Oils are great. Whether you rub them into your hair, skin, or nails before washing to moisturize and remove make-up or use a tiny amount after washing as a moisturizer, they are great. Different oils work differently for different people. Examples of good oils: extra virgin olive oil, coconut oil, jojoba oil, grapeseed oil, etc.The best sunscreens are physical sunscreens, which contain zinc oxide and/or titanium dioxide, with zinc being the best of the two. They are really the only chemicals that truly block both UVA and UVB rays. Remember, sun damage is the #1 cause of aging skin (smoking being #2).Washing your hair less is good for most people. Only wash the scalp and only apply conditioner below the roots.Rinsing your hair with diluted vinegar ~once a week is great for it, it will remove hard-water build up, soothe itchy scalp, help prevent/treat dandruff, and will close the cuticle of the hair making it smoother and shinier. Use ~1 tablespoon vinegar (Apple cider or white, doesn't matter) in 1 cup of water and pour over all of your hair.Heat is bad for your skin and hair. Save that blow drier and straightener for special occasions!Topical vitamin C is amazing for your skin. It clears up acne, prevents wrinkles, helps reverse some sun damage, and just makes your skin glow. However, vitamin C is very unstable and buying products containing vitamin C is a bit of a roulette, as many of them don't contain enough to do anything, and many others are old and the vitamin C has oxidized so it will in fact damage your skin. Solution: make your own vitamin C cream. Take your favorite water-based moisturizer ("water" should be the first ingredient and there should be no oils in the ingredients) and buy vitamin C powder at a health food store. In an opaque or amber container, put in 1000 - 1500mcg (generally one scoop) of vitamin C powder. Add a few drops of filtered or distilled water to dissolve it. Then add 2 tablespoons of moisturizer and mix it up. Voila, ~10% vitamin C cream. Keep your powder in the fridge and make new cream every 2 weeks. If it turns yellow at all, throw it out early.There is no need to buy expensive shaving creams/lotions. I use $1 bottles of conditioner. Lasts longer and keeps legs smoother.Don't keep your razor in the shower. Even just keeping it on the edge of the bath outside the shower curtain will extend it's life by weeks, if not months.Do you buy expensive exfoliating scrubs at the drugstore? Stop! Mix up some sugar (brown or white) with your favorite oil, and add a squirt of lemon juice. After washing your face, rub the sugar/oil mix on gently and rinse it off. This is a very intense exfoliant, so don't use it more than once a week. Can only be used on the entire body.Get hormonal acne at the same time every month? Whether it's around ovulation or before/during your period, aleve can help. Keep track of when it comes, and ~5 days beforehand take 1 aleve a day until ~3 days after it would have come. Then stop. This also can work well for those deep, painful pimples that just won't go away.
