What are the verses used for healing from weak and falling hair?

There are no specific verses for fulfilling needs or for ruqyah (exorcism/healing through Quranic recitation). However, it is permissible for a Muslim to recite a surah or a verse and then ask Allah for whatever they wish, based on the general prophetic tradition: "Whoever recites the Quran, let him ask Allah by it." The Prophet, peace and blessings be upon him, also recommended treating the sick with the Book of Allah. And the entire Quran is a healing and mercy for the believers.
