Whilst many of these habits are pretty common, experts say they could be damaging to your health.
Using spray products
Whether it's hairspray, deodorant or fake tan, products that come in an aerosol can be dangerous as they release chemicals into the air which you shouldn't inhale. If you use spray products, always make sure to use them in a well-ventilated area.
Taking hot showers
Whilst taking a nice hot shower at the end of the day may feel relaxing, it could have horrible effects on your skin. According to experts, the combination of hot water and harsh soaps can strip your skin of moisture - exacerbating skin conditions like acne and eczema. Be kind to your skin and keep the temperature lukewarm instead.
Getting a gel manicure
Whilst gel manicures can look great and have long-lasting effects, they are also a health hazard. This is because the UV nail dryer that is used can increase the risk of skin cancer - just like a tanning bed.
Sharing your mascara
If a friend asks to borrow your mascara or eyeliner it can feel hard to say no - but you absolutely should! Sharing eye makeup products can lead to eye infections which can have really nasty consequences - just don't do it.
Using a loofah
You may think they're harmless but loofahs are a breeding ground for nasty bacteria, mould and fungus - especially if you leave it hanging in your shower. This can lead to skin rashes and even nasty infections like staph.
