Study || Hard Water Impact On Hair

Hard water metals concentrate primarily in the cuticle layer.  A study published in 2011 indicated that these metals can affect certain hair properties, which include:

- stiffening of hair strand
- reduction of combing forces
- improvement of ability to hold a style in virgin hair
- reduction of ability to hold a style in bleached hair

Additionally, certain variables affect the uptake of hard water metals by the hair, such as the:

- condition of the hair (e.g., chemically damaged)
- pH of the water
- level of water hardness
