The Science of Hair Shedding: When Is It Normal and When to Worry

all panel mahadev, mahadev book login, allpanel login:Hair shedding is a common occurrence that most people experience on a daily basis. In fact, it’s normal to shed between 50 to 100 hairs per day. However, when you start noticing an excessive amount of hair falling out, it can be quite concerning and lead to worries about balding or other underlying health issues.

The science behind hair shedding is quite fascinating. Our hair goes through a natural growth cycle that consists of three phases: anagen, catagen, and telogen. The anagen phase is the active growth phase, the catagen phase is a transitional phase, and the telogen phase is the resting phase where the hair eventually falls out and new hair begins to grow in its place.

So when is hair shedding considered normal, and when should you start worrying? Let’s delve deeper into the science of hair shedding to find out.

Understanding Normal Hair Shedding

As mentioned earlier, it’s completely normal to shed between 50 to 100 hairs per day. This is because our hair follicles go through the natural growth cycle mentioned earlier. During the telogen phase, which lasts for about 2 to 4 months, the hair falls out and is replaced by a new hair.

It’s important to note that not all hairs are in the same phase at the same time, which is why we don’t go bald every time we shed hair. The average person has about 100,000 hair follicles on their scalp, and about 80-90% of them are in the anagen phase at any given time.

Factors that can affect normal hair shedding include age, genetics, hormonal changes, and lifestyle. For example, as we age, our hair growth slows down, leading to increased shedding. Hormonal changes, such as pregnancy or menopause, can also cause temporary hair shedding. And poor diet, stress, and certain medications can all contribute to abnormal hair shedding.

When to Worry About Hair Shedding

Excessive hair shedding, also known as telogen effluvium, can be caused by a variety of factors. Some common causes include:

1. Stress: Physical or emotional stress can disrupt the hair growth cycle, leading to increased shedding. This type of hair loss is usually temporary and the hair will regrow once the stress is alleviated.

2. Nutritional deficiencies: A lack of essential nutrients, such as iron, zinc, and vitamin D, can impact hair growth and lead to excessive shedding.

3. Hormonal imbalances: Conditions such as thyroid disorders, polycystic ovary syndrome (PCOS), and hormonal fluctuations can cause hair shedding.

4. Medical conditions: Certain medical conditions, such as alopecia areata, can cause patchy hair loss, while others, such as lupus or diabetes, can lead to overall hair thinning.

5. Medications: Some medications, such as antidepressants, blood thinners, and chemotherapy drugs, can cause hair shedding as a side effect.

If you notice an increase in hair shedding that lasts for more than a few months, it’s best to consult with a healthcare provider or a dermatologist to determine the underlying cause. They may recommend blood tests, scalp examinations, or other diagnostic tests to identify the root cause of the shedding.
