Is it true that … you need to detox your scalp?

Scalp detox products do not remove dangerous toxins, but occasional deep cleaning may help people with product buildup. Hard water and urban pollution can leave additional residue, although an expensive specialist treatment is not necessarily required.

头皮排毒产品并不能清除危险的毒素，但偶尔进行深层清洁可能有助于去除美发产品的堆积物。硬水和城市污染也会在头皮上留下残留物，不过人们未必需要购买昂贵的专业护理产品。
