Here's why:
* Adhesive surface: Bandaid adhesives are designed to stick to skin. Hair gets in the way of this direct contact, reducing the surface area the adhesive can grab onto.
* Friction: Hair creates friction, making it harder for the bandaid to stay in place and can even pull the bandaid off prematurely.
* Pressure: Applying pressure to a bandaid on hairy skin can push the hair into the adhesive, making it less effective.
Tips for better bandaid adhesion on hairy skin:
* Trim the hair: If possible, trim the hair in the area where you need to apply the bandaid.
* Clean the area: Make sure the skin is clean and dry before applying the bandaid.
* Apply pressure: Press down firmly on the bandaid for a few seconds to ensure good adhesion.
* Consider alternative bandages: There are specialized bandages designed for hairy areas, such as those with a "no-stick" border.
