Hard Water vs Soft Water Hair Care: Which is Better? 

Hair wash is an essential part of the hair care routine and a head bath is vital for healthy and shiny hair. But you might have sometimes noticed a dry, brittle texture right after walking out of the shower. If you wonder what the reason is, it could be water. If you are not already aware, there is a huge difference in hard water vs soft water hair health.

The amount of salts like calcium carbonate, and magnesium sulfate in water determines the quality of the water. About 85% of the population in the US lives in hard water territory, while only 15% of the US population gets soft water.

Hard water contains a high concentration of minerals, like calcium and magnesium, which can cause dry and brittle hair. On the other hand, soft water has a low mineral concentration and is much healthier for hair. 

Continue reading the article to compare the effects of hard water vs soft water hair wash effects.

What effects does hard water have on hair

Water naturally becomes hard when it picks up rock minerals while running through rivers, streams, and wells. Hard water contains excessive concentrations of minerals such as calcium and magnesium. It is entirely safe for drinking, showering, cooking, and other uses. But it is not a great choice for the skin and hair.

A research study has found that hard water does not interfere with hair elasticity or tensile strength. But, the hardness of water prevents the lathering of soap or shampoos. It restricts the components in the formulas and the dirt you’re attempting to remove from completely dissolving.

This sometimes causes washing with hard water to leave behind a film-like residue or buildup called scum. The residue on the skin can aggravate breakouts and dryness and even irritate those with sensitive skin. On top of that, hard water can contribute to rapid fading and changing color in color-treated hair.

It may be tough to tell if your water is soft or hard, and it may also be difficult to detect whether damage to your hair is caused by water quality or other factors. These are three indicators of hard water on hair to help you tell the difference.

Dry or brittle hair

Hair washed in hard water can be extremely dry and brittle, as the hard water prevents moisture from entering the hair. So, your hair may appear dull and lifeless. Such hair is more prone to damage and breakage.

Hair damage and breakage

Hard water can cause hair strands and follicles to weaken over time, even decreasing hair thickness. This makes the hair more vulnerable to damage and breaking. Even basic hair care, such as daily brushing and hairstyling (such as tight ponytails), may intensify the damage caused by hard water.

Hair Loss

Hair loss is a less frequent symptom of hard water. In severe circumstances, hard water can badly damage your scalp and cause hair loss. Those with Eczema, Dermatitis, Psoriasis, or other skin conditions are more likely to suffer from hard water damage, such as skin irritation, excessive dryness, and hair loss.

What does soft water do to your hair

Soft water is surface water with relatively low ion concentrations, particularly calcium and magnesium ions. It occurs naturally when hard, impenetrable, and calcium-deficient rocks are responsible for developing runoff and river drainage basins.

Soft water moisturizes hair and makes it smooth, soft, and manageable. However, if your hair is too fine, it might become limp due to soft water. You can rectify this by using a voluminous shampoo and conditioner.

How can you protect your hair from harsh water damage

Damage caused by hard water is not permanent. It can be easily reversed or prevented with the following steps:

• Install a water softener or use distilled water to wash hair
• Use clarifying shampoos and conditioners to wash your hair
• Apply treatments or masks on your hair often
• Massage your scalp while you wash
• Apply citrus and vinegar rinse
• In case of hair loss, medications such as Finasteride (Finpecia 1mg) and Minoxidil (Hair4u 2%) can help 

Conclusion

Hard water vs soft water hair care results have drastic differences. Hard water contains excessive minerals that cause dry and brittle hair. On the other hand, soft water contains minimal minerals, and is therefore, suitable for hair. It makes hair soft, shiny, and manageable.

If you reside in an area with a hard water supply that has damaged your hair, do not worry. The damage caused by hard water is not permanent. It can be reversed with easy steps, such as using soft water to wash hair, clarifying shampoos, scalp massage, and citrus products. 

If you have excessive damage and hair loss, the doctor may prescribe FDA-approved medications like Minoxidil or Finasteride to prevent further damage and regrow hair. So seek medical intervention, if needed. 

With these steps, you can ensure that your hair remains healthy, silky, and shiny.
