I mainly discuss about the reason behind hair fall.There are many reason for increasing hair fall.

1. 1. Nutritional deficiencies
It might be possible that essential nutrients could also be
missing from your diets like iron, copper, zinc and proteins.
Deficiency of vitamin D is another explanation for hair loss. so as
to avoid this, confirm to urge out and take in some sun.

3.  2. Hormonal Imbalance
 After the age of 30, women can experience hormonal imbalance which
may cause hair loss. this is often usually caused by excessive
dihydrotestosterone (DHT) conversion. albeit estrogen is that the main
hormone that ladies produce, testosterone and other androgens like
DHEA also occur within the human body . As women reach a particular
age, they'll begin to convert these androgens to DHT.

4.  3. Thyroid issues
 if you are doing have a thyroid issue, you'll notice other
symptoms along side hair loss like weight gain or loss,
sensitivity to cold or heat, and changes in heart-rate.

5.  4. Polycystic ovary syndrome (PCOS)
 Women with polycystic ovary syndrome (PCOS) have a hormonal
imbalance which creates higher levels of androgens than normal. This
often causes hair to grow on the face and body, while the hair on the
top grows thinner. PCOS also can cause ovulation problems, acne, and
weight gain.
