Does Garlic Really Make Nails Grow Faster? - What the Science Says
There is no scientific evidence to support the claim that garlic promotes nail growth. Some people believe that the allicin in garlic, which has antimicrobial and antifungal properties, might improve nail health by preventing infections, which could indirectly contribute to healthy nail growth. However, applying garlic directly to your nails can cause skin irritation or allergic reactions.
