Re: How should hair be left/tied when going to sleep?
Hi Sangeetha,good question
I have tried both and found that leaving loose hair tends causes hair fall.
So what I suggest is before you go to bed:take a wide-tooth comb and removes all the knots. Tie into a loose ponytail (for short hair) or a braid( for medium/long hair).This way I have observed no hair on pillow/bed.
This also helps from acne point of view because hair does not fall on face also otherwise it will deposit oil,dirt on face and cause pimples!
