Hair is like a water filter
Shooting Stars ask: - Was wondering how hair acquires iron buildup over time.
Hair Fixr reply ~
Hair captures and retains minerals as you shampoo your hair.
Here are some of the more "un-popular" minerals frequently found in water. Iron, silica, lime, copper, calcium, lead, etc,
Look at the water ring in the bathroom stool. The color of the ring will tell you which mineral is predominate in your area.
Brown Rust color = iron from well water and old cast iron pipes found in municipal water systems.
Whitish crusty = lime, calcium, silica from well water.
Aqua Green = new homes with copper plumbing.
Mucky brown/gray = lead from well water.
Any of these minerals can cause havoc in a hair color formula.
How it happens: - When you stand under the extra warm shower stream, the cuticle layer of the hair opens up from the water temp. The hair acts like a filter as the body's "negative" magnetic attraction holds the "positive charged" minerals in place. As you Rinse the shampoo/conditioner off - the PH of the shampoo closes the cuticle layer of the hair hence trapping the minerals under the cuticle layer of the hair shaft. Day after day of this procedure builds up enough minerals that even virgin hair "no color" is changed enough that a professional colorist can tell. Blonds get warmer over time, Browns loose the Auburn luster, Brunettes get dull, the side effects are endless.
For you short hair girls - this is less of a issue as you keep the hair cut short so the serious build up is removed by regular haircuts. For the long hair styles it becomes a issue to deal with. Mineral build up is what makes hair appear dry and un-manageable many times. Think about what is making the ring in the stool - that is what is going on in the hair :eek:
When I was in Oklahoma I had my clients use a treatment when ever they felt they needed it to remove the hard water mineral build up. Ask your colorist what they suggest for your area. Every area differs with severity of minerals ;)
Note: The new home water filter systems are great for dealing with this issue. The older salt water treatment systems for hard water will not.
