Just as the title says. Do they help or hurt in terms of getting bumps and ingrown hairs?
There's your answer, OP. I've been using one daily for many years.Yes that is the intention along with disinfecting, soothing the skin, closing up nicks, and preventing bacteria.
You tell that to the hundreds of members here who rub all their face after every shave (even if there are no cuts/weepers).There is no use rubbing the face with it unless you are bleeding. And then just the spot is enough.
I Googled it, and yes Alum is not only an astringent, it's also a disinfectant.Yes that is the intention along with disinfecting, soothing the skin, closing up nicks, and preventing bacteria.
Correct answer! Anything one needs to learn about potassium alum is available to research online. Some misinformation posted earlier.I Googled it, and yes Alum is not only an astringent, it's also a disinfectant.
But putting that aside, I use it after every shave simply because of how it makes my face feel.
There is no way to persuade someone that a thing that does nothing is not doing something. Especially shavers, who are a particularly superstitious bunch. Alum, pre-shave oil, cold water shaving, you name it.
Anyway, the most effective treatment for ingrown hairs is acupuncture.
