Lahore, tested live. 🔬💧
Across 8 societies, our TDS readings ranged from 450–700 ppm — anything above 300 ppm is considered unsafe, which means Lahore's tap water is hard, and it's silently working against your hair.
Here's what hard water does to your scalp and strands:
→ Calcium and magnesium bind with your shampoo, leaving a mineral film on the hair shaft
→ That film blocks moisture, roughens the cuticle, and leads to dryness, frizz, and breakage
→ Mineral buildup clogs follicles, causing itching, flaking, and slower hair growth
→ It also strips color and weakens chemically treated hair faster than normal
We didn't stop at TDS. We also tested pH — and most areas came back alkaline. Alkaline water raises the hair cuticle, making it more porous, more prone to frizz, and more likely to lose moisture and color over time. Your scalp's natural pH sits around 4.5–5.5 (mildly acidic) — anything consistently more alkaline pushes it out of balance.
This is exactly why Cross Herb exists. We showed it live: when Cross Herb shampoo meets hard, alkaline water, it still brings the scalp back toward its ideal pH range — protecting the barrier that keeps hair strong, hydrated, and healthy, instead of fighting against what your tap water is doing to it.
Real science. Real results.
