Wash that Man right outta your Hair

This week in Cosmo School we are on Shampooing . Sounds like it may be simple, right? I mean every one has shampooed their hair. I get they want you to learn how to massage the clients head, while giving a shampoo, body posture so we don't get back aches. There's more....a lot more.
Not just any old shampoo will work on all hair types. There is the pH scale to consider. Is the hair colored, relaxed, permed, dry, oily? All that to know which is the best shampoo for a particular hair type.
Most people don't realize that their shampoo alone can wreck havioc on the hair. We buy whats on sale, or what smells good. There's a discussion going on at school on whether or not Salon Shampoos are really better than some thing you buy off the shelf at Walmart. It all has to do with pH levels, conditioning properties. No wonder we stand in the asile for 20 min. just trying to pick out hair care products.
We are going through the basics of Chemistry later on. I am sure it will go into deeper detail of the pH scale , the ingredents in shampoo, as well as conditioners, and rinses.
In the mean time I have been doing research on the net to get some insider info., as well as getting my own little science experment going by testing shampoos. I think I may ask the teacher if we all bring in a sample of our shampoos for pH testing. That may be a neat class project.
I will let you know how that came out.
