There are number of minerals present in water, these minerals can effect your  hair health. Some of the unhealthy effects of these minerals are as follows:-

• Calcium makes hair to feel dry, diminish shine and volume. It can prevent the proper processing of color, highlights, perms or relaxer/straighteners and can cause a perm to appear relaxed. Calcium builds up on the scalp causing flaking of the scalp, giving the appearance of dandruff. Calcium can choke the hair at the mouth of the follicle causing the hair to break off, and then coat the scalp, blocking further new hair growth.
• Iron can cause water to have a red or rusty tone. Iron leaves hair feeling dry, brittle and weighted down. It causes lack of shine and can cause dark hair to tint darker and blonde hair to turn orange. Iron can inhibit the proper processing of perms, color, highlights, and relaxers/straighteners.
• Copper discolors hair causing blonde hair to turn green and dark hair to tint darker. Copper can weigh hair down and cause dryness, and can inhibit the proper processing of perms, color, highlights, and relaxers/straighteners.
• Magnesium causes hair to lack shine, feel dry, appear weighted down therefore lacking volume, and can inhibit the proper processing of perms, color, highlights, and relaxers/straighteners.
• Silica causes many of the same effects on the hair as calcium. It causes hair to feel dry, lack volume, and can cause dandruff-like symptoms of flaking. Build-up of silica can choke the hair follicle causing hair to fall out.
• Lead can cause the hair to feel dry. Lead can prevent the proper processing of perms, color, highlights, and relaxers/straighteners.

Remedial Measures against minerals in water

To improve the hair health and further prevent issues with dryness and buildup, populace can use a shower head filter that will remove the minerals found in most city waters. The sanitizing agents like Chlorine and Chloramines can also deposit in or on the hair, building up over time. Filtering water through very fine mesh cloth may help to remove larger deposits in the water. Treatment for hard water conditions is available in a variety of products, such as demineralizing shampoos and conditioners.
