Does violating the custom of a girl not removing armpit and pubic hair until marriage constitute a violation of the Sunnah of the Messenger of Allah (peace and blessings be upon him), and is it permissible for the female groomer to see the girl's major 'awrah for hair removal?

This habit is contrary to the Sunnah of the Messenger of Allah, peace and blessings be upon him, as it is narrated in the Two Sahihs that the Prophet, peace and blessings be upon him, said: "The fitra (natural disposition) is five things, or five things are from the fitra: circumcision, shaving the pubic hair, plucking the armpit hair, clipping the nails, and trimming the mustache." "Istihdad" (shaving the pubic hair) is the shaving of the pubic hair. These practices should not be left for more than forty nights, as narrated by Muslim that Anas said: "A time limit was set for us for trimming the mustache, clipping the nails, plucking the armpit hair, and shaving the pubic hair, that we should not leave them for more than forty nights." As for the beautician or anyone else looking at what is unlawful for them to look at from the girl, it is undoubtedly forbidden. The scholars have unanimously agreed that it is not permissible for anyone other than the husband to look at the private parts except in cases of necessity or need that are similar in meaning, such as treatment.
