Know your hair porosity! Remedy for dry, damaged hair

Have you had enought with your hair dry and brittle hair? Does it puff up so easily once you step outside, after your working so long and hard on flat ironing and/or styling your hair? Does humidity totally ruin your hair and make you not want to wear your own hair out? Or what about relaxers not taking for you relaxed girls? Does your hair not get straight after relaxing your new growth, even though you leave it on long enough? I KNOW HOW YOU FEEL! My previous post about my HAIR MELT DOWN promted me to do so serious research so I can find out what the heck is wrong with my hair. My research brought me to www.hairfinder.com where I learned about the porosity of hair. Some hair is more porous than others. There is normal hair, low porous hair, and high porous hair. This can happen with relaxed or natural hair! In order to tell you your hair is normal, low or high in porosity, do the strand and water test found here. Snap off a small strand of hair off of your hair (I got a peice at the end of my hair because thats where its very poofy). Drop the strand of hair into a container of water (the container should be clear so you can clearly see the strand of hair). Wait 2-5 minutes to see if your hair FLOATS or SINKS. If you hair sinks, it is pouros. The strand fills up with water causing it to sink. If the strand floats, it is normal/low porous hair. My hair is VERY POUROUS! It only took a couple seconds to sink!! Read more info below to find out how to care for and maintain high and low porous hair! If you hair is prone to get frizzy, dry and break off, it might be exeremly porous. If it refuses to take relaxers or hair color, it may have a very low porosity!   I found out about this shampoo that helps control the porosity of hair. It helps only high porous hair. Check it out on ebay here!

Hair Porosity

       Porosity is the measure of the hair's ability to absorb moisture. This is determined by the condition of the hair's cuticle layer (the overlapping scales of the hair shaft), and is rated as low, normal, and high. In normal, healthy hair, the cuticle is compact and inhibits the penetration of the hair shaft by moisture - both moisture going in, and moisture coming out. When the cuticle is overly compact and prevents the penetration of the hair by moisture it has low porosity.

       Hair with low porosity is harder to process, and is resistant to haircolor and perms. Low porosity hair must usually be softened prior to other chemical services. Hair with high porosity is hair whose cuticle layer is open and the hair too-readily absorbs moisture. Overly-porous hair also releases moisture easily and becomes dry and is easily damaged. Acid-balanced conditioning treatments are used to contract the cuticle layer and lock-in moisture on overly-porous hair.
       Extreme caution must be used when performing chemical services on overly porous hair to prevent damage. Haircolor will take much more quickly and strongly in overly porous hair (and semi-permanent and demi-permanent haircolors will fade much more quickly). Perms and straighteners will process much faster in high-porosity hair as well.

       To determine the porosity of your hair, simply feel it - both when wet and when dry. If the hair feels straw-like and rough when dry, or if it feels gummy or slightly rubbery when wet, then you probably have a problem with overly porous hair. Or you can carry out a hair porosity test.
