Is Distilled Water Free From All Impurities?

Yes, distilled water is free from all impurities, toxins, chemicals, and minerals. This purified water maintains a pH of 7. It also is devoid of contamination. Distilled water is produced by boiling regular water and condensing the steam back into the liquid. This process also involves a deionization technique that removes all salts and minerals from the condensed liquid. Distilled water may benefit your hair in many ways. We have discussed the benefits in the next section.

Does Distilled Water Improve Hair Health?

Many cosmetic products consist of nearly 65-70% of water. Manufacturers of cosmetic products use water (distilled water, to be specific) to potentially avoid allergic reactions in users. Distilled water also acts as a solvent and can dissolve all the active ingredients in the products. It also may boost product absorption when used.

Distilled water is one of the purest forms of water that may help promote hair health. Washing your hair with hard water can cause many hair problems. Hard water can deposit minerals like magnesium and calcium in your hair, making your hair dry, frizzy, and fragile. Hair washed with hard water was found to have a rougher appearance and a higher mineral deposition than that washed with distilled water (34/' target='_blank' rel='noopener noreferrer' >26711619/' target='_blank' rel='noopener noreferrer' >1).
