These problems may be caused by something that many overlook: hard water.

This shampoo and conditioner duo is tailored specifically to combat hard water problems directly, keeping your hair healthy, soft, and shiny. In this article, we’re going to take a look at all you need to know about hard water, how it affects your hair, and why PROINSCARE Deep Repair Series is the best hard water shampoo according to professionals and hair care specialists alike.
Ready to know how to prevent hard water damage to hair? Let’s begin by knowing what hard water is.
Hard Water
What is Hard Water?
You might be wondering, what is hard water? Hard water is just water that contains a high concentration of dissolved minerals, mostly calcium (Ca²⁺) and magnesium (Mg²⁺). They are safe to drink, but not desirable in your hair and skin.
Did you ever realize that soap or shampoo will not lather or leave a residue? That is a definite indication that you have hard water. Individuals residing in regions with hard water experience dry skin and hair that becomes hard or rough when washed. Another indication of hard water is that white, chalky scale forms in kettles or pipes.
Water hardness is expressed as parts per million (ppm) of calcium carbonate (CaCO₃). Below is a quick reference chart for water hardness levels:
| Soft Water | 0 – 60 ppm |
| Moderately Hard Water | 61 – 120 ppm |
| Hard Water | 121 – 180 ppm |
| Hardness Classification | ppm (CaCO₃) |
| Very Hard Water | More than 180 ppm |
If water hardness in your area is more than 120 ppm, you are likely to be using hard water.
How Does Hard Water Affect Hair?
Shampooing hair with soft water and hard water is a big difference. Hair shampooed with soft water is soft, smooth, elastic, shining, and comb-friendly. But hair shampooed with hard water becomes primarily dry, rough, stiff, dull, knotted, and comb-resistant. Why?
Hard water minerals stick to your scalp and hair roots and deposit a residue layer that makes your hair heavy and unmanageable. It also dries out your hair by stripping it of natural oils, causing frizz and splitting. Hard water hair care is thus so distinct from regular hair care.
Global Hard Water Regions – Where Does This Problem Occur?
Hard water is not only an issue in some areas—it’s widespread throughout the world. If you reside in one of these worldwide hard water areas, you may be experiencing the consequences of hard water on a daily basis:
- Southeast England, being in Europe, has a range between 120 to 180+ ppm water hardness and is very hard to hard water.
- Areas in the Midwestern United States, like Texas and Arizona, have a tendency of water hardness above 120 ppm.
- Bangalore, India, has very hard water in almost 24% of its locations with more than 200 ppm hardness levels.
- And in Vietnam, also possesses a mix of water hardness by region. For example:
| Region | Water Source | Hardness (ppm) | Classification |
| Hanoi Groundwater | Groundwater | 155 | Hard Water |
| Saigon River | Surface Water | 175 | Hard Water |
| Phu Tho Province | Groundwater | 100 | Moderately Hard Water |
| Ha Long Bay, Quang Ninh | Groundwater | 25 | Soft Water |
| District 10, Ho Chi Minh City | Groundwater | 28 | Soft Water |
This implies that most consumers and salons experience hard water on a daily basis, and it is thus essential that they use the best hard water hair product in their hair care regimen.
If hard water causes such hard hair problems, why can’t we just use any shampoo to fix the problem? Let’s find out why regular shampoo and conditioner products aren’t quite up to the task.
Why Won’t Regular Shampoo and Conditioner Work on Hard Water?
Most shampoos are designed to wash dirt and grease out of hair. But for the effect hard water has on hair, regular shampoos simply will not do. Why? Because hard water deposits minerals such as calcium and magnesium scale, regular shampoos will not be able to wash those away. Actually, some shampoos will make the hair feel even drier because the shampoos remove natural oils but fail to remove the mineral deposits.
And why would a shampoo be suitable for hard water? It needs to be specially developed with products that can cope with the task of hard water. Such shampoos and conditioners need to have:
- Chelating compounds like citric acid chelate calcium and magnesium ions to dissolve and eliminate mineral deposits.
- Hard water stable surfactants like sodium lauroyl sarcosinate, which function even in mineral water and clean hair without leaving a residue.
- Hair reconstruction agents such as hydrolyzed keratin, which reconstruct broken areas on hair filaments and reinforce hair internally.
- Humidity-sealing ingredients like ceramides, which seal the hair cuticle, reduce frizz, and keep hair from getting dry and rough.
When combined, they reverse the effects of hard water damage and render hair healthy and manageable.
Since not every shampoo has these properties, most people who live in hard water regions need to find the most suitable shampoo for hard water to keep their hair in the best state they can possibly achieve. This is where the expert guidance of LocRoyal enters the picture—the PROINSCARE Deep Repair Shampoo and Conditioner.
