Here are some causes of hair loss that are not that well known, but can result in obvious hair thinning:
Stress is a major cause of hair loss. When you experience physical or mental, it causes your hair follicles react by going into resting phase from the growing phase. When this occurs, your hair will fall out.
2. Air Pollution
Air pollution is a major problem in India. Besides respiratory disorders, air pollution can also lead to hair loss. The contaminants, like dust, smoke and chemicals, in the air cause hair follicles to die, resulting in hair loss.
You may eat healthy and look after your hair well. However, if you suffer from conditions, like thyroid disease, or have unhealthy eating habits, it can result in nutritional deficiencies, causing your hair to fall out. Even fad diets or diets that are extremely restrictive can lead to malnutrition and consequently leading to hair falling out in clumps.
4. Changes in the Season
Changes in the season can have an adverse effect on your hair. Usually, just before winter sets in, you may notice an increase in hair loss. So, if you find that in October and November you are experiencing sudden hair loss, blame it on the weather. You have nothing to worry about, as this hair loss is reversible and new hair will start growing in winter.
5. Hormonal Changes
Hormonal changes are one of the main reasons for hair loss in women. Usually, women experience increased hair loss after childbirth or even when they are entering menopause. However, men are not spared either. Increase in a sex steroid and androgen hormone called dihydrotestosterone (DHT) is one of the common reasons for hair loss in men. In fact, this hormone is present in women, as well, and if it increases, it can cause hair growth in unwanted areas while causing excessive hair loss from the scalp.
6. Blocked Hair Follicles
Hair follicles can sometimes get blocked due to excessive buildup of oil on the scalp. Blocked hair follicles cannot breathe and this makes them weak. And, a weak hair follicle means hair loss. Usually, oil buildup on the scalp occurs if you do not maintain optimal hygiene or use cheap hair care products on your hair and scalp.
These are some of the reasons for sudden hair loss. If you find that you are losing a lot of hair loss, it is time to consult an expert and ascertain the root cause of hair thinning so that you can take remedial measures promptly.
