Purple shampoo has become a popular hair care product for those with blonde, silver, or gray hair. It helps neutralize brassy and yellow tones, leaving the hair looking brighter and more vibrant. However, concerns have been raised about whether purple shampoo can cause hair loss. In this article, we'll explore the potential risks associated with purple shampoo and discuss how to use it safely to avoid hair loss.

Can Purple Shampoo Cause Hair Loss?

There is no scientific evidence or study that directly links purple shampoo to hair loss (source). However, overusing purple shampoo can cause dryness, leading to brittle and fragile hair that becomes prone to breakage (source). While breakage is not the same as hair loss, it can still lead to an overall reduction in hair volume and appearance. It's important to follow the recommended guidelines on the bottle and use purple shampoo no more than once or twice a week (source).

Other Potential Risks of Overusing Purple Shampoo

Overusing purple shampoo can lead to other issues besides hair breakage, including:

  • Buildup on hair shafts, causing hair to become dull and darker (source)
  • Reverse effect, leaving blue or violet nuances on the hair (source)
  • Overly dry and opaque-looking hair (source)

How to Use Purple Shampoo Safely

To avoid the risks associated with overusing purple shampoo and to maintain healthy hair, follow these guidelines:

  • Use purple shampoo only once or twice a week, as recommended on the bottle
  • Leave the shampoo on your hair for the suggested duration before rinsing thoroughly
  • Alternate purple shampoo with a regular, moisturizing shampoo to avoid over-drying your hair
  • Consider using a deep conditioning treatment or hair mask once a week to maintain hair health

By following these recommendations, you can safely use purple shampoo to maintain your desired hair color without causing hair loss or breakage.


Purple shampoo does not directly cause hair loss, but overusing it can lead to dry, brittle hair that is more prone to breakage. To prevent these issues, it's important to follow the manufacturer's guidelines for using the product and to incorporate moisturizing and conditioning treatments into your hair care routine. By using purple shampoo responsibly, you can enjoy the benefits of brighter, more vibrant hair without the risks associated with overuse.
