Yes, it is allowable, but if the wax is in bodily form which prevents water from reaching to the skin, then it will be necessary to remove it at the time of wuzu, otherwise the wuzu shall not be valid.
(2) Basically, it is not allowed for a woman to trim her hair. If the hair have grown to a considerable length then it is not permissible to trim it. If the hair are very short which look ugly then it is allowable to trim it as a treatment.
(3) The Prophet (صلی اللہ علیہ وسلم) did so in the beginning, but later he forsook it; therefore one should not do raf?a-yadain.
(4) It is better to cut the nails weekly. If it is not possible then in 15-20 days, but it should not exceed 40 days. If one does not cut it within 40 days he will be sinful.
