The first thing you need to do is to peel the onions to get rid of their skin. Cut the onions into big chunks. For instance, cutting an average sized onion into four parts would work.
Depending on the size of the juicer, place a few chunks of onion in the juicer. Make sure that you do not stuff the juicer to its limit. Seal the juicer by placing the lid on top of the juicer.
Turn on the juicer at normal speed. Gradually increase the speed until the juicer reaches its maximum speed. Let it run for approximately one minute at its full speed.
Turn off the container and clean it by taking a handful of onion mash out at a time and juicing it. Make sure all the onion juice falls back into the juicer. Make sure that you do this step slowly to avoid clogging the juicer.
Pour the contents of the juicer into a glass jar and store it in a refrigerator.
When you wish to use onion juice for your skin, shake the glass jar properly and pour the desired amount of onion juice in a glass. Set aside the glass for about an hour so that the juice comes back to room temperature.
Cover both hands with a pair of gloves and soak a sterile cotton ball in the onion juice. Wipe the affected skin with this cotton ball. At the start, repeat this treatment at least twice every week. At the end of the second week of your treatment, you can feel hair growth begin once again.
