It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) did not use depilatory powder; when he (peace and blessings be upon him) had a lot of hair, he would have it shaved.
(b) In this hadith the narrator Muslim al-Mula'i is weak; if he had memorised it accurately, it would be possible that Qatadah narrated it from Sayyiduna Anas (may Allah be pleased with him). Wallahu a'lam (Allah knows best).
