Duplicating products: Cleansing conditioners
How does the no-shampoo concept work? (This is where I analyze the Wen Cleansing Conditioner. My conclusion: They are no more cleansing than any conditioner you might find in the drug store, but they certainly cost a lot more!)
As for the pH of our body parts, I really need to make this point in bold - you cannot be so out of whack that your skin is alkaline when it is supposed to be acidic. Something like this is very dangerous and can lead to serious skin problems! I can't say this strongly enough. If you have a friend who says things like "My skin is alkaline", she probably has a very serious medical condition or she is wrong.
From this paper on PubMed: Today, the term "normal skin pH" is understood to be the pH value of the surface of the skin of the lower arm of a healthy adult male Caucasian. Its mean value lies in the range 5.4-5.9. In most cases, it is determined by means of a flat glass electrode. The parameter "skin pH" depends mainly on the area of skin and on age, but it also depends to a lesser extent on sex, race and the time of day when values are determined.
As a note, your hair can be anywhere between pH 3.5 and 6.5-ish. For your blood, acidosis is said to occur when arterial pH falls below 7.35, while its counterpart (alkalosis) occurs at a pH over 7.45. Here we see what is a tiny change - only 0.10 pH units - and it can lead to serious health badness!
logarithmic scale, which means that going from 1.0 to 2.0 isn't just an additional 1, it's about the power to 10 to something. 10 to the power of 1 is 10 whereas 10 to the power of 2 is 100. That's a huge difference. 10 to the power of 3 is a thousand - that's massive. So to say your skin should be 5.4 to 5.9 but you think it's over 8 means that you're going from 10 to the power of 5 (100,000) to 10 to the power of 8 (100,000,000). As a note, my multiples of 10 don't have a meaning when it comes to pH - I'm using it as an example of how large a change we see when we use the pH scale.
I'm really not sure how people come to the conclusion that they have alkaline hair or skin, but I hear about it often enough that there must be someone out there somewhere offering testing or information on how to test yourself somehow. You cannot have alkaline skin or hair. It isn't possible. If you have alkaline skin or hair, can you please share where you obtained this information? I'm really curious!
I think I'm going to write a longer post on this topic...I've found such interesting papers on the topic! Look for more to come shortly.
