5 Best Shampoos for Thinning Hair and Why They Work

shampoo for thinning hair
  • Hair loss affects both men and women.
  • It is usually caused by genetic factors.
  • Anti-thinning shampoos promote hair growth and can help you attain a fuller head of hair.

For the vast majority of people, hair loss is hereditary and a natural part of the aging process, but the good news is there are a number of options to help you attain fuller, more luscious hair.

The first line of defense lies in topical growth treatments. There are a number of over-the-counter thickening shampoos available that are specifically designed to prevent hair loss and stimulate new hair through the use of amino acids, antioxidants and other compounds that help hair thrive.

Causes of Thinning Hair

The average person loses between 50-100 hairs every single day, according to the American Academy of Dermatology. You probably don’t notice this shedding on a day-to-day basis because new hairs typically grow to replace the ones you’ve lost.

Hair loss occurs when new hairs stop growing. As many as 42% of men aged 18-49 suffer moderate to extensive hair loss, according to figures published in Dermatologic Surgery. While hair loss is most commonly associated with men, studies show that 40% of women are affected by female pattern hair loss by the age of 50.

What causes hair thinning in men?

  • Genetics: Hair loss is most commonly caused by genetic factors, as well as hormone levels and the natural aging process. If male pattern baldness runs in your family, there’s a good chance that you too will experience hair loss.
  • Medical conditions: There are a range of health issues and medical conditions that cause hair loss in men, such as psoriasis, ringworm and areata. There are also many prescription medications that can cause hair loss as a side effect. These include drugs used for cancer, arthritis, depression and more.
  • Stress: You might experience hair loss if you go through a traumatic event. Hair loss usually begins about three months after the event. In this scenario, hair loss is usually temporary and your hair will start to regrow a few months later.
  • Hairstyle: Certain hairstyles like pigtails and cornrows can pull your hair with significant force, and over time this traction can pull out individual strands of hair and even damage the follicles.

What causes hair thinning in women?

Hair loss in women is often caused by the same factors that affect men. However, female thinning hair can also be caused by:

  • Pregnancy: The dramatic hormone fluctuations during pregnancy can affect the life cycle of your hair, resulting in more hair loss than usual. This condition, known as telogen effluvium, typically resolves itself in approximately six months.
  • Menopause: During menopause, your body produces lower levels of estrogen and progesterone, two hormones that play a key role in your hair’s natural life cycle. Your body also starts to produce more androgens, which are a group of male hormones. Combined, these factors can lead to hair loss.
  • Health conditions: Health conditions that are unique or more common among women such as anemia, thyroid disease and polycystic ovary syndrome can lead to thinning hair.
  • Excessive hairstyling: Blow dryers, flat irons, and hair dye can put a significant amount of stress on your hair and potentially affect your hair’s growth cycle.
