ما هي السنة في ترجيل شعر الرأس، وهل فرقه من جانب الرأس فيه تشبه باليهود؟

It is from the Sunnah to honor the hair by washing it, oiling it, and combing it. It has been authentically reported that the Prophet (peace be upon him) used to let his hair hang down, and then he parted it. Accordingly, there is no harm in parting the hair from the side, as long as it is not intended to imitate disbelieving women or men, with the obligation for the Muslim woman to wear complete hijab and not display her hair in front of non-mahram men.
