Hi mommy. Iba iba kasi ng rate ng pagheal ang katawan natin. But definitely ung sugat sa loob for CS takes months or sometimes even years before magheal. That’s why ang recommendation parati is to get pregnant atleast 18 months to 2 years after CS delivery. And madami restrictions mommy. Lalo na sa pagbubuhat ng mabibigat. Regarding haircut. I think you can have a haircut anytime after giving birth. I did that 2 months after I gave birth.
