Can Hard Water Cause Hair Loss?

Hard water is not the primary cause of hair loss. Experts in the field have stated that while hard water can dry out and damage hair if not hydrated properly, there's no truth behind the claim that it directly causes hair loss. A study comparing the effects of hard water and distilled water on hair found no statistical difference in tensile strength and elasticity, indicating that hard water does not interfere with the physical properties of hair that might lead to hair loss.

However, it is noted that people with eczema or psoriasis may experience more excessive hair loss when exposed to hard water for prolonged periods. Additionally, the misconception persists that hard water leads to hair loss, primarily due to associated factors like brittle hair and breakage.

To summarize, while hard water may lead to other hair-related concerns like dryness and frizziness, hair loss itself is not widely attributed to hard water exposure alone.
