[Product Question] Why do shaving creams have such high pH values? Isn't it just as bad as an old-fashioned soap?

Beauty Tips For Body Care
Almost all shaving creams have a pH value >8. A higher pH value may weaken the hair, thereby making the shave easier. But looking at the ingredients and the pH value, a shaving cream is almost like an old fashioned soap. So it may weaken the hair (theoretically), but doesn't it disturb your whole skin fatty acid layer and skin microflora as well? Why are there no companies making very mild pH skin balanced shaving foams, I've never found one that has a pH of about 4-5?So how bad is this high pH value (it feels very stripping to me), does a good shaving cream really have to be this alkaline for it to work? Are most shaving creams not just very stripping soaps? What would be the best most mild alternative to a high pH shaving foam? Is an alternative shaving cream going to provide better results?To mention a few:Proraso Shaving Soap Sensitive Skin - pH9.5Paula's Choice 4MEN - pH8.9-9.9Balea Med Ultra Sensitive Shave Gel - pH8.7
