Moisture is the single most important factor in determining the way your client's hair extensions look!
When moisture content of the hair drops below 10-10.2% (depending on the type of hair and the level of environmental humidity), hair looks like brittle straw as opposed to supple green grass.
The critical moisture level is the difference between a fresh slice of bread and one left on the counter for 3 days.
In the example of the straw or the stale slice of bread, if we apply the slightest pressure, they will break. The same pressure on the fresh slice of bread or the green grass shows us how malleable these materials could be.
Likewise, any pressure put on dry human hair, as opposed to well-moisturized hair, will result in breakage.
Simply put, dry hair leads to breakage, especially with repeated combing applied in a localized area.
Moisture content = Strength of the hair
For human hair, these figures explain the fiber's strength and the amount of pressure it can withstand before breaking.
"gn/m²" stands for "Giganewtons per square meter," which is a measure of pressure.
This means that dry healthy unprocessed hair can withstand more pressure before breaking than dry processed hair.
The important lesson here is that any type of moisture will increase the strength of the hair by up to 300%!
Every test we have conducted on hair has shown that plain water is as effective as any conditioner or leave-in moisturizer
For example, try wearing your jeans after washing them, while they are still soaking wet and feel the roughness of the fabric.
This has to do with the swelling and increased strength of the fiber weave when wet.
Until the water evaporates, the denim will be significantly stronger.
Damaged hair when wet will stretch and eventually break apart as it does when dry, but it takes more pressure.
How we developed our bleaching recipe
The use of the moisture content analyzer was critical in helping us fine-tune our bleaching recipe.
You cannot be dependent upon only look and feel.
Basing results on numbers gives us factual indicators on whether or not the hair is reducing in moisture content at a normal rate or significantly more compared to another recipe.
By testing selected bundles from every batch and testing the fibers’ moisture percentage, we were able to optimize the best formula for lifting the Indian Remy hair from its virgin dark brown to the lightest bleached blond colors without compromizing quality control standards.
Conditioner vs. regular water
Conditioner will add strength, but only temporarily, just as water will.
Now we are getting to one of the major tradeoffs between conditioner and water:
In hot desert climates such as in Arizona and Nevada, it is extremely important to maintain the moisture of the hair extensions, especially if the client spends any time in the sun.
Just a few minutes of ultra-violet exposure on treated hair is enough to make a significant impact.
In these conditions, a very light leave-in conditioner is highly recommended.
