Biotin will help but it does take time... Just about 6 months. Also don't just go to the drug store and get a biotin supplement. You need to intake 5,000mcg. When a vitamin lists the level this may not be the intake level or the absorbable level. You also need l-cysteine and silica. Look at ELON Matrix 5,000. It is manufactured by a pharmaceutical company and recommended by dermatologists nation wide for thinning hair and nails. I tried it and it worked for me!
