as androgenetic alopecia. It includes both male pattern baldness and female pattern hair loss. It depends on your genes how sensitive your hair follicles are to DHT (dihydrotestosterone), a hormone that gradually weakens the follicles and shortens the growth cycle. As a result, the hair becomes thinner and finer over time, leading to a receding hairline in men and a widening part in women. Without treatment, genetic hair loss typically continues to progress.
Hormonal fluctuations are another main cause of hair loss, and even small shifts can disrupt the normal hair growth cycle. Conditions such as thyroid disorders, pregnancy and postpartum changes, menopause, adjustments in birth control, and PCOS often trigger noticeable shedding. Since hormones influence every cell in the body, even mild imbalances can interfere with hair growth and lead to unexpected thinning or increased hair fall.
One of the most common but unnoticed reasons for thinning hair is high levels of stress. This can cause a great amount of hair follicles to shift to the resting phase prematurely and fall off quickly. Examples of such situations include after a serious illness, surgery, heavy emotional pressure, a lot of rapid weight loss, or great changes in life. Usually, hair loss caused by stress is short-term with proper rest, care, and support, people start regrowing it in months.
It requires a continuous nutrient-based diet to grow strong and healthy. One of the earliest signals of nutritional imbalance is increased hair shedding. Deficiencies in iron, vitamin D, biotin, B12, zinc, or even not taking enough protein can make the hair weak, which disrupts the normal growth cycle of hair. A simple blood test can help diagnose whether these nutritional gaps are leading to hair thinning or more hair fall than usual, thus enabling the selection of corrective treatment and overall improvement of hair.
These underlying health conditions can disrupt the normal hair growth cycle and sometimes cause direct damage to the follicles. The medical conditions most often linked to hair loss include autoimmune diseases like alopecia areata and lupus, scalp infections, diabetes, and anemia. In such cases, treatment of the root cause becomes necessary before hair restoration treatment can be undertaken, as control of such medical conditions often helps in the improvement of hair health and minimizes further shedding.
Certain medications can contribute to hair shedding, and for many people, this becomes an unexpected reason for hair loss. Drugs such as blood pressure medications, antidepressants, blood thinners, specific acne treatments, and chemotherapy can disrupt the hair growth cycle and lead to visible thinning. In many cases, hair begins to recover once the medication is adjusted or discontinued under a doctor’s guidance, making early evaluation important.
Certain hairstyling habits can play a significant role in hair loss, particularly when they place ongoing tension or stress on the follicles. Hairstyles that create tight braids, ponytails, or extensions, along with chemical relaxers, frequent bleaching or coloring, and excessive heat styling, can weaken the hair over time. While early traction alopecia can often be reversed by changing styling practices, prolonged tension may cause permanent follicle damage, making early intervention crucial.
With age, hair naturally becomes thinner and grows more slowly. While aging is a normal cause of hair loss, many people experience more advanced thinning due to reduced follicle activity.

Yes. Pollution, UV exposure, hard water, and toxins can make the hair strand more fragile and cause irritation on the scalp, leading to increased shedding or breakage over time.
Scalp issues like dandruff, seborrheic dermatitis, and psoriasis can irritate the follicles. While they don’t usually cause permanent hair loss, inflammation can increase shedding and make hair look thinner until treated.
Over-brushing can lead to breakage, but it doesn’t cause actual follicle loss. Brushing gently and using the right tools can prevent unnecessary damage
