Good night and happy new year !!!

I read about a herb in the Vedas (the Rig Veda I think) to prevent hair fall. But the name of this herb was in Sanskrit language as far as I can remember and I couldn't find someone to help me know which herb, where to find it, if that was real...

Does anyone know about that ??? can help me to decipher it ?

Thank you for your help,
Best Regards,

Eternity
