Cost Cutters sat me down and told me the truth about cheap hair gel. Did you know cheap hair gel can be on the shelf for three years or more? It's true. That’s why it often has so much alcohol. At Cost Cutters they get fresh product every two weeks. If you’re buying gel at the dollar store – my god, how did they know? – you need to watch out for flaking. It could be caused by cheap hair gel and its alcohol (a preservative) drying out your hair and scalp. Thank you, Cost Cutters.
