The Good: Pyrethrins, for the most part, do seem to be relatively safe for most pets, though dosage is still the key. Many on-line sites list pyrethrins as being safe for cats, and as far as we can tell, used judiciously, they are not too much more toxic for cats than they are for dogs.
Yes: Razor bumps will usually go away when you stop shaving. There are a few things you can do to prevent them in the future. Shave in the shower so the heat can soften the hair, and use a shaving gel. Always use a brand new razor, and shave in the direction that your hair grows. Moisturize after shaving.
You get razor bumps or ingrowns when the hair curls underneath the skin as itâs growing out of the follicle. This usually happens after it has been sliced with a razor or yanked out with wax. When hair is trapped, your body treats it like a foreign invader and attacks it, causing inflammation.
