1. Toothpaste can cure pimples
Yes, toothpaste can dry out pimples. Toothpaste has active ingredients like menthol and other active ingredients that can dry up pimples and make them heal much faster. But toothpaste can also dry up your face so it would be better if you purchased a cream specifically for pimples.
2. Shaving your hair makes it grow back thicker
This is a beauty myth. When you shave your hair it seems to grow back thicker because when we shave our hair the razor cuts the hair to the skins surface. They were not plucked from the follicle, Thats why when the hair grows back,the wide part of the hair grows back making the hair appear thicker.
My mom shaved my head when I was a baby because she thought that it would grow to be thicker, tho my hair is thick it wasn't due to her shaving it. My sisters hair wasn't shaved and her hair is thicker than mine.
3. Mayo is a great conditioner
This is true, mayo is a great conditioner, mayo is rich in fatty acids and protein that nourishes the hair.
