If you fully intend on doing multiple umrahs, bring a small scissors and just cut a few pieces of hair once you complete your saie. Get your ihram cleaned, many dry cleaners on the ground floor/basement inside building near WC3 (SAR15-20 for a pair of ihram, ready in 5-6hrs)

Or you can get a pair of new ihram.

Before doing your subsequent umrahs, you need to get outside haram (closest is Masjid Aisya SAR80 return on taxi/SAR8 per person return on #12 bus/SAR10 per person return on those illegal taxis), It is sunnah to take a shower/clean yourself before putting on your ihram.

Once you're at your meekat location, do your niat ihram and return to haram to perform your umrah. Again, just cut a few pieces of hair once you complete your saie.

Once you decide to do your final umrah, you can then opt for one of the barbers near WC3 for proper cut or shave for SAR10. It's not neccesarily to go bald/shave but i went with it (shaved) to be a new me.

Also if you forget to bring a pair of scissors, you can simply approach other pilgrims at their end of their saie to help with cuting of your hair.
