I used hairpro to wash my hair once or twice a day for more than a week.
When I didn't wash my hair with hairpro during day time and I washed my hair with hairpro, that's night time. During day time I felt my hair 'oily' and not 'thick', after some time, I noticed that there are many pimples appeared on my top left and right back head compare to other brand hair shampoo (Pantene) that I used previously.
When I wash my hair with hairpro during day time and night time, it seems pimples gradually reducing, but not fully gone.
