What Causes Hair Loss In Women?

A dermatologist once stated that growth cycles should be focused on when it comes to hair growth. Once the cycle gets awry, hair loss often occurs.

Most women notice hair fall problems happening to them once they enter their fifties. Unfortunately, though, it can happen to anyone at any age.

Losing 50 to 100 strands of hair each day is quite normal. Hair washing increases it to up to 250 a day.

While men seem to recede at the hairline, women experience thinning hair on the top third up to the bottom part of the hair.

  • Genetics can be a factor. Take a look at your mom, aunts, or grandmom.
  • Medical conditions like anemia, thyroid disorders, or hormone disorders like PCOS are likely culprits.
  • Pregnant women experience hair loss.
  • Menopause can also lead to thinning of hair.
  • Stress, dramatic weight loss, and even physical trauma can impact the growth and thickness of the hair.

A commonly asked question is “Does Smoking Contribute To Hair Loss?”. To answer this, a study was conducted that directly correlates smoking to male pattern baldness.

The factors that make smoking cause hair fall are plenty. Cigarette smoking is, after all, known for its health risks.
