Does Keratin Cause Hair Loss?

Keratin itself does not cause hair loss. In fact, keratin is a protein that is a fundamental component of hair and is responsible for its structure, strength, and resilience. It forms the primary building block of hair, nails, and the outer layer of the skin.

Hair loss can result from various factors, and while keratin is not the cause of hair loss, certain hair treatments involving keratin, such as keratin straightening or smoothing treatments, have been a subject of controversy and concern regarding their potential impact on hair health.

Keratin treatments that use formaldehyde or other harsh chemicals to bind keratin to the hair may cause damage and breakage over time, leading to the appearance of thinning hair. This damage can occur when the treatments are applied too frequently or if the hair is not properly cared for afterward.

Other common causes of hair loss include:

  • Genetics: The most common cause of hair loss is hereditary male or female pattern baldness.
  • Hormonal changes: Hormonal imbalances, such as those occurring during pregnancy, menopause, or thyroid disorders, can lead to hair loss.
  • Medical conditions: Certain medical conditions like alopecia areata, scalp infections, and autoimmune diseases can result in hair loss.
  • Stress and diet: Extreme stress, crash diets, and nutritional deficiencies can also contribute to hair loss.
  • Hairstyling practices: Overuse of heat styling tools, tight hairstyles (like braids or ponytails), and harsh chemicals in hair products can damage hair and lead to hair loss.

If you’re experiencing hair loss, it’s essential to identify the underlying cause. Consulting with a dermatologist or a healthcare professional with expertise in hair health can help diagnose the reason for your hair loss and provide appropriate treatment recommendations.
