Beer as a substitute for hair spray
Try to give the hair a perfect grip with very simple means. Quite simple and it really works and is absolutely harmless to your hair. Buy a can of beer (pils) from Aldi or Lidl for a few cents in a shopping center, fill it into a nebulizer, and spray in the morning if you want to give your hair a firm hold, like with hairspray. Then you give the finishing touch with the brush. It may smell like beer for a while, but the smell goes away after a few minutes. There are no scales and it does not hurt your hair. Leaves no marks on pillows or sheets, do not worry.
