While there are many home remedies and anecdotal claims suggesting garlic can help nails grow faster or stronger, no scientific research has proven a direct connection between garlic ingestion or application and nail growth.
Some proponents suggest garlic's selenium content may contribute to nail health, but scientific evidence is lacking. However, garlic's strong odor and potential for skin irritation make it an unsuitable choice for frequent nail application.
If you're seeking nail growth solutions, it's best to consult with a dermatologist or healthcare professional for personalized advice.
