Haircut Myth

I was about to get my haircut nung sabi ng pinsan ko na bawal daw. Naiirita na ako sa hair ko kasi nagiging oily na sya and it is causing me to feel uncomfortable and stressed out. So, I read some articles kung may scientific basis ang bawal pag gupit ng hair or sabi sabi lang ng matatanda. So here it goes po. Ang alam kong bawal is magdye ng hair or ma expose sa mga chemical hair treatments.
