I agree with you but the reality is all you need is a clean face. Certain soaps like dial and zest dry the fukk out of your face so when the hairs try to grow through your dry face it gets irritated and it itches or worse causes bumps because its not coming through the pore but through a scab or a thin layer of skin. This itches and causes bumps then the hair coils up below the surface of the skin and after the irritated sore heals you can usually flake off or scratch off a scab or a piece of dry skin and you have a longer coiled up piece of hair.
The purpose of my post wasn't to discredit yours, like I said I agree. I've been there since I started shaving. Bumping up and scratching, itching. I went through it all, I thought I had bad skin but I've never had acne issues. I knew I had hard water and I know how ashy I used to get when I used Dial on my face and body.
After years of trying different products finally a nikka here put me on to African Soap, I used it (and still do) and my skin is like baby skin.
I have like 6 different razors from cheap bics, to gillete mach 3 to the schtick 5 blade, the vibrator one, one that dispenses lotion etc. Ever since I shaved and used the soap no more bumps, no more itching. I shave my face and neck haven't had an issue since. And I've literally tried like shaving with the grain on my left side and against on the right. Because I know how products work, they may work for a week or a couple months then stop.
This is the soap I (a black man) needs. I like dial, its anti bacterial, I like zest and irish spring (smells good) all these white people bodywashes are cool too but that shyt aint for me. I can't use axe bodywash and shampoo it aint designed for my hair.
Like you I wanna help the nikkas here but instead of buying a myriad of different products just one soap. Its all that's needed.
