How to get strong and long nails naturally without commercial products

Garlic
Garlic is rich in selenium, which promotes nail growth. You have two options for using garlic on your nails.

Just cut a clove of garlic in half, rub it and massage it into your nails.
Or if that’s too strong for you, you can use garlic oil to make a nail mask. Saute chopped or minced garlic in a pan with a little olive oil for 10 minutes. Make sure the oil is bubbling and not smoking; It will burn healing items. Cool the oil, pour the oil into a glass and discard the garlic pieces. You can massage this oil on your nails and cuticles every morning before washing.
