7 Tell-Tale Signs That Your Hair Is Battling Hard Water

Is your hair feeling lackluster? It may be a sign that hard water is to blame. Hard water has been saturated with minerals like calcium and magnesium—and these can leave you with dry, brittle strands.

If you’re noticing seven telltale signs of dullness in your locks, it could mean that the mineral-ridden waters are taking their toll on your mane. Knowing how to recognize them might save those precious tresses from further damage.

Read my comprehensive article about what hard water is.

1. Dull Appearance

Hard water can strip the natural oils from your hair, leaving it dull and lifeless. The minerals in your hard water are left behind as a thin deposit of solids.

This scale has a flat, non-shiny surface which makes you hair seem dull.

If you’ve been noticing a lack of shine and vibrance in your hair, it might be due to hard water.

2. Hair Damage

The minerals in hard water can build up on your hair, resulting in dryness and damage. Over time, this can cause breakage and split ends, which can leave your hair looking frizzy and unkempt.

The calcium and magnesium minerals form a scale that acts like tiny knives, cutting and damaging your hair. Repeated washing and rinsing with hard water will give you split ends that are difficult to repair.

3. Limp, lifeless hair

The minerals in hard water can leave your hair limp and lifeless. The minerals in hard water are left behind as a coating on your hair when the water evaporates. This scale can weigh down your hair, making it look limp.

It also makes your hair stiff, so it won’t flow and move naturally.

If your hair looks dull and lacks volume, hard water could be the culprit.

4. Dry hair

Hard water can be especially tough on your hair, robbing it of its natural oils and making it difficult to retain moisture. This leaves your locks dry, brittle and weak.

Fortunately, there are solutions out there that will get those tresses back in tip-top shape.

5. Itchy Scalp

Fed up with an itchy, uncomfortable scalp? Hard water could be the source of your irritation. The minerals in hard water can accumulate over time and clog hair follicles leading to inflammation.

To ward off this pesky problem, use a shampoo and conditioner specifically designed for harder waters.

6. Color Fading

Hard water may be the cause of your hair color fading faster than you’d like. The minerals can break down the dye molecules, robbing you of vibrant locks.

A simple solution? Invest in a water softener system – that way, your beautiful new hue will stay with you for longer.

7. Thinner Hair

Finally, hard water can cause your hair to become thinner over time. The minerals in hard water can cause a build up on your hair, which can leave it feeling heavy and weighed down. Regular use of a clarifying shampoo can help to remove the minerals from your hair and restore its natural body and bounce.
