1. Will brushing my hair 100 strokes a day be good for hair growth? Someone told me that it helps with blood circulation.
No. It is bad for it. Brushing pulls your hair out, breaks it off and scratches the scalp. Your hair can get worn out the same as if you repeated brushed a wool sweater. A brush should be used as a styling aid only, not as exercise for the hair. Also, never over comb the hair when it is wet as it is more susceptible to breakage.

2. I have been losing quite a lot of hair lately especially when shampooing. As a result I have cut down my hair washing frequency to 3 times per week? Will frequent shampooing cause me to lose more hair?
No. Everyone’s hair falls out and all hair is eventually replaced. It may be falling out due to metabolic reasons or even stress. Shampooing only loosens the hairs that already have become detached from the follicle’s base. In fact it may encourage faster growth as it has a stimulating effect on the hair follicle. Just like the skin on our face and body needs to be cleanse daily, so does the skin on the scalp. By washing your hair about 3 times a week will most likely cause surface buildup which can easily lead to disorders like dandruff, itchiness and excessive oiliness. This in turn will lead to the possibility of hair loss.
