I have been taking biotin for my hair and nails to grow is there anything else i can to to make them grow faster?

Protein diet: A high protein diet may help as well as taking beta carotene.

No: Biotin has been shown to be useless. No vitamins or anything else will make nails grow faster. You may have hair and nail changes because of recent surgery. There may be hormone changes which your drs can address. See a dermatologist if the changes are significant. Eat vegetables, fruits, etc. There is a huge baggage of silly nonsense on this subject. Don't be a sucker.
