If there is a lack of any vitamins in the body, then this almost immediately negatively affects the condition of the hair, skin, and especially on the nails. If you begin to notice that your nails have become brittle or periodically exfoliate, then you need to immediately begin to act. First, take care of proper nutrition and, possibly, start drinking vitamin complexes. In addition, old folk recipes can also help.

A ten-minute bath of apple cider vinegar and vegetable oil mixed one to one will solve the problem of brittle nails. For the result to be visible almost immediately, you need to carry out this procedure every two days.
For centuries, Russian beauties have used a simple recipe to strengthen them: they rubbed black or red currant juice into the nail plate and the skin around the nails.
Perhaps one of the most effective means in the unequal fight against the brittleness of our nails are baths with iodized or sea salt. Pour 0.5 liters of water into the bath and dissolve 2-3 tablespoons of salt (regular or sea) in it. Then dip your fingers into the solution so that each nail is covered with it, and soak them in it for a quarter of an hour. After that, dry your hands and then brush them with a nourishing cream. It will be best if you repeat this operation daily. Then within a week you will definitely notice the result: the nails will stop exfoliating and become stronger.
Rubbing lemon juice into the nail plate will help to restore shine to the nails. However, this procedure should not be repeated very often - twice a week is sufficient.
You can prevent brittle nails with daily baths of heated vegetable oil (you can add a small amount of lemon juice). After completing the procedure, blot your hands with a tissue and let the oil soak for several hours. In less than a week, the nails will recover and become strong, and the hands are smooth and tender.
If you are going to do a nail design or manicure soon, then before the procedure itself, it would be best to soak your nails a little in warm water with a small addition of lemon juice. After such a simple procedure, the skin around the nails will soften and remove without any problems.
