A New Investigation Claims Keratin Shampoo Causes Hair Loss

Keratin Shampoo Causes Hair Loss and Inflammation? 

A recent Keratin Shampoo class action lawsuit investigation alleges that keratin shampoo causes hair loss and scalp irritation due to concerning ingredients.

Formaldehyde, which is a known carcinogen, have been identified as causative to scalp irritation and hair loss and has been reportedly released in traces from DMDM Hydantoin, a preservative found in some keratin shampoos.

Keratin shampoos affected by this lawsuit investigation include:

  • TRESemmé Keratin Smooth
  • OGX Ever Straightening Plus Brazillian Keratin Therapy Shampoo
  • Keratin Complex Smoothing Therapy Keratin Color Care Shampoo
  • It’s A 10 Miracle Shampoo Plus Keratin

…and more.

Keratin Shampoo and Hair Loss: What to Know

Keratin is the primary protein found in hair, nails, and skin and has been a popular hair care ingredient as it reportedly makes the hair stronger, softer, smoother, and has more shine. This was backed by scientific research.

However, another study found that these issues may have been caused by DMDM Hydantoin. The Environmental Working Group’s Skin-Deep database rates DMDM Hydantoin as a 6 out of 10 with a high allergy and immunotoxicity warning.

Formaldehyde is also believed to cause scalp irritation which can lead to inflammation, resulting in hair loss.
