Hello,
We have a dedicated Hair, Skin, and Nails Biotin gummy available in our store. It works great for helping with hair and nail growth and strength.
I hope this answers your question. Feel free to reach out directly to us if you have any more questions.
Thank you for contacting Lunakai and have a nice day.
Warmly,
Bella D.
