No black or white. Scalping adds risk by: huge leverage, high trade frequency Scalping reduces risk by: much shorter trade duration, less time in market How one balances those factors is up to the individual trader, ergo the endresult, if scalping reduces risk or increases it, is depending on the person in front of the screen.

It is risky because your commissions eat up your profits and you need to be right really a lot to compensate for it.
I use special account at Hotforex for scalping called raw spread account - almost no spread but fixed commission. it's important to reduce floating part of transaction costs in scalping because you place a lot of trades and you need consistency.
