You can achieve naturally thick eyelashes safely and inexpensively without even leaving your house. The ingredients for naturally thick and longer eyelashes are right inside your medicine cabinet -- or at your nearest health food store. Add these steps to your daily beauty regimen and in weeks you may be able to toss your mascara and fake eyelashes for good. Whatever the outcome, your lashes will definitely be in better shape than they were before.

Practice regular grooming of your lashes as you do your hair. Brush your lashes twice a day using an eyelash brush or comb. You can also use a clean mascara brush if you don't have an eyelash brush. Add a few drops of vitamin E oil to the brush, or apply directly onto the lashes. Vitamin E oil helps prevent lashes from shedding. Daily brushing stimulates lash growth and makes your lashes look softer and thicker.

Apply olive oil to your lashes. Olive oil is widely used to strengthen hair and stimulate hair growth. Apply a few drops on a cotton ball and dab on eyelashes. Leave it on for five minutes, then rinse off with tepid water. Do this for four weeks or until you get desired results.

Vaseline stimulates hair and lash growth. Apply to your lashes before going to bed at night and rinse off with warm water in the morning. Vaseline is a good substitute if you don't have vitamin E on hand for your nightly lash-brushing ritual. Just add it to your lash brush and brush through your lashes.

Make sure your daily supplements include vitamins that promote lash growth and strength, such as vitamins B, D and E. These vitamins keep the eyelashes strong enough to withstand the wear and tear that comes with the daily use of mascara or eyelash curlers. These vitamins also promote hair growth.

Remove all traces of eye makeup from the eye area, especially your lashes. Any good eye makeup remover, or even cold cream, will do the trick. Avoid roughly tugging or rubbing when you remove our eye makeup to protect your lashes as well as the sensitive skin around the eye.

Ditch the eyelash curlers for a while, or stop using them entirely. According to the Become Gorgeous website, the use of eyelash curlers sabotages your best efforts because they weaken the lashes and can cause breakage. Also consider going without mascara, or occasionally wear fake lashes until you reach the desired results with your lash-thickening efforts.
