Water hardness / Baton Rouge
Is Baton Rouge water hard? No.
No. Baton Rouge tap water measures 0 to 52 mg/L of hardness as calcium carbonate, which is soft on the USGS scale. It is the range Baton Rouge Water Company publishes in its Baton Rouge Water Company, 2025 Water Quality Report, which gives no average.

What it means for curly hair
Soft water leaves little mineral residue, so water is unlikely to be the reason your curls feel dull or stiff. Look first at product buildup, porosity and the weather.
Hard water is a plausible factor, not a proven cause of breakage. Sudden shedding, itching, flaking or scalp pain needs a dermatologist, not a chelating routine.
Change less. Learn more.
What to try
No chelating routine is needed for the water. A regular clarifying wash handles product buildup.
What to avoid
Do not clarify or chelate every wash: it strips more than minerals.
Do not blame the water for sudden shedding, itching, flaking or scalp pain. That is a reason to see a dermatologist.
Every number keeps its source.
